Description

  The present invention cools and solidifies jelly sterilized on an in-line, then passes through a primary filter to form, and mixes the formed jelly with fluid sterilized food and drink into a secondary filter. It is related with the manufacturing method of the food-drinks containing jelly characterized by making it pass and crush.

  Food materials that have solidified gelling agents (carrageenan, gellan gum, gelatin, pectin, agar, etc.) are generally added directly to foods that have fluidity as well as food forms that can be eaten directly as jelly and enjoy its texture. By doing so, jelly-containing foods and drinks having both the characteristics and functions of jelly and fluid food that allow you to taste different textures simultaneously have been provided.

  For example, beverages containing jelly (Patent Documents 1 and 2), yogurt containing jelly (Patent Document 3), and the like are known. A production method in which the solidified jelly is cut into a predetermined size and added to the fluid food after heat sterilization so that it can be ingested as a fluid food or beverage while tasting the texture of the jelly. It has been.

  As described above, when the solidified jelly is added to the flowable food, the jelly that has been solidified (gelled) and cut is added again immediately before the addition in order to aseptically add to the food. It was necessary to sterilize by heating. Sterilization is indispensable for providing a sanitary and safe food, and heat sterilization is widespread as the most excellent method as a safe and proven sterilization method. However, if the thermoreversible gel is heated, the jelly cut to an appropriate size will dissolve and become too small, the solid shape may disappear, or it may be refrigerated afterwards. Sometimes a fluid food or beverage becomes gelled as a whole. Therefore, the fact that the jelly used can maintain the shape of the cut jelly even by heat sterilization, that is, the gel does not dissolve again by heating, is an important factor that becomes a manufacturing constraint, Due to restrictions, it has become a common technique to use a gelling agent (jelly substrate) having a heat-resistant (thermal irreversible) property.

  From the viewpoint of avoiding this restriction, in order to add the cut jelly to the food without re-sterilization by heating, the jelly preparation line and the food production line to be added are integrated into a sealed line structure. A technique related to the manufacturing method (Patent Document 4) has been developed.

  However, in the technique disclosed in Patent Document 4, it is necessary to install a dedicated jelly cutting machine near the inlet of the mixing tank in the manufacturing process of the jelly preparation. The increase in size was inevitable. In addition, due to the structural features, the cooling and solidifying process of the jelly is performed in the line, and the cutting process is performed immediately thereafter. For this reason, the type of jelly base material that can be used in manufacturing is limited in order to ensure that gelation proceeds rapidly and sufficient gel strength is obtained in a short period of time from when the jelly is cooled to solidified. However, another limitation such as the need to use the jelly substrate in an excessive amount is newly generated.

Japanese Patent Laid-Open No. 7-322867 JP 7-67593 A JP 9-37712 A JP 2002-191302 A

  As described above, in conventional jelly-containing foods and drinks, it is necessary to perform heat sterilization at the final stage of the production process from the viewpoint of storage stability, and heat resistance (thermal irreversibility) is sufficient to withstand heat sterilization conditions. Because hard jelly using jelly base material that forms a gel as a raw material was added to foods and drinks, it seems to be incompatible with fluid foods, such as bad throat and unable to eat unless chewed Had problems.

  Moreover, since the food-drinks after jelly addition are heat-sterilized again, there also existed a problem that the range of applicable food-drinks was restrict | limited.

  Moreover, also in the well-known technique which tried not to heat-sterilize the food / beverage products after jelly addition again, the kind of jelly base material which can be used for manufacture is restrict | limited, and a jelly base material must be used in quantity excessively.

However, the present invention is not limited to the preferred embodiments exemplified below, and can be freely modified within the scope of the present invention. In the present specification, percentages are expressed by mass unless otherwise specified.

The present invention is a method for producing a jelly-containing food or drink,
Dissolving a jelly raw material containing a jelly base material, sterilizing by heating, and preparing a jelly raw material liquid;
The prepared jelly raw material liquid is introduced into the cooling unit, cooled and solidified while moving in the cooling unit to prepare the jelly, and the prepared jelly is integrated with the cooling unit in series at the downstream end of the cooling unit. A step of preparing a rod-shaped jelly by passing the first filter portion provided in

A step of producing a jelly-containing food or drink by filling a container with the prepared small piece jelly or food or drink preparation,
In a method comprising.

According to this method, after the jelly raw material is once heat-sterilized, the jelly-containing food / drink is mixed with the fluid food / beverage prepared by sterilization and filled in the container. Since it is carried out in a connected closed system and manufactured without being contaminated, there is no step in which the jelly prepared from the jelly raw material is subjected to heat sterilization again. For this reason, it is possible to produce a jelly-containing food / beverage with an excellent texture by using a jelly base material that is not heat-resistant because it is excellent in texture but cannot be used in conventional manufacturing methods. it can.
In addition, since cooling and solidification of the sterilized jelly raw material liquid can be achieved while the pipe is moving, the jelly is prepared from the jelly raw material without using a storage tank for cooling and solidifying the jelly raw material liquid, and enters the jelly. A food or drink can be produced.
Furthermore, according to this method, since it is possible to manufacture by a system connected through a pipeline, it is possible to continuously and efficiently manufacture food and drink containing jelly.

  FIG. 1 is a flowchart illustrating an outline of one embodiment of the present invention. FIG. 2 is an explanatory diagram illustrating an outline of an apparatus that can suitably implement the present invention. The jelly-containing food / beverage products according to the present invention are prepared by first preparing jelly and fluid food / beverage products separately, and then mixing them. This flow will be described below with reference to FIGS. 1 and 2. The process proceeds from the top to the bottom in FIG. 1 and from the left to the right in FIG.

  The jelly raw material is put into an arbitrary tank, stirred and dissolved in this tank, sterilized by heating to become a jelly raw material liquid, and then temporarily stored in the liquid storage tank (preserve tank) (1 in FIG. 2). Is done. The jelly raw material liquid stored in the liquid storage tank (1 in FIG. 2) is connected in series with the cooling part (4 in FIG. 2) and the first filter part (5 in FIG. 2) by the rotary pump (3 in FIG. 2). It is sent out (introduced) to the pipe line that is installed in. The jelly raw material is gradually cooled and solidified while moving through the cooling part, and the solidified jelly is prepared at the end point (downstream end part) of the cooling part and moves through the flow path in the pipeline. Yes. Subsequently, the solidified jelly passes through the first filter part (primary filter part) (first filter part) (primary cutting filter part) (5 in FIG. 2) (the left part of the chart in FIG. 1). The filter unit can include one or more filters, and 5 in FIG. 2 shows a filter unit composed of a single filter. The jelly that has passed through the first filter part (5 in FIG. 2) is passed through the filter hole of the filter part and sent out to form a rod-like jelly having a cross section corresponding to the shape and size of the hole. (First molding), the flow path is further sent as it is, and it reaches the mixer (dozer) (11 in FIG. 2).

The fluid food (food or drink) is prepared in a base tank (7 in FIG. 2) prepared in a sterilized state, and sent to the flow path by a rotary pump (9 in FIG. 2) (FIG. 1). To the mixer (11 in FIG. 2).
The state prepared by sterilization means a state prepared hygienically by performing necessary sterilization according to the food. For example, in the case of fermented milk, it means a state in which lactic acid bacteria starter and the like are added in a sanitary state after necessary sterilization is performed on the raw material, fermented, and subjected to processing such as homogenization as desired. In addition, the fermented milk contains a state in which live bacteria such as lactic acid bacteria that are important are included. That is, as long as necessary sterilization is performed according to the food and it is in a sanitary state, it naturally includes a state in which living microorganisms are included.

  The rod-shaped jelly that has reached the mixer (11 in FIG. 2) and the fluid food are mixed (dosed) in the mixer (center portion in FIG. 1) to become a mixture (bar-shaped jelly / food product preparation). . The rod-shaped jelly / food product preparation is further sent through the flow path and passes through the second filter part (secondary filter part) (second filter part) (secondary cutting filter part) (13 in FIG. 2). (The center part of FIG. 1). The rod-shaped jelly that has passed through the second filter portion (13 in FIG. 2) is sent through the hole of the filter, so that the orientation of the rod-shaped jelly when passing through the hole, the shape and size of the hole that passes through the hole. In accordance with this, it is formed into a small piece of jelly (second forming). As a result, the mixture of rod-shaped jelly and food / beverage products (bar-shaped jelly / food / beverage product preparation) becomes a mixture of small pieces jelly and food / beverage products (small piece jelly / food / beverage product preparation) by passing through the second filter section. The small piece jelly / food product preparation is delivered to the filling machine (17 in FIG. 2) by a rotary pump (15 in FIG. 2). In the filling machine (17 in FIG. 2), the small piece jelly / food product preparation is filled in the container without being contaminated (center portion in FIG. 1), and the jelly-containing food product is manufactured.

  In the manufacturing process shown in FIGS. 1 and 2, the jelly raw material liquid prepared as a sterilized liquid in the liquid storage tank (1 in FIG. 2) is then contaminated through a sealed flow path (pipe). The flowable food (food / beverage) prepared in a state of being sterilized and prepared in the base tank (7 in FIG. 2) reaches the filling machine without being closed, and then the sealed channel (pipe) ) To reach the filling machine without being contaminated, no heat sterilization in the filling machine is required. In this way, in the production of jelly-containing food and drink, the heat sterilization is not required again by installing the cooling unit and the first filter unit in series, the mixer, and the second filter unit. There are advantageous features of the invention.

FIG. 3 is an explanatory diagram of a portion (a dotted line portion in FIG. 2) for performing a step of preparing a rod-like jelly in the apparatus in FIG.
That is, the process from the prepared jelly raw material liquid to preparing the rod-shaped jelly is shown. First, the jelly raw material is dissolved, sterilized by heating with a sterilizer to prepare a jelly raw material liquid, and this jelly raw material liquid is put into a liquid storage tank (preserve tank) (1 in FIG. 3).
The prepared jelly raw material liquid is supplied to the cooling part of the pipe line in which the cooling part (4 in FIG. 3) and the first filter part (5 in FIG. 3) are installed in series by the rotary pump (3 in FIG. 3). It is sent out (introduced) to the upstream end.
In the present invention, the cooling part and the first filter part are integrally provided, and the jelly raw material is sterilized by cooling and solidifying the jelly and cutting the jelly only by moving in the pipeline. A rod-like jelly can be prepared from the liquid.
In the present invention, it is possible to prepare a rod-like jelly safely, hygienically, and simply by using the above-mentioned pipeline.

As an example of the cooling unit that can be suitably used in the present invention, a combination of a straight pipe (straight pipe) and a U-shaped pipe (4 in FIG. 3) can be mentioned. These combinations are preferable because the apparatus can be installed compactly.
The cooling unit of the present invention is not limited to the one shown in FIG. 3, but includes any one of a straight tube, a U-shaped tube, a tube having a bent portion (R tube), and a spiral tube, or a combination of two or more types of tubes. It may be.

  The jelly raw material liquid sent to the cooling unit gradually cools and solidifies while moving inside the cooling unit, and when it passes through the end point of the cooling unit, the jelly raw material solution reaches the center of the cylindrical cross section. Solidified and jelly is prepared. The prepared jelly is continuously sent to the first filter unit (5 in FIG. 3) provided integrally with the cooling unit, and passes through this. And the jelly which passes is passed through the filter installed in the 1st filter part, is cut | judged by this, and becomes a rod-shaped jelly.

  FIG. 4 shows a tube having a cooling part for cooling and solidifying a jelly raw material liquid, and a first filter part integrally provided on the downstream side of the cooling part, which can be suitably used in the production of the jelly of the present invention. An example of a path is shown. In FIG. 4, the cooling pipe (4 in FIG. 4) of the cooling unit is a double pipe comprising an inner pipe and an outer pipe installed so as to cover the inner pipe, and a jelly raw material liquid (jelly liquid) is placed inside the inner pipe. ) Flows, and the refrigerant flows between the outer tube and the inner tube. It is preferable that the jelly raw material liquid is completely solidified at the end of the cooling section.

  Water, an aqueous solution (for example, a saline solution) or the like can be appropriately used as the refrigerant for the cooling pipe, but water is most preferably used. The refrigerant is preferably circulated and reused while being cooled. Although the temperature of a refrigerant | coolant can be suitably adjusted, it can be 0-34 degreeC, for example, Preferably it is 0-25 degreeC, More preferably, it is 4-15 degreeC. In a preferred embodiment, the jelly raw material liquid before being charged into the cooling unit usually has a temperature of 50 to 65 ° C, but is cooled to about 5 to 15 ° C by passing through the cooling unit, It becomes a solidified jelly, which is sent to the first filter section.

  In a preferred embodiment, when a double-pipe cooling pipe is used, it is preferable that the refrigerant delivery direction is opposite to the jelly raw material delivery direction. Thereby, the high temperature jelly raw material liquid immediately after being introduced from the upstream end of the moving direction of the jelly raw material liquid in the cooling pipe comes into contact with the refrigerant whose temperature has already increased due to heat exchange, while the cooling pipe Since the jelly raw material liquid whose temperature has been lowered by moving is brought into contact with a refrigerant having a low temperature immediately after being introduced into the cooling pipe, efficient cooling can be achieved. In FIG. 4, such a preferable flow direction is illustrated by arrows. 4 represents the flow direction of the jelly raw material liquid, and the left arrow of FIG. 4 represents the flow direction of the refrigerant. The jelly raw material liquid is introduced from the upstream end of the cooling section, flows rightward inside the double pipe structure cooling pipe (4 in FIG. 4) in FIG. 4, and solidifies at the downstream end of the cooling section. And immediately passes through the first filter section (5 in FIG. 4).

  The inner diameter of the cooling pipe of the cooling section used in the present invention is not particularly limited, but the inner diameter of the cooling pipe is preferably 7 to 47.2 mm, more preferably 10.5 to 35.4 mm, and particularly preferably 14 mm to 23.23 mm. It can be 6 mm. If the inner diameter of the cooling tube is 7 mm or less, the solidification is too early and the possibility of the tube closing is increased. Further, when the inner diameter of the cooling pipe is 47.2 mm or more, the cooling is insufficient and the whole is difficult to solidify.

In a preferred embodiment, the total length of the cooling pipe is appropriately set according to the inner diameter of the cooling pipe. For example, when the inner diameter of the cooling pipe is 14 mm, the total length of the cooling pipe is preferably 2 to 15 m, more preferably 3 to 8 m, and particularly preferably 4 to 4.5 m.
For example, when the inner diameter of the cooling pipe is 23.6 mm, the total length of the cooling pipe is preferably 5 to 72 m, more preferably 20 to 54 m, and particularly preferably 34 to 36 m.

The jelly raw material liquid introduced into the cooling unit is cooled and solidified in the cooling unit to become jelly, and subsequently flows into the first filter unit installed in series with the cooling unit at the downstream end of the cooling unit. .
The jelly that has flowed into the first filter portion (5 in FIG. 4) is cut by passing through the first filter portion to form a rod-like jelly.

  One first filter portion is provided on a disk-shaped plate having a thickness of about 0.1 to 10 mm provided to close the flow path in a cylindrical pipe line serving as a flow path (line) or Two or more holes are provided. The jelly that has reached the filter passes through a hole made in the disk because the pipe is blocked by a disk-shaped plate (disk) and is sent through the flow path. When passing through the hole, the jelly is cut and cut according to the shape and size of the hole and the orientation of the jelly when passing through the hole.

  The size and shape of the hole on the filter is not particularly limited as long as there is a hole on the filter to the extent that a suitable pressure is applied to the jelly because the jelly is cut. However, it can be used if there is a hole in a certain area ratio. Specifically, the ratio of the total area of the holes opened on the filter per cross-sectional area of the pipe line (the disk area of the filter installed in the first filter part) is preferably 10 to 50%, 15 -45% is more preferable, and 20-45% is particularly preferable.

Moreover, although it can implement if one filter is installed in the 1st filter part, two or more filters may be installed.
When there are two or more filters in the first filter section (hereinafter sometimes referred to as the first filter), the rod-shaped jelly that has passed from the first filter passes through the second filter, The jelly is further subdivided, and the burden of the second filter part fragmenting the jelly is reduced.
The number of filters to be installed is not limited, but when the number of filters is five or more, the degree of variation of the jelly pieces becomes almost constant, and the maintenance burden due to the increase in the number of filters increases.
Accordingly, the number of filters installed in the first filter section is preferably 1 or more and 10 or less, more preferably 1 or more and 5 or less, and more preferably 1 or more and 3 or less.

  Even when two or more filters are installed in the first filter section, the thickness of the filter to be installed and the number, size, and shape of the filter holes do not have to be the same. Filters can be combined as appropriate.

  Further, when two or more filters of the first filter section are installed, the distance between the filters is not particularly limited, and can be appropriately set to desired manufacturing conditions. When two or more filters are installed as the first filter unit, mixing and stirring means such as a static mixer may be incorporated between the filters. For example, by installing a static mixer between the filters, the rod-like jelly that has passed through the previous filter can pass through the next filter while being mixed and stirred by the effect of the static mixer and changing the direction. Jelly cutting is possible.

  FIG. 5 shows a front view of an example of the disk of the first filter. In FIG. 5, five substantially square holes are formed in the disk that closes the duct. The shape of the hole can be substantially square, but it can also be triangular, quadrangular, pentagonal, hexagonal, more polygonal, circular, elliptical, star, or other shapes. In a preferred embodiment, a hole having a substantially regular triangle, a substantially square, a substantially regular pentagon, and a substantially regular hexagon, and more preferably a substantially regular triangle or a substantially square can be used. These holes can be mixed in different shapes. In these plane figures, the largest diagonal line is a regular polygon, the diameter is a circle, the longest diameter is an ellipse, and the longest width is shown in this specification. Okay, the size of the hole is represented by this major axis.

  The first filter has a hole having a long diameter of preferably 2 to 10 mm, more preferably 3 to 9 mm, further preferably 3 to 8 mm, more preferably 4 to 7 mm, and further preferably 4 to 6 mm. The number of holes in the filter can be increased as desired when the diameter of the disc becomes large according to the diameter of the conduit that becomes the flow path, but the diameter of the disc becomes large. Even in this case, the preferable range of the major axis of the hole is as described above. The number of holes in the filter is changed with the guideline that the flow velocity (linear flow velocity) of the flow path described later will be in the preferred range when the diameter of the disc increases or decreases according to the diameter of the pipe line that becomes the flow path. can do.

The flow rate through which the jelly raw material passes through the cooling part and the first filter part is constant, and depends on the cross-sectional area of the pipe line, the total length of the pipe line, the temperature when the jelly raw material is charged, the temperature of the refrigerant, the thermal conductivity of the soot, etc. It is preferable to set it within a preferable range as appropriate.
Among the various conditions described above, the flow rate of the jelly raw material is particularly dependent on the inner diameter of the tube, and therefore varies depending on the tube.
That is, the flow rate at the time of passing through the first filter part is, for example, 8.7 to 20.5 kg / h / cm ² , preferably 8.7 to 15.0 kg / h / cm ² as a linear flow rate, Preferably it is the range of 8.7-14.1 kg / h / cm < ² >.

FIG. 7 is an explanatory diagram showing an outline of another example of an apparatus that can suitably implement the present invention.
FIG. 7 shows two filters (5a and 5b in FIG. 7) as the first filter unit (5 in FIG. 7) installed in series with the cooling unit, and the second filter unit (13 in FIG. 7). It is an apparatus in which two filters (13a and 13b in FIG. 7) are respectively installed. As in FIG. 1, the jelly raw material liquid that has been sterilized and introduced into the liquid storage tank (preserve tank) (1 in FIG. 7) is cooled by the rotary pump (3 in FIG. 7) and the cooling unit (4 in FIG. 7). The first filter section (5 in FIG. 7) is sent out (introduced) to a pipeline formed in series. The jelly raw material liquid is gradually cooled and solidified while moving the cooling part, and the solidified jelly is prepared at the end point of the cooling part. The solidified jelly then reaches the first filter section (5 in FIG. 7), passes through the first filter (5a in FIG. 7), becomes a bar-shaped jelly cut, and then the second filter (see FIG. 7). 7 is cut further by passing through 5b). Further, the cut bar-like jelly reaches the mixer (dozer) (11 in FIG. 7) through the pipe as it is. As in FIG. 2, the liquid food (food and drink) prepared in the base tank (7 in FIG. 7) prepared and sterilized separately and sent to the flow path by the rotary pump (9 in FIG. 7) Product) also reaches the mixer (dozer) (11 in FIG. 7). The rod-shaped jelly that has reached the mixer (11 in FIG. 7) and the fluid food (food / drink) are mixed (dosing) in the mixer in the same manner as in FIG. 2, and the mixture (rod-shaped jelly / food / drink) Preparation). This mixture (rod-like jelly / food / drink preparation) is further sent out through the flow path, and by two filters (13a and 13b in FIG. 7) installed in the second filter part (13 in FIG. 7), The jelly pieces are cut into a mixture of small pieces jelly and food / beverage products (small piece jelly / food product preparation). Since the number of times of cutting increases by increasing the number of filters in the filter portion, the jelly can be sufficiently cut and variations in the size and shape of the jelly can be suppressed. As in FIG. 2, small pieces of jelly and food / beverage preparations are sent to a filling machine (17 in FIG. 7) by a rotary pump (15 in FIG. 7), filled into a container without being contaminated, and filled with jelly. Foods and drinks are manufactured.

FIG. 8 is an explanatory diagram showing an outline of another example of an apparatus that can suitably implement the present invention.
The apparatus shown in FIG. 8 includes a facility for temporarily holding a rod-like jelly by a cooling part and a first filter part, and then temporarily holding it in a holding container, for example, a preservative tank (23 in FIG. 8). In the apparatus of FIG. 8, first, the sterilized jelly raw material is aseptically charged into the hopper (19 in FIG. 8). The jelly raw material is sent out by a rotary pump (21 in FIG. 8), and sent (injected) into a pipe line in which a cooling part (4 in FIG. 8) and a first filter part (5 in FIG. 8) are installed in series. The The jelly raw material gradually cools and solidifies while moving the cooling part, and the solidified jelly is prepared at the end point of the cooling part. The solidified jelly subsequently passes through two filters (5a and 5b in FIG. 8) of the first filter section (5 in FIG. 8) and is aseptically held in the preserve tank (23 in FIG. 8). The held rod-like jelly is again sent to the pipeline by the rotary pump (25 in FIG. 8), and reaches the mixer (dozer) (11 in FIG. 8) through the pipeline. As in FIG. 2, the liquid food (food and drink) prepared in the base tank (7 in FIG. 8) prepared and sterilized separately and sent to the flow path by the rotary pump (9 in FIG. 8) Product) also reaches the mixer (dozer) (11 in FIG. 8). The rod-shaped jelly and the fluid food (food / drink) that have reached the mixer (dozer) (11 in FIG. 8) are mixed (dosing) in the mixer in the same manner as in FIG. 2, and the mixture (rod-shaped jelly / food / drink) Preparation). This mixture (rod-like jelly / food / beverage product preparation) is further fed through the flow path and cut into jelly pieces by one filter installed in the second filter section (13 in FIG. 8). It becomes a mixture of jelly and food and drink (small piece jelly and food and drink preparation). As in FIG. 2, small pieces of jelly and food / beverage preparations are sent to a filling machine (17 in FIG. 8) by a rotary pump (15 in FIG. 8), filled into a container without being contaminated, and filled with jelly. Foods and drinks are manufactured.
In FIG. 8, the number of filters in the second filter section (13 in FIG. 8) is one, but two or more filters can be installed.
By using this equipment, the solidified jelly from the preserve tank can be easily sent to the flow path, or the jelly can be cut and stirred in advance so that the jelly is about the size of the diameter of the flow path. it can.
A holding container is a container for once holding | maintaining the rod-shaped jelly sent from the upstream process, and sending it out to a downstream process again. If it is a container which can be used for such a purpose, it can be used as a holding container, for example, a preserve tank can be used. By providing such a holding container and once holding the rod-shaped jelly, the amount of the rod-shaped jelly mixed in the mixer can be controlled to reduce fluctuations.

  Also in the manufacturing process described with reference to FIGS. 7 and 8, the jelly and fluid food (food and beverage) that have been input reach the filling machine without being contaminated, and thus heat sterilization in the filling machine is not required. Thus, in the production of jelly-containing foods and drinks, there is an advantageous feature of the present invention in that re-sterilization by heating is not required by installing the first filter unit, the mixer, and the second filter unit.

  The jelly raw material includes a jelly base material (gelling agent) for forming jelly. According to the present invention, as a jelly base material, a jelly (gel) that is formed while being excellent in texture is non-heat-resistant, so it is not suitable for heat sterilization, and as a result, a flowable food containing jelly (jelly) It is possible to use a jelly base material that could not be used for food and drink). Accordingly, examples of a jelly substrate that can be suitably used include a jelly substrate that forms a jelly that is non-heat-resistant or thermoreversible and has an excellent texture. However, a heat-resistant or heat-irreversible jelly substrate can be used alone or in combination as a jelly substrate. Suitable jelly substrates that can be suitably used include, for example, carrageenan, agar, fur celerane, locust bean gum, mannan and xanthan gum, preferably carrageenan, agar, fur celeran, locust bean gum, and mannan. Carrageenan, agar, and far celerane are preferable. For example, a jelly containing carrageenan as a main component is preferable because it has a non-heat-resistant property and provides a unique texture. In addition to the above, xanthan gum, tamarind gum, pectin, and sodium alginate can be exemplified as a jelly base material that can be added and used. The exemplified components can be used alone or in combination of two or more as the components of the jelly base material as desired. According to the present invention, it is possible to freely select a combination of such components by paying attention to the texture without being restricted by the heat resistance requirement of the jelly (gel). In an embodiment of a preferred embodiment that makes use of the advantages of the present invention, for example, in the case of a jelly mainly composed of carrageenan, the mass of the carrageenan is most contained among the other jelly substrate components. It is desirable that it is contained in the same amount or more as the mass. Specifically, when one component other than carrageenan is included in the jelly base component, the mass of carrageenan is 50% by mass or more, and two components other than carrageenan are included in the jelly base component. In this case, the mass of carrageenan is 33.4% by mass or more, and when 3 components other than carrageenan are included in the components of the jelly substrate, the mass of carrageenan is 25% by mass or more. When 4 components are included in addition to carrageenan, the mass of carrageenan is 20% by mass or more, and when 5 components other than carrageenan are included in the jelly base component, the mass of carrageenan is 16.7% by mass. The above is preferable.

  The non-heat-resistant jelly in the present invention includes a jelly once formed as a gel, which has a property (thermo-reversible) that dissolves again by heating, and even if it does not completely dissolve by heating. Including jelly that loses its shape and texture before heating.

  The content of the jelly base contained in the jelly raw material can be selected according to the desired texture of the jelly, but when the entire jelly raw material is 100 parts by mass, the content of the jelly base is, for example, 0.01 to 3.0 parts by mass, preferably 0.05 to 3.0 parts by mass, more preferably 0.1 to 2.0 parts by mass, and still more preferably 0.2 to 2.0 parts by mass. It can be.

A coloring agent, a pigment | flavor, a fragrance | flavor, fruit juice, puree, a preservative, an extract, a pH adjuster, alcohol, a vitamin, a mineral, etc. can be added arbitrarily.

The jelly formed from the jelly raw material is sent out and passes through the first filter portion to become a rod-like jelly, and then passes through the second filter portion to become a small piece of jelly. At the same time, the jelly has a texture suitable for jelly-containing foods. For this reason, in an embodiment of a preferred embodiment of the present invention, the jelly is preferably 20 to 650 g / cm ² , more preferably 50 to 500 g / cm ² , more preferably 100 to 450 g / cm ^2. It has strength, and preferably has a breaking distance in the range of 5 to 30 mm, more preferably 6 to 20 mm, and even more preferably 7 to 16 mm.

A compression test is conducted by moving the plunger into the sample at a moving speed of 60 mm / min, and means the breaking strength when the gel (jelly) breaks. The breaking distance means the plunger required to reach this breaking strength. Means the approach distance.

  One second filter section is provided on a disk-shaped plate having a thickness of about 0.1 to 10 mm provided to close the flow path in a cylindrical pipe line serving as a flow path (line) or Two or more holes are provided. The jelly that has reached the filter passes through a hole made in the disk because the pipe is blocked by a disk-shaped plate (disk) and is sent through the flow path. When passing through the hole, the jelly is cut and shaped according to the shape and size of the hole and the orientation of the jelly when passing through the hole.

  The size and shape of the hole on the filter is not particularly limited as long as there is a hole on the filter to the extent that a suitable pressure is applied to the jelly because the jelly is cut. It is possible if the holes are open at a constant area ratio. Specifically, the ratio of the total area of the holes opened on the filter per cross-sectional area of the pipe line (the disk area of the filter installed in the first filter part and the second filter part) is 10 to 10. 50% is preferable, 15 to 45% is more preferable, and 20 to 45% is particularly preferable.

In addition, the method of the present invention can be achieved if one filter is installed in the second filter section, but two or more filters may be installed. When there are two or more filters in the second filter section (hereinafter sometimes referred to as second filters), the jelly pieces that have not been sufficiently cut even after passing through the first filter are separated into small pieces. Can be cut into jelly.
Thus, when two or more second filters are installed, it is possible to reduce variation in the size of the cut jelly pieces and to obtain jelly pieces having a uniform size.
The number of filters to be installed is not limited, but when the number of filters is five or more, the degree of variation of the jelly pieces becomes almost constant, and the maintenance burden due to the increase in the number of filters increases.
Therefore, the number of filters installed in the second filter section is preferably 1 or more and 10 or less, more preferably 1 or more and 5 or less, and more preferably 1 or more and 3 or less.

Further, the number of holes in the first filter is preferably smaller than the number of holes in the second filter. The number of holes in the filter can be increased as desired when the diameter of the disc becomes large according to the diameter of the conduit that becomes the flow path, but the diameter of the disc becomes large. Even in this case, the preferable range of the major axis of the hole is as described above. The number of holes in the filter is changed with the guideline that the flow velocity (linear flow velocity) of the flow path described later will be in the preferred range when the diameter of the disc increases or decreases according to the diameter of the pipe line that becomes the flow path. can do.

Then, the mixture was cooled to room temperature and mixed and immersed in a 4-fold concentrated grape juice: jelly at a ratio of 1: 3 to obtain a jelly of Comparative Example 3 containing glucomannan as a main component.

[Jelly breaking test]
With respect to the jelly of Example 3 and Comparative Examples 1 to 3 prepared as described above, the breaking strength and breaking distance were measured under the following conditions.
Measuring instrument: Sun Science Rheometer COMPAC-100
Measurement temperature: 10 ° C
Measurement method: Measured by placing a 120 ml plastic cup on a rheometer sample stage Sample stage ascending speed: 60 mm / min
HOLD: 10g
Axis used: Contact portion diameter 10mm
The breaking strength and breaking distance were measured by pressing down once using a sun rheometer (Rheometer COMPAC-100, manufactured by Sun Kagaku Kogyo Co., Ltd.). Value. The measurement conditions were such that the plunger diameter was 10 mm, the range width was 0 to 10 kg, and the sample stage ascending speed (plunger entry speed) was 60 mm / min.

As a result, the break strength was 420 g / cm ² and the break distance was 12.0 mm in Example 3 (jelly having carrageenan as a main component), and the break strength was 134 g / in in Comparative Example 1 (preparation of jelly having gellan gum as a main component). cm ² , and the breaking distance was 3.4 mm. Further, in Comparative Example 3 (jelly having glucomannan as a main component) and Comparative Example 4 (jelly having glucomannan as a main component), the jelly is not solidified, and is a very soft and highly viscous fluid state. Therefore, it was in a state not suitable for the test of breaking strength and breaking distance, and could not be measured.

  As described above, the jelly containing carrageenan as a main component has a large breaking strength and breaking distance, is rich in elasticity, and is able to satisfy a smooth texture. On the other hand, jelly containing gellan gum as a main component has a small breaking strength and breaking distance, is poor in elasticity, and is brittle and easily broken. Moreover, the jelly which has a glucomannan as a main component was in the state which should be a highly viscous fluid, and was a result which showed that it was inadequate to taste the sense of eating.

[Comparison of food and drink with jelly]
In order to compare the jelly-containing food and drink according to Example 1 prepared as described above and the jelly-containing food and drink according to Comparative Example 4 which are different in Example 1 in that the jelly base material is gellan gum, the following examination was performed. It was. In addition, since the jelly of Comparative Examples 2 and 3 was not hardened and was extremely soft and highly viscous, it was in a state not suitable for the following comparison, and thus was not examined.

[Preparation of food and drink containing jelly] (Example 1)
A food / beverage product containing jelly mainly composed of carrageenan by the fermented milk containing grape jelly described in Example 1 was prepared as a sample for the following sensory test.

[Preparation of food and drink containing jelly] (Comparative Example 4)
Mainly gellan gum produced in the same manner as the fermented milk containing grape jelly described in Example 1 except that the jelly base material was changed to jelly mainly composed of gellan gum described in Comparative Example 1. A food and drink containing jelly as an ingredient was prepared and used as a control sample for the following sensory test.

[Sensory test]
For the food / beverage products containing jelly of Example 1 and Comparative Example 4 (jelly yogurt containing jelly) prepared as described above, “Measuring deliciousness-Actual food sensory test” (Hideko Furukawa, Sachishobo, published in 1994) In accordance with the test method on page 21, the sensory test was conducted as follows.

For 20 skilled panelists, the food and drink containing the jelly of Example 1 and Comparative Example 4 (yogurt containing jelly) were eaten in 50 g increments at room temperature, and the answers to the following questions were obtained. .
Question Q1. Which of the following do you feel the jelly is firm? Q2. Which of the following do you feel the jelly feels good? Q3. Which do you feel the jelly texture is good?

  The results are shown in Table 5 below.

  There was a significant difference between Q1 and Q3 responses (0.1% for Q1 and 1% for Q3). There was no significant difference in Q2 answers.

  As described above, the jelly-containing yogurt (Example 1) using jelly mainly composed of carrageenan has sufficient hardness to feel that it has been eaten as well as the texture of the jelly. It was a thing. On the other hand, the jelly-containing yogurt (Comparative Example 4) containing gellan gum as a main component is insufficient in hardness as the texture of the jelly, and the texture is not good.

[Comparison of melting point of jelly]
In order to compare the melting points of the jelly contained in the jelly-containing food and drink, the following jelly samples were prepared and experiments were conducted.
That is, each jelly sample of Example 3, Comparative Example 1 and Comparative Example 2 was put into a 200 ml beaker and heated in a hot water bath to visually check how the jelly sample was dissolved, The temperature at that time was measured.

[Results of melting point measurement]
The jelly sample of Example 3 began to melt at about 48 ° C and completely melted at about 53 ° C.
The jelly sample of Comparative Example 1 started to melt at about 74 ° C. and completely melted at about 78 ° C.
The jelly sample of Comparative Example 2 was heated (heated) to 85 ° C., but the gel-like substance was not melted and no change due to heating was observed.

  Thus, the jelly containing carrageenan as a main component cannot withstand the heating up to a sterilizable temperature. The jelly containing gellan gum as a main component can withstand a certain degree of heating up to a temperature at which it can be sterilized. The jelly mainly composed of glucomannan was sufficiently resistant to heating up to a sterilizable temperature. However, as before the heating, the jelly should be considered as a viscous fluid rather than a jelly. I kept it.

[Examination of jelly cutting conditions]
In this test, in order to examine the cutting conditions of jelly, the relationship between the number of filters in the first filter part and the second filter part and the size of the jelly pieces after cutting was examined. In addition, the optimum conditions for the aperture (hole size) of the filter were also examined.

1) Preparation of grape jelly Grape jelly was prepared by the method of Example 1.

2) Preparation of fermented milk (paste-like fermented milk) The fermented milk raw material was prepared by the method of Example 1.

3) Manufacture of fermented milk containing grape jelly 150 g of the grape jelly prepared in 1) above is put into a stirrer under aseptic conditions, and the jelly is fed into a cylindrical pipe line with a line diameter of 1 inch extending from the stirrer with a rotary pump. The first filter part installed in the was cut while passing at a linear flow rate of 34.6 kg / h / cm ² to prepare a rod-like jelly.

  The prepared rod-like jelly is passed through the paste-like fermented milk prepared in 2) above and a cylindrical pipe line with a line diameter of 1 inch using a static mixer so that the mixing ratio is jelly: fermented milk = 3: 7. By mixing, about 500 g of a rod-like jelly / fermented fermented milk preparation was prepared.

The prepared rod-like jelly / fermented fermented milk preparation is subsequently fed into a cylindrical pipe line with a line diameter of 1 inch, and passed through a second filter section installed in the pipe line at a linear flow rate of 284 kg / h / cm ^2. While the rod-shaped jelly was molded into small pieces of jelly, small pieces of jelly and pasty fermented milk preparations were prepared.

  Only the jelly was taken out from the obtained small piece jelly / paste-like fermented milk preparation and washed, and the major axis of any 50 pieces of the jelly pieces was measured.

4) Combination of filters As a filter of the first filter part, a filter having a square hole with a piece of 6 to 9 mm was used. In addition, a filter having a square hole of 5 mm or 6 mm in one piece was used as the filter of the second filter part. The number of filter holes varies depending on the size of the filter holes.
When the piece of filter hole is 9mm, the number of holes is 1, when the piece is 8mm, the number of holes is 2, and when the piece is 7mm, 6mm, 5mm, the number of holes is 2, 3 respectively. There were five.

  The test results are shown in Table 6. In Test Examples 1 to 6, 1 to 3 filters were used for the first filter part, and 1 to 2 filters were used for the second filter part. "-" In the table means that no filter is used. Moreover, the numerical value of 5-9 described in a 1st filter part and a 2nd filter part means one side of the opening (hole) of a filter. The average major axis is the average value of the major axes of 50 jelly pieces, and the major axis is the length of the diameter of the longest part of the jelly pieces that have passed through the first and second filter parts. The standard deviation was calculated from the length of the major axis of 50 jelly pieces. In addition, the unit of the numerical value in a table | surface is all millimeters (mm).

In Test Example 1, when one filter having two squares having a major axis of 7 mm was used for the first filter part and one filter having five squares having a major axis of 5 mm was used for the second filter part, the average major axis was obtained. Was 13.8 mm and the standard deviation was 4.2 mm.
In Test Examples 2 and 3, when two filters were installed in the first filter portion, the average major axis became shorter and the standard deviation, which is an index of variation, decreased.
In Test Example 4, three filters were installed in the first filter portion, but no significant difference was observed compared to the case of two filters.
In Test Examples 5 and 6, when two filters were installed in the second filter portion, the average major axis was further shortened.

A jelly piece having a large average major axis and little variation is preferable because it has a uniform texture. In this test, the variation of the average major axis was confirmed by the standard deviation.
Therefore, all the results of this test can be said to be good results. Among them, the result of Test Example 2 in which two filters of the first filter part are installed and one filter of the second filter part is installed is the most. It became good.

  According to the present invention, there is no restriction on the use of the base material used for the jelly raw material, and it is possible to add jelly to various fluid foods and drinks, so that the jelly has a new texture that has never been seen before. Entered food and drink can be provided. Moreover, according to this invention, compared with the former, the manufacturing process of the food-drinks containing jelly can be simplified, and manufacturing cost can be reduced significantly. Therefore, the present invention is an industrially useful invention.
