Description

  The present invention relates to a packaged mandarin orange and a method for producing the same. Specifically, the present invention relates to a packaged mandarin orange that can be uncooked and eaten as it is, and a method for producing the same.

  As for the actual situation of food sales in recent baseball stadiums, movie theaters, and trains, there is a tendency to refrain from things that may require extra labor at the time of cleaning or may cause problems in hygiene. As a result, sales of foods that inevitably produce garbage are hardly accepted.

  For example, when selling regular mandarin oranges, it is necessary to remove the husk when eating the mandarin orange, and the removed husk becomes garbage, so in the state as it is (the husk has not been removed) It is difficult to obtain a sales permit.

  Patent Document 1 states that “a cut piece is stuck on a required portion of a food body such as fruit or boxed food, and only the entire surface of the food body and only the base or the entire surface of the cut piece are peelable. Disclosure of a food product made by coating a harmless resin film excellent in the condition of standing upright, and as a specific example, the state that the tip of the cutting piece is upright at an appropriate part of the apple A non-corrosive resin film that adheres to the food hygiene law with excellent peelability by spray coating or dip coating on the entire surface of the apple and the entire surface of the cut piece, and then sticks in the tangential direction to maintain. And then the resin film is dried by a tunnel-type heat drying method ”.

  However, as described in Patent Document 1, for the “apple with a coating on the surface”, in general, when taking into account that “the core of the apple does not eat”, the core when eating the apple Since the remaining core portion becomes garbage, it can be said that it is difficult to obtain a sales permit in the state as it is (the state where the core portion is not removed).

  On the other hand, there is a real need to eat mandarin oranges in baseball fields, movie theaters and trains.

  Patent Document 2 states that “a fruit selected from mandarin oranges, peaches and persimmons is a packaged fruit in which the entire skin has been removed and covered with a coating film, and the coating film is attached to the fruit. There is a description of “packaged fruits in which a film-forming liquid is cured and formed so that a coating film can be peeled off from fruits”.

  However, such a technique cannot be said to be sufficient in the following points.

That is, when the coating film forming liquid is cured to form a coating film, the fruit (mandarin orange) from which the outer skin has been removed is immersed in the coating film forming liquid. As a result, the coating film-forming liquid penetrates into the pores (ie, the gap between the particles wrapped in the endothelium).
And when a coating film formation liquid hardens | cures in the state which the coating film formation liquid permeated into the hole which a mandarin orange has, it will become very difficult to peel a coating film from a mandarin orange main body.

In consideration of immersion in the coating film forming liquid, it is necessary to keep the coating film forming liquid in a liquid state so that the coating film forming liquid does not solidify. It is necessary to keep the film-forming liquid at a predetermined temperature.
However, if the mandarin orange body is immersed in the coating film forming liquid maintained at such a predetermined temperature, the quality of the mandarin orange body may be impaired due to the influence of heat from the coating film forming liquid to the mandarin orange body. obtain.

Furthermore, when a coating film is formed by immersing a mandarin in a coating film forming liquid and curing the coating film forming liquid attached to the mandarin orange body by immersing, the mandarin orange body is coated with the coating film forming liquid. However, the amount of the coating film forming liquid adhering to the upper side and the lower side of the mandarin orange main body is different due to the influence of gravity during the lifting. Specifically, the amount of adhesion is small above the mandarin orange main body, and the amount of adhesion is large below the mandarin orange main body. As a result, the film thickness of the coating film is thin above the mandarin orange main body, and the coating is below the mandarin orange main body. A difference in the film thickness of the coating film occurs, such as a thick film.
And the amount of dust will increase because the coating film becomes unnecessarily thick under the mandarin orange body.

  In addition, when a coating film is formed by immersing a mandarin in a coating film forming liquid, it is difficult to deal with general-purpose facilities, and a new capital investment is required for realization.

  The present invention was devised in view of the above points, and an object of the present invention is to provide a packaged mandarin orange that can meet the needs of eating a mandarin orange in a baseball field, a movie theater, or a train, and a method for manufacturing the same. To do.

  In order to achieve the above-mentioned object, the packaged mandarin orange of the present invention can peel the whole mandarin orange body by removing the outer skin and having the particles encased in the endothelium and heat-treating the film. And a coating film coated thereon.

  In order to achieve the above object, the method for producing a packaged mandarin orange of the present invention includes a step of wrapping a mandarin orange body having grains encapsulated in endothelium with the outer skin removed, and the above-described wrapping with the film. A step of heat-treating the mandarin orange main body so that the entire mandarin orange main body is releasably covered with the film.

  Here, by removing the outer skin of the mandarin orange body covered with the coating film, the food covered with the coating film (mandarin orange body) is “a food that does not produce garbage”. And, by covering these “foods that do not produce garbage” with a coating film, there is an effect that it can be sold in baseball fields, movie theaters, trains, etc. without the occurrence of garbage. Expect to play.

  In addition, the packaged mandarin orange of the present invention and the packaged mandarin orange obtained by the method for producing the packaged mandarin orange of the present invention do not generate dust at all, and the coating film needs to be disposed of as garbage. However, since the coating film is classified as general garbage instead of raw garbage, it does not hinder sales in baseball fields, movie theaters, trains, and the like.

In addition, since the coating film is substantially in close contact with the citrus body, almost no air is interposed between the citrus body and the coating film, and quality deterioration of the citrus body can be suppressed.
That is, when air is present between the coating film and the mandarin orange main body, the presence of the air may impair the flavor of the mandarin orange body or change its color. Therefore, it is possible to suppress deterioration of the quality of the mandarin orange main body by excluding air between the mandarin orange main body and the coating film.

  In addition, it becomes possible to maintain quality over a long period of time by freezing the mandarin orange body covered with the coating film. Also, for example, Satsuma mandarin is usually harvested from October to January, and is a seasonal product until around the end of March, but it is sold throughout the year by freezing the mandarin orange body covered with a coating film. It is possible to promote sales through effective use of the market.

  The packaged mandarin orange and the method for producing the same of the present invention can realize a “food that does not produce raw garbage”, and can fully meet the need to eat mandarin oranges in baseball fields, movie theaters, and trains. .

Hereinafter, embodiments of the present invention will be described with reference to the drawings to facilitate understanding of the present invention.
FIG. 1 is a schematic diagram for explaining an example of a packaged mandarin orange to which the present invention is applied. A packaged mandarin orange 1 shown here is composed of grains 3 that are encased in light skin (endothelium) 2 with the outer skin removed. It is comprised from the mandarin orange main body 4 and the coating film 5 which coat | covers the mandarin orange main body 4.

  Here, the coating film 5 is composed of a heat-shrinkable film and is detachable from the mandarin orange main body 4, and also plays a role as a packaging material for the mandarin orange main body 4.

  In addition, when removing the coating film 5 from the mandarin orange body 4 (peeling), a force is applied in the direction indicated by the symbol A in FIG. a)), the one surface side of the coating film 5 is separated into two (see FIG. 2B), and the mandarin orange body 4 is taken out from the gap 7 generated by separating one surface of the coating film 5 (See FIG. 2 (c)).

Here, in the example of the packaged mandarin orange to which the present invention is applied, the case where the knob 6 is provided on the coating film 5 is described as an example, but the coating film 5 is peeled from the mandarin orange body 4. It is sufficient if it can be done, and the knob 6 does not necessarily have to be formed.
However, in consideration of ease of peeling of the coating film 5 from the mandarin orange body 4, it is preferable that the knob portion 6 is formed.

  FIG. 3A (a) is a schematic diagram for explaining another example of the packaged mandarin orange to which the present invention is applied. The packaged mandarin orange 1 shown here is encased in a light skin (endothelium) 2 with the outer skin removed. A mandarin orange body 4 made of crushed grains 3, a coating film 5 which is in close contact with the thin skin 2 of the mandarin orange body 4 and covers the mandarin orange body 4, and a part of the coating film 5 is embedded and the other part is outside It is comprised from the string 8 exposed to.

Here, the coating film 5 is composed of a heat-shrinkable film and is configured to be peelable from the mandarin orange body 4 (specifically, the thin skin 2), and also serves as a packaging material for the mandarin orange body 4 Plays.
The string 8 may be any material as long as it does not adversely affect the quality of the mandarin orange body 4.

  By the way, when removing the covering film 5 from the thin skin 2 of the mandarin orange body 4 (peeling), first, the exposed portion of the string 8 is picked with a finger and the string 8 is pulled away from the covering film 5 to cover the covering film 5. The film 5 is separated into two (see FIG. 3A (b)).

  Here, after the string 8 is separated from the coating film 5, if a hole can be made in the coating film 5 in order to make the coating film 5 easy to remove, the length of the string 8 embedded in the coating film 5 is Any length of the bath, for example, a length corresponding to one round of the mandarin orange main body 4 or a length corresponding to a half circumference of the mandarin orange main body 4 may be used.

  Thereafter, the coating film 5 separated into two parts is peeled from the mandarin orange body 4 (see FIG. 3A (c)).

Here, in another example of the packaged mandarin orange to which the present invention is applied, the case where the string 8 is embedded in the coating film 5 is described as an example, but the coating film 5 is peeled off from the mandarin orange body 4. It is sufficient if it can be done, and it is not always necessary to embed the string 8 in the coating film 5.
However, considering the ease of peeling of the coating film 5 from the mandarin orange body 4, it is preferable that the string 8 is embedded in the coating film 5.

  FIG. 3B (a) is a schematic diagram for explaining still another example of the packaged mandarin orange to which the present invention is applied. The packaged mandarin orange 1 shown here is encased in a thin skin (endothelium) 2 with the outer skin removed. The mandarin orange main body 4 is composed of the separated grains 3 and a coating film 5 that is in close contact with the thin skin 2 of the mandarin orange main body 4 and covers the mandarin orange main body 4. The thin skin 2 and the grains 3 are the same as those in FIG. 3A, and are not shown in FIG. 3B.

  Further, one end of a member simulating the shape of a leaf is bonded to the coating film 5 using an adhesive (not shown), and the other end of this member functions as a knob 6.

  Here, the coating film 5 is composed of a heat-shrinkable film and is configured to be peelable from the mandarin orange body 4 (specifically, the thin skin 2), and also serves as a packaging material for the mandarin orange body 4 Plays.

  When the coating film 5 is removed (peeled) from the thin skin 2 of the mandarin orange body 4, a force is applied by sandwiching the knob 6 attached to the coating film 5 with a finger, and the two coating films 5 are applied. The mandarin orange main body 4 is taken out in a state separated into (see FIG. 3B (b)).

Here, in yet another example of the packaged mandarin orange to which the present invention is applied, the case where the knob 6 is provided on the coating film 5 is described as an example. It is sufficient if it can be peeled off, and the knob 6 does not necessarily have to be formed.
However, in consideration of ease of peeling of the coating film 5 from the mandarin orange body 4, it is preferable that the knob portion 6 is formed.

  Hereinafter, the manufacturing method of the packaged mandarin orange comprised as mentioned above is demonstrated. That is, an example of a method for producing a packaged mandarin orange to which the present invention is applied will be described. In addition, in FIG. 4, illustration is abbreviate | omitted about the manufacturing method of another example of the packaged mandarin orange to which this invention is applied.

  In the manufacturing method of the packaged mandarin orange to which the present invention is applied, first, the outer skin 10 of the mandarin orange body 4 is removed (see FIG. 4A).

Specifically, for example, the whole mandarin orange body 4 is soaked in hot water at about 100 ° C. and passed through a roller with teeth to remove the outer skin 10.
The thin skin (endothelium) 2 covering the grains 3 of the mandarin orange body 4 is left without being removed, and the white linear streaks on the thin skin 2 are removed.

Next, the mandarin orange body 4 from which the outer skin 10 has been removed is wrapped with a heat shrink film (for example, a polypropylene film) 9 (see FIG. 4B).
The heat shrink film 9 is cut in advance so as to have a size suitable for enveloping the mandarin orange body 4.

  Here, when manufacturing an example of the packaged mandarin orange to which the above-described present invention is applied, a knob portion 6 is provided in advance on the heat-shrinkable film 9, and the mandarin orange main body 4 is formed with the heat-shrinkable film 9 provided with the knob portion 6. Envelop.

  On the other hand, when manufacturing another example of the packaged mandarin orange to which the present invention is applied, the string 8 is embedded in the heat shrink film 9 in advance, and the mandarin orange body 4 is made of the heat shrink film 9 in which the string 8 is embedded. Envelop. In addition, when manufacturing another example of the packaged mandarin orange to which the present invention is applied, the mandarin orange body 4 is wrapped with a heat shrink film 9 in which the string 8 is not embedded.

  Subsequently, the heat-shrinkable film 9 enclosing the mandarin orange body 4 is subjected to heat treatment, thereby forming a coating film 5 that covers the mandarin orange main body 4 in a completely sealed state with the heat-shrinkable film 9 (FIG. 4C). reference). In addition, when manufacturing another example of the packaged mandarin orange to which the above-described present invention is applied, after forming the coating film 5, a leaf-shaped member is bonded to form the knob portion 6.

  The heat treatment for the heat-shrinkable film 9 is sufficient as long as the heat-shrinkable film 9 can adhere a portion necessary for forming the coating film 5 that covers the mandarin orange body 4, and the heat-shrinkable film 9 is heated for such a long time. There is no need to do.

  Here, the film for forming the coating film 5 is not necessarily the heat-shrinkable film 9, and any material can be used as long as the coating film 5 for covering the mandarin orange body 4 can be formed.

  Thereafter, the mandarin orange body 4 covered with the coating film 5 is subjected to a freezing treatment, whereby a packaged mandarin orange to which the present invention is applied can be obtained.

Here, in the example of the method for producing packaged mandarin orange to which the present invention is applied, the mandarin orange body 4 covered with the coating film 5 is subjected to the freezing treatment, but the freezing treatment is not necessarily performed.
However, in order to maintain the quality of the mandarin orange body 4 over a long period of time and to prevent the quality from deteriorating during transportation to a baseball field, a movie theater, a train, etc., it is preferable to perform a freezing treatment.

  In the packaged mandarin orange to which the present invention is applied and the packaged mandarin orange obtained by the method for producing the packaged mandarin orange to which the present invention is applied, it is possible to realize “a food product that does not produce garbage”, in a baseball field, a movie theater, a train It is easy to obtain a sales permit in the city, and it is possible to sufficiently meet the need to eat mandarin oranges in such places.

  In addition, the fact that the sale of mandarin oranges was unavoidable due to the occurrence of raw garbage was changed completely by the packaged mandarin orange to which the present invention was applied, and the mandarin oranges were sold as "food that does not produce raw garbage". Can open up new channels for mandarin oranges.

  In addition, since the coating film 5 is formed by heat-treating the heat-shrinkable film 9, it covers the pores of the mandarin orange body 4 (that is, the gaps between the grains 3 wrapped in the thin skin 2). The covering film 5 does not enter, and the covering film 5 can be easily peeled from the mandarin orange body 4.

  Furthermore, since the heat treatment applied to the heat-shrinkable film 9 is not so long, it is considered that the quality deterioration of the mandarin orange body 4 due to the heat treatment is very little affected.

  In addition, it is considered that the facility that heat-treats the heat-shrinkable film 9 can be sufficiently handled by existing facilities, and is not forced to invest in a new facility, so that its feasibility is extremely high.
