Description

  The present invention relates to a method for producing a fruit and fruit paste such as plum, peach, plum, etc. and a separation apparatus for seeds and paste pulp used in the production, and in particular, separates raw plums and seeds from raw plums to produce jelly, jam, etc. The present invention relates to a method for producing a nuclear fruit paste suitable for producing a ume paste that can be used as a secondary processed food, and a device for separating seed and paste pulp used in the production.

  Plum fruit has long been prized as a health food, and has been used as a popular food that is closely related to daily life. The effect of plum is said to be various, and is said to have fatigue recovery, cough, especially antibacterial and antiallergic effects. In this way, the Japanese apricot has long been popular with Japanese people, but the plums are mainly used only for plum pickles and plum wine, and are rarely used as secondary processed foods.

As a secondary processed food, there is a method for producing plum puree described in JP-A-9-85044. In this method, plum fruits are pulverized while adding a predetermined amount of sugar to plum fruits. As a result, plum puree, which can be a raw material for secondary processed foods with excellent taste, fragrance and color, can be produced efficiently in a short time.
JP-A-9-75044

  However, pulverization of ume fruit while adding saccharides is to obtain plum puree with no astringency, fragrance and good color tone, and although it can be produced efficiently in a short time, saccharides are already present. Since it is added, there is a problem that the application is limited.

  Moreover, in the case of removing the seeds, the ume fruit has a large proportion (30 to 40%) of the seeds and the seeds and the flesh are in close contact. As described in the publication, it must be pulverized with the pulp or removed manually. When the seeds are pulverized together with the pulp, the separation of the seeds is troublesome, and when the seeds are manually separated, they cannot be produced in large quantities.

  In addition, plums are densely packed on the surface, so bacteria are likely to adhere to them, and washing before processing is carefully performed. Many. Therefore, there is a limit to the processing amount of ume fruit, and it has been rarely used as a secondary processed food other than umeboshi and umeshu even though it has been popular for a long time. In addition, umeboshi often refrain from intake because salt is a major factor in hypertension.

  Therefore, the present invention has been made in order to solve such a problem, and it is possible to separate seeds and pulp by a simple manufacturing method, and an inexpensive method for producing a nut fruit paste and the seeds and paste used for the production. It aims at providing the separation apparatus with a pulp. In particular, an object of the present invention is to provide a method for producing a plum paste and a device for separating a paste pulp as a secondary processed food of plum which is popular as a health food.

  The present invention has the following configuration in order to achieve the above object. That is, in the method for producing a drupe paste according to the present invention, the drupe that has been pretreated to remove dust and the like is roasted as it is without adding water or oil, and then water is supplied when the epidermis collapses. The fruit pulp is boiled until it becomes pasty, and then the seed and pasty pulp are separated to obtain a fruit and fruit paste. When roasting drupes, it is preferable to roast on low heat. Here, to fry is to stir while heating only the nuts and fruits without adding water or oil as in the case of fried. Moreover, it is preferable to boil while removing acupuncture when boiling.

  The seed and paste pulp separation device used for the production of drupe paste comprises a vacuum pump with a suction pipe, a suction cylinder with a suction pipe, and a storage container, and suction of the suction pipe and suction cylinder of the vacuum pump. Each of the pipe ends is attached through a lid that seals the storage container, and the suction cylinder connects the suction pipe to the rear end face of the hollow body whose front end face is closed, and the peripheral surface and / or A large number of small holes are formed in the distal end surface.

  The suction pump is attached to the vacuum pump and the filtration container, and the suction pipe has a leading end penetrating a lid that seals the storage container. The bottom plate of the filtration container may be provided with a bottom plate having a large number of small holes, and the rear end side of the bottom plate may be narrowed to connect the suction pipe. Thus, in the configuration in which the suction pipe is directly connected to the filtration container, the opening of the filtration container may be a container that opens as it is, or a container that closes the opening when suctioning. May be. In the case of a container whose opening is closed at the time of suction, it is preferable to use a flexible bag-like container so that it can be deformed.

  As described above, according to the method for producing a drupe paste according to the present invention, the work is efficient and can be processed in a large amount. Moreover, since raw ume can be made into a paste as it is, without adding an additive, it can be seasoned freely and can be mixed with other foods, and the range of applications is expanded. Moreover, since salt is not used, there is no worry of hypertension and it can be ingested sufficiently as a health food. Furthermore, since the seeds are separated and removed, the capacity is reduced, and the seeds can be stored in a vinyl pack or the like by simple cold storage and freezing.

  Further, according to the separation apparatus for drupe paste according to the present invention, seeds and pulp can be separated very easily and efficiently, and at the same time, the separated paste can be stored in bottles or packs as they are. Can do. Moreover, since the structure is simple, it can be provided at low cost and anyone can use it easily.

Below, the manufacturing method of the drupe paste of this invention is demonstrated in detail about embodiment of a plum according to the flowchart shown in FIG.
<Pretreatment>
As pretreatment, harvested raw plum fruits are prepared, sorted and washed. Remove large scratches and debris, and wash as necessary. As with conventional sorting operations, careful handling is required, but since it is heat-treated and made into a paste, even if light scratches or deformed fruits are mixed, it does not matter much. Therefore, harvesting operations and sorting operations can be greatly shortened, and the efficiency of processing operations can be measured. In addition, the harvest time of plum fruit is limited and must be harvested in a short period of time, so it cannot always be processed into a paste at the same time as harvesting. Therefore, the pre-processed plum fruits may be kept cold and frozen (stored) as needed after the pre-treatment.

<Fry>
First, put the plums in a flat bottom pan, etc. In other words, put the raw plum fruit in a flat bottom pan and fry it over low heat. When fried, stir while heating only the plums without adding any water or oil. During heating, keep it roasted continuously to prevent scorching, and continue until the skin of the plum fruit breaks down. The reason for roasting is to make the epidermis into a paste when boiled, as will be described later. For example, in the case of 1 kg of plum fruit, the roasting may be continued for about 40 minutes so that the maximum temperature of the plum fruit is around 95 ° C. The standard time for roasting is to break down the plum skin.

<Simmer>
Stir while heating until the skin of the plums breaks down, then supply water to the flat bottom pan and continue heating. The amount of water supply should be about half of the plum fruit. This is because it takes time to boil down if there is too much water. Therefore, the amount of water is not particularly limited. When there is a lot of water, you can lengthen the boiling time.

  When water is added and heating is continued, the plum boil will come out gradually. Sequentially pick up the ak that came out. When simmering the acupuncture, the fruit of the plum collapses and the pulp turns into a paste, resulting in a so-called paste pulp with some seeds exposed from the pulp. In this way, when the pasty pulp is finished, turn off the heat and cool to room temperature.

<Separation of seeds and pulp>
When left for about 15 minutes, it cools down to room temperature, so the paste plum is separated into seeds and pulp. In order to separate into seeds and pulp, the pulp part of the paste plum may be sucked. A separating device may be used to suck the pulp portion. The separation device may be provided with a suction cylinder having a large number of small holes in its peripheral surface, and the suction cylinder may be placed in paste plum and suction extracted while stirring. If stirred, the surface of the seed is sucked while being rubbed, so that the paste-like pulp can be separated cleanly from the seed.

  Normally, the plum fruit is in close contact with the tissues around the seeds, and it is difficult to separate only the flesh, but by boiling it into a paste, it is in a state that can be easily separated, Only a portion of the paste pulp can be sucked and separated by the separation device. The separation device may be sucked through a suction pipe having a suction tube with a small hole attached to the tip so as to suck only the pulp. If the suction cylinder is put into a flat pan and sucked while stirring, the seeds and the pulp can be easily separated.

<Save>
The paste-like pulp separated by sucking may be stored as it is, but it is desirable to sterilize by heating because some miscellaneous bacteria may be mixed during the separation operation. The heat sterilization may be slightly boiled. For example, in the case of a paste-like pulp extracted from 1 kg of raw plums, it may be boiled for about 10 minutes while heating around 95 ° C. Then, transfer to a container, seal and store. When storing, the seeds have been removed, so it becomes compact, and it can be stored in a bottle or a plastic pack or the like and kept cold or frozen.

  In addition, when using the separated paste as a raw material for secondary processed foods such as jam, it may be adjusted by immediately adding sugars or seasonings.

  Next, a separation device that separates seed and pulp parts from paste plum will be described. FIG. 2 shows a first embodiment of the separation device, and the separation device 10 includes a vacuum pump 11, a storage container 12, and a suction cylinder 13. A suction pipe 15 is connected to the vacuum pump 11, a suction pipe 16 is connected to the suction cylinder 13, and the tips of the suction pipes 15, 16 penetrate the sealing lid 17 of the storage container 12. Attached. Accordingly, the suction pipe 15 and the suction pipe 16 are open in the storage container 12 and communicate with each other via the storage container 12.

  As is apparent from the drawing, the suction cylinder 13 is a cylindrical hollow body having a closed front end surface, the rear end surface is connected to the suction pipe 16, and a large number of small holes 14 are formed on the peripheral surface and the front end surface. It has been drilled. The size of the small holes is preferably as small as possible if the plum paste can be sucked, and can be set to 0.5 to 3 mm. The suction tube 13 is not limited to a cylindrical body, and can have an arbitrary cross-sectional shape such as an ellipse, a triangle, or a rectangle.

  In order to suck the paste portion using the separator 10, the vacuum pump 11 is operated and the suction cylinder 13 is placed in the paste plum 19 in the pan 18. When the suction cylinder 13 is inserted, it is sucked from the small hole 14. When the vacuum pump 11 is operated, the inside of the storage container 12 is depressurized, so the paste pulp of the paste plum 19 is sucked from the small hole 14 and filled into the storage container 12. Since the entire paste pulp cannot be sucked with the suction cylinder 13 put in, it is moved while stirring. When the suction cylinder 13 is moved while stirring, the surface of the seed is rubbed, so that the seed and the paste pulp can be separated efficiently, and are separated cleanly from the surface of the seed.

  FIG. 3 shows a second embodiment of the separation device, and the separation device 20 includes a vacuum pump 11, a storage container 12, and a filtration container 21 whose upper surface is open. The storage pipe 12, the suction pipe 15 connected to the vacuum pump 11, and the suction pipe 16 connected to the filtration container 21 are the same as in the first embodiment, and the combination thereof is also the same. Reference numerals are assigned and explanations thereof are omitted.

  The filtration container 21 is a funnel-shaped body having an upper surface opened and a lower end surface narrowed. A bottom plate 23 having a small hole 22 is provided inside the lower end, and the bottom plate 23 and the lower end surface are provided with each other. A substantially conical gap 24 is formed between them. A suction pipe 16 is connected to the center of the lower end surface of the filtration container 21.

    In order to suck the paste pulp using the suction device 20, first, the paste plum 19 boiled in the filtration container 21 is put, and the vacuum pump 11 is operated. When the vacuum pump 11 is activated, the bottom plate 23 is in a hermetically sealed state, so the inside of the storage container 12 is decompressed, and the paste pulp of the paste plum 19 is sucked from the small hole 22 and filled into the storage container 12. . If there is a possibility that the small holes will be clogged with the paste pulp only by suction, it is preferable to create a gap while stirring. By suctioning with stirring, only the pasty pulp portion is sucked and can be separated cleanly from the seed surface.

  The filtration container 21 is not shown in the figure, but may be a container that can be sealed by closing the opening without opening the upper surface. By sealing the opening, the paste pulp can be sucked from the small hole 22 with a small suction force. In the case of a container that can be sealed, it is preferable to use a bag-like container that can be gradually deformed by suction to reduce the volume.
