Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to sweet chestnuts having an incision in the pericarp and foods that can be easily consumed using these sweet chestnuts.

[0002]

[Problems to be solved by conventional techniques and devices]

 Sweet chestnut is also called roasted chestnut, and its unique texture and flavor are favored. It is used not only as a snack but also as an ingredient in dishes such as chestnut rice.

[0003] Since these sweet chestnuts are usually obtained by directly baking raw chestnuts with relatively hard skin (onion skin), when eating sweet chestnut fruits (fruit), the peels are removed. It needed to be stripped.

However, when the peeling is performed by hand, a relatively large force is required to push a human nail against the peel to press and cleave a part of the peel, and it is necessary to use a relatively large force. The trick was necessary. Moreover, even if the procedure for peeling the skin is obtained, if a certain number of peels are peeled off, an excessive load is applied to the nails, which may cause inconveniences such as injury to the nails.

[0005] In order to facilitate the peeling operation of the peel, various tools and instruments called peelers and splitters have been proposed so far. It was only a tool for making crevices and a substitute for human nails. Therefore, even if the skin is cracked or split with these tools, to completely peel the peel of the sweet chestnut, it is necessary to hold the body of the sweet chestnut from both ends in the longitudinal direction of these cracks and tears while holding the body of the sweet chestnut. Relatively labor-intensive work, such as pushing the cracks and rifts even larger, was still needed.

[0006] Thus, there is a long-awaited need in the art for a means for easily peeling the skin without losing the flavor and taste of the sweet chestnut.

[0007]

[Means for Solving the Problems]

 The present inventor completed the present invention in view of the above-mentioned problems in the prior art, and the gist of the present invention is that sweet chestnuts having an incision in the pericarp and foods using these sweet chestnuts are provided. is there.

[0008] The sweet chestnut of the present invention is generally easy to peel off the peel. In particular, if the sweet chestnut of the present invention is cooked, the sweet chestnut expands as the whole and the pericarp swells and becomes flexible, so that the peel can be easily and reliably peeled off without applying extra force to the pericarp. It becomes possible.

[0009] In addition, the sweet chestnut of the present invention has both the original flavor and taste of chestnut immediately before eating, that is, until cooking and heating to peel the peel, since the sweet chestnut peel and fruit coexist. You can appreciate it.

[0010]

[Embodiment of the invention]

 Hereinafter, the sweet chestnut of the present invention will be described in detail along with a production example.

First, raw chestnuts, which are raw materials, are washed with water, and those from which scratches and worms are conspicuous are removed. Next, the obtained raw chestnuts are applied to a specific gravity sorter, where chestnuts having the same weight are selected. Then, the chestnuts obtained by the specific gravity selection are introduced into a high-pressure roaster and subjected to a high-pressure roasting process, whereby sweet chestnuts (baked chestnuts) are obtained.

[0012] The peel of the sweet chestnut thus obtained is cut. This incision refers to making a cut, split or rip in the pericarp, and the position and size of the incision are not particularly limited. Preferably, referring to FIG. The incision 2 is provided by incising the pericarp with the blade A over a suitable length in the direction, that is, in the direction of the long axis of the skin of the sweet chestnut 1 in cross-sectional view. This incision may be performed by an automatic incision method in which the sweet chestnut is automatically fed to the blade A which is mechanically driven, in addition to the manual operation as described above.

In performing this incision, it is important to incise the pericarp of the sweet chestnut while taking care not to hit the knife A as much as possible, so as not to impair the commercial value of the sweet chestnut.

Next, the sweet chestnut of the present invention having the cut skin is processed into a commercial form. In other words, the sweet chestnut of the present invention is frozen and sorted, and a predetermined amount of the sorted sweet chestnut is stored and sealed in an appropriate container to obtain frozen sweet chestnut. Alternatively, the sweet chestnut of the present invention can be made into a retort sweet chestnut by further introducing a retort sterilization step after the freezing and sorting steps.

[0015] As a container for these frozen sweet chestnuts or retort sweet chestnuts, any container can be used as long as it is made of a material that is impermeable to water and that can be sealed. For example, referring to FIG. The sweet chestnut 1 can be stored in a simple plastic bag 3 to make the product 4. Alternatively, a sheet in which at least one surface of a paper sheet is subjected to waterproof processing in a bag shape or a container shape can also be used as the container. In addition, the sweet chestnut of the present invention can be stored in a storage container such as a can or a glass bottle.

In addition, food additives such as antioxidants, sweeteners, and preservatives can be optionally added to the bag 3 in order to enhance the preservability and palatability of the final product.

In the frozen sweet chestnut of the present invention, since the incised portion 2 is provided in advance, the frozen peeled sweet chestnut is naturally thawed, and the skin is easily peeled off by applying force to spread the incised portion 2 with a nail. Can be Alternatively, if the frozen chestnuts are cooked in a microwave oven or an oven toaster, instead of natural thawing, the heat spreads throughout the sweet chestnut 1, and as shown in Fig. 3, the whole sweet chestnut expands and the pericarp also swells. Since the incision 2 is also flexible, peeling of the pericarp can be performed easily and reliably. In addition, when cooked, the fruit 5 of the sweet chestnut 1 is exposed more and the fruit 5 is cooked moderately, so that not only the appetite is stimulated but also the taste of the chestnut is enhanced. In addition, in the frozen sweet chestnut of the present invention, since the peel and fruit of the sweet chestnut coexist immediately before eating, the flavor derived from the peel can also be enjoyed at the time of eating.

Similarly, since the retort sweet chestnut of the present invention is also provided with the incision 2 in advance, the peel can be easily peeled without cooking without being cooked. In addition, if the retort sweet chestnut is cooked in a microwave oven or an oven toaster, it is easy to peel the skin from the incision 2 for the same reason as described for the frozen sweet chestnut. 5 and perfume-derived flavor.

【Example】

 Hereinafter, embodiments of the present invention will be described. However, it should be understood that the present invention should not be construed as being limited by the disclosure of these embodiments.

The raw chestnut as a raw material was washed with water, and the chestnut selected by a specific gravity sorter was introduced into a high-pressure roaster and subjected to high-pressure roasting to obtain sweet chestnut. An incision was made in this sweet chestnut peel by hand using a knife, taking care not to damage it.

The sweet chestnuts thus obtained were frozen, and the ones tightly housed in plastic bags at a rate of 6 pieces / bag were made into frozen sweet chestnuts. The bag was opened, heated for 1 minute in a microwave oven, and tasted. The incision was widened, the fruit was exposed, and peeling was easy. In addition, the fruits were cooked moderately, and the flavor derived from the pericarp remained.

[0022]

[Effect of the invention]

 As explained above, according to the present invention, a new sweet chestnut that can easily and reliably peel the peel without the need to apply excessive force to the peel of the sweet chestnut, which was the intended purpose, has been realized. Is done. In addition, since the peel and fruit of the sweet chestnut coexist until the time of eating when the peel is peeled off, both the original flavor and taste of the chestnut can be appreciated.
