Abstract

PURPOSE:A grated Japanese radish food having fresh flavor and sharp taste even after long-term preservation, containing a mustard oil. CONSTITUTION:A raw Japanese radish is washed, optionally peeled, grated by a grating metallic tool, etc. to give grated Japanese radish, which is light squeezed with a dishcloth to regulate a water content, and blended with 20-500ppm mustard oil which is a volatile oil containing an isothiocyanic ester as a sharp taste component, and, if necessary, grated horse radish and gum such as xanthan gum, etc., to give the titled food. When long-term preservation is aimed, the food is put in a freeze-resistant container (e.g., plastic bag), frozen at -20 deg.C, to give a frozen food.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a novel grated radish food.

[Prior Art] Grated radish has been widely used in ordinary households since ancient times, as an accompaniment to dishes such as fried and grilled fish, and as a condiment to dishes such as hot pot dishes. This grated radish not only loses its freshness over time, but also the vitamin C contained in the radish decomposes and the various effects that it can originally exert diminish, so it cannot be eaten. Each time, I used only the required amount.

Under these circumstances, frozen grated radish has been proposed as a grated radish that can be stored for a long period of time and is suitable for mass production (Japanese Patent Laid-Open Publication No. 11158/1983). This publication also proposes adding a sour component to grated daikon radish before freezing in order to enhance the preservation effect or to reduce the spiciness.

[Problem that the invention seeks to solve]

゛ However, even if the frozen grated radish mentioned above is frozen freshly grated radish, the flavor (flavor) and taste (spicy) of the freshly grated radish after thawing will be lost. It was as if it had almost disappeared.

Therefore, it is an object of the present invention to provide a grated radish food that can be enjoyed as freshly grated when used, even when frozen.

[Means for solving problems]

The present inventor conducted extensive research in accordance with the above objectives, and discovered that grated radish obtained by blending mustard oil with grated raw radish is suitable for the above objectives. Ta.

The present invention was completed based on the above findings, and provides a grated radish food characterized by containing mustard oil.

In the present invention, "mustard oil" refers to a volatile oil containing isothiocyanic acid ester as a pungent component, which is obtained by pressing mustard, fermenting the residue separated from fatty oil, and then steam distilling it.

The content of mustard oil in grated radish is difficult to determine as it varies depending on the type of radish used as raw material, harvest time, etc., but it is generally 20 to 500 pp.
About m is sufficient. When the content is less than 20 ppm, the grated radish food suitable for the purpose of the present invention has mu<, and 500 ppm.
This is because if the amount is more than m, the spiciness derived from mustard oil will be felt strongly. Especially, 150~3oo
It can be said that approximately ppm is preferable.

Such grated radish food of the present invention is generally prepared as follows. J is built.

After washing raw daikon radish, peeling it if necessary, and grating it with a grater, or passing it through a chopper and crushing it with a mixer, etc., if the grated radish has a high moisture content. Place on a strainer and let the water drain naturally, or lightly wring it out with a dish towel to adjust the amount of water. This moisture adjustment is particularly preferable when the final product is in the form of frozen grated daikon radish. Normally, if the moisture content is too high, the texture is likely to be destroyed by freezing, and the thawed product will have a lot of syneresis, resulting in a rough or grainy texture. It can be prevented.

Next, a predetermined amount of mustard oil is added to the grated radish thus obtained, and the mixture is thoroughly mixed to obtain a grated radish food according to a conventional method.

In addition, when blending mustard oil, as long as it does not impair the blending effect of this mustard oil in the final product, for example, when grated horseradish is used to improve the taste, or when frozen, it may be used to prevent syneresis during thawing. Therefore, gums such as xanthan gum may be added.

When the grated radish food of the present invention is intended for long-term storage, it is stored in a freeze-resistant container, such as a plastic bag, and then frozen according to a conventional method, generally at around 1920°C. In addition, if long-term storage is not desired, the product may be kept in the palm-knit form as a room-temperature product, or it may be refrigerated in the form of a chilled product.

(Function) The mustard oil contained in the grated radish food of the present invention is considered to be involved in some way in retaining the flavor and taste of freshly grated radish, thereby acting effectively.

〔effect〕

As is clear from the results of the test examples below, the grated radish food of the present invention has an almost freshly grated flavor (aroma) even when frozen for long-term storage.
It is a grated daikon radish food with a pleasant taste (spiciness). In addition, regardless of the length of the storage period, we can always provide grated radish of a constant quality upon thawing.Furthermore, by appropriately changing the blending ratio of mustard oil, we can use daikon radish as raw material, whose taste can change depending on the type or harvest time. However, it also has the advantage of being able to provide grated radish of almost constant quality.

Test Example (I) Production of frozen grated radish: Fresh radish (two-year old, harvested in squares) was removed from the washing machine, passed through a chopper (diameter: 3 mm), and then crushed with a mixer to produce grated radish. Then, put it on a strainer and let it drain naturally.

Add mustard oil to the grated radish obtained in this way at 0.10.20.50.100°150.200.3
Mix 00, 400, 500 and 'CF6ooppm in varying proportions, mix thoroughly, and then separately store each bag in a polyethylene bag (100 g).After sealing, freeze at -18℃ and leave as is. A total of 111 types of frozen grated radish foods were manufactured after storage for a week.

(It) Sensory test and results: Each frozen grated radish food was thawed on the first week of storage, and its flavor and spiciness were determined based on freshly grated raw radish (same type and harvested at the same time). Based on the scoring method by panel members (10 people) who have been trained in the selection process, ?PII
Ilishita. The results expressed as the average scores of the 10 participants are shown in the table below.

Table notes 1. The scoring method was a 5-point system in which each point had the following meaning.

5... Aroma and spiciness of freshly grated daikon radish 4... Aroma and spiciness quite similar to freshly grated radish 3... Freshness of freshly grated radish can be felt to some extent 2... Grated radish The freshness of the freshly grated meat is only slightly noticeable1. *I could feel the aroma of freshly grated daikon radish, but the spiciness from the master oil was strong.

〔Example〕

Hereinafter, the present invention will be explained in more detail with reference to Examples.

1 Kodanyu grated daikon radish obtained according to the method of the above test example,
Frozen grated radish food (mustard oil 200p
pm-containing) was produced.

Example 2 1 serving of grated radish obtained in the same manner as in the test example described above, except that instead of using a strainer to drain the water, the water was wrung out lightly with a cloth to adjust the water content! 9, mustard oil 29 and 10g of grated horseradish
After mixing thoroughly, prepare frozen grated radish food (mustard oil 150pp) in the same manner as in the above test example.
Example 3 Grated daikon radish obtained according to the method of the above test example 10 to 9,
After blending 3 g of mustard oil and 209 xanthan gum and thoroughly mixing them, a frozen grated radish food (containing 250 ppm of mustard oil) was produced in the same manner as in the above test example.

When the frozen grated radish food prepared by +5t in Examples 1 to 3 was thawed on the first week of storage, it had a fresh taste that was almost the same as freshly grated radish in terms of flavor and taste. .
