Abstract

PURPOSE:To enable the long-term preservation of grated radish in a fresh state, by putting the fresh grated radish in a gas impermeable bag, sealing it hermetically, preserving it in a frozen state. CONSTITUTION:Fresh grated radish is put in a gas impermeable gas coated with a halogen-containing resin, sealed hermetically in a vacuum state, in an inert gas, or together with air. There is no restriction for conditions of preservation in a frozen state, but preservation at about -20 deg.C is most preferable with respect to effect. Consequently, grated radish can be preserved for a long period in a fresh state.

Description

【発明の詳細な説明】 この発明はおろし大根長期保存法に関するものである。[Detailed description of the invention] This invention relates to a long-term preservation method for grated radish.

一般−こ、おろし大根は、天ぷら、湯豆腐、焼鳥勢のた

General - Grated radish is widely used as a kind of seasoning added to tempura, boiled tofu, and yakitori sauce.

This is thought to be due to the good harmony between soy sauce and grated radish.However, grated radish like this is complicated to grate, and especially when used for food and drink, it is difficult to grate it beforehand. However, in many cases, grated radish has the best flavor when it is freshly grated, and its flavor rapidly deteriorates over time. drop down. Therefore, at present, grated daikon radish is simply added to dishes to give it a nice shape. Therefore, the inventor wondered if there was a way to preserve grated daikon radish, which rapidly loses flavor and is extremely difficult to preserve in its fresh state. I packed it in a plastic film bag and stored it in the freezer. However, even when stored in this manner, the flavor deteriorated and the grated bonito radish turned brown.

Therefore, the inventor conducted six additional experiments by changing the material of the bag and filling it with inert gas or not filling it with inert gas. As a result, when freshly grated radish is stored frozen in a gas-impermeable bag,
It was discovered that grated daikon radish can be stored in a fresh state with almost no deterioration in flavor, and can be stored for a long period of time, and this invention has been constructed.

That is, the gist of this method is to put fresh grated radish in a bag impermeable to scum, seal it, and freeze and preserve it in that state.

In this way, when grated daikon radish is frozen and stored in a gas-impermeable bag, the grated radish can be stored in a fresh state without browning for a long period of time, especially for a long period of 3 months or more. This is thought to be due to the following reasons.

In other words, the gas-impermeable bag prevents oxygen from entering from outside S air, prevents deterioration of flavor components caused by tR element, and prevents browning caused by the enzyme polyphenol oxidase by blocking oxygen. Possible-1
In particular, it is preferable to use a gas-impermeable bag coated with a halogen-containing resin such as vinylidene chloride resin 24, or one made of a halogen-containing resin, from the viewpoint of effectiveness.

This type of resin has a small amount of free hydrogen halide (1-ici in the case of vinylidene chloride resin), which, together with the oxygen blocking effect, deactivates the enzyme polyphenol oxidase, resulting in sterilization. It is thought that because it also exerts its effects, the browning phenomenon is extremely effectively prevented, and the deterioration of flavor is also prevented.

When putting fresh grated daikon radish into a gas-impermeable bag and sealing it, it can be vacuum-sealed, it can be sealed with an inert gas such as N2 gas, or it can be sealed with air. good. As described above, according to the method of the present invention, even if the grated radish is sealed together with air without any special treatment such as vacuum sealing, the same effect as a vacuum seal ring can be obtained.

As raw radish for grated radish, each stalk of radish can be opened, and the type thereof is not limited in any way. In addition, the method of grating is also free. In this case, vegetables from the pond, such as carrots, may be grated along with the radish. Therefore, the grated radish referred to in this invention is limited due to the conditions of frozen storage where the raw material includes not only daikon radish but also grated radish and other vegetables, such as grated momiji. It's not a thing.

(Left below) From the table above,
It can be seen that in Examples 1 to 3, the preserved grated daikon radish retains the fresh flavor of freshly grated radish even after preservation for one week or even for three months. What should be noted here is that grated daikon radish packed directly into a sealed package also has N2
This is as effective as encapsulation or vacuum sealing, and according to this invention, grated radish can be stored in a fresh state for a long period of time without complicated treatments such as N2 encapsulation or vacuum sealing. It is.

As described above, according to the present invention, freshly grated radish is placed in a gas-impermeable bag and sealed, and then frozen and stored in that state, so that the grated radish remains freshly grated. It can be stored for a long time. Therefore, by supplying this in bags for each single use, restaurants can always have fresh grated radish to accompany their dishes, which can greatly contribute to improving the flavor of the dishes. become. In particular, the above effects can be achieved by coating a halogen-containing resin as a gas-impermeable body.
Alternatively, if a resin containing halogen is used, the problem becomes even more noticeable.
