JPS6098940A - Freezing of separated fish roe for seasoning and processing - Google Patents

Abstract

PURPOSE:To prevent the collapse of separated fish roe in a container caused by the transport of the container, by filling the separated fish roe in a container leaving a space larger than the freeze expansion volume of the roe, and filling the space with an elastic filler. CONSTITUTION:The separated fish roe (b) is filled in a container (a) leaving a space (c) larger than the sum of the seasoning liquid container and the volume expansion of the roe caused by freezing. The top of the roe is if necessary covered with a water-impermeable film 3 such as cellophane film, and a container (d) of a seasoning liquid is placed thereupon. The space (c) which will be left after fitting the lid 2 to the container (a) is filled with a soft elastic filler (e), and the container is closed with the lid. The unnecessary movement of the separated fish roe (b) in the container (a) during the transport of the container can be prevented by this procedure.

Description

[Detailed Description of the Invention] Sprung fish eggs of salmon, trout, etc. that have been pretreated with water, etc. and seasoned, and then stored frozen are expanded during freezing due to absorbed water and other factors, and are therefore edible. Sometimes, when thawed, the egg membrane ruptures or cracks, causing the contents to flow out and crush the egg grains, significantly reducing their commercial value.

In order to solve this problem, the applicant removed the fish body and separated the sprayed fish eggs into 71 pieces, without washing or seasoning them, which would cause them to absorb moisture, and in addition, placed them in the required container. A method (Japanese Patent No. 1,136,112) of storing and freezing the sprayed fish eggs while leaving a void with a capacity corresponding to at least the expansion volume due to freezing was provided.

However, even in this method, as mentioned above, there is a void in the container with a volume equivalent to at least the expansion volume of the spray eggs due to freezing, so each time the container is moved or vibrated before freezing, the stored powder The disadvantage is that the roe moves within the container, which causes the roe to collapse.

The present invention was proposed with the aim of eliminating this drawback, and its emphasis is on filling the above-mentioned void with an elastic body such as a sponge.

That is, the present invention stores the scattering eggs in a container while leaving a gap exceeding the volume corresponding to the expansion volume of the scattering eggs due to freezing, and fills the gap with an elastic body such as a sponge. , to prevent the spray eggs from collapsing due to movement or vibration of the container before freezing, and to prevent the expansion of the spray eggs due to contraction of the elastic body as the spray eggs expand due to freezing. This is to ensure that there are no errors.

Examples will be described below with reference to the drawings.

The container a shown in FIG. 1 consists of a rectangular main body 1 made of synthetic resin such as polystyrene or styrene, and a lid 2 that fits tightly into the rectangular main body 1.

b is a scattered fish egg, for example, each fish egg is separated and collected from the ovary taken out from the body of a fish such as salmon or trout using a known method. This sprinkling fish roe can be left as is without any processing such as washing or seasoning that would cause it to absorb moisture.
That is, a predetermined amount of the dispersed fish eggs are stored in the main body 1 of the container a while keeping the moisture content equivalent to that at the time of egg collection.

The storage capacity of the sprayed fish roe is set so that a predetermined volume of void C remains, taking into account the volume of the roe expanded by freezing and the volume of the seasoning liquid container described later.

According to experiments, the specific expansion rate of salmon, trout, and other spray fish eggs when frozen at -15 to -25°C is 2 to 2.
It has been confirmed that it is about 3%. d is soy sauce,
It is a bag-shaped container filled with a seasoning solution made of chemical seasonings, etc., and is made of a known waterproof material.

In the above, the sprinkling fish roe is placed in the main body 1 by approximately 70 to 70% of its volume.
Fill it to about 80%, cover the top with a water-impermeable film 3 such as cellophane as necessary, and place the seasoning liquid on top of the container.
Put on.

Then, a gap C is generated when the lid body 2 is tightly fitted into the main body 1.
A flexible elastic body e such as a synthetic resin sponge is loaded into the container and the lid is closed. Thereby, even if the container a is moved, the scattering fish eggs will not move unintentionally within the container a.

Then, it is frozen at -15 to -25°C, and as the aerated fish eggs expand during this freezing, the elastic body e contracts, so there is no risk of adversely affecting the expansion.

To make the frozen sprung fish roe edible,
Open the lid and take out the elastic body e and seasoning liquid container d, and thaw at room temperature.

Pour in the seasoning liquid from thawing and opening liquid, stir in the sprinkling fish eggs, and season. In this case, there are 7 eggs in the main body 1.
Since the content is only about 0 to 80%, operations such as stirring can be carried out appropriately without causing the fish eggs to scatter outward.

In addition, each company's thawed sprayer eggs do not contain treated water and have an inherent expansion rate of only 2 to 3%, so the egg membranes will not be torn and the expansion will not occur. Because it does not come into contact with the hard inner surface of the container, it does not collapse, and each company retains its original spherical shape.

Container a'' in FIG. 2 is similar to container a in FIG. The only difference is that there is no other change in the circumstances of implementing the present invention.

In FIG. 2, b' is a spray egg, Co is a void, do is a seasoning liquid container, and 3' is cellophane. ``Since it is sufficient to substantially load the elastic body into the gap C or Co, it is loaded separately before closing the lid as in the case of Fig. 1,
Alternatively, instead of attaching it to the back of the lid 2' and removing or loading it at the same time as the lid 2' is opened and closed, as shown in Figure 2, You can stay there.

Further, the seasoning liquid container is not limited to a bag shape, but may be a bottle shape or a tube shape.

As is clear from the above, according to the method of the present invention, an elastic body such as a sponge is loaded into the cavity of a container containing spray eggs, so the container is moved or vibrated before freezing. Even if something happens, the stored spray eggs will not collapse, and the elastic body will not interfere with the inherent expansion of the spray eggs when frozen.
