Problems solved by technology

[0003] The purpose of the present invention is to provide a storage method for silkworm cocoons, which solves the problem of denaturation of the outer layer sericin protein of the cocoon silk due to high temperature in the traditional storage method of silkworm cocoons, which leads to a decrease in the unwinding rate during the silk reeling process and directly affects Raw silk production problem

Embodiment 1

[0013] A method for storing silkworm cocoons, comprising the following steps:

[0014] A. Clean the fresh cocoons and remove the dead or diseased cocoons;

[0015] B. Slowly cool the fresh cocoons obtained in step A to the temperature in the cold storage at a rate of 0.5° C. / 10 min in advance, and then put the fresh cocoons through the cooling treatment into the cold storage for refrigeration. The temperature of the cold storage is kept at 6°C, humidity kept at 80%;

[0016] Among them, the above-mentioned cold storage is ventilated every one month.

Embodiment 2

[0018] A method for storing silkworm cocoons, comprising the following steps:

[0019] A. Clean the fresh cocoons and remove the dead or diseased cocoons;

[0020] B. Slowly cool the fresh cocoons obtained in step A to a temperature close to the temperature in the cold storage in advance at a rate of 1° C. / 10 min, and then put the fresh cocoons through the cooling treatment into the cold storage for refrigeration. The temperature of the cold storage is kept at 8°C, humidity kept at 70%;

[0021] Among them, the above-mentioned cold storage is ventilated every 2 months.

Embodiment 3

[0023] A method for storing silkworm cocoons, comprising the following steps:

[0024] A. Clean the fresh cocoons and remove the dead or diseased cocoons;

[0025] B. Slowly cool the fresh cocoons obtained in step A to a temperature close to the temperature in the cold storage in advance at a rate of 2° C. / 10 min, and then put the fresh cocoons through the cooling treatment into the cold storage for refrigeration. The temperature of the cold storage is kept at 4°C, humidity kept at 75%;

[0026] Among them, the above-mentioned cold storage is ventilated every one month.

Abstract

The invention discloses a storage method of a silkworm cocoon. The method comprises the steps of slowly cooling and freezing fresh cocoons to a temperature which is close to the temperature in a refrigerator in advance, and then storing the cocoons in the refrigerator. By adopting the storage method, the cocoon does not need to be dried at the high temperature, the silkworm cocoon pupae is prevented from being broken, the completeness of the silkworm cocoon is maintained, sericin on the outer layer of the silkworm cocoon is not denatured, and the yield of raw silk is not affected.

Description

technical field [0001] The invention belongs to the technical field of silkworm cocoon reeling industry, and in particular relates to a method for storing silkworm cocoons. Background technique [0002] Because silkworm breeding is highly seasonal, the silkworm cocoons collected must be stored in order to provide long-term raw material silkworm cocoons for the silk reeling industry. The traditional cocoon storage method adopts the dry cocoon storage method, which is to kill the collected cocoons at high temperature and dry the live pupae in the cocoons to achieve the purpose of long-term preservation of the cocoons. However, there are big problems in this traditional cocoon storage method. For example, due to the use of high-temperature baking, while the live pupae in the cocoon are killed and dried, the outer sericin protein of the cocoon silk will also be damaged by the high temperature. And produce denaturation, thereby cause the unwinding rate to drop in the silk reelin...
