Embodiment 1

[0028] Example 1 The Effect of Pupation Degree on Healthy Pupal Rate

[0029] Use the following steps to investigate the effect of the degree of pupation of fresh cocoons on the rate of healthy pupae

[0030] S1. Collect fresh cocoons, stack them in the cocoon station according to the rack insertion method, the thickness of the cocoons is recommended to be 10cm, and place them until pupation, and then place them for the time recorded in Table 1 after pupation;

[0031] S2. Pack the fresh cocoons treated in S1. into baskets, about 8.5kg of fresh cocoons per basket, and carry out refrigeration treatment. days; and check the healthy pupa rate by sampling;

[0032] Table 1

[0033] .

[0034] It can be seen from Table 1 that under the condition of temperature of -5-0°C and relative humidity of 70%, as the storage time prolongs, the healthy pupae rate of pupation for 1-2 days is the lowest, the main reason may be that the pupae skin is too Tender and easily damaged during ha...

Embodiment 2

[0036] Example 2 Effect of cold storage temperature on healthy pupae rate

[0037] Use the following steps to investigate the effect of cold storage temperature on the rate of healthy pupae

[0038] S1. Collect fresh cocoons, stack them in the cocoon station according to the rack insertion method, the thickness of the cocoons is recommended to be 10cm, and place them until pupation for 5-6 days;

[0039] S2. Pack the fresh cocoons treated in S1 into baskets, about 8.5kg of fresh cocoons per basket, and carry out refrigeration treatment. The temperature of refrigeration treatment is as recorded in Table 2. The relative humidity of refrigeration treatment is 70%, and it is refrigerated for 90 days ; And check the healthy pupa rate by sampling;

[0040] Table 2

[0041] .

[0042] It can be seen from Table 2 that under the condition of temperature between -5 and 0°C, refrigerated for 90 days, the healthy pupae rate is high, if the temperature is too low, some silkworm pupa...

Embodiment 3

[0043] Example 3 Effect of Humidity in Refrigeration on Healthy Pupae Rate

[0044] Use the following steps to investigate the effect of refrigerated relative humidity on the rate of healthy pupae

[0045] S1. Collect fresh cocoons, stack them in the cocoon station according to the rack insertion method, the thickness of the cocoons is recommended to be 10cm, and place them until pupation for 5-6 days;

[0046] S2. Pack the fresh cocoons treated in S1 into baskets, about 8.5kg of fresh cocoons per basket, and carry out refrigeration treatment. The temperature of refrigeration treatment is -5-0°C, and the relative humidity of refrigeration treatment is recorded in Table 3. 90 days; and check the healthy pupa rate by sampling;

[0047] table 3

[0048] .

[0049] It can be seen from Table 3 that at a temperature of -5 to 0°C, the relative humidity is too low, and the healthy pupae rate decreases, and the relative humidity is too high, and the cocoon shell will rot. Consi...

Abstract

The invention discloses a comprehensive utilization method of fresh cocoons of silkworms. The method includes the steps of S1, collecting fresh cocoons and storing till pupation occurs; after pupation, placing pupas for 5-6 days; S2, loading the fresh cocoons treated in the step 1, with baskets, cold-preserving the cocoons at the temperature of -5-0 DEG C, under the relative humidity of 60-70%, for 30-90 days; S3, cooking the fresh cocoons, treated in the step 2, by the vacuum penetration sol segregation technique, and reeling silk to obtain raw silk and fresh pupas. By the comprehensive utilization method, fresh pupas of the silkworms can be stored in a long period of time without killing the pupas; silk reeling is performed on the fresh pupas stored by the method to obtain a great amount of fresh pupas; accordingly, high-quality silk can be obtained through the application of silk reeling in fresh cocoons, fresh pupas of high economic value can be obtained, and the method is of great practical significance to post-processing of silkworms.

Description

technical field [0001] The invention belongs to the field of silkworm breeding and utilization, and in particular relates to a method for comprehensive utilization of silkworm cocoons. Background technique [0002] The silkworm, or silkworm, is a silk-spinning insect with high economic value. Its cocoon can be reeled. The silk of the silkworm is a precious textile raw material, which is mainly used for weaving silk. Silkworm chrysalis contains 60% crude protein, 30% crude fat, 3%-4% chitin, 5% sugar (by dry mass) and other active substances, such as antimicrobial peptides, lysozyme, hormones, trace elements , vitamins, etc. Silkworm chrysalis protein contains 20 kinds of amino acids, of which the essential amino acids for human body account for more than 40% of the total amino acids; the fat of silkworm chrysalis contains a variety of unsaturated fatty acids necessary for human body, such as oleic acid, linoleic acid and linolenic acid, among which unsaturated The fatty a...
