Storage fresh-keeping method for fresh cocoon of cultivated silkworm

Abstract

The invention provides a storage fresh-keeping method for a silkworm fresh cocoon; silkworm chrysalis inside the fresh cocoons are killed by the quick freezing of dry ices; the fresh cocoons with the chrysalis killed are arranged in a closed article where the air is pumped out and the dry ices are added and the dry ices are converted into the CO2 gas under normal temperature; the fresh cocoons are hermetically stored under the anaerobic condition. The storage fresh-keeping method can keep the natural state of the cocoons better, has little effect on the silk quality, has simple, sanitary and convenient operation, quick disposal speed and low processing cost, can improve the silk generation rate and the silk generation quality; after reeling silk, the fresh cocoons can be taken as the raw material of the deep processing and is suitable for popularization and application in large scale.

Description

technical field

[0001] The invention relates to a processing technology for silkworm fresh cocoons, in particular to a storage and preservation method for storing silkworm fresh cocoons at room temperature by using carbon dioxide gas after killing pupae with dry ice. Background technique

[0002] After the fresh cocoons of silkworms (including castor silkworms and tussah silkworms, etc.) are purchased, they are generally baked into dry cocoons in a coal stove, and stored in a cocoon warehouse at room temperature for cocoon cooking, silk reeling and silkworm chrysalis processing. This is a traditional craft for decades. technical route. The process of baking silkworm cocoons and silkworm chrysalis at 105-110°C for 6-8 hours will cause the denaturation of cocoon sericin protein and silkworm chrysalis protein. Fatty acids such as chrysalis oil will become rancid due to oxidation, resulting in foreign matter, which will affect further processing. Fresh cocoons are baked at high...
