Storage method of fresh silkworm chrysalis

Abstract

The invention discloses a storage method of fresh silkworm chrysalis. The storage method comprises the following steps: (1) manually selecting clean fresh silkworm chrysalis; (2) soaking the selectedfresh silkworm chrysalis in a soaking liquid for 10-15 minutes and then taking out, and naturally airing, wherein the soaking liquid comprises the following raw materials in parts by weight: 1-5 partsof citric acid, 0.5-2 parts of konjac glucomannan, 1-5 parts of potassium hydrogen tartrate, 0.2-1 part of tea polyphenol, 8-15 parts of clove extracting liquid, 5-10 parts of Peppermint extracting liquid, and 20-30 parts of water; (3) transferring the soaked fresh silkworm chrysalis into a quick-freezing storage for quick freezing, wherein the temperature of the quick-freezing storage is -26 DEGC to -18 DEG C, and the quick freezing time lasts 1.5-2.5 hours; and (4) putting the quick-frozen fresh silkworm chrysalis into a sterile freshness-protection bag, putting a refrigeration storage forstoring at the temperature of -18 DEG C to -12 DEG C. The storage method of fresh silkworm chrysalis is simple and convenient to operate and enables effective sterilization, bacteria inhibition and oxidization prevention, the storage time of fresh silkworm chrysalis can be prolonged, and the best flavor and quality of fresh silkworm chrysalis can be kept.

Problems solved by technology

Although this method can prevent silkworm chrysalis from spoilage in a short period of time, it also has some shortcomings, such as fresh silkworm chrysalis inevitably contains some bacteria and fungi before quick freezing, and still undergoes complex physiological and biological changes. , its cells and tissues continue to carry out respiration and oxidation reactions. Over time, fresh silkworm chrysalis will still become rancid due to oxidation reactions and produce peculiar smell, resulting in shorter storage time.
