Embodiment 1

[0017] A method for preserving fresh silkworm chrysalis, specifically the following steps:

[0018] (1) Cleaning of fresh silkworm chrysalis

[0019] The fresh silkworm chrysalis is first washed with a 2% sodium bicarbonate aqueous solution by mass fraction, and then soaked in an ethanol solution with a mass fraction of 25-30% for 5 minutes;

[0020] (2) Refrigeration of fresh silkworm chrysalis

[0021] The processed fresh silkworm chrysalis is frozen at -15°C for 2 minutes, and then transferred to 5-8°C for refrigerated treatment. During the refrigerated treatment, the fresh silkworm chrysalis is half-soaked in the soaking solution and kept in a ventilated and light-proof environment; Described soaking liquid is specifically made by following method:

[0022] A is calculated in parts by mass, and sodium citrate, sodium dihydrogen phosphate, potassium hydrogen tartrate, sodium acetate, and water are mixed in a mass ratio of 5:2:1:8:1000 to prepare solution A;

[0023] B is...

Embodiment 2

[0027] A method for preserving fresh silkworm chrysalis, specifically the following steps:

[0028] (1) Cleaning of fresh silkworm chrysalis

[0029] The fresh silkworm chrysalis is first washed with an aqueous solution of sodium bicarbonate with a mass fraction of 2%, and then soaked in an ethanol solution with a mass fraction of 25-30% for 10 minutes;

[0030] (2) Refrigeration of fresh silkworm chrysalis

[0031] The processed fresh silkworm chrysalis is frozen at -15°C for 5 minutes, and then transferred to 5-8°C for cold storage. During the cold storage, half-soak the fresh silkworm chrysalis in the soaking solution and keep it in a ventilated and light-proof environment; Described soaking liquid is specifically made by following method:

[0032] A is calculated in parts by mass, and sodium citrate, sodium dihydrogen phosphate, potassium hydrogen tartrate, sodium acetate, and water are mixed in a mass ratio of 5:2:1:8:1200 to prepare solution A;

Abstract

The invention relates to a preservation method of a fresh silkworm chrysalis. The preservation method particularly comprises the following steps of (1), cleaning the fresh silkworm chrysalis; (2), refrigerating the fresh silkworm chrysalis. Through an experiment, according to the preservation of the fresh silkworm chrysalis by using the method provided by the invention, the preservation time of the fresh silkworm chrysalis can be effectively prolonged; the survival rate of the fresh silkworm chrysalis can be still up to 82 percent or above after five days.

Description

technical field [0001] The invention belongs to the technical field of insect breeding, and in particular relates to a method for preserving fresh silkworm chrysalis. Background technique [0002] About 4 days after the silkworm spins the silk and forms a cocoon, it will turn into a silkworm chrysalis, which is a high-protein nutrient. Silkworm chrysalis is rich in protein and a variety of amino acids, and is a high-level nutritional supplement for the weak, sick, elderly and women after childbirth. Silkworm chrysalis can produce pharmacologically active substances, which can effectively increase the level of white blood cells in the human body, thereby improving human immune function and delaying the aging of human body functions. Silkworm chrysalis oil can lower blood fat and cholesterol, and has a significant effect on treating hypercholesterolemia and improving liver function. effect. [0003] In the prior art, fresh silkworm chrysalis is often preserved by cryopreserv...
