Embodiment 1

[0034]Embodiment 1: take the edible insect of black grasshopper cicada, locust as example, when this raw material mainly depends on the occurrence of this pest in nature, catch and buy at the place of occurrence, such as Shaanxi province Guanzhong area can buy cicada pupae and locust in large quantities every year in July-August . Raw material collection plan: organize a purchase network in the place where the pest occurs, train purchasers, and equip each purchase point with processing equipment and storage equipment. According to the amount of occurrence in the year, the purchase price is determined in real time, and the quality of the purchase is strictly inspected and controlled. Raw material processing process: Site acceptance—cleaning—soaking in water at any temperature between 50°C and 100°C (such as 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100°C) for 1- For 10 minutes, carry out enzyme curing treatment—sprinkle the amount of salt that is 2% to 10% (such as any content w...

Embodiment 2

[0038] Embodiment 2: Take Tenebrio molitor (also known as Chinese shrimp) as an example, the edible insects are produced and cultivated in an industrialized manner. After nearly ten years of breeding, a relatively ideal Chinese shrimp group has been screened out. Its species The quality standard is: the number of worms per 100 grams is less than 600 (the number of worms per 100 grams of common worms is more than 700), strong activity, good disease resistance, strong feed adaptability, low cost, and the reproduction rate is 150 times--380 Times, no degradation within 5 generations. In industrialized breeding, production breeding and breeding farms are set up, and the species used for production are replaced every 3 generations of breeding to ensure the quality of breeding products. In the breeding, the EM (compound microorganism) and lactic acid bacteria fermentation technology in the research results of animal husbandry are used to produce straw fermented feed, and the traditi...

Embodiment 3

[0039] Embodiment 3: Take the edible insects of tussah silkworm and silkworm as examples, train farmers and collective sericulture industry, and collect them after pretreatment as before as required. Silkworm chrysalis after silk reeling contains industrial alkali and pupa odor, which can be directly used for food processing and affect product quality. Therefore, tussah silkworms and silkworms are used as raw materials for food, and cocoons should be cut to obtain live pupae in cooperation with sericulture production. The output of live tussah silkworm chrysalis is relatively large, and some provinces have more than 300 tons of raw materials every year. It is more convenient to take live pupae and freeze them directly. After the tussah silkworm and silkworm are reeled, the cocoons are cut to get live pupae, and the live pupae are directly frozen and stored for later use. In the same way, the same as the procedure of the previous embodiment 1.

Abstract

The invention relates to chitosan for edible insects like cicada and river shrimp and grasshopper and silkworm chrysalis, as representatives. Nowadays, the developed product in the market at home and abroad mainly includes special animal feed and edible insect food, and a quantity of insect raw material is exported as pet feed. The objective of the invention is treating the redundant insect skin filter off during edible insect treating process. The production method and application of the chitosan for edible insect realizes the commercial process and mass production. Technology is as follows:crushing and beating, separating, degreasing, decalcifying, deacetyling, decolouring, vacuum freeze drying, and meshing the edible insect skin to get the finished product. Effects are as follows: thechitosan, as the polymer material, is of unique property, safety and innocuity, well applied range, and becomes the industry raw material for making high added value byproduct in many fields like food field, medical field, cosmetic field, agriculture field, chemical industry and environmental protection field.

Description

1. Technical field [0001] The invention relates to an edible insect chitosan, a production method and an application (purpose) of the edible insect chitosan. Insects mainly represented by edible insects such as cicadas, Chinese shrimps (also known as Tenebrio molitor, the same below), locusts and silkworm chrysalis. 2. Background technology [0002] At present, the research direction of the development of insect resources at home and abroad is mainly to seek low-cost farming and industrial production of insects; to study functional substances in insects that have development potential. The developed products in the domestic and foreign markets mainly include special animal feed and edible insect table dishes, and a certain amount of insect raw materials are exported to Western Europe, South Korea and Japan every year for pet feed, among which the main ones are Chinese shrimp, cicada and silkworm chrysalis. There is no report on edible insect chitosan and its production meth...
