Embodiment 1

[0038] 1. Select 80 parts of fresh sterile fly maggots and put the obtained press filter into a container containing 100 parts of concentration of 3% sodium hydroxide solution after filter press filtration, and stir at normal temperature for 2 hours to obtain sodium hydroxide Decomposition solution, spare;

[0039] 2. Filter the standby sodium hydroxide decomposition solution in step 1 with a 300-mesh nylon filter cloth to obtain the filtrate, for subsequent use, discard the insolubles (materials that do not pass through the filter cloth);

[0040] 3. Put the spare filtrate in step 2 into a container containing 100 parts of hydrochloric acid solution with a concentration of 1 mot / L, adjust the pH to 6.0±0.5, let stand at room temperature for 6 hours to precipitate the protein, and then separate the supernatant from the protein precipitate , get the protein precipitate, set aside, discard the supernatant;

Abstract

The invention discloses a method for preparing insect protein powder by using sterile fly maggot; the sterile fly maggot, which is the larva bred by the fly eggs laid by cultured sterile adult fly, is treated with pressure filtration, decomposition, filtration, adjustment of pH value, precipitation, washing and drying to be prepared into the insect animal protein powder; wherein, pressure filtration is conducted by a frame filter, decomposition is carried out in 1-5% of sodium hydroxide water solution, filtration is implemented with a piece of 200-350 meshes of filter cloth, 1mol / L hydrochloric acid solution is used for adjusting pH value, the protein is precipitated by standing still at room temperature, the precipitated protein is washed to neutrality with water and then prepared into milky white insect protein powder by a high speed centrifugal spray dryer; the content can reach over 90%. The protein powder prepared by the invention is rich in various nutrient components, has low fat, low cholesterin, little meat fiber, reasonable trophic structure and easy absorption, and can improve the immunity of the human body, resist aging, and achieve multiple effects such as disease prevention, nourishment, health care, physical rehabilitation and the alike, thus the insect protein powder has promising application prospect in the field of the medicines and health products for resisting fatigue and improving immunity.

Description

technical field [0001] The invention relates to biological products, in particular to a method for preparing insect protein powder with sterile fly maggots, and also relates to the application of the insect protein powder prepared with sterile fly maggots. Background technique [0002] In the insect world, houseflies are the most numerous insects. The life cycle of houseflies is short. Artificially raised houseflies only need 4-5 days from eggs to mature larvae, which is much shorter than the cycle of raising other insects; The larvae of houseflies, referred to herein as maggots. Fly maggots are used as medicine, and the "Compendium of Materia Medica" records: "Maggots, also known as 'grain worms', 'Luo Xianzi', and 'water fairy', can treat sweet and hot children, and are good medicine for malnutrition." In recent years, fly maggots have applied for Chinese patents to concentrate on the following three aspects: one, fly maggots as feed raw materials or feed additives: as Ch...
