Abstract
The extracting process of chitin and biological protein powder from raised fly includes: fly maggot or fly pupa material selection; soaking in NaOH solution of 2-3 % concentration at 90-100 deg.c for 10-15 hr; filtering to obain chitin as filtrated matter and filtrate protein liquid; soaking filtrate protein liquid in HCl solution of 2-3 % concentration to separate protein through deposition and subsequent filtering; water washing and stoving the chitin as filtrated matter and filtered protein separately to a water content lower than 10% to obtain the chitin and biological protein powder products. The chitin is used as fertilizer to raise the resistance of crop and prolong the fresh preserving period. The protein powder containing rice protein and amino acids is excellent feed for milk cow and laying egg.
Description
(1) technical field:
The present invention relates to the extracting method of chitin and biological albumen powder, be meant the technology of raising fly chitin extraction and biological albumen powder especially.
(2) background technology:
At present, the raw material of producing chitin mostly is shrimp, crab shell, adopts chemical process to obtain, complex process, and damage ratio is more serious, involves great expense.Chitin is at chromosorb, environmental protection, alpha-contamination purification, dyestuffs industries, the glass fibre arrangement, medicine, all many-sides such as pesticides farming fertilizer have been widely used, because of the problems affect of its cost development.Protein is to participate in animal life active major ingredient, at present, at under-developed country's protein provision amount famine, the people of muscular dystrophy is suffered from up to 8～1,000,000,000 in the whole world because of potein deficiency, as seen animal just more can not meet the demands to proteinic demand, causes milk, egg to yield poorly.Currently developed and developed biological albumen powder, the synthetic protein powder involves great expense, complex process.
(3) summary of the invention:
The present invention solves the problem of chitin extraction when extracting biological albumen powder emphatically, and the two cost is reduced greatly, satisfies various demands.
Technical scheme of the present invention is:
The first step: select materials, alkaline soak.Selecting inclusion-free fly maggot or fly pupa, is 2～3% NaOH solution with concentration, heats to 90～100 ℃, soaks 10～15 hours.
Second step: filter.With 80～100 mesh screens the above-mentioned bubble thing of invading is filtered, must leach thing chitin and filtrate protein liquid.
The 3rd step: add acid soak.With adding concentration in the filtrate protein liquid is 2～3% HCl solution, and making its pH value is 5～6, protein precipitation, and leach.
The 4th step: washing, oven dry.To leach the thing chitin and leach protein and wash with water respectively, and dry to water content and be lower than 10% to neutrality.Get chitin and biological albumen powder.Pulverize 100 order fineness packing.
The invention has the beneficial effects as follows: the fly resource is the widest, and the production reproduction speed is exceedingly fast, and a pair of fly bred since spring can provide kiloton protein powder and chitin the end of the year, and quantity is big, and technology is simple.The chitin of producing can be used for paper industry, and fields such as textile industry also can be used for pesticides farming fertilizer production, and is fertile as farming, can make crop improve the ability of disease and insect resistance, prolongs storage period, and agricultural product quality is improved greatly.Protein content height in the protein powder is rich in each seed amino acid, is the fine feed compound of livestock, can improve milk production of cow greatly, and the egg productivity of chicken has vast potential for future development.
(4) embodiment:
Embodiment 1
Choose the fertile big fly of body, make feed, breed into adult fly maggot or fly pupa 25 ℃ of temperature with slaughterhouse's tankage pig lung, chicken intestines, bean dregs and a fish mixture.
The method of chitin extraction and biological albumen powder:
The first step: select materials, alkaline soak.Selecting the inclusion-free fly maggot, is 2.5% NaOH solution with concentration, heats to 92 ℃ of immersions 12 hours.
Second step: filter.With 90 mesh screens above-mentioned soak is filtered, must leach thing chitin and filtrate protein liquid.
The 3rd step: add acid soak.With adding concentration in the filtrate protein liquid is 2.2% HCl solution, and making its pH value is 5.3, protein precipitation, and leach.
The 4th step: washing, oven dry.To leach the thing chitin and leach protein and wash with water respectively, and dry to water content and be lower than 10% to neutrality.Get chitin and biological albumen powder.Pulverize 100 order fineness packing.
The biological albumen powder outward appearance that this method is produced is pale brown toner shape, free from extraneous odour, protein content 85%～90%.Be rich in L-glutamic acid, arginine, each seed amino acid of L-Ala.Protein powder is mixed in all feeds, and making its content is 6%, and milk production of cow increases by 12%, and chicken egg productivity increases by 25%, and chitin is used in the agricultural fertile aspect of agricultural, makes the farm crop rate of fertilizer application reduce by 50%, and formulation rate reduces by 30%, and can realize green agriculture.
Embodiment 2
The method of chitin extraction and biological albumen powder:
The first step: select materials, alkaline soak.Selecting inclusion-free fly maggot or fly pupa, is 2.2% NaOH solution with concentration, heats to 98 ℃, soaks 14 hours.
Second step: filter.With 100 mesh screens the above-mentioned bubble thing of invading is filtered, must leach thing chitin and filtrate protein liquid.
The 3rd step: add acid soak.With adding concentration in the filtrate protein liquid is 2.8% HCl solution, and making its pH value is 6, protein precipitation, and leach.
The 4th step: washing, oven dry.To leach the thing chitin and leach protein and wash with water respectively, and dry to water content and be lower than 10% to neutrality.Get chitin and biological albumen powder.Pulverize 100 order fineness packing.
