Description
Technical field
The present invention relates to a kind of protein extracting method, specifically a kind of insect protein extracting method.
Background technology
Insect in the world there are about more than 100 ten thousand kinds, have more than 3650 to plant edible.Predicted according to brainstrust, to 21 century, elder brother
Worm will originate as the third-largest proteinoid for being only second to microorganism and cell biological, because caste is more, quantity is big, distribution
Extensively, breed fast, high protein, low fat, low cholesterol, rationally, fleshy fiber is few for trophic structure, is easy to absorb again, advantage is dashed forward
Go out, and be that countries in the world are of interest better than phytoprotein.
The carnivorism custom of China, it is with a long history, it is more prevailing in minority area.Vast territory and abundant resources for China, insect resources kind
Class is especially enriched.In recent years, once there is the product foreign exchange earning of locust, cicada.In the new resources exploitation seminar of following food, I
Ant is formally classified as new resources exploration project by the Ministry of Public Health of state.China also proposes to set up national resource insect industrial promotion committee member
Meeting, to promote the development and utilization of insect food and medicine.1994 years, celebrating Insects in China association 50 anniversaries of establishment
When, and 1996 years in National Resources insect industrialization seminar, be all solemnly proposed magnificence insect fete, expand significantly
The big edible influence of insect.Due to exploitation insect food and medicine, it can change harmful to treasure, achieve many things at one stroke, it is 21 century, emerging
One upsurge for establishing insect food industry is played, corresponding insect food and medicine will continuously emerge.
The leading food of 21 century is functional food, and the exactly typical functional food of insect food.In view of insect
It is the huge living resources of a major class development potentiality and nutrition treasure-house, energy medicine can be eaten, sportsman, the elderly, teenager can be used as
The senior nutrition of children and effective medicine.
Biological high-tech product --- insect protein Southern Yangtze University Foodstuffs Academy doctoral advisor Xia Wenshui is taught, group
Knit scientist in terms of state key subject Southern Yangtze University, 28 immunologys of Ge Rui biological studies mechanism, clinical medicine, science of heredity
Research cooperation, finally successfully develops albumen of new generation using biological enzymolysis patented technology from insect！Now, domestic-developed elder brother
Worm food, just as being a dark horse, sweeps across China.By years of researches, insect nutrient protein, insect active are largely extracted
Albumen, insect chitin（That is chitin）, and work out insect antimicrobial peptide, anti-cancer active matter etc..
The protein content of insect will be high than beef, pork, chicken, fish.For example, dry wasp contains protein about 81%, honey
Honeybee 43%, cicada 72%, grasshopper 70%, cricket 65%, oryza chinensis 60.08%, tussah chrysalis 52.14%, fly maggot 60.88%, yellow meal worm 63.19%,
Ancient cooking vessel reality thorniness ant 64.50%, red chest thorniness ant 58.60% etc., and the various amino acid wanted in protein rich in needed by human body, especially
It is the lysine, threonine, methionine that can not voluntarily synthesize etc..In addition, also containing a small amount of fat, carbohydrate, a variety of in polypide
Vitamin and mineral matter etc..Chitin can also be extracted from insect cuticle, antibacterial peptide etc. is extracted from blood.
It is typically all alkaline process and salt method that now popular insect protein, which is extracted, and alkaline process, salt method are all present
Shortcoming.Although alkalinity extraction recovery rate is higher, extract simple and easy to apply, production cost is relatively low, under conditions of high-alkali, albumen
A bad alanine can be generated in extract solution, this material is not only poisonous, but also can cause the loss of nutriment.Meanwhile, it is high
It can also cause protein to hydrolyze under the conditions of alkali, accelerate Maillard reaction, dark brown color substance be produced, so as to cause extract solution color
Deepen, nonprotein content increase in extract, separating effect reduction.In addition, alkaline process and salt method are to consersion unit
Requirement it is higher, can cause serious environmental pollution, increase the production cost of post processing.
