Insect bioprotein extract, and preparation method and application thereof

Abstract

The invention belongs to the technical field of natural active ingredient extraction, particularly relates to an insect bioprotein extract and further discloses a preparation method and an applicationof the insect bioprotein extract. The insect bioprotein extract takes a gecko, a scorpion and a centipede as insect raw materials; the obtained extract has a better uric acid reduction effect, can effectively alleviate and treat a gout symptom and can be used for preparing a pharmaceutical preparation for treating gout. According to the insect bioprotein extract, active ingredients of the insectprotein are extracted by a combined water extraction and CO2 supercritical extraction manner; compared with the conventional water extraction or alcohol extraction manner in the prior art, an active ingredient dissolution rate of the prepared extract is higher; a raw material utilization ratio is further increased; and the extract has the better uric acid reduction effect.

Description

technical field [0001] The invention belongs to the technical field of extracting natural active ingredients, in particular relates to an insect biological protein extract, and further discloses its preparation method and application. Background technique [0002] According to statistics, there are more than 1 million species of insects in the world, of which more than 3,650 species are known to be edible. Insects have the characteristics of many types, large numbers, wide distribution, and rapid reproduction. Insects contain high protein, low fat, and low cholesterol, and have the advantages of reasonable nutritional structure and less meat fiber. And attracted the attention of countries all over the world. Experts predict that by the 21st century, insects will become the third largest source of protein after microorganisms and cell organisms. [0003] According to reports, the protein content of insects is higher than that of beef, pork, chicken, and fish. For example, ...

Problems solved by technology

Among them, although the extraction rate of alkaline extraction is high, the extraction is simple and easy, and the production cost is low, under the condition of high alkali, lys-alanine will be generated in the protein extraction solution, which is not only poisonous, but also Causes the loss of nutrients; and under high alkali conditions, it will also cause protein hydrolysis, and accelerate the Maillard reaction, resulting in dark brown substances, which will cause the color of the extract to deepen, the non-protein content in the extract will increase, and the separation effect will decrease.

In addition, the existing alkaline and salt extraction methods have high requirements for reaction equipment, and will cause serious environmental pollution and increase the production cost of post-processing
