Problems solved by technology

[0010] In summary, the antioxidant peptides disclosed in the above two patent applications are all extracted from collagen, and these collagens are extracted from pigs, cattle, chickens, fish, turkey and other animals, so the raw materials are limited, so the The extraction method described is complex
However, the prior art does not disclose the method of extracting antioxidant peptides from vegetable protein powder. Therefore, researchers use this as a starting point to conduct research and obtain the present invention

Embodiment 1-5

[0095] Embodiment 1-5 relates to the preparation of industrial hemp seed protein powder

Embodiment 1

[0097] The hemp seeds for industrial use are screened to remove impurities, then graded, and then mechanically hulled and shelled; the hemp seeds obtained after shelling are subjected to carbon dioxide supercritical extraction, extracted at 43°C and 34MPa for 2 hours, and the extracted oil is extracted and the extracted product is crushed , extracted under the above conditions for another 2 hours to obtain industrial hemp seed low-temperature protein meal after oil extraction. In the low-temperature protein meal of hemp seeds for industrial use, the residual oil rate is 1.5%. The obtained low-temperature protein meal is pulverized by a pulverizer, passed through a 60-mesh sieve, and 10 kg of the sieved protein meal is taken, added to 100 kg of warm water at 50°C, stirred evenly, and the pH value is adjusted to 9.5, keep stirring for 15 minutes, vacuum filter to remove insoluble impurities, and obtain crude protein solution. Adjust the pH value of the crude protein solution to...

Embodiment 2

[0100] The hemp seeds for industrial use are screened to remove impurities, then graded, and then mechanically hulled and shelled; the hemp seeds obtained after shelling are subjected to carbon dioxide supercritical extraction, extracted at 43°C and 34MPa for 2 hours, and the extracted oil is extracted and the extracted product is crushed , extracted under the above conditions for another 2 hours to obtain industrial hemp seed low-temperature protein meal after oil extraction. In the low-temperature protein meal of hemp seeds for industrial use, the residual oil rate is 1.2%. The obtained low-temperature protein meal is pulverized with a pulverizer, passed through an 80-mesh sieve, and 10 kg of the protein meal after sieving is taken, added to 80 kg of warm water at 45° C., stirred evenly, and the pH value is adjusted to 8. Insulated and stirred for 25 minutes, vacuum filtered to remove insoluble impurities, and crude protein solution was obtained. Adjust the pH value of the ...

Abstract

The invention relates to a preparation method and application of industrial hemp seed antioxidant peptide. In the method, industrial hemp seed meal obtained after low-temperature oil extraction and a cheap and easily-obtained enzyme preparation are employed to prepare hemp seed protein antioxidant peptide zymolyte through enzymatic hydrolysis; the degree of hydrolysis is 15-20% and molecular weight distribution is 350-2000Da; the zymolyte is subjected to static or dynamic desalting by macroporous absorption resins, vacuum concentration and freeze drying to obtain industrial hemp seed protein antioxidant peptide. The obtained product has wide capability of scavenging free radicals. The invention has the advantages of simple sources of raw materials and process flow, high nutritive value, easy absorption by human bodies, strong capability of scavenging free radicals and capabilities of resisting fatigue and improving human body immunity; therefore, the product of the invention has broad application prospect, can be used as a nutrition enhancer, an additive in health products, beverages and cosmetics and an antioxidant in food and can be applied to the medical field.

Description

technical field [0001] The invention relates to a preparation process of bioactive peptides, more specifically, a preparation method and application of industrial hemp seed antioxidant peptides. Background technique [0002] Oxygen free radicals can cause cell damage and death, and are closely related to the occurrence of skin aging, pigmentation, wrinkles and certain skin diseases, as well as the oxidative rancidity of food. With the improvement of living standards, people's requirements for nutritional intake are getting higher and higher. Antioxidant peptides prepared from plant proteins have attracted increasing attention due to their advantages of high safety, good functionality, and low price, and have great application prospects in the fields of food and medicine. [0003] Cannabis has a long history of cultivation and is one of the earliest crops. Archaeological data show that my country is the earliest area to domesticate, grow and process cannabis, about 5000-600...
