Embodiment 1

[0018] Example 1 A protein health product using dried barley larvae as raw materials, and its preparation method includes the following steps:

[0019] Using the dried barley larvae as the raw material, the raw material is crushed to a particle size of 0.1mm using a dry mill. A 60% volume concentration ethanol solution was used for pre-leaching at a temperature of 40°C for 6 hours, and then cyclic leaching 5 times, each for 1 hour, for degreasing. Then, under the conditions of pH 5 and temperature of 40° C., bromelain is selected to hydrolyze the defatted material for 10 hours, and the mass concentration of bromelain is 1%. Use filter press to remove water insoluble matter in the system. Then use the nanofiltration membrane to remove 50% of the inorganic salts and moisture in the system. Finally, spray drying the concentrated solution to obtain barley insect protein nutritional powder.

[0020] Using this scheme, the extraction rate of barley insect protein reaches 75%, and the ...

Embodiment 2

[0021] Example 2 A protein health product prepared from dried barley pupa as a raw material, the preparation method includes the following steps:

[0022] Using the dried barley insect pupae as the raw material, the raw material is crushed to a particle size of 1 mm using a dry mill. Use the ethanol solution with a volume concentration of 80% to pre-extract at 70°C for 2 hours, and then cyclically extract 3 times, each for 3 hours, for degreasing. Then, papain is selected to hydrolyze the defatted material for 1 h under the conditions of pH 7 and temperature 60°C, and the mass concentration of the papain is 5%. Use centrifugation to remove water-insoluble matter in the system. Then use the nanofiltration membrane to remove 90% of the inorganic salts and moisture in the system. Finally, freeze-dry the concentrated solution to obtain barley insect nutritional protein powder.

[0023] Using this scheme, the extraction rate of barley insect protein reaches 80%, and the molecular wei...

Embodiment 3

[0024] Example 3 A method for preparing protein health products by using dried worm bodies of adult barley insects as raw materials, and the preparation method includes the following steps:

[0025] Using the dried body of the adult barley insect as the raw material, the raw material is pulverized to a particle size of 0.5mm using a dry mill. A 95% volume concentration ethanol solution was used for pre-extraction at 55°C for 4 hours, and then cyclic extraction 4 times, 2 hours each time, for degreasing. Then, under the conditions of pH 9 and temperature of 45° C., the degreasing material is hydrolyzed for 5 hours, and the mass concentration of the 2709 alkaline protease is 3%. Use filter press to remove water insoluble matter in the system. Then use the nanofiltration membrane to remove 70% of the inorganic salts and moisture in the system. Finally, spray drying the concentrated solution to obtain barley insect protein nutritional powder.

[0026] Using this scheme, the extracti...

Abstract

The invention provides a barley pest protein health-care product and a preparation method thereof. The method comprises steps as follows: dried pest bodies of barley pest larvae, pupae or adults are taken as a raw material, and the raw material is crushed into the particle size of 0.1-1 mm by a dry crusher; circular digestion degreasing is performed with an ethanol solution with the concentration being 60%-95%; protease hydrolysis is performed under the conditions that the pH value ranges from 5 to 9 and the temperature is 30-60 DEG C for 1-10 h, and the mass concentration of protease is 1%-5%; water-insoluble substances are removed through centrifugation or filter pressing; 50%-90% of water and inorganic salt in a system are removed through filtration by a nanofiltration membrane; finally, drying is performed through a spray drying or freeze drying process, and a finished product is obtained. The protein health-care product taking barley pest as a raw material is provided and has a remarkable health-care effect. Mouse tests prove that the health-care product has anti-fatigue and athletic injury recovery promoting effects on mice.

Description

Technical field [0001] The invention relates to a protein health product and a preparation method thereof, in particular to a barley insect protein health product and a preparation method thereof. Background technique [0002] Barley insects are large in size and high in nutritional value. They are mainly used as live feeds for reptiles abroad, while in my country they are mainly used as feeds for high-end pets, artificially farmed fish, birds and other insectivores. Barley insect larvae have high nutritional content. Dry larvae contain 38.99% fat, 49.51% protein, and are also rich in various minerals and vitamins. [0003] Studies have shown that barley insect protein can significantly increase the weight and endurance of mice, increase the protein content in muscles, and have obvious protective effects on tissue damage caused by exercise, and accelerate the recovery speed after exercise and improve the anti-fatigue ability. There is no report that barley insects are harmful to t...
