Problems solved by technology

[0007] In order to solve the deficiency of the existing hemp seed extraction technology, the present invention provides a method for preparing hemp protein from the defatted hemp seed residue, hemp protein It has a high solubility in hot water. Using hot water to extract hemp protein can improve the extraction efficiency of hemp protein. At the same time, it does not introduce impurities such as organic solvents and acid-base reagents. The extracted hemp protein does not need to be purified, and the remaining hemp seed residue It is free from pollution and can be used to make by-products such as feed or fertilizer, which improves the comprehensive utilization value of the hemp seed. The method includes the following steps:

Embodiment 1

[0033] (1) Weigh 50g of hemp seed residue, extraction process: feed the residue into the extraction tank, add 4 times the weight of hot water at 50°C to the extraction tank as the extractant, stir and extract at a constant temperature of 50°C for 1 hour , filtered, and the filtrate was placed in a concentration tank to collect the residue.

[0034] (2) Repeat the above step (1) leaching process once, and combine the filtrate in the concentration tank.

[0035] (3) Concentrate the filtrate in the concentration tank in step (2) at 55°C under reduced pressure to a concentrate with a relative density of 1.10 (measured value at 55°C), and accurately weigh the total weight of the concentrate to be 12.81g.

[0036] (4) Accurately weigh 2g of the concentrate, put it in a clean evaporating dish that has been dried to constant weight, evaporate to dryness in a water bath, dry in an oven at 105°C for 3 hours, take it out, cool it in a desiccator for 30 minutes to constant weight, and acc...

Embodiment 2

[0041] (1) Weigh 50g of hemp seed residue, extraction process: feed the residue into the extraction tank, add 6 times the weight of hot water at 70°C to the extraction tank as the extractant, stir and extract at a constant temperature of 70°C for 2 hours , filtered, and the filtrate was placed in a concentration tank to collect the residue.

[0042] (2) Repeat the above step (1) extraction process twice, and combine the filtrate in the concentration tank.

[0043] (3) Concentrate the filtrate in the concentration tank in step (2) at 60°C under reduced pressure to a concentrate with a relative density of 1.10 (measured value at 60°C), and accurately weigh the total weight of the concentrate to be 13.67g.

[0044] (4) Accurately weigh 2g of the concentrate, put it in a clean evaporating dish that has been dried to constant weight, evaporate to dryness in a water bath, dry in an oven at 105°C for 3 hours, take it out, cool it in a desiccator for 30 minutes to constant weight, and...

Embodiment 3

[0049] (1) Weigh 50g of hemp seed residue, extraction process: feed the residue into the extraction tank, add 8 times the weight of hot water at 90°C to the extraction tank as the extractant, stir and extract at a constant temperature of 90°C for 3 hours , filtered, and the filtrate was placed in a concentration tank to collect the residue.

[0050] (2) Repeat the above step (1) leaching process once, and combine the filtrate in the concentration tank.

[0051] (3) Concentrate the filtrate in the concentration tank in step (2) at 65°C under reduced pressure to a concentrate with a relative density of 1.12 (measured value at 65°C), and accurately weigh the total weight of the concentrate to be 13.16g.

[0052] (4) Accurately weigh 2g of the concentrate, put it in a clean evaporating dish that has been dried to constant weight, evaporate to dryness in a water bath, dry in an oven at 105°C for 3 hours, take it out, cool it in a desiccator for 30 minutes to constant weight, and ac...

Abstract

The invention discloses a method for preparing semen cannabis protein powder from degreased semen cannabis residue, relating to the technical field of development and application of semen cannabis. The method comprises the steps of with degreased semen cannabis residue as a raw material, carrying out hot water protein extraction, filtrating, concentrating filtrate, and drying under the assistance of a drying aid to obtain the semen cannabis protein powder. According to the method, hot water is used as an extractant to improve the extraction efficiency of semen cannabis protein; as impurities such as an organic solvent and a acid-base reagent are not added, the extracted semen cannabis protein is not required to be purified, and the remaining semen cannabis residue is not polluted and can be used for preparing byproducts such as feeds or fertilizers, and therefore, the comprehensive utilization value of the semen cannabis is improved.

Description

technical field [0001] The invention relates to the field of hemp development technology and its application technology, in particular to a method for preparing hemp protein powder from defatted hemp seed residue. Background technique [0002] Hemp seed, commonly known as hemp seed, hemp seed, and hemp seed, is one of the medicinal materials and health food raw materials used in traditional Chinese medicine in my country. "Chinese Pharmacopoeia" 2010 edition records: hemp seed is the moraceae plant cannabis Cannabis sativa L. of dry ripe fruit. The Ministry of Health's Health Law Supervisory Document [2002] No. 51 "Notice of the Ministry of Health on Further Standardizing the Management of Health Food Raw Materials" listed hemp seed in the "list of items that are both food and medicine". Studies have shown that hemp is rich in protein, mainly containing edseed globulin and edseed albumin, which are full-valent proteins that are easy to digest, can enhance the body's anti-f...
