Example Embodiment

[0013] Embodiment 1: The extraction method of hemp seed storage protein of the present embodiment is carried out according to the following steps:

[0014] 1. Extraction: Grind hemp seeds into powder, add n-hexane to the powder in a ratio of 1:4 by weight of hemp seeds, extract at room temperature for 3 hours to obtain an extract, and then according to the ratio of hemp seeds by weight In a ratio of 1:6, n-hexane was added to the extract, and after standing overnight, the n-hexane was dried to obtain defatted hemp powder;

[0015] 2. Add deionized water to the defatted hemp powder in a ratio of 1:10 in parts by weight, shake and extract at 37°C for 1 hour, then place at room temperature, and then centrifuge at 8000g for 30 minutes to obtain the above The supernatant liquid A and the precipitate A were added into the precipitate A with deionized water in a ratio of 1:5 by weight. Liquid B and precipitation B, supernatant liquid A and supernatant liquid B are combined to obtain...

Example Embodiment

[0017] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the hemp seeds in step 1 are ground into powder by using liquid nitrogen. Other steps and parameters are the same as in the first embodiment.

[0018] In this embodiment, fresh hemp seeds are ground into as fine powder as possible with liquid nitrogen.

Example Embodiment

[0019] Embodiment 1 utilizes the method of the present invention to extract the storage protein of different components in the hemp seeds of Heilongjiang Province, and concrete steps are as follows:

[0020] 1. Extraction: Grind hemp seeds into powder, add n-hexane to the powder in a ratio of 1:4 by weight of hemp seeds, extract at room temperature for 3 hours to obtain an extract, and then according to the ratio of hemp seeds by weight In a ratio of 1:6, n-hexane was added to the extract, and after standing overnight, the n-hexane was dried to obtain defatted hemp powder;

[0021] 2. Add deionized water to the defatted hemp powder (hemp seeds are ground into powder with liquid nitrogen) in a ratio of 1:10 in parts by weight, shake and extract at 37°C for 1 hour, and then leave at room temperature. Centrifuge at 8000g for 30 minutes to obtain supernatant A and precipitate A, add deionized water to precipitate A according to the weight ratio of 1:5, shake and leaching at 37°C f...

Abstract

The invention discloses an extraction method of China-hemp seed storage protein, and relates to an extraction method of protein. The method solves the problem that an existing method for extracting the China-hemp seed storage protein is poor in effect. The extraction method of the China-hemp seed storage protein comprises the following steps: 1, extracting; 2, combining two centrifuged supernatants to obtain water-soluble protein; and 3, combining the two centrifuged supernatants to obtain salt-soluble protein. According to the method, the extraction of the China-hemp seed storage protein is realized, and the extraction effect is good. According to the extraction of the China-hemp seed storage protein, the China-hemp seed storage protein is primarily separated according to different solubility, then water-soluble protein and salt-soluble protein in China-hemp seeds are obtained respectively, the two proteins have different effects, and more scientific and more efficient proteins can be obtained according to actual requirements and different proportions. And the protein mixture has higher nutritional value.

Description

technical field [0001] The invention relates to a method for extracting stored protein. Background technique [0002] Hemp (industrial hemp) has been widely used as a fiber source for a long time. The earliest record can be traced back to more than 8000 BC, as hemp rope for pottery. About 2000 years ago, China invented papermaking in Cai Lun Before the craft, hemp was also used to make paper. [0003] In addition to fiber, in recent years, people have increasingly realized that hemp seeds are also a high-quality source rich in protein and oil. One of the more regions is China. Hemp contains 20-25% protein. Hemp seed storage protein is rich in 8 kinds of essential amino acids that cannot be synthesized by the human body. Its amino acid content is similar to soybean protein. Hemp seed storage The content of sulfur-containing amino acids in protein was significantly higher than that of soybean protein, and the content of sulfur-containing amino acids was proved to be related ...
