Embodiment 1

[0017] (1) Beating, enzymatic hydrolysis, filtration: using a material-to-liquid ratio of 1: 3, use a beater to beat the red duckweed for 3 minutes, then add protease (0.1% of the weight of the red duck pulp) and stir thoroughly, then let it stand for 1 hour for enzymolysis, then use Filter through an 800-mesh filter and take the supernatant for later use.

[0018] (2) Heating and fermentation: quickly put the supernatant obtained in (1) into boiling water and heat to 40°C, then add Lactobacillus bulgaricus (0.01% of the supernatant obtained in (1)), Streptococcus thermophilus (( 1) The mass of the supernatant taken is 0.01%), and fermented under airtight conditions for 36 hours.

[0019] (3) Membrane separation: Ultrafiltration of the fermented Hongping juice in (2) with a 10,000 Dalton membrane to separate whey solution and protein solution. (4) Adsorption, enzymatic oxidation decolorization: put the protein solution separated by (3) into activated carbon powder for adsorpt...

Embodiment 2

[0023] (1) Beating, enzymatic hydrolysis, filtration: using a material-to-liquid ratio of 1: 5, use a beater to beat the red duckweed for 5 minutes, then add protease (0.3% of the red duck pulp mass) to fully stir and let it stand for 2 hours for enzymolysis. Use a 2000-mesh filter to filter the supernatant for later use.

[0024] (2) Heating and fermentation: quickly put the supernatant obtained in (1) into boiling water and heat to 45°C, then add Lactobacillus bulgaricus (0.03% of the supernatant obtained in (1)), Streptococcus thermophilus (( 1) The mass of the supernatant taken is 0.03%), and fermented under airtight conditions for 48 hours.

[0025] (3) Membrane separation: Ultrafiltration of the fermented Hongping juice in (2) with a 50,000 Dalton membrane to separate whey solution and protein solution. (4) Adsorption, enzymatic oxidation decolorization: Put the protein solution separated by (3) into activated carbon powder for adsorption for 10 min, then filter to remo...

Embodiment 3

[0029] (1) Beating, enzymatic hydrolysis, filtration: using a material-to-liquid ratio of 1:4, use a beater to beat the red duckweed for 4 minutes, then add protease (0.2% of the red duck pulp mass) and stir thoroughly, then let stand for 1.5 hours for enzymolysis, Filter through a 1500-mesh filter to get the supernatant for later use.

[0030] (2) Heating and fermentation: quickly put the supernatant obtained in (1) into boiling water and heat to 42°C, then add Lactobacillus bulgaricus (0.02% of the supernatant obtained in (1)), Streptococcus thermophilus (( 1) The mass of the supernatant taken is 0.02%), and fermented under airtight conditions for 40 hours.

[0031] (3) Membrane separation: Ultrafiltration of the fermented Hongping juice in (2) with a 30,000 Dalton membrane to separate whey solution and protein solution.

[0032] (4) Adsorption, enzymatic oxidation decolorization: Put the protein solution separated by (3) into activated carbon powder for adsorption for 5-10...

Abstract

The invention provides a preparation method for azolla leaf protein and belongs to the field of food processing. Processes of enzymolysis, filtration, heating, fermentation, membrane separation, decolorization, vacuum freeze-drying and the like are adopted to solve problems in extraction and decolorization of the azolla leaf protein and produce the white grass-smell-free azolla leaf protein.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to a method for preparing red apple leaf protein. technical background [0002] Leaf protein coneentration (LPC) is a protein concentrate prepared from fresh green plant stems and leaves by pressing juice, separating juice protein, concentrating and drying. A large number of studies have shown that the nutritional value of leaf protein is extremely rich. Leaf protein contains 50%-65% of crude protein, 15%-30% of crude fat, 0.5%-1.5% of ash, 5%-20% of carbohydrates, and 0.5% of crude fiber. 11.5% (relatively wide range of values ​​due to differences between plant greens and treatments). Leaf protein protein contains 18 kinds of amino acids, of which 8 kinds of essential amino acids necessary for the human body are rich in content. Leaf protein has a complete range of amino acids and a balanced composition ratio, which is basically consistent with the adult amino acid patt...
