Embodiment 1

[0016] (1) Take 100 kg of walnut protein powder, add 960 kg of drinking water, and mix well; (2) Replace chelation: add 3.6 kg of malic acid, then adjust the pH of the slurry to 3.4 with 3.0mol / L hydrochloric acid, add 320 grams of chlorine Zinc chloride, mixing, keep 3.4 hours under 52 ℃, constantly stir during, and stirring speed is 4400 rev / mins; (3) adsorption reaction: add 3.6 kilograms of microcrystalline cellulose (average particle diameter is 340 meshes) in walnut protein slurry ), stirred at 52°C for 50 minutes, and the stirring speed was 4800 rpm; (4) solid-liquid separation: solid-liquid separation was carried out to remove insoluble solids; (5) tempering: adjust the pH of the walnut protein slurry to within 15 minutes 6.5; (6) Sterilization, dehydration and drying: the slurry is sterilized, then dehydrated and dried to obtain the product.

Embodiment 2

[0018] (1) Take 100 kg of walnut protein powder, add 960 kg of drinking water, and mix well; (2) Replace chelation: add 3.6 kg of malic acid, then adjust the pH of the slurry to 3.4 with 3.0mol / L hydrochloric acid, add 320 grams of chlorine Zinc, mixed, kept at 52 ° C for 3.4 hours, during which the stirring speed was 4400 rpm; (3) tempering: adjust the pH of the walnut protein slurry to 6.5 within 15 minutes; (4) sterilization, Dehydration and drying: the slurry is sterilized, then dehydrated and dried to obtain the product.

Embodiment 3

[0020] (1) Take 100 kg of walnut protein powder, add 960 kg of drinking water, and mix well; (2) Chelation: add 3.6 kg of malic acid, then use 3.0mol / L hydrochloric acid to adjust the pH of the slurry to 3.4, and keep it at 3.4 at 52°C hour, during which the stirring speed was 4400 rpm; (3) tempering: adjust the pH of the walnut protein slurry to 6.5 in 15 minutes; (4) sterilization, dehydration and drying: the slurry was sterilized, and then Dehydration and drying to obtain the product.

[0021] Effect analysis of different embodiments:

[0022]

[0023] Note: The higher the score of sensory quality, the better the taste

[0024] Compared with Examples 2 and 3, the arsenic and copper contents of Example 1 processed by the present invention were reduced to 0.028mg / kg and 0.071mg / kg respectively; Basically the same.

[0025] The present invention uses zinc ions to replace and chelate under specific circumstances, and the content of arsenic and copper decreases; after cont...

Abstract

The invention relates to a method for synchronously reducing the contents of arsenic and copper in walnut protein. The method disclosed by the invention comprises the following steps of taking walnut protein powder, performing pulp blending, performing substitution and chelating, performing an adsorption reaction, performing solid-liquid separation, performing conditioning, performing sterilization, performing dehydration, performing drying and the like. According to the method disclosed by the invention, the contents of the arsenic and the copper in the walnut protein can be effectively and synchronously reduced, and besides, the feeling quality and the nutrient value of the walnut protein cannot be influenced.

Description

technical field [0001] The invention relates to a method for synchronously reducing the content of arsenic and copper in walnut protein, belonging to the field of agricultural product processing. Background technique [0002] Walnut protein has a good amino acid composition ratio and high digestibility. It is an excellent vegetable protein and has important utilization value. In recent years, with the development of industry and mining, the problem of heavy metal pollution has been gradually exposed. Arsenic and copper are attached to walnut protein, which affects the edible safety of walnut protein. After being eaten, proteins rich in arsenic and copper can accumulate in living organisms, seriously endangering human health. Contents of the invention [0003] The invention aims to provide a method with simple method and reasonable cost to reduce the content of arsenic and copper in walnut protein and improve food safety. [0004] A method for synchronously reducing arse...
