Embodiment 1

[0040] In the early stage of R&D, the R&D personnel screened different hydrolysis systems (hydrochloric acid, acetic acid, sodium hydroxide, potassium hydroxide, alkaline protease B8360, acid protease B8410, papain G8430) based on amino content as an indicator, and finally screened out ammonia water-pineapple Protease system, and optimize it to obtain the most suitable process for preparing rice bran vegetable protein liquid:

[0041] 1) Add 1.0kg of rice bran protein powder to 3kg of purified water and ultrasonically swell at 50°C for 24h;

[0042] 2) Add 0.2kg of ethylenediaminetetraacetic acid, continue ultrasonication for 30min, and then filter with a filter membrane with a pore size of 2 microns;

[0043] 3) Put the filter cake in 5kg of deionized water, add 0.01kg of sodium dodecylsulfonate, stir and dissolve evenly, then add ammonia solution to adjust the pH to 7.5-8.2, control the temperature to 60-65°C and stir for 1-2h Alkaline treatment solution;

[0044] 4) Add p...

Embodiment 1-A

[0049] Compared with Example 1, the difference is that the pH in step 3) is adjusted by sodium hydroxide to be 8.0, that is, sodium hydroxide is used to replace the ammonia solution, and the rest are exactly the same as in Example 1.

Embodiment 1-B

[0051] Compared with the examples, the difference is that sodium hydroxide is used to adjust the step 3) without adding ammonia solution to carry out the preliminary treatment of alkali, directly adopting potassium dihydrogen phosphate to adjust the pH to 7.0-7.5, and then adding bromelain 0.06-0.08kg to control Enzymolysis was carried out until the temperature was 50-55°C for 5-6 hours; the rest were exactly the same as in Example 1.

[0052] Table 1 is the detection result of the amino group content of the rice bran vegetable protein liquid prepared by embodiment 1 and its embodiment 1-A, 1-B:

Abstract

The invention belongs to the biotechnology field, and particularly discloses a rice bran vegetable protein formaldehyde remover. According to the rice bran vegetable protein formaldehyde remover, ammonium hydroxide-bromelain can be adopted for hydrolyzing rice bran proteins to obtain rice bran vegetable protein liquid, and the rice bran vegetable protein liquid is used as a formaldehyde removing active ingredient to prepare the novel rice bran vegetable protein formaldehyde remover. The prepared novel formaldehyde remover is stable in physicochemical property, environment-friendly, free of pollution, good in water solubility, convenient to use and high in formaldehyde removing rate.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a rice bran plant protein formaldehyde remover and a preparation method thereof. Background technique [0002] Formaldehyde is a colorless gas with a pungent smell and is easily soluble in water. In the indoor environment, formaldehyde mainly comes from various boards, insulating materials and coatings. It is a carcinogenic and teratogenic substance identified by the World Health Organization. It is also a potential strong mutagen. Long-term exposure to formaldehyde gas will not only cause damage to the contact organs and respiratory system, but also cause chronic poisoning, certain damage to the reproductive system and immune system, and endanger health. [0003] At present, the formaldehyde removers with high sales volume and widely used in the market are mainly divided into two types: photocatalyst formaldehyde remover and biological enzyme formaldehyde remover. The ...
