Problems solved by technology

[0003] At present, many scholars have devoted themselves to the research on the performance optimization of protein foaming agents. For example, adding sodium dodecylbenzenesulfonate, sodium lauryl sulfate and gelatin to the animal protein liquid to optimize the foaming agent. Compound modification, the foam stability of the modified foaming agent has been significantly improved, but the bad smell of animal protein has not been effectively controlled, see the preparation and foaming performance test of animal protein concrete foaming agent, Yin Bing et al., New Building Materials, 2007, July; there is also a study on the preparation of soybean protein isolate and soybean whey protein by alkali-soluble acid precipitation and enzymatic hydrolysis. The results show that after 30 minutes of enzymatic hydrolysis, the solubility and foaming properties of soybean protein Stability has been enhanced, see the research on soybean protein used as beer foam stabilizer, Sun Linlin et al., Food Science, 2007, 28, 12; by adding composite fibers, adsorbents, and reducing agents to silkworm chrysalis protein powder for deodorization and anticorrosion Yes, through the addition of a large number of chemicals, the apparent quality of protein powder has been significantly improved, see the research on deodorization process of silkworm chrysalis protein powder, Jin Xiaoming et al., Food Science, 2005, 26, 9
The above-mentioned methods have all achieved the improvement of some properties of the protein foaming agent to a certain extent, but these methods or operations are cumbersome, or the cost is high, or the effect is not comprehensive, or the chemical reagents introduced have brought new peculiar smells, all of which are unsatisfactory

Abstract

The invention relates to a hair protein foaming agent and a preparation method thereof. Firstly, the hair protein liquid is taken and the pH value is adjusted to 7.5-9, and then hydrogen peroxide is added to obtain a mixed solution; the mixed solution is irradiated; Precipitate, and dry the obtained supernatant to obtain a hair protein foaming agent. In the present invention, the hair protein liquid is oxidized with hydrogen peroxide and irradiated, so that the macromolecular protein is partially degraded, more hydrophobic groups are exposed, the surface properties of protein molecules are improved, and the foamability and foam stability are enhanced. ; At the same time, a large number of active free radicals generated destroy the characteristic functional groups of the color-forming substance, achieving the purpose of decolorization. At the same time, the volatile odorous substances are also changed under the action of strong oxidation, achieving the purpose of deodorization.

Description

【Technical field】 [0001] The invention belongs to the field of foaming agents, and in particular relates to a hair protein foaming agent and a preparation method thereof. 【Background technique】 [0002] The main sources of traditional protein foaming agents are animals and plants. Among them, the foaming agent made from vegetable protein has excellent performance and good sensory quality, but the cost of raw materials is very high and it is difficult to popularize and apply; the foaming agent made from animal protein , bad smell, serious pollution, high cost and no market advantage; in recent years, with the in-depth research on waste recycling, hair protein has gradually attracted people's attention. This kind of protein avoids the high cost and bad smell of vegetable protein. The degree is lighter than animal protein, so it is an excellent material to develop foaming agent. However, studies have shown that if hair protein is directly used as a foaming agent without any tr...
