Feather removing agent and preparation method thereof

Abstract

A depilatory agent of the present invention, it comprises lactic acid oligomer, and described lactic acid oligomer number average molecular weight is 500~30000, is made of lactic acid (comprising L-lactic acid, D-lactic acid, D, L-lactic acid) and alcohols In the presence of a catalyst, it is prepared by polymerization at 140°C to 170°C and low pressure for 12 to 30 hours. The invention also discloses a preparation method of the depilatory agent. The ingredients of the present invention are non-toxic and comply with food safety regulations; the processed poultry conforms to national hygiene standards and meets the requirements of consumers; moreover, the lactic acid used in the present invention comes from fermentation, and there is no discharge of "three wastes" in the preparation process, completely It is a green and environmentally friendly process that meets the requirements of sustainable development. The depilatory agent of the invention has a melting temperature of 70°C to 95°C, low viscosity, rapid solidification after cooling, high strength, simple operation and high hair removal efficiency; it can be used repeatedly and has low cost, and can replace rosin depilatory agents.

Description

Technical field

[0001] The invention relates to a new type of green depilatory used in food processing and a preparation method thereof. Background technique

[0002] At present, in poultry processing in my country, there are still many small hairs on the poultry body after mechanical dehairing, especially the wings, legs, and abdomen, which are difficult to remove. In the dehairing process of domestic animals, especially pig heads and trotters, the skin is thicker and the roots are deeper. Hard to get rid of. Many processors use rosin containing heavy metals and toxic compounds and asphalt containing a large amount of carcinogenic benzene series to remove hair. These toxic substances can contaminate the meat of poultry and livestock, thereby endangering human health. Therefore, it is of great practical significance to study a new non-toxic and harmless depilatory that meets food safety. Summary of the invention
