Embodiment 1

[0029] A depilatory agent is prepared as follows:

[0030] First, 50kg of 85% D, L-lactic acid solution (471.8mol) and 1.44kg of glycerol (glycerin) (15.6mol), at 145℃~165℃, use stannous octoate as a catalyst, 0.5~5Kpa Reaction for 20h under the pressure No other ingredients are added to obtain a new green depilatory.

[0031] After immersing the poultry in a liquid depilatory at 80°C for 3S, quickly put it in cold water at 25°C to cool for 30S, and peel off the solid depilatory on the poultry to obtain a clean and hairless product. The stripped solid depilatory can be used again .

Embodiment 2

[0033] A new type of green depilatory for poultry and livestock, first mix 60kg of D, L-lactic acid solution (566.2mol) with 85% content and 0.26kg of glycerol (2.8mol) at 145℃~165℃ At temperature, use stannous octoate as a catalyst, and react for 20 hours at a pressure of 0.5-5Kpa. The obtained lactic acid oligomer is heated to 130°C to 160°C, 1 kg of epoxy soybean oil is added thereto, and the mixture is stirred uniformly to obtain the new green depilatory agent of the present invention.

[0034] After immersing the poultry in a liquid depilatory at 80℃~95℃ for 3S, quickly put it in cold water at 20℃ to cool for 30S, and peel off the solid depilatory on the product to obtain a clean and hairless product. The stripped solid depilatory Can be used again.

Embodiment 3

[0036] A new type of green depilatory for poultry and livestock, first mix 45kg of 85% D, L-lactic acid solution (424.6mol) and 0.65kg of glycerin (7.1mol) at 145℃~165℃ At temperature, zinc oxide is used as a catalyst, and the reaction is carried out at a pressure of 0.5-5Kpa for 22h. The obtained lactic acid oligomer is heated to 130° C. to 160° C., 1.6 kg of calcium carbonate and 0.6 kg of soybean oil are added thereto, and the mixture is stirred uniformly to obtain the new green depilatory agent of the present invention.

[0037] After immersing the poultry in a liquid depilatory at 80℃~95℃ for 3S, quickly put it in cold water at 25℃ to cool for 30S, and peel off the solid depilatory on the product to obtain a clean and hairless product. The stripped solid depilatory Can be used again.

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 [0003] The technical problem to be solved by the present invention...
