Embodiment 1

[0031] A poultry and livestock hair removal agent is prepared as follows:

[0032] First, 50kg of D,L-lactic acid solution (471.8mol) with a content of 85% and 1.44kg of glycerol (glycerin) (15.6mol) were used at 145°C to 165°C, using stannous octoate as a catalyst, 0.5 to 5Kpa Under the pressure of reaction 20h. A new type of green depilatory can be obtained without adding other ingredients.

[0033] After immersing the poultry in the liquid depilatory at 80°C for 3S, quickly put it into cold water at 25°C to cool for 30S, and peel off the solid depilatory on the poultry to get a clean and hairless product. The stripped solid depilatory can be used again .

Embodiment 2

[0035] A new type of green depilatory agent for poultry and livestock. First, 60kg of 85% D, L-lactic acid solution (566.2mol) and 0.26kg of glycerin (2.8mol) are mixed at 145℃~165℃ Under the temperature, stannous octoate is used as a catalyst, and the reaction is carried out under the pressure of 0.5-5Kpa for 20h. The obtained lactic acid oligomer is heated to 130° C. to 160° C., 1 kg of epoxidized soybean oil is added therein, and stirred evenly to obtain the novel green depilatory agent of the present invention.

[0036] After immersing the poultry in the liquid depilatory agent at 80℃~95℃ for 3S, put it into the cold water at 20℃ to cool for 30S quickly, peel off the solid depilatory agent on the product, and get a clean and hairless product. The stripped solid depilatory agent Can be used again. Example 3:

Embodiment 3

[0037] A new type of green depilatory agent for poultry and livestock, 45kg of 85% D,L-lactic acid solution (424.6mol) and 0.65kg of glycerol (glycerol) (7.1mol) are mixed at 145℃~165℃ Under the temperature, zinc oxide is used as the catalyst, and the reaction is carried out under the 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 therein, and stirred evenly to obtain the novel green depilatory agent of the present invention.

[0038] After immersing the poultry in the liquid depilatory agent at 80℃~95℃ for 3S, put it into the cold water at 25℃ to cool for 30S, peel off the solid depilatory agent on the product, and get a clean and hairless product. The stripped solid depilatory agent Can be used again. Example 4:

Abstract

The present invention is a depilatory agent for poultry and livestock, which contains lactic acid oligomers. The number average molecular weight of the lactic acid oligomers is 500 to 30,000, and is composed of lactic acid (including L-lactic acid, D-lactic acid, D, L-lactic acid) and Alcohols are produced by polymerization in the presence of a catalyst at 140°C to 170°C and low pressure for 12 to 30 hours. The invention also discloses a preparation method of the above-mentioned poultry and livestock depilatory agent. The ingredients of the present invention are non-toxic and comply with food safety regulations; the processed poultry meets national health standards and meets consumer requirements; and the lactic acid used in the present invention is derived from fermentation, and there is no "three wastes" emissions during the preparation process, which is completely It is a green and environmentally friendly process that meets the requirements of sustainable development. The depilatory agent of the present invention has a melting temperature of 70°C to 95°C, low viscosity, solidifies quickly after cooling, high strength, simple operation, and good depilatory efficiency; it can be used repeatedly, has low cost, and can replace rosin depilatory agents.

Description

technical field [0001] The invention relates to a novel green poultry and livestock hair removal agent used in food processing and a preparation method thereof. Background technique [0002] At present, in my country's poultry processing, there are still many small hairs on the poultry after mechanical depilation, especially on the wings, legs, and abdomen; Difficult to remove. Many processors use rosin containing heavy metals and toxic compounds and pitch containing a large amount of carcinogenic benzene series to depilate. These toxic substances will contaminate poultry and livestock meat, thereby endangering human health. Therefore it is of great practical significance to study a new type of non-toxic and harmless food-safe depilatory. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a non-toxic, harmless, good depilatory effect, reusable and economical poultry and livestock depilatory agent. [0004] The tec...
