Embodiment 1

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

[0032] First, 50kg of 85% D, L-lactic acid solution (471.8mol) and 1.44kg of glycerin (glycerin) (15.6mol) were used at 145°C~165°C, using stannous octoate as a catalyst, 0.5~5Kpa 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℃ temperature, using stannous octoate as a catalyst, and reacting for 20 hours under a pressure of 0.5-5Kpa. The obtained lactic acid oligomer is heated to 130°C to 160°C, 1kg 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 at 80°C~95°C for 3S, quickly put it into cold water at 20°C to cool for 30S, peel off the solid depilatory on the product, and get a clean and hairless product. The stripped solid depilatory Can be used again.

Embodiment 3

[0038] 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℃ temperature, using zinc oxide as a catalyst, and reacting for 22 hours under a pressure of 0.5-5Kpa. 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.

[0039] After immersing the poultry in the liquid depilatory at 80°C~95°C for 3S, quickly put it into cold water at 25°C to cool for 30S, peel off the solid depilatory on the product, and get a clean and hairless product. The stripped solid depilatory Can be used again.

Abstract

The invention relates to a poultry and livestock hair removal agent. The poultry and livestock hair removal agent comprises lactic acid oligomers with the average molecular weight of the lactic acid oligomers ranging from 500 to 30000, and the lactic acid oligomers are prepared by polymerizing lactic acids (including L-lactic acid, D-lactic acid, D, L-lactic acid) in the existence of catalyst under low pressure at the temperature of 140-170 DEG C. The invention further discloses a preparation method of the poultry and livestock hair removal agent. The ingredients of the hair removal agent are non-toxic and accords with food safety regulations, and processed poultries accord with national sanitary standards and meet the requirements of customers. Further, the lactic acid used in the hair removal agent is obtained by fermenting, discharge of 'three wastes' is avoided during preparation, and the preparation method is completely environment-friendly and meets the requirement of sustainable development. The melting temperature of the poultry and livestock hair removal agent ranges from 70 DEG C to 95 DEG C, and the poultry and livestock hair removal agent is low in viscosity, can be quickly solidified, is high in strength, easy to operate, fine in hair removal efficiency and low in cost and can be recycled and substitute for a rosin type hair removal agent.

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...
