| description | The invention relates to a hair removal agent for poultry and livestock. The hair removal agent is characterized in that lactate oligomer with the number-average molecular weight of 500-10,000 is taken as a main body; lactic acid including L-lactic acid, D-lactic acid and D, L-lactic acid and alcohol perform a polymerization reaction for 4-5 hours at the temperature of 140-170 DEG C under the action of a catalyst and under the condition of low pressure, and the acid value is smaller than 10% after the reaction; then, a certain amount of anhydrous calcium sulfate which accounts for 10%-30% of the total mass is added, and the mixture continuously performs a reaction for 5-6 hours at the temperature of 120-150 DEG C under the condition of low pressure; finally, a food grade plasticizer is added and stirred, and the hair removal agent is obtained. The invention further discloses a using method of the hair removal agent for poultry and livestock. The added anhydrous calcium sulfate is cheap and can accelerate the reaction, and calcium sulfate can be used as a compound of the hair removal agent. According to the hair removal agent and the method, ingredients used in the hair removal agent are non-toxic and meet food safety requirements; and the processed poultry accords with national health standards and meets the requirements of customers. The melting temperature of the hair removal agent is in a range from 75 DEG C to 95 DEG C, and the viscosity is low; the operation is simple, and the hair removal efficiency is high; and the hair removal agent can be used repeatedly and is low in using cost. |
