Problems solved by technology

However, due to the high brittleness of the rosin glyceride used as the main raw material, and the preparation of the product is mostly physical blending, the adhesion to poultry hair is poor during the depilation process, and it is easy to fall off
At the same time, the depilatory agent made from rosin glyceride has a high viscosity, which to a certain extent makes the poultry dehairing process inconvenient
In addition, the livestock and poultry emit peculiar smell during the depilation process, which does not allow the depilator to have a good working experience

Abstract

The invention discloses a bio-based depilating agent for livestock and poultry including the following raw materials by weight: 70-90 parts of food grade rosin glycerin esters, 4-6 parts of hyper branched polylactic acid grafting epoxy soybean oil, and 3-5 parts of hyper branched polylactic acid grafting gallic acid. The invention also discloses a preparation method for the bio-based depilating agent for livestock and poultry. The bio-based depilating agent for livestock and poultry improves the brittleness and the viscosity of the food grade rosin glycerin esters, has the good depilation effect, controls the peculiar smell of the livestock and poultry, and enables depilation staff to possess a good mood and experience.

Description

technical field [0001] The invention relates to the technical field of glue materials, in particular to a bio-based depilatory agent for livestock and poultry and a preparation method thereof. Background technique [0002] At present, most of the depilatory agents used for livestock and poultry processing on the market are industrial rosin and asphalt, and their main features are easy operation, good plucking effect and fast speed. However, because industrial rosin and asphalt are mainly extracted from petroleum or chemically synthesized, they contain heavy metals and toxic compounds that cannot be decomposed by the human body, such as benzopyrene and lead, which will harm the human digestive system and cardiovascular and cerebrovascular systems, especially liver and kidney functions. , Long-term consumption may even cause cancer. Livestock and poultry depilated with industrial rosin and asphalt, these substances will penetrate and remain in the cortex of livestock and poul...
