This invention discloses a method for
removing hair from
animal skin suitable for
food processing, belonging to the field of
food processing technology. The method employs a two-stage process of "pretreatment + targeted
hair removal." First, glycosidase pretreatment degrades the
protein-
polysaccharide complex in the intercellular spaces of the epidermal cells, clearing the
permeation barrier without damaging
subcutaneous fat. Then, charge
adaptation technology is used, utilizing
enzymatic hydrolysis to naturally lower the pH of the
system. Initially, the
enzyme molecules carry the same charge as the
hair follicle permeation channels, enhancing
permeation efficiency. Later, as the pH decreases, the charge of the
enzyme molecules reverses, targeting and binding with the charge of the matrix surrounding the
hair follicle, achieving
hair removal. This method overcomes the limitation of two-sided permeation, achieving highly efficient one-sided permeation
hair removal, avoiding the need for
degreasing and preserving
subcutaneous fat to the maximum extent. Furthermore, the process completely avoids the use of chemical additives that
pose food safety risks or damage
flavor. It offers high hair removal efficiency and minimal loss of
skin collagen, providing a safe and efficient hair removal solution for
animal skin food processing.
