Pigskin is a high protein content meat raw material, its protein content of up to 26.4%, of which collagen content of 87.8%, far higher than the protein content of pork lean. Pork skins made from raw pork skin, pork skin, frozen skin, ham and other meat products are not only good in toughness but also have excellent color, aroma, taste and texture, and they are also suitable for human skin, tendons, bones and hair. There are important physiological health effects. Therefore, in recent years, pigskin-based foods have been rapidly developed, and the demand for pigskin is also increasing. However, the processing method must be standardized and the processing quality is particularly important. 1. Selection of materials: Use raw quarantine qualified pigs as raw materials, and do not use males, female sows and pigs suffering from skin diseases. 2, scalding and shaving: using a good hair removal method can guarantee clean pigskin, reduce hair and hair root residue. For this reason, the method of hair removal after scalding in a scalding tank is usually used. According to the data, the temperature of the hot pool is 48-60°C, and the scalding time is 5-7 minutes. When the scald is hot, the carcass should be continuously turned so that the various parts can be evenly heated, and the scalding can be prevented. When using a scalding machine, pigs are only given one pig per stall to avoid squeezing each other, uneven heating on the surface, and affecting the scalding effect. After the carcass is fully bubbling, the carcass is rapidly shaved and the hair is scraped and kept clean. When using a hair-trimming machine, the temperature of the bath water in the machine is controlled at about 30°C, which does not harm the subcutaneous fat. 3. Peeling: Clean the carcass surface before peeling and avoid skin damage when peeling. Therefore, mechanical peeling is usually used to make the skin less damaged, even and thin, and to reduce the residual under the skin. 4. Forming and packaging: The pre-cooled pigskin is cut into sizes not smaller than 10 cm and 25 cm in size, and quantitatively packaged (120 kg or 125 kg), lined with plastic film, and packed in cartons. 5. Preservation of pigskin: Store at -18°C for up to 10 months. Processed normal pigskin has the following characteristics: white and shiny skin, fine and deep pores; thorough hair removal, no residual hair, hair roots; no skin and skin diseases; no subcutaneous tissue, fat to clean; good shape; cooked After having the normal color, aroma, taste, taste soft, good toughness, clear broth, cold jelly was colorless.
