Can the meat with plastic packing bag be pressed directly with a pressure cooker?
Health performance indicators have two senses, toluene amine, evaporation residue (4% acetic acid), evaporation residue (n-hexane), evaporation residue (65% ethanol), Potassium Permanganate (water consumption), heavy metals (as Pb), decolorization, solvent residue, sterilization indicator.
It is better not to use a plastic bag directly with a pressure cooker heating, because it is said that plastic bags at high temperatures easy to precipitate toxic substances, so remove plastic bags and then heating for good, so as not to affect the health.
The plastic composite film (bag) products used in food packaging have 8 national and trade standards, and the main standards are divided into physical and mechanical performance indexes and sanitary performance indexes. The indexes of physical and mechanical properties are mainly tensile strength (or tensile strength), elongation, peel strength, heat resistance strength, Charpy impact energy, water vapor permeation amount and the amount of oxygen through the bag, bag, pressure resistance, heat resistance and dielectric performance drop, oil resistance, cold resistance, heat resistance etc.;
