new transportation and preservation technology:
1. New film preservation: a one-time moisture absorption and preservation plastic packaging film developed by Japan. It is composed of two translucent nylon films with strong water permeability, and natural paste and sugar syrup with high osmotic pressure are installed between the films, which can slowly absorb the water seeping from the surface of fruits and meat to achieve the effect of preservation
2. Microwave preservation: a Dutch company disinfects fruits at low temperature. It uses microwave to heat them to 72 ℃ in a very short time, and then puts the processed food on the market at zero to four degrees. It can be stored for 42 to 45 days without deterioration. It is very suitable for supplying “seasonal fruits” in off-season, which is favored by people
3. Pressure preservation: the method of making food by pressure, which is successfully developed by the Institute of food science of Kyoto University, Japan, can prolong the preservation time and improve the fresh taste of fruits after pressure sterilization, but acid can not play a role under pressure. Therefore, it is best to preserve fruits under the best eating state.
dry goods can be vacuum packed by express delivery, and some ice cubes can be put in the fresh ones,
the way to preserve fresh beef and mutton during express delivery is to wash the fresh mutton, divide it into parts, and then pack them in fresh-keeping bags
