Hebei develop edible composite fruit and vegetable cling film

Kangzhuang New Resource Technology Research Institute of Hebei Province has successfully developed edible functional composite fruit and vegetable preservation films, which are welcomed by farmers.
It is understood that the plastic wrap formed on the surface of fruits and vegetables is composed of antioxidants, inhibitors, sterilizing agents, color-retention agents, film formers and other components that have been scientifically compounded. The coating film preservation operation is convenient, only the picked fruits and vegetables are put into a prepared film preservation liquid for several seconds, and then taken out and naturally dried or dried with natural wind, the surface of the fruits and vegetables can form a layer of semi-permeable, Transparent plastic wrap. Stored in a cool room or cellar for long-term preservation and storage, the preservation period of common varieties is as long as 4 months; varieties that are not easy to keep fresh, such as litchi and strawberry, can also be up to 1 month or more.
Traditionally, the preservation of fresh fruits and vegetables is generally based on cold storage. The large investment in equipment and the high preservation cost make it difficult for general growers to popularize and popularize, and the fruits and vegetables after refrigeration have higher requirements for transportation and sales. The production of the edible composite fruit and vegetable cling film technology overcomes the inconvenience of refrigeration and provides an economical and practical way of preserving fruits and vegetables.
