Edible packaging packaging field

The Japan Food Circulation System Association developed a new fresh-keeping packaging carton that uses a silicate called “Ristoval” as an additive for pulp. This kind of stone powder has a good absorption effect on various gases. It is inexpensive and does not require low-temperature and high-cost equipment. It has a long-term preservation effect and the weight of fresh fruits and vegetables will not be reduced.
A Japanese packaging company has also recently developed a new one-time consumption of moisture-absorbing plastic packaging film. It is composed of two translucent nylon membranes with strong water permeability, and is filled with natural paste and high osmolarity sugar syrup between the membranes. It can slowly absorb moisture that oozes from the surface of vegetables, fruits and meat. , so as to achieve the purpose of preservation.

It can be applied to apples, citruses by spraying, brushing or dipping. The surface of fruits, vegetables, watermelons, bananas, tomatoes, etc. Because this preservative forms a layer of sealing film on the surface of fruits, it can prevent oxygen from entering the interior of fruits and vegetables, thereby prolonging the ripening process and playing a role in freshness preservation. The preservation period of fruits and vegetables coated with this preservative can be up to 200 days or more. . The best part is that this preservative can also be eaten with fruits and vegetables.
