Gas High Permeability and Ethylene Adsorption Active Packaging for Strawberry Preservation

摘要：

　　In order to extend the preservation of fresh strawberries,an ethylene adsorption active package with gas high permeability was developed.The high permeability of packaging material is made of molecular sieve modified low-density polyethylene (LDPE) film.Before the films were heat sealed to bags,a 3g molecular sieve sachet together with fresh strawberries was put into each package to prolong the storage periods.These packaging and control strawberry samples were stored at 5±1 ℃.The gas concentration inside the packaging,VC content,total acidity,TSS,rot rate,weight loss and firmness of the preserved strawberries were tested over 13 days storage.The experimental date revealed that the gas high permeability films combined with ethylene absorbent treatment showed the lowest rot rate,and the highest preference value compared with the control samples,which proved the feasibility of this novel packaging.
