- Abstract
In order to investigate the effects of food bags with different thickness and sterilization time on the storage quality of sweet corn in vacuum packaging, packaging materials with two thicknesses(100, 120 μm) and two sterilization times(10, 15 min) were used to treat sweet corn, and the changes of color difference value, water content, hardness, ascorbic acid, soluble protein, soluble sugar and soluble solids content of sweet corn were measured during storage. The results show that: after 49 days of storage, the sweet corn packed in 120 μm vacuum bags and sterilized for 10 min has a moisture content of 75 g/(100 g), VC content of 26 mg/(100 g), soluble protein content of 4.1 mg/g, soluble sugar content of 51 mg/g, and soluble solids content of 11.8%, which is better than other treatment groups. After being packaged in 120 μm vacuum bags and sterilized for 10 min, the decrease of VC and soluble sugar content can be significantly delayed, and the increase of grain browning degree can be inhibited, which has the best effect on maintaining the edible quality of sweet corn. This study provides a certain reference for the storage and preservation of sweet corn.
