Abstract

The invention discloses a preservation method of freshly cut water chestnuts. The preservation method comprises the steps: washing fresh water chestnuts; soaking peeled water chestnuts in a preservative solution which is composed of tea polyphenols, sodium alginate, sodium diacetate and water; taking out the water chestnuts from the preservative solution, airing the water chestnuts at ordinary temperature, putting the water chestnuts into a plastic tray and wrapping the water chestnuts with a preservative film; and putting the water chestnuts into a modified atmosphere storage box. When the water chestnuts are put into a freezer for storage, the storage preservation time of the freshly cut water chestnuts can be prolonged to 18 days or more while maintaining the flavor of the water chestnuts, thereby realizing long acting preservation of the freshly cut water chestnuts; compared with single use of the freezer, the preservation time can be prolonged by more than 10 days; the color, browning degree and nutrient components of the water chestnuts all have no obvious change; and the preservation method is safe and green, conforms to the food safety requirements and has high reliability and low cost.

Description

technical field [0001] The invention relates to the technical field of horseshoe processing, in particular to a fresh-cut preservation method.
