Abstract

The invention provides a preservation method capable of prolonging the storage time of apples. The preservation method comprises the following steps: S10, sprinkling of salt water; S11, selection of apples; S12, precooling; S13, preservation; and S14, packaging. Directed at the physiological characteristics of apples and problems existing in preservation and storage of apples, salt water is sprinkled onto fresh apples in 10 days before plucking, then the plucked apples are precooled, and finally a preservative prepared from waste residues of scented tea is used for soaking of the apples, so the method produces good preservative effect. The method can effectively prolong the fresh-keeping and storage time of the apples, and maintains the appearance quality and nutritional and edible value of apples in a preservative period.

Description

technical field [0001] The invention belongs to the technical field of fresh-keeping, and in particular relates to a fresh-keeping method capable of prolonging the storage time of apples. Background technique [0002] Apple is a good beauty product, which can not only lose weight, but also make the skin smooth and tender. Apple is a low-calorie food, which only produces 60 kcal per 100 grams; the nutrients in apples are highly soluble and easily absorbed by the body, so they are called "living water", which is good for dissolving sulfur elements and making the skin smooth and tender.
