Description

technical field [0001] The invention relates to a quick-freezing and fresh-keeping method for fresh fruit, in particular to a quick-freezing and fresh-keeping method for jujube. Background technique [0002] Present prior art, golden shredded jujube is a kind of well-known at home and abroad, fresh fruit, is a kind of fruit produced in specific area, fresh food period is short, deep processing period is short. With the general cold storage method, due to its own respiration, nutrient loss; appearance changes, wrinkles appear on the surface, and the taste is poor. Measured by relevant departments: zinc: 3.4mg / kg, iron: 6.7mg / kg, vitamin C: 210-280mg / 100g, calcium: 22.6 mg / 100g, total sugar: 28.75%. The existing fresh-keeping storage method has a short storage period and a lot of nutrient loss, and cannot effectively prolong the deep processing period and fresh food period. Contents of the invention [0003] The purpose of the present invention is to provide a method for q...
