A biochemical-physical comprehensive long-term fresh-keeping and storage method for juicy peaches

Abstract

The invention belongs to the technical field of fresh keeping and storage of edible fruits, and specifically relates to a biological chemical physical comprehensive long-acting fresh-keeping and storage method for honey peach. The method comprises: performing conventional processes comprising ultraviolet ray irradiation and precooling treatment on honey peach; combining multiple chemical and biological fresh-keeping single methods, and selecting a combination of 5-10 wt% of ginger extraction, 0.5-1.5 wt% of chitosan oligosaccharide, 1-2 wt% of pullulan and 1-1.5 wt% of calcium chloride to spray or immerse honey peach; placing honey peach in a bamboo-charcoal corrugated box made of Ag<+> modified bamboo charcoal, and placing the corrugated box in a clean and draughty environment; and sterilizing and disinfecting the environment before storing. The storage time of honey peach is 15-18 days at a high-temperature condition (30 + / - 5 DEG C), and the healthy fruit rate with 15 days is 90%. Compared with the conventional fresh-keeping method, the method of the invention has the advantages of no any environmental pollution, simple production condition requirements and lower treatment cost, and is applicable to large-scale industrialized fresh-keeping and storage line production of hone peach, and the method has effective, safe, economical and feasible effects.

Description

technical field [0001] The invention belongs to the technical field of freshness preservation of edible fruits, and in particular relates to a biochemical-physical comprehensive long-term preservation and storage method for juicy peaches. Background technique [0002] Peach is an important fruit originally produced in my country. It has the characteristics of delicious meat and rich nutrition. It is deeply welcomed by the people. my country is the largest country in peach production. It is an international problem. Since peaches are juicy and fleshy fruits, there is no post-ripening period after harvesting. The best quality, flavor, and color are formed during the development of the tree. And improved. Therefore, it is impossible to produce high-quality fruit from early-picked fruit; in addition, peaches are highly respiratory fruits with respiratory climacteric changes. The fruit softens rapidly in a very short period of time, loses nutrients very quickly, easily loses wate...
