Freshness-preserving treatment method of yellow peaches

Abstract

The invention discloses a freshness-preserving treatment method of yellow peaches. The freshness-preserving treatment method of the yellow peaches comprises the following processes: thoroughly washingselected yellow peaches, carrying out drying, carrying out pre-cooling, soaking the pre-cooled yellow peaches in pretreatment liquid, and packing the soaked yellow peaches in freshness protection packages, and carrying out storage. The pretreatment liquid is prepared by the following steps: S1, adding soybean protein and calcium chloride into an araboxylan aqueous solution, carrying out heating,and carrying out thermal-insulated water bath reaction so as to obtain modified araboxylan; S2, decocting crushed clove powder and radix astragali powder, carrying out extraction so as to obtain a drug solution, adding water and carrying out second extraction so as to obtain a second drug solution, mixing the two drug solutions, carrying out decocting so as to obtain an extractum, adding starch, and carrying out drying so as to obtain drug powder; and S3, dissolving vegetable oil, sucrose, ferric sulfate and resveratrol in water so as to obtain a solution, carrying out heating, carrying out thermal insulation, cooling the solution to room temperature, adding the modified araboxylan and the drug powder, and carrying out uniform mixing so as to obtain the pretreatment liquid. The freshness-preserving treatment method of the yellow peaches is capable of significantly prolonging storage life of yellow peaches, as well as preserving good flavor of the yellow peaches.

Description

technical field [0001] The invention relates to the field of fresh-keeping technology, in particular to a fresh-keeping treatment method for yellow peaches. Background technique [0002] Yellow peach, also known as yellow flesh peach, belongs to the genus Peach in the Rosaceae family. It is named for its yellow flesh. Regular consumption can play a role in laxative, lowering blood sugar and blood lipids, anti-free radicals, removing dark spots, delaying aging, improving immunity, etc., and can also promote appetite. It can be called a health-care fruit and a peach of health. [0003] Yellow peaches are very nutritious, rich in antioxidants, dietary fiber, iron calcium and various trace elements. Yellow peaches are soft but hard when eaten, more sweet and less sour, with aroma, medium water content, and a ripe sugar content of 14-15 degrees. [0004] Yellow peaches are prone to spoilage during storage and transportation, so it is necessary to keep them fresh. At present, t...

Problems solved by technology

At present, the fresh-keeping technologies for yellow peaches mainly include frozen fresh-keeping, modified atmosphere fresh-keeping and chemical fresh-keeping, etc., but the above-mentioned technologies have problems such as protein denaturation, nutrient loss and chemical residues, so safe and non-toxic biological fresh-keeping technologies are favored by people.
