Problems solved by technology

But some primary processed products are prone to browning
Because the phenolic compounds and polyphenol oxidase in the damaged parts such as cuts are in contact with the air, the phenols are oxidized to quinones, and then polymerized to form melanin, which causes the deterioration of the color of fruits and vegetables, and then leads to the decline of the flavor, texture and nutrition of fruits and vegetables. , causing losses to the emerging food industry

Abstract

The invention discloses a fresh-keeping method for fresh-cut fruits and vegetables through honey and plasma combined treatment, and belongs to the technical field of fresh-cut fruit and vegetable storage and fresh-keeping. Soaking the fresh-cut fruits and vegetables in the honey solution, and after soaking is finished, taking out and draining off the fresh-cut fruits and vegetables; the drained fresh-cut fruits and vegetables are exposed to plasma for treatment; and packaging the fresh-cut fruits and vegetables subjected to plasma treatment, and refrigerating and storing. The fresh-keeping method provided by the invention effectively solves the problem that the fresh-cut fruits and vegetables are easy to discolor, prolongs the shelf life of the fresh-cut fruits and vegetables, retains the specific nutritional value of the fruits and vegetables, and is green, safe, simple and easy to implement.

Description

technical field [0001] The invention relates to the technical field of storage and fresh-keeping of fresh-cut fruits and vegetables, in particular to a method for preserving fresh-cut fruits and vegetables through combined treatment with honey and plasma. Background technique [0002] With the development of central kitchens, fresh-cut fruits and vegetables are convenient, fast, nutritious and safe. These primary processed products have received extensive attention and the market has further expanded. Among them, apple is a kind of sweet and sour fruit with rich vitamin content and high nutritional value, which is very suitable for industrial production of cutting fruits and vegetables. But some primary processed products are prone to browning. Because the phenolic compounds and polyphenol oxidase in the damaged parts such as cuts are in contact with the air, the phenols are oxidized to quinones, and then polymerized to form melanin, which causes the deterioration of the co...
