Processing method for high-quality, low-sugar content plum slice

The invention provides a processing method for a high-quality, low-sugar content plum slice. The flow of the method is as follows: semifinished fruit pickling, picking and washing, desalination, core removal, pulping, flavoring, shaping, drying, slicing and finished product packaging. Because the processing method adopts flowing hot water to carry out gradient desalination, the process of desalination is accelerated, and the loss of heat energy is reduced; since semifinished plums are pulped, the subsequent process of flavoring is facilitated, the pickling time spent in whole fruit processingis saved, the loss of nutrients is prevented in the process of pickling, overall drying is facilitated, and the uniformity of the color of the product is guaranteed; because xylitol is directly addedto replace the osmotic cane sugar adopted by the conventional process, the processing period is greatly shortened, and the sugar content in the product is decreased; after pulp is scraped into pieces, the pieces are dried under vacuum and constant temperature, and cut into the plum slices with uniform size and thickness, the plum slices are neat and attractive, the product keeps the original color and flavor, the original nutrient ingredients are prevented from being destroyed as well, and moreover, the plum slices are convenient to eat.

Melon and fruit antiseptic and fresh-keeping agent, preparation method thereof and melon and fruit storage method

The invention discloses a melon and fruit antiseptic and fresh-keeping agent. The antiseptic and fresh-keeping agent comprises the following raw materials: 0.04%-0.1% parts of scutellaria baicalensisextract, 0.1%-0.15% parts of clove oil, 0.04%-0.1% parts of cinnamon oil, 0.05%-0.1% parts of saponin extract, 0.15%-0.2% parts of patchouli oil, 0.15%-0.2% parts of calamus oil, 0.3%-0.5% parts of camellia meal extract, 1.3%-5.5% parts of emulsification thickener, 2.3%-7% parts of other additives, the balance water, and the total amount of raw materials is 100%. The invention also discloses a kiwi fruit antiseptic and fresh-keeping agent, a preparation method thereof and a melon and a melon and fruit storage method. The raw materials of the plant-derived antiseptic and fresh-keeping agent ofthe present invention are all plant-derived extracts, without any chemical organic reagents, and have good antiseptic and fresh-keeping effect. After being mixed with water, the agent can be used to form a film on the surface of fruits and vegetables to inhibit the growth of pathogenic bacteria. At the same time, the film can reduce and inhibit the physiological metabolism of the fruit after harvest, thereby improving the quality of the fruit, and extending shelf life.
