Problems solved by technology

my country's fruit production is very rich, and autumn is the harvest season of fruit every year. A large number of fruits are harvested one after another. However, the fruits are not easy to preserve after collection, and are easily affected by various factors and deteriorate and rot, causing serious economic losses to farmers. Therefore, the use of scientific and reasonable storage and preservation technology can effectively prolong the storage period of fresh fruits, adjust the off-season and peak season, and prosper the fruit market, which has significant economic and social benefits
[0003] The technologies widely used for fruit preservation include room temperature preservation, low temperature preservation, cellar preservation, ozone preservation, chemical preservation, etc. Among these fruit preservation technologies, people mainly use chemical preservation to preserve fruit. However, although chemical preservation is used to Fruits have a good fresh-keeping effect, but many chemical synthetic substances are harmful to human health, even poisoning and carcinogenic, which are extremely harmful

Abstract

The invention provides a natural food preservative used for fruits and preparation thereof. The preservative comprises first smearing liquid and second smearing liquid, wherein the first smearing liquid comprises the following ingredients by weight percent: 0.8%-1.4% of carboxymethyl cellulose, 1-2% of maltodextrin, 0.3%-0.8% of baking soda and the balance of deionized water; the second smearing liquid comprises the following ingredients by weight percent: 1%-1.5% of konjak gum, 0.2%-1% of beewax, 0.5%-2.5% of plant extract, 1%-5% of a solvent and the balance of deionized water. The preservative adopts natural ingredients for protection, is green and safe, achieves the effects of water retention, oxidization resistance, antibiosis and corrosion prevention of the fruits sequentially through multilayer spraying, has multiple functions, effectively reduces metabolism after the fruits are picked, prolongs the preservative period for 15 days or more, has good color keeping and flavor keeping properties, and improves the fruit marketing performance.
