Seleniferous film coating agent for fresh preservation of large cherry

Abstract

A seleniferous film coating agent for fresh preservation of a large cherry comprises 0.5-1.5% of chitosan, 0.1-0.3% of sodium alginate, 0.01-0.5% of tea polyphenol, 1-3% of calcium chloride, 1-3% of vitamin C, 3-8% of fructose, 1-5% of sodium chloride, 3-8% of alcohol, 2% of acetic acid, 30-50% of sponge gourd water and the balance of water. With the adoption of the agent for the fresh preservation of the large cherry, the large cherry is not required to be cleaned any longer and can be directly eaten; the cherry is directly rich in selenium and delicious in taste and supplements a microelement, namely selenium, simultaneously; the storage and fresh preservation time of the large cherry is prolonged and can be up to 2.5-3.5 months without flavor reversion, that is, a color, brittleness and taste of the large cherry are not changed basically; after the large cherry is soaked, fly maggots concealed in the cherry can be thoroughly soaked out; the long-term problems of the industry are solved; and the agent is harmless to a body and can even be directly drunk.

Description

technical field [0001] The invention relates to the field of fruit preservation, in particular to a selenium-containing coating agent for preservation of large cherries. Background technique [0002] my country is rich in characteristic fruit resources. Among them, the big cherry is an important characteristic fruit in my country. The fruit industry is a pillar industry of my country's agriculture, which plays a pivotal role in ensuring farmers' income and promoting regional economic development. Fresh fruit is a fresh product, which has the characteristics of rapid ripening, aging, corruption, and easy deterioration of quality after harvest. Post-harvest losses are still quite serious. The annual loss due to rot is more than 100 billion yuan, which seriously restricts the distribution and distribution of these famous and high-quality fruits. [0003] At present, the storage methods of fruits and vegetables mainly include physical methods and chemical methods. Among them...

Problems solved by technology

[0004] Traditionally used chemical preservatives mainly include fungicides, such as prochloraz, carbendazim, diphenhydramine, thiabendazole, sulfur dioxide, and growth regulators, such as BA and 2,4-D, etc., but traditional chemical preservatives Environmental and food contamination caused by pesticide treatment has become a sensitive issue for consumers, and in some developed countries, chemical fungicides have been banned from use in fruit and vegetable post-harvest treatment. In addition, chemical preservatives have not fundamentally controlled fruit harvesting. The occurrence of later diseases; and the problem of drug resistance also makes chemical control technology face serious challenges
