Abstract

The invention discloses an extraction method of mango stone essential oil and an application of the extraction method in banana preservation. The extraction method of the mango stone essential oil comprises steps as follows: drying, crushing, microwave pre-treatment, supercritical CO2 extraction and molecular distillation. Crude mango stone essential oil obtained through supercritical CO2 extraction is further subjected to molecular distillation, and the mango stone essential oil is obtained. The obtained mango stone essential oil has high purity and high plant polyphenol content and contains few impurities. The mango stone essential oil can kill microbial flora in banana peel, effectively prevent bananas from being infected by microorganisms and getting diseases in the storage process, prolong the guarantee period of the bananas and improve the aroma and the quality of the bananas after being applied to banana preservation; mango stone polyphenol in mango stones can be used for modifying soybean protein isolate-burdock oligosaccharides after being mixed with soybean protein isolate and burdock oligosaccharides under heating and stirring conditions, more stable membrane structures are formed on the surfaces of the bananas, respiratory action and moisture evaporation of the bananas are prevented, and the banana preservation effect is improved.

Description

technical field [0001] The invention relates to the field of food technology, in particular to a method for extracting mango kernel essential oil and its application in banana preservation. Background technique [0002] Known as the "king of tropical fruits", mango is rich in carbohydrates, protein, vitamins and multivitamins, and is rich in nutrition. Mango has smooth and tender flesh, sweet smell and special flavor, and is widely loved by people. Mango has a large core and contains protein, fat and carbohydrates. Mango core also has extremely high medicinal value. It has the functions of nourishing the kidney and dispelling kidney cold. It can be used in formulas for kidney deficiency, kidney cold, waist and leg pain, etc. Mango core contains phenolic substances, amino acids and various fatty acids. Among them, phenolic substances mainly include gallic acid, tannin, coumarin, coumarin, and mangiferin, and fatty acids contain stearic acid and oleic acid. Mango core conta...
