Abstract

The invention discloses an extracting method of mango seed essential oil and application thereof in refreshment of pitaya. The extracting method of the mango seed essential oil comprises the following steps: drying, pulverizing, microwave pretreatment, super-critical CO2 extraction and two-stage molecular distillation. Mango seed crude essential oil obtained by super-critical CO2 extraction is subjected to second-stage molecular distillation to obtain mango seed essential oil, and the mango seed essential oil extracted by the extracting method of the mango seed essential oil is high in purity and small in purity. The mango seed essential oil is applied to refreshment of the pitaya, bacteria on the surface of the pitaya, inside the pitaya and in a storage environment can be killed, bacteria attack is prevented effectively, meanwhile, the mango seed essential oil has effects of resisting oxidation and clearing free radicals of the pitaya, brown stain of the pitaya is inhibited, melanin is inhibited, meanwhile, procyanidine in the pitaya can protect a fresh-keeping film of the pitaya against being decomposed, by the fresh-keeping film, the consumption speed of nutrients of the pitaya is reduced, rot and deterioration of the pitaya is slowed down, and the shelf life of the pitaya is prolonged.

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 dragon fruit 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...
