A kind of extraction method of passionflower aroma components

Abstract

The invention belongs to the technical field of extracting aroma substances of passionflower, and discloses a method for extracting aroma substances of passionflower, which uses absolute ethanol as a solvent for ultrasonic extraction, magnetic heating and stirring, and concentrates and collects a passionflower aroma extract. , to analyze and detect the collected passionflower aroma component concentrate, and use the NIST spectral library to search to determine the chemical composition of its aroma. The invention utilizes the solvent extraction distillation method to extract the characteristic aroma components of passionflower, and the extraction method can be effectively used for extracting the aroma components of passionflower and other fruits. The aroma components of passion fruit juice are the general term for volatile and aromatic substances that can produce a certain odor. It is the main factor that affects the fresh eating and processing quality of passion fruit. Master the technology of efficiently extracting the aroma components of passion fruit. It will have a good promotion effect on passionflower deep processing industries such as passionflower juice and flavor processing.

Description

technical field [0001] The invention belongs to the technical field of extracting aroma components of passionflower, in particular to a method for extracting aroma components of passionflower. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] As a tropical plant that is easy to grow and survive, and has strong adaptability, passionflower has high juice content, rich nutrition, unique flavor, and comprehensive aroma of various fruits. It occupies a very important position in the international beverage market. Passiflora is rich in polysaccharides, enzymes, carotenoids, organic acids, amino acids, multivitamins and beneficial trace elements such as phosphorus, iron, calcium, selenium, etc. Among them, the content of vitamin C is relatively high, so it is the king of vitamin C. reputation. [0004] Passiflora is distributed in warm and humid areas in southern my country, such as Guangdong, Guangxi, Haina...

AI Technical Summary

Problems solved by technology

However: the extraction purity of ether and n-hexane is low, and the extraction amount of n-hexane is the lowest; the boiling point of ether is low, and the equipment requirements are high; the neurotoxicity of ether and n-hexane is high, and the solvent residue in the extract is harmful to the human body

[0007] (2) prior art does not utilize absolute ethanol as solvent ultrasonic extraction, magnetic heating and stirring, rotary evaporator to extract concentrated passion fruit pulp aroma components
