Method for detecting aromatic matter of passionflower

Abstract

The invention belongs to the technical field of detection of aromatic components, and discloses a method for detecting an aromatic matter of passionflower. The method comprises the steps of extractingfor 10, 20, 30, 40, 50 and 60 minutes separately at 30, 40, 50, 60 and 70 DEG C heating temperature by using a headspace solid phase microextratcion-gas chromatography-mass spectrometry technology; analyzing extraction rates and relative contents of seven characteristic aromatic matters of different extraction temperature and different extraction time periods, so as to obtain an optimal extraction temperature, 50 DEG C, and extracting for 30 minutes. In the method, the characteristic aromatic matters of passionflower are detected and analyzed through a headspace solid phase microextratcion-gas chromatography-mass spectrometry instrument. The detection method can be widely used for detecting aromatic matters of passionflower and other fruits. The passionflower, as a tropical plant, has high survival rate and strong adaptability, has high content of fruit, is nutritious, has unique flavor, and has a fragrance of multiple fruits, thereby being an important beverage raw material in the international beverage market.

Description

technical field [0001] The invention belongs to the technical field of detection of aroma components, and in particular relates to a detection method of passion fruit aroma substances. 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, Hainan, Yunna...

AI Technical Summary

Problems solved by technology

[0007] (1) In the prior art, the steam distillation method will cause the decomposition products of the original aroma components due to thermal degradation, and the chemical components will suffer a certain loss

[0008] (2) Solvent extraction method, the steps are cumbersome, the types of compounds extracted are less, organic solvents may react with aroma substances, and the experimental mechanism is not clear

[0009] (3) Adding sodium chloride during the extraction of aroma components will help the extraction efficiency to some extent, but it will cause dehydration of the juice and destroy the physical state of the juice
