Embodiment Construction

[0023] In order to further explain the method of σ-τ intensity method for the synergistic effect of alcohols and terpenes in the aroma compounds of chrysanthemum essential oil, the following examples are used for a more detailed description.

[0024] This method mainly uses the σ-τ intensity method to study the synergy between alcohols and terpenes in chrysanthemum essential oil, and the specific steps are as follows:

[0025] 1) Using squalane as the substrate, the actual concentration of terpenes in chrysanthemum essential oil was used to prepare terpene recombinant samples.

Abstract

The invention provides a method of analyzing the synergistic effect of fragrances from alcohol and terpene substances in chrysanthemum flower essential oil on the basis of a [sigma]-[tau] intensity method. The method includes the steps of: with squalane being a substrate, according to the practical concentration of terpene substances in chrysanthemum flower essential oil, preparing a terpene recombinant sample; measuring the intensity of the alcohol substances (A), the terpene recombinant sample (B) and a combination of both, and substituting the data into an intensity calculating equation; applying the data obtained in the above steps into a [sigma]-[tau] intensity model on Sigma Plot 12.0 software and analyzing change on the fragrance intensity values after combination of different alcohol substances and terpene recombinant samples, thus determining the influence on synergistic effect due to the component of the fragrance. Through the [sigma]-[tau] intensity method, the synergistic mechanism of the fragrances from alcohol and terpene substances in the chrysanthemum flower essential oil is analyzed, and change of the intensity of fragrances can be more intuitively reflected. The method illuminates the interaction between the fragrances of the alcohol and terpene substances, is simple in operation, has higher accuracy and is more extensive in application.

Description

technical field [0001] The invention belongs to the field of food science, and relates to a method for analyzing food flavor, especially a method for the synergistic effect of aroma of essential oils, specifically a method for analyzing alcohols and terpenes in chrysanthemum essential oil based on the σ-τ intensity method The method of aroma synergy. Background technique [0002] Chrysanthemum is one of my country's top ten traditional famous flowers, which has ornamental, edible and medicinal value. my country is the origin center of chrysanthemum and the distribution center of Chrysanthemum germplasm resources. There are more than 3000 chrysanthemum varieties, which were introduced into Europe and other places in the late Ming and early Qing dynasties. There are a lot of chrysanthemums planted in the central, eastern and southwestern parts of my country. [0003] The characteristic aroma of chrysanthemum essential oil is an important indicator for consumers to measure th...
