Abstract

The invention discloses a method for studying the interaction of aroma substances in natural flowers and fruits. The method for studying the interaction of the aroma substances in the natural flowersand fruits comprises the following steps: (1) testing the actual aroma intensity of an aroma substance A in a mixed solution at different concentrations; (2) using a Steve model function I = k x C<n>to calculate the theoretical aroma intensity of the aroma substance A at different concentrations; (3) calculating the sum of squares of the differences between the actual aroma intensity and the theoretical aroma intensity at different concentrations of the aroma substance A; (4) calculating the k<mA> and n<mA> of the aroma substance A in step 3 by using a programming solution method; (5) repeating the method of steps 1 to 4 to obtain the n<MB> of another aroma substance B; and (6) calculating the absolute value (shown in the description) of the difference between n<mA> and n<mB>, and judgingthe interaction between the two aroma substances. The method for studying the interaction of the aroma substances in the natural flowers and fruits comprehensively and accurately studies the interactions between aroma substances, and can be widely used to design new natural flower and fruit flavor systems.

Description

technical field [0001] The invention relates to a method for studying the interaction of aroma substances in natural flowers and fruits. Background technique [0002] The characteristic aroma of natural flowers and fruits is deeply loved by people, and the related flavor and fragrance products have been widely used in food, daily cosmetics, textile, leather, papermaking and other industries, and are closely related to the national economy and people's life. At present, most of the flower and fruit flavor products independently developed in China have insufficient characteristic aroma coordination, realism and natural feeling, especially compared with the characteristic aroma of natural products, resulting in poor application effect in end products and cannot be used. Satisfying the needs of consumers has restricted the further development of the flower and fruit flavor industry. [0003] The reason is that the interaction relationship between the characteristic aroma substa...
