Evaluation device and evaluation method for aroma characteristics of thermosensitive essence

Abstract

The invention discloses an evaluation device and evaluation method for aroma characteristics of a thermosensitive essence. The device comprises a box body (1) of a main body; a heating tube (2) for heating the thermosensitive essence, and a sample tray (6) for bearing the thermosensitive essence to be tested are arranged in the box body (1); the sample tray (6) is located above the heating tube (2); the top of the box body (1) is provided with a sniffing port (3); the sniffing port (3) is connected with a sniffing conduit (4) extending out of the box body (1); and a digital temperature controller (5) is fixed on the wall of the box body (1) and is associated with the heating tube (2). The evaluation device disclosed by the invention can be used for rapidly evaluating the aroma characteristic expression of the thermosensitive essence along with the temperature change, is simple to operate and convenient to use, can be used for evaluating the same sample by multiple persons at the same time, is low in cost and small in size, and has a relatively good application prospect.

Description

Technical field[0001]The invention belongs to the technical field of devices for evaluating fragrance types and characteristics of flavors and fragrances, and specifically relates to a quick evaluation device and evaluation method for fragrance characteristics that can be used for heat-sensitive flavors.Background technique[0002]With the rapid development of society and economy, in order to satisfy people's pursuit of high-quality life, the application of flavors and fragrances is continuously expanding in all aspects of human life. The heat-sensitive flavor is a latent flavor flavor that has no fragrance at room temperature and gradually releases the fragrance as the temperature rises. It has been widely used in packaging materials, temperature prompts, and food flavors.[0003]At present, the evaluation of the aroma types and characteristics of heat-sensitive flavors mainly relies on the technical experience of the perfumers. The heating methods of the flavors mainly use simple meth...

AI Technical Summary

Problems solved by technology

[0003] At present, the evaluation of the aroma type and characteristics of heat-sensitive flavors mainly depends on the technical experience of the perfumers. The heating methods of the flavors mainly use simple means such as water bath, oil bath, hot air, etc., which has inaccurate heating temperature and is easy to be evaluated. Due to environmental interference and other issues, it is difficult to accurately obtain the aroma performance characteristics and aroma intensity changes of heat-sensitive flavors with temperature changes

For heat-sensitive flavors, there is no uniform quality evaluation method in the flavor and fragrance industry, nor is there a dedicated evaluation device
