Device and method for analyzing flavour of blended vinegar

Abstract

The invention discloses a device and a method for analyzing the flavour of blended vinegar. The device comprises a data acquisition device and a computer, wherein the data acquisition device comprises a microprocessor, a sample chamber, a gas chamber, a gas sensitive sensor array and a first gas pump; an upper communication pipe and a lower communication pipe are arranged between the sample chamber and the gas chamber; a gas inlet is formed in the gas chamber and connected with the first gas pump via a first gas inlet pipeline; a gas outlet and a second gas pump are arranged on the upper communication pipe; a fourth electromagnetic valve is arranged at a top inlet of the gas chamber; a gas outlet electromagnetic valve is arranged at the gas outlet; and the gas sensitive sensor array is arranged in the gas chamber. According to the method, volatilization gas of the blended vinegar is detected via the gas sensitive sensor array, response signals generated by the gas sensitive sensor are sampled by the microprocessor, and the computer processes a sampling value and judges the flavour of the blended vinegar. The device and the method can differentiate the flavours of different kinds of blended vinegar, so as to bring convenience for manufactures to analyze and manage the flavour of the blended vinegar.

Description

technical field [0001] The invention relates to the technical field of food detection, in particular to a mixed vinegar flavor analysis device and method. Background technique [0002] Vinegar is a common condiment in people's daily life. Nowadays, there are more and more types of vinegar products, but the flavor of different vinegars has certain differences due to different factors such as production areas, ingredients, and fermentation methods, and has a certain impact on food. The flavor of the vinegar has some effect. If the flavor of vinegar is not suitable for consumers or is unstable, it will actually directly affect the market sales of products and relate to the benefits of producers. Therefore, during the research and development and production process of vinegar, manufacturers will conduct sensory evaluation on it. [0003] For a long time, people have judged the flavor of vinegar through their own senses, and this judgment is often highly subjective, and the res...
