Method for establishing fingerprints of volatile components in agricultural products and their processed products

Abstract

The invention belongs to the technical field of food chemical pattern recognition, and in particular relates to a method for establishing fingerprints of volatile components of agricultural products and processed products thereof. At present, the main form of fingerprints for food chemical pattern recognition is the spectrum formed by the chromatographic elution curves of chemical components in geographical indication products. People cannot directly obtain relevant information about product quality, and it is not easy to understand intuitively, especially when analyzing When the system is very complex, the application and promotion of this type of fingerprint is limited. The present invention uses volatile components that can represent the sensory quality and style characteristics of agricultural products and processed products to express and analyze the fingerprint characteristics of samples, and establishes chemical pattern characteristics that can intuitively express the analysis objects to establish fingerprints to identify the characteristics and flavors of the objects. The present invention can be used as the objective chemical information barcode of the product itself, and the symbolic effect of expressing the uniqueness of the product is very obvious.

Description

technical field [0001] The invention belongs to the technical field of food chemical pattern recognition, and in particular relates to a method for establishing fingerprints of volatile components of agricultural products and processed products thereof. Background technique [0002] The quality, characteristics and style of agricultural products and their processed products are mainly determined by natural factors such as climate, geology, soil and overripe cultivars in the place of origin, and human factors such as cultivation management measures and processing techniques. The complex chemical composition and flavor characteristics in agricultural products and their processed products are closely related, and together they constitute the objective quality of the product. The protection system of geographical indication products has been implemented in foreign countries for more than 100 years. The earliest product to implement the protection system is wine. Countries with d...
