Abstract

The invention relates to a prediction method for distinguishing different production places of Xinjiang walnuts based on an infrared spectroscopy technology, and belongs to a non-destructive technology for rapid detection and monitoring of food quality and safety. According to the present invention, the spectral information of walnuts from different production places of Xinjiang within wave numberranges of 12000-4000 cm<-1> and 4000-400 cm<-1> is extracted through a near-infrared spectrum analyzer and a mid-infrared spectrum analyzer to construct a Xinjiang walnut production place distinguishing model.

Description

1. Technical field

[0001] The invention relates to a method for distinguishing Xinjiang walnut production areas based on infrared spectroscopy, and belongs to the technical field of rapid detection, monitoring and control of food quality and safety. 2. Background technology

[0002] As the most widely distributed nut food in the world, walnuts are called "four major dried fruits" together with almonds, cashew nuts and hazelnuts. Xinjiang is one of the origins of Chinese walnuts, and it is also the main origin of Chinese walnuts. By 2013, the walnut planting area in Xinjiang had exceeded 300,000 hectares, with an annual output of more than 300,000 tons. Xinjiang walnuts are mainly grown in southern Xinjiang, especially Hotan, Kashgar and Aksu. There are mainly varieties such as "Wen 185", "Zha 343", "Xinfeng" and "Xinxin 2". Walnut has become the most characteristic agricultural product resource in Xinjiang. However, with the development of trade and the intensification of ...
