Embodiment

[0029] A real-time rapid inspection method for irradiated food by optimizing sensing data and pattern recognition in an embodiment of the present invention, which specifically includes the following steps:

[0030] Step 1. Place the positive sample of the irradiated high-protein and high-carbohydrate food to be detected in the detection space. After the gas emitted by it fills the entire detection space and reaches equilibrium, extract the gas in the detection space for electronic nose testing. Detect and record the response value of each sensor of the electronic nose every second, and generate the corresponding response curve according to the recorded response value.

[0031] In this step, the detection space can be a headspace bottle. After placing the positive sample of the irradiated high-protein and high-carbohydrate food to be detected in the headspace bottle, let it stand at room temperature (25±1°C) for 15 minutes. Therefore, the gas emitted by it can fill the entire d...

Abstract

The invention belongs to the field of food identification and provides a real-time quick testing method of irradiated food through optimizing sensing data and mode recognition, aiming to overcome the defect that existing electronic noses are low in detection accuracy during irradiation dosage classification and identification of food rich in protein and carbohydrate. The method has the advantages that dimension reduction is performed on an electronic nose system, so that interference of unrelated and unimportant data on identification is lowered; the method is high in repeatability during identification of a same sample; the method is suitable for quick identification of irradiated food containing high protein and high carbohydrate.

Description

technical field [0001] The invention belongs to the field of food identification, in particular to the rapid identification of irradiated high-protein and high-carbohydrate foods by using an electronic nose. Background technique [0002] Food irradiation refers to the use of atomic energy rays to irradiate food materials, thereby killing insects and bacteria on food, which can effectively improve the hygiene, safety and quality of food. However, it is internationally required that the dose of irradiated food should be appropriate, especially the conventional safe radiation dose of 10KGy. In order to protect consumers' right to know and promote fair trade, including whether the exported food meets the requirements of the importing country, whether the imported food In order to meet the hygienic management requirements of irradiated food in my country, and whether relevant food companies will increase or decrease the irradiation dose at will, it is necessary for us to use a new...
