[0036] 1. Using 3 batches of Huoxiang Zhengqi water from a certain manufacturer as the basic sample solution, the amount of ethanol in each sample solution determined by gas chromatography is ①43.2%, ②44.7%, ③45.2%.

[0037] 2. As Huoxiang Zhengqi Water requires ethanol in the range of 40%-50% in the Pharmacopoeia, by adding ethanol or water to 3 batches of samples, there are 35-55% of data points, a total of 20 data points.

[0038] 3. Substituting 20 modeling data points into OPUS quantitative software for automatic optimization. The software obtains the best band and measurement method, and builds the model.

[0039] 4. The obtained model was verified and tested on another 10 batches of Huoxiang Zhengqi water samples from the same manufacturer, and the predicted values ​​were obtained; at the same time, 10 batches of Huoxiang Zhengqi water were measured by gas chromatography, and the predicted values ​​and actual measurements were carried out. The value comparison shows that the d...

Abstract

The invention discloses a rapid food and drug detection method based on a near infrared technology. The method comprises the following steps: collecting a modeling detection sample, establishing a near infrared technology analysis model, debugging the model data, performing rapid field detection, drawing a conclusion and preserving the conclusion. According to the method disclosed by the invention, the rapid field detection is performed by utilizing a near infrared spectrum, and the information is simple and rich; nondestructive sampling is adopted, direct sample introduction is realized, the operation is simple, pretreatment of the sample is not needed, the sample is green and environmental-friendly, and the performance is reliable; only the detection amount of 0.1mg is needed, related consumables and maintenance cost are avoided, the operating cost and environmental protection risk are reduced, lots of manpower, material resources and financial resources are saved, actual problems such as long-term hidden grass-roots criminal activities, wide supervision range, large quantity and high difficulty are effectively solved, and the aim of guaranteeing the quality safety of foods and drugs is achieved.

Description

Technical field [0001] The invention belongs to the technical field of food and drug detection, and in particular relates to a fast food and drug detection method based on near infrared technology. Background technique [0002] Food and drug safety is related to the health and life safety of the broad masses of people, as well as to the healthy development of the economy and social stability. Food and drug safety issues involve people's livelihood and are one of the hot social issues that the people are most concerned about. In recent years, as market competition continues to intensify, food safety incidents such as the addition of Sudan red to food seasonings, the addition of trichlorfon to ham, the abuse of artificial colors in beverages, and the addition of melamine to dairy products, have occurred one after another, and even intensified, causing great harm , The impact is extremely bad, once caused the people to have a crisis of confidence in food; the phenomenon of low-limi...
