Embodiment 1
[0032] Embodiment 1, the rapid detection method of betel nut moisture content based on near-infrared spectroscopy
[0033] The specific operation steps are as follows:
[0034] (1) Collecting samples and detecting moisture content in samples: collecting betel nut samples in different processing processes, divided into calibration sample set and verification sample set, and finally 768 samples were selected to form the calibration sample set, and 387 samples were selected as the verification sample set. The sample set covers the samples in the 10 processing steps of seed selection, cleaning, drying, hair, drying, surface incense, cutting, brine, drying and packaging in the production process;
[0035] According to the actual measured value of the moisture content in the sample measured by the direct drying method in GB5009.3-2010 "Determination of Moisture in Food", a reference value data set for the near-infrared model of the calibration sample set and the verification sample ...

The invention relates to a rapid detection method for areca-nut water content based on a near infrared spectrum analysis technology. The detection method comprises the following steps: obtaining the near infrared spectrum diagram information of a representative areca-nut sample under a set modeling condition, and utilizing a traditional standard physiochemical method to measure the water content of the sample; selecting a proper chemometric resolution method, and establishing a mathematic relation between the diagram information and the water content of the sample, namely a quantitative model; adopting a verified sample set to carry out verification assessment, completing model performance, and finally enabling the model to be used for measuring the water content of the sample to be measured. The detection method is simple, accurate and rapid in operation, the measurement of a single sample can be completed within 30 s, the practicability is higher, and the urgent need of areca-nut production and processing enterprises for real-time product quality control can be solved.
Description
technical field [0001] The invention belongs to the technical field of rapid detection of food quality and safety, and in particular relates to a method for rapid detection of water content in betel nuts based on near-infrared spectrum analysis technology. Background technique [0002] Areca nut trees are widely cultivated in tropical and subtropical regions, and are mainly distributed in Hainan Island, Taiwan, Yunnan, Guangxi, Guangdong and Fujian in China. Betel nut is one of the four major southern medicines in my country. It contains a variety of pharmacologically active ingredients, mainly including alkaloids, phenolic compounds, fatty oils, and various amino acids and minerals. Insect repellent and other effects. Betel nut is the main ingredient of Betel Quid (BQ), which is the fourth most widely used indulgence in the world after tobacco, alcohol and caffeine. It is estimated that there are about 600 million people chewing betel nuts in the world, and this number is ...
