[Sovereign Items] 1. A method for establishing a component correlation model for glass bottled foods, which is characterized by the following steps: Step 1: The standard analysis method is used to measure the content of each component in one or more standard bottled food samples respectively to obtain a standard. The component content values; the one or more standard bottled food samples are representative samples in which the component contents are different and the values ​​thereof are distributed; Step 2: The representative samples of step 1 are collected by a near-infrared spectroscopy apparatus by means of a diffuse reflection method. Near-infrared spectroscopy; Step 3: Elimination of near-infrared spectroscopy by mathematical operations to eliminate the influence of the bottle body on the near-infrared spectrum; Step 4: Extracting the near-infrared spectrum collected from step 2 by mathematical operations again Represents the characteristic data of each component in the sample spectrum; Step 5: Establish the correlation model between the standard component content values ​​of each component in the representative sample and the feature data of each corresponding component in the spectrum, for different types of food in the same bottle. The respective models for each type of food were established.

ã€Abstracts】 The present invention relates to a method for establishing a component correlation model for glass bottled foods and a food detection method. The method for establishing an association model includes measuring the contents of various components in a sample using a standard analysis method, and collecting their near infrared light through diffuse reflection. Spectral; Elimination of the effect of the bottle body on the collected near-infrared spectrum by mathematical operations; Extraction of the feature data of each component in the spectrum by mathematical operations; The establishment of the characteristic data of each component's content value and each corresponding component in the spectrum The correlation model between food and food detection methods includes the collection of near-infrared spectroscopy of the bottled foods being tested, elimination of the effect of bottle reflections on the near-infrared spectrum, elimination of the scattering effect of the bottled foods being tested, and prediction of the measured bottled foods according to the association model. The content of each ingredient. The invention can realize rapid, accurate and non-damage detection of various components in the bottled fermented bean curd without destroying the bottle, which can save the time of detection and improve the detection efficiency.
