Embodiment 1

[0039] 1. Materials and methods

[0040] 1. Sample

[0041] We collected three kinds of raisin samples from Xinjiang: Hongxiangfei, Mamiliti and Munage. All three types of raisin samples were harvested in 2020. Aromatic compounds in raisins evaporate when dried at higher temperatures. In order to avoid the influence of moisture differences in the samples on the spectral data, we stored the collected samples in a dry atmosphere for 2 weeks, and then stored each type of sample in a ziplock bag.

[0042] 2. Method

[0043] (1) Near-infrared spectroscopy measurement

Abstract

The invention relates to a raisin identification model and an establishment method thereof. The invention relates to a raisin identification model establishment method, which comprises: (1) carrying out near infrared spectrum measurement on the pericarp and the pulp of a raisin sample to obtain the spectrum data of the pericarp and the pulp; and (2) performing baseline correction on the spectral data of the peel and the pulp, performing feature extraction through PCA, performing feature fusion, and establishing a classification model to obtain the raisin identification model.

Description

technical field [0001] The invention specifically relates to a raisin identification model and a method for establishing the same. Background technique [0002] Raisins are rich in dietary fiber, vitamins, carotenoids and polyphenols. Studies have found that regular consumption of raisins can not only regulate blood pressure, anti-inflammation and prevent cardiovascular disease, but also improve intestinal flora, neuroprotection and improve spatial memory. At present, raisins are widely added to cereals, tea, and various snacks. In 2017 alone, the total global raisin production has reached 1.22 million tons. Among them, the output of Chinese raisins accounted for 190,000 tons, ranking third. In addition, the varieties of grapes are very diverse. Different varieties of raisins have different tastes, nutritional properties and commercial value. At present, fast and accurate identification of different types of raisins is also one of the main challenges in quality grading ...
