Abstract

The invention discloses a method for nondestructive testing of the polyphenol content in waxberries based on a near-infrared hyperspectral technique. The method comprises the following steps of: collecting fresh waxberry samples of different varieties, performing spectrum scanning by using a near-infrared hyperspectral imaging system, and collecting 900-1700nm near-infrared hyperspectral images to obtain sample set spectra; testing the polyphenol content in the waxberry samples by a Folin-phenol method; and establishing a correcting model by applying a partial least square regression (PLSR) method to obtain an optimal prediction model of the polyphenol content in waxberries. By means of the near-infrared hyperspectral imaging technique, the polyphenol content in waxberries can be detected nondestructively, efficiently and quickly.

Description

technical field [0001] The invention relates to a method for nondestructively detecting polyphenol content based on near-infrared hyperspectral technology, in particular to a method for nondestructively detecting polyphenol content in red bayberry based on near-infrared hyperspectral technology. Background technique [0002] Red bayberry is a characteristic fruit of our country, and it is planted in a relatively large area in Zhejiang, Fujian, Guangdong and other provinces. Waxberry has high nutritional value, and the pulp is rich in carbohydrates, proteins, amino acids, organic acids, minerals, vitamins and polyphenols. "Compendium of Materia Medica" records that red bayberry "quenches thirst, and the five spoils, can wash the stomach, and relieve restlessness and bad breath." Modern biology and medicine have further proved that red bayberry has the effects of preventing constipation, antibacterial, and relieving loss of appetite. [0003] Myrica rubra polyphenols is the ...
