Abstract

The invention discloses a transmission spectrum non-destructive quantitative evaluation method of apple watercore, and belongs to the technical field of rapid evaluation of food quality. The transmission spectrum non-destructive quantitative evaluation method disclosed by the invention comprises the following steps: non-destructively obtaining entire optical information in an apple by using an near-infrared transmission spectrum collection system, collecting an image of a equatorial profile of the apple by using a camera, dividing the image by using an encirclement and suppression algorithm, calculating a watercore area and a sectional area of the apple, using the ratio of the area of a watercore section on a cross section to the area of the entire section as a quantitative prediction index, establishing a transmission spectrum non-destructive quantitative evaluation model of the apple watercore by using a multielement correction method after preprocessing an obtained near-infrared transmission spectrum, so as to achieve the non-destructive quantitative prediction of the apple watercore. According to the transmission spectrum non-destructive quantitative evaluation method disclosedby the invention, the degree of the apple watercore is quantitatively predicted by using the transmission spectrum technology, thereby avoiding the disadvantages of destructive sampling of a sectionvisualization method, and solving the technical problems of low recognition rate and blurred boundary of the watercore.

Description

technical field

[0001] The invention belongs to the technical field of fast and nondestructive evaluation of food quality, and in particular relates to a method for nondestructive quantitative evaluation of apple water core disease by transmission spectrum. Background technique

[0002] Apple water core disease occurs in the main apple producing areas in my country. Apple varieties such as Red Fuji, Marshal, and Qinguan are severely affected. Most of the disease occurs in the core and vascular bundles. It cannot be identified from the outside. The huge economic loss of the operator will directly affect the brand image and consumer confidence for consumers.

[0003] The traditional detection method of apple water core disease is to randomly select samples, and then slice them for visual judgment. This destructive sampling detection method is extremely wasteful, and it is not suitable for growers, processors and operators, and it is useless for product grading and evaluation. ...
