Abstract

The invention provides an apple soluble solid near-infrared detection part compensation method and system. The method includes the steps an absorbancy spectrum of the preset portion of an apple is obtained; the soluble solid content of the preset portion of the apple is obtained; according to the absorbancy spectrum and the soluble solid content, a characteristic wavelength screening algorithm is applied to select characteristic wavelengths related to the apple soluble solid content in a full-wave band spectral range, and an apple soluble solid near-infrared detection model is set up. Spectral information of multiple portions of the apple is fused, the characteristic wavelength screening algorithm is combined, the apple soluble solid near-infrared detection model is set up, the influence on the apple soluble solid near-infrared detection model by changes of spectrum detection is overcome, the stability of the model is improved, and a theoretical basis is laid for portable detection and online detection of apple soluble solid in practical production.

Description

technical field [0001] The invention relates to the field of apple quality detection, in particular to a compensation method and system for near-infrared detection parts of apple soluble solids. Background technique [0002] Soluble solids refer to the general term of all compounds dissolved in water in liquid or fluid food, including sugars, acids, vitamins, minerals, etc. The soluble solids content of apples is an important index to measure the internal quality of apples, and it is also a determinant factor affecting consumers' willingness to purchase. [0003] At present, near-infrared spectroscopy has been widely used in the detection of apple soluble solids due to its fast and non-destructive advantages. However, the stability of the model is often affected by factors such as temperature changes of apples, production areas, varieties, and seasonal differences. In addition, the distribution of soluble solids content on the surface of apples was not uniform, and its dis...
