Shape and size grading of apple fruit (cv. Fuji) based on geometrical properties

摘要

Fruit shape and size are the most important quality parameters for evaluation by consumer performance. Also misshapen fruits are usually rejected according to grading standards of fruit. This research was conducted to determine quantitative assortment and grading algorithm for apple shape and size. To reach objective and reproducible results, some Physical characteristics of apple (Fuji variety) such as mass and outer dimensions (length and width) were measured and an evaluation based on mass and outer dimensions was proposed. Results of the study showed that mass and aspect ratio (length to width ratio) of apple can be used successfully to grade apple shape and size.
