Title Alternative
Quality Evaluation by Non-Destructive Measurement in Fruit
Author
Mohri, Kentaro
Abstract
It is important to classify fruits according to their quality in post harvest, but many kinds of fruit are classified only by their size or shape. In this paper, an investigation to evaluate maturity useing the skin color of fruit and to predict the sugar content of a fruit directly by near-infrared spectroscopy is describbed. The following results were obtained, 1.It was established that the fruit maturity can be found by expressing the changes of skin color as the values of L, a and b in Lab color system. 2.It was clear that the sugar content of a fruit can be predicted with a calibration equipment to be determined by multiple regressions analysis from the relation between the absorption of light rays which related the sugar in the wavelrngth of near infrared band and the sugar content of fruit which was measured by destructive method.
