Improvement of The Near Infrared Imaging Spectroscopy on Melons using the Compensation for Intensity Fluctuation and MSC methods

摘要

A new method to clarify unevenness of the sugar content distribution within fruits is desired because it will be a great help in improving the accuracy of sweetness sensor in automated sorting operations. It is also expected that applications of this method to other products and components will bring valuable information not only for agricultural fields, but also for biology, medical science and so on. Sugiyama (1999) had succeeded to visualize the distribution of the sugar content on the surface of a half-cut green fresh melon. However, this method cannot be applied to red flesh melons because it depends on information of the absorption band of chlorophyll (676 nm). which is affected by the color of the fresh. The objective of this study was to develop the universal visualization method depends on the absorption band of sugar, which can be applied to various kinds of melons and other fruits.
