Outline of Final Research Achievements

In this study, we estimated the degree of red coloration in "Kurenai-no-Yume" apple flesh by interactance spectroscopy and analyzed the effect of optical path length between light source and detector on the estimation accuracy.

The PLS statistical analyses show the optical path length of 0-3 mm is effective to detect the degree of red coloration at 0-12 mm flesh depth from apple skin and that of 4-7 mm is more useful to predict the flesh coloration at 17-22 mm depth.

Academic Significance and Societal Importance of the Research Achievements

経済発展などに伴い,世界中の消費者からの農産物の安全・安心とともにその品質に対する要求は益々多様化,厳格化している。それに応えるために,今まで以上に海外産と差別化できる高品質の農産物を生産できる管理技術の向上が急務とされている。
本研究で得られたインタラクタンス分光計測による深さ別の果実内部着色度についての基礎知見は,現在の農産物内部品質評価システムをより高精度に改良・発展させるための方向性の一つを示すことができた。
