青果物の非破壊による内部品質評価に関する研究 : トマトの表面色と糖度

Many reports which studied on optical methods of nondestructive quality evaluation of agricultural products were reported recently. and in these reports, optical evaluation of maturity, external damage and quality attributes was dealt with.
By the way, the method to detect inner sugar components in a fruit by the optical methods was not yet experimentally estabilshed. Accordingly, this study was concerned with the relationship between indexes of color and the sugar com ponents of mini tomatoes.
As the main experimental results, after harvesting of tomatoes, the surface colors of tomatoes were in a advanced stage with the lapse of times but the sugar components of these were stationary. The relationship between √<a^2+b^2> or a/b and the sugar components of tomatoes were linearities. from above this result, it is showed that there is the possible future approaches of quality evaluation by the surface color of tomatoes.
