Outline of Final Research Achievements

This study aimed to develop the comprehensive quality evaluation method of wines based on the concept of “optical tasting” that imitates the sensibility of sommeliers by combing the multi-band optical sensing methods. By combining the infrared spectroscopic analysis on characterizing wine (liquid phase) for "confirming the taste", infrared absorption spectral measurement / analysis on the volatile components of wine (gas phase) for "feeling the aroma" and the analysis on the color parameters of the image of wine in the glass for "confirming the appearance", it was experimentally found that the comprehensive characteristics of wine could be objectively and quantitatively evaluated.

Academic Significance and Societal Importance of the Research Achievements

複雑な製造プロセスを経て生産されるバイオ食品としてのワインの光センシング情報に基づいた包括的品質情報の定量化の可能性を見いだした点は,本研究の特色であるとともに学術的に意義のあることである。また,開発した手法は非破壊かつリアルタイムでの計測が可能なため,最終的な品質だけではなくその製造プロセスの動的挙動をリアルタイムで定量的に把握できる可能性があり,ワインなどのアルコール飲料の生産や製品開発において新たな道筋を開いたものといえる。
