    AKAZAKE (a traditional Japanese rice wine produced in the Kumamoto Prefecture) has a high sugar concentration and can be used for sweet seasoning instead of HONMIRIN (a sweet cooking rice wine). AKAZAKE and HONMIRIN were stored for 12 months; their pH, sugar content, and color value were measured monthly. After 6 months of storage, their amino acid content was measured by HPLC. Further, we evaluated their taste using a taste sensor system and performed a sensory evaluation. We analyzed the influence of storage at 5 and 25°C on the taste and flavor of AKAZAKE and HONMIRIN. The pH, color, and taste of AKAZAKE changed significantly at 25°C compared with 5°C. Therefore, we recommend that AKAZAKE be stored at temperatures lower than room temperature.

    To understand the multimodal effects of soft drink color and flavor on the predicted palatability and taste, we prepared six differently colored water in individual plastic bottles: yellow, orange, red, purple, blue, and green, by dissolving artificial colorants with mineral water. We also used four types of essence: lemon, apple, strawberry, and mint. Each essence was placed on a smelling-strip on the underside of the bottle cap. In the visual experiment, subjects observed one of the colored waters without any olfactory cues. In the olfactory experiment, they observed non-colored water and smelled the underside of the cap. In the visual-olfactory experiment, they observed one of the colored waters while smelling an essence. Subjects evaluated the predicted palatability, sweetness, sourness, and bitterness in each experiment. As a result, palatability was higher for the yellow color with lemon flavor, and red color with strawberry flavor. In addition, the contribution ratios of flavor to color were 1.24 for palatability, 4.61 for sweetness, 1.91 for sourness, and 1.98 for bitterness.
