| Outline of Final Research Achievements |
Dielectric spectra, water activity and frozen water content for 10-40% of six sugar solutions and six sugars mixed with gelatin were measured. Drying process of foods was experimentally investigated in the following topics: 1) superheated steam drying of frozen pizza dough, 2) drying process of green tea leaves after high hydrostatic pressure treatment, and 3) quantitative analysis for cacaopolyphenol content contained in cacao beans produced in different countries and regions. Although many challenges still remain towards the development of non-destructive online measurement system of drying process due to the budgetary constraints, fundamental experimental data of food drying process were sufficiently obtained.
