Abstract: Different process technology between potato granules and potato flakes were analyzed, and the chemistryperformance, physics performance, functionality of potato granules and potato flakes made from different process technologywere tested. The result shows that the starch leakage, relative viscosity, water retention, fat binding capacity, reducing sugarcontent of potato flakes were higher than that of potato granules, while the hydration speed of potato flakes was slower than thatof potato granules.

Key words: potato granules and flakes, process technology, quality testing
