英文摘要: Abstract(#br)This study compared the quality and moisture sorption properties of dried sweet potato prepared from three varieties (two yellow types and one purple type). Semi-dried sweet potato was subjected to a hot-pressing, which led to a final moisture content of 0.14–0.22 kg/kg solid (dry weight basis). The textural properties of the dried product depended on the sugar content of raw materials. In addition, the sugar content also influenced the MSI properties of the dried product. Based on the mathematical models, the GAB equation was revealed as the best model to explain the MSI properties of dried sweet potato. Among the varieties, Annou-beni (AB) showed the highest sugar content and would be the best variety from a taste point of view. Beni-haruka (BH) showed similar qualities to...
