Deskripsi

The parameters of processing instant water chestnut was optimized with quality score and dehydration rate as indexes.The results showed that the sucrose concentration in impregnating solution was 15%,the ratio of water chestnut to impregnating solution was 1∶12 g/mL,impregnated for 9 h,dried at 60 ℃for 2 h.The products instant water chestnuttasted sweet and crisp with light yellow surface,the quality score was 95.6 and dehydration rate was 10.5%.The floating range of the color difference was less than 2.5 and lustre value was 81.05 after storage for 60 days,the color and lustre of instant water chestnutwas basically stable.
