| Abstract | The aim of this study was to determine the effect of two drying methods, greenhouse solar drier and oven drier, onqualities of Jerusalem artichoke (Helianthus tuberosus L.) tuber (JAT). The quality characteristics were determined in term ofphysical and chemical qualities as well as microbial safety in the final samples. The results showed that protein, fat, ash,carbohydrate and total fiber content were not significantly different between solar drying and oven drying (p>0.05). However,inulin, total phenolic content (TPC) and antioxidant activity (AOA) in solar dried JAT was significantly (p<0.05) higher thanoven dried sample. Moreover, the color of JAT powder produced by solar displayed brighter than oven drying. Both dryingmethods were effective to reduce water content in dried products and had the total plate count and total yeast & mold count withthe acceptable level. |
