Abstract

The purpose of this study is to examine and evaluate the dried garlic quality throughout color and chemical compounds changes that caused by using different designs of direct solar dehydrators. The parameters were source of ventilation, roof shape and type of covering material. The parameters that evaluated in this study were type of ventilation, various covering material and nature of dehydrator's roof. The measurements which considered in this study were solar radiation incident on the dehydrator roof, solar radiation inside dehydrator, outside air temperature, inside air temperature, outside relative humidity, inside relative humidity, some color indicators such as whitening index (WI) and browning index (BI) and also, some chemical tests such as antioxidants and optical index. The results showed that the highest value of whitening index (WI) was 42.52 and 49.71 before and after storage and the lowest value of browning index (BI) was 94.49 and 76.87 before and after storage in dehydrator that covered with a thin white polyethylene cover and constructed shape as a gabled-even-span roof with forced-air convection type (WSA).In addition, maximum color change (ΔE) was 64.05 detected at dehydrator that covered with a thin blue polyethylene and constructed as a flat roof cover with forced-air convection type (BFA)while the minimum was 35.21 at dehydrator (WSA).The study recommended using the thin white polyethylene cover and constructed shape as a gabled-even-span roof with forced-air convection type (WSA)to obtain the best quality of dried garlic.
