ABSTRACT
Taro (Colocasia esculenta (L.) Schott) is one of the tubers that are widely grown in
Indonesia. Taro tubers are usually used as food. To increase the quality value of taro tubers,
processing the taro tubers into flour by drying. Drying is the process of heat transfer from the
dryer and water diffusion (mass transfer) of the dried material. This study aims to determine
the effect of temperature and drying time on yield and chemical properties of taro root flour
(moisture, ash, carbohydrates and fat content). The process of making flour begins with
peeling taro, washing taro using water, slicing taro, soaking in salt solution (NaCl), soaking
in sodium metabisulfite solution (Na2S2O5), drying, crushing, sifting. Soaking in a solution of
sodium metabisulfite (Na2S2O5) with a solution concentration of 0 ppm, 500 ppm, 1000 ppm
and 1500 ppm was carried out to determine the effect of sodium metabisulfite concentration
on the color of the flour produced. The results showed that the sodium metabisulfite solution
with a concentration of 1500 ppm produced a brighter color. The drying process is carried
out at various drying temperatures of 50oC, 60oC, 70oC and the drying time is 6 hours, 7
hours, 8 hours. The results showed that the temperature and drying time had an effect on the
chemical properties of taro tuber flour. The yield average value obtained was 19.77% and
the best chemical properties test results of taro tuber flour were at 70 oC and 8 hours, namely
3.2% moisture content, 1.22% ash content, 6 carbohydrate content, 21% and fat content of
0.54%.
Keywords: characteristics, drying, yield, flour, taro tubers
