KARAKTERISASI SIFAT KIMIA TEPUNG KACANG LAWA MERAH (Phaseolus vulgaris L.) DENGAN BEBERAPA PERLAKUAN PENDAHULUAN
Abstract
The objective of this study was to characterize the chemical properties of ‘lawa merah’ bean (Phaseolus vulgaris L.) with some pre-treatment. This study used a Complete Randomized Design with one factor which consisted of four treatment levels as follows: A0 (without pre-treatment), A1 (roasting for 20 minutes), A2 (boiling for 10 minutes) and A3 (roasting for 20 minutes and steaming for 30 minutes). The results showed that the best pre-treatment was A1 (roasting for 20 minutes), which produced ‘lawa merah’ bean flour with moisture content 7.81%, ash content of 2.92%, protein content of 26.75%, fat content of 2.15%, carbohydrate content of 5.92% and fiber content of 8.09%.
