Pemanfaatan Pati Kelapa Sawit Sebagai Bahan Baku Dekstrin
Abstract
The oil palm trunks become waste from the rejuvenation of the oil palm plantation. The extraction of the oil palm trunk yielded 4,7% of starch. The starch was extracted and characterized its physical and chemical properties and compared it to the commercial starches (sago and tapioca). The extracted starch was modified to be dextrin by enzymatic and acid hydrolysis. The oil palm starch contained lipid (0,37%), ash (0,68%), fiber (1,78%) which were higher than that of sago and tapioca. However, the amylosa content (28,67%) of the oil palm starch was lower. The gelatinization temperature of oil palm starch (770C) was similar with that of sago, but was higher than of tapioca. The whiteness degree of starch (83,02%) and the paste clarity (15,4%T) of the oil palm starch were lower than sago and tapioca. The α-amilase susceptibility of oil palm starch was lower than that tapioca and sago; however, the susceptibility of the oil palm starch on acid was almost similar with sago and tapioca. The dextrin quality of the oil palm starch, either from enzymatic or acid hydrolysis was lower than the tapioca; however, it was almost similar with the sago based on ash content, viscosity an solubility in cold water.
