SUBSTITUSI TEPUNG KEPALA IKAN LELE DUMBO (CLARIAS GARIEPINUS SP) UNTUK MENINGKATKAN KANDUNGAN KALSIUM CRACKERS
ABSTRACT: The using of fish
by-products has not been optimally developed in food processing. The objective
of this research was to study the using of catfish's head flour as a part of
material in formulating crackers to increase its calsium content. The method
for making this flour was based on thermal process using drum dryer. The
physical and chemical properties were analysed. Crackers was formulated by
using catfish's head flour with trial and error method. The formulations were
then F0 (0:100), F1 (7,5:92,5), F2 (12,5:87,5), F3 (17,5:82,5), and F4
(22,5:77,5). F1 and F2 crackers were chosen formulations based on organoleptic
test. The result of chemical analysis were respectively: moisture 2,4-3,3%
(wb), ash 3,7-4,97% (wb), protein 9,9-11,4% (wb), lipid 19,2-20,5% (wb),
carbohydrate 63,9-69,6% (wb), and energy 480-484 kkal (wb). F1 crackers
contained 0,3634% of calcium (wb) while F2 crackers contained 0,3147% of
calcium (wb). The phospor's content in F1 and F2 crackers were respectively:
0,2362% (wb) and 0,3147% (wb). The contribution of calcium content in crackers
were calculated based on RDA (Recommended Dietary Allowance) for children,
adolescents, and adults. F1 crackers fulfilled calcium’s RDA respectively :
25,8% for children; 15,5% for adolescents, and 19,3% for adults. F2 crackers fulfilled calcium’s RDA
respectively: 39,9% for children; 23,9% for adolescents, and 29,9% for adults.
The amount of crackers that should be consumed was at least as much 44
gram/day.
