Abstract

ABSTRACT
Daluga (Cyrtosperma merkusii Hassk) Schott is one type of plant tubers that have a high
carbohydrate content, but its use is limited because of limited tecnohologi owned by the public.
Analog Rice is one of the solutions can be developed either in terms of the use of a new food source or
to diversify food. The research objective is to get the right concentration of CMC in the manufacture
of analog rice flour daluga bulbs. The first phase of the treatment of the old flour soaking sliced
tubers daluga the pristine 1 % NaCl solution for 60 and 120 minutes. Further analysis of oxalic acid,
oxalic acid treatment followed pads low second stage of rice manufacturing are analog to the
treatment CMC concentration addition. Treatment A = (100% flour daluga : 0% CMC), B = (99.6%
flour daluga : 0.4% CMC), C = (99.2% flour daluga: 0.8% CMC), D = (98.8% flour daluga : CMC
1.2%), E = (98.4% flour daluga : 1.6% CMC). Organoleptic test results, treatment was continued
with an analysis of selected physical and chemical properties. Results for flour daluga an average of
0.35-0.52% oxalic acid content and chemical composition of the water content of 11.97%, ash content
of 2.4%, 0.89% fat content, protein content 1.11% and carbohydrates conten of 83, 65. Analog For
rice, the chosen treatment CMC concentrations are treatment B = (99.6% flour daluga: 0.4% CMC).
nalisis With the results of physical and chemical properties of the analog rice yield 53.52%, colors
rice 70% , 43%, 179.96% water absorption, rehydration time of 7 minutes, water content 7.88%, ash
content of 2.6%, 5.42% fat content, protein content 0.66%, and carbohydrates conten of 83, 44%.
