Karakteristik Fisiko-Kimia Pati Sagu Termodifikasi Melalui Metode Ganda Fermentasi Dan Heat Moisture Treatment
ABSTRACT
Sago starch has limited functional properties due to its low
physicochemical characteristics and poor gelatinization at low temperatures,
resulting in a longer cooking time. To improve its physicochemical properties,
sago starch can be modified, one of which is through a dual modification method
combining fermentation and heat-moisture treatment (HMT). This study aimed
to obtain the best physicochemical properties of sago starch modified by a dual
process, namely fermentation and HMT. The research was conducted
experimentally using a completely randomized design with six treatments and
three replications. The treatments were FHMT1 (5% L. plantarum + HMT at
110°C), FHMT2 (5% L. plantarum + HMT at 120°C), FHMT3 (5% L. plantarum
+ HMT at 130°C), FHMT4 (5% L. casei + HMT at 110°C), FHMT5 (5% L. casei
+ HMT at 120°C), and FHMT6 (5% L. casei + HMT at 130°C). The results
showed that dual modification treatments significantly affect, indicated by an
increase in amylose content, water holding capacity (WHC), oil holding capacity
(OHC), and solubility, as well as a reduction in moisture content, swelling power,
and freeze–thaw stability. The selected treatment was FHMT6, which exhibits a
moisture content of 6.90%, amylose content of 26.52%, swelling power of 12.23
g/g, solubility of 14.25%, water holding capacity of 92.27%, oil holding capacity
of 101.02%, and freeze-thaw stability of 66.88%.
