| description | Cassava flour derived from the cassava crushed dried and sieved to 80 mesh.
Cassava flour generally have less favorable physicochemical properties when
compared with wheat or wheat flour to used as a raw material for making products.
To improve the physicochemical properties of cassava flour and starch, oxidation
process can be either physical or chemical. Chemical oxidation with oxidizing, which
in this study used hydrogen peroxide ( H2O2 ) with variation of concentration, while
the physical oxidation using UV-C light irradiation and using a rotating tumbler to
equalize exposure flour to UV-C light. The purpose of this study was to determine
which combination of treatment variations that produce the volume of development
best by comparing it with mocaf flour and cassava natural flour (native) .
Oxidation process in this study using the acidification of cassava flour with
the addition of lactic acid 1 % (w/w), the variation of irradiation with UV-C light
treatment in a tumbler, variations in the concentration of hydrogen peroxide, and
variations time of irradiation. The study design used was a completely randomized
factorial design. Parameters observed include baking expansion, carbonyl and
carboxyl numbers, amylose content, swelling power, solubility, whiteness
(brightness), and FTIR .
The results showed the presence of the oxidation process increases the baking
expansion, carbonyl and carboxyl numbers, amylose content, solubility , swelling
power and whiteness. Results baking expansion the most optimal is on irradiation
with UV- C lamp 20 watts, hydrogen peroxide concentration of 1.5 % and time of
radiation for 10 minutes 325,01% . |
