YELLOW SWEET POTATO STARCH HYDROLYSIS INTO GLUCOSE ENZYMATICALLY
ABSTRACT: Glucose is
a monosaccharide found
in many fruits,
and plants obtained
through a process
using enzyme hydrolysis of
starch saccharide. Sweet
potato starch Hydrolisis
run with three
neck flask equipped
with a stirrer. In Liquifikasi
stage, three"neck flask is inserted into the starch solution which has
been set temperature and the pH was added HCI and in the heat, then added
α"amylase enzyme in a certain time. Saccharification second stage,
where the results
liquification cooled, set
the temperature and
pH on certain
conditions. Then added enzyme
giukoamilase by volume according to the specified variable, and incubated at a
given time. At a certain time interval
was taken a
few examples of
the analyzed samples
will be analyzed
glucose levels Process behavior
observed in this
study were changes
in temperature, hydrolysis
time and the
addition of enzymes, the best
hydrolysis results obtained at 60 ° C, pH 4.5 and the addition of 0.7 ml of
glucoamylase and time hydrolysis 5
days with glucose
levels reaching 5
, 65% and
conversion yield of
66.8% and 22.59%.
