Description:
<jats:p>Centella asiatica is one of the traditional herbs found commonly in Malaysia. It has been
used as an important ingredient in many traditional medicine practices due to its
antioxidant and pharmacological properties. This study was done by adding three different
percentages of C. asiatica extracts (20%, 40% and 60%) in noodles. Sensory evaluation
involving appearance, colour, taste and aroma (affective test), physicochemical properties
(texture, pH and colour), antioxidant activity (DPPH, FRAP, TPC and TFC assays) and
nutritional composition on control noodle and herbal noodles enriched with C. asiatica
were conducted. For sensory test, control noodle is the most favorable followed by 60%
herbal noodle. There was a reduction in the firmness of cooked 20% and 60% herbal
noodles. The pH value of herbal noodles also decreased as the concentration of herbal
noodles increased due to the addition of C. asiatica. Colour analysis showed that the L*
values of all the samples were increased, a* values decreased which indicated strong green
colour among the herbal noodles while b* values showed the highest value for control
noodle. Antioxidant tests such as DPPH showed that 60% herbal noodle exhibited higher
free radical scavenging with a value of 49.200% as compared to control noodle
(16.027%). The same finding was observed for FRAP assay where 60% herbal noodle
displayed higher value (111.335 µg/mL) than control noodle (71.233 µg/mL). TFC of
60% herbal noodle also showed the highest value as compared to other noodles. However,
TPC of 40% herbal noodles had greater value as compared to 60% herbal noodle. A
decrease in the nutritional value of herbal noodle compared to control noodle was also
observed. In conclusion, herbal noodles enriched with C. asiatica showed promising
antioxidant potential which can be used in functional food applications</jats:p>
