There are abundant of Averrhoa bilimbi fruits in Malaysia and become underutilized. This<br />

study encompasses the effect of Averrhoa bilimbi paste and the combination of different<br />

percentage of thickening agents (corn starch and xanthan gum) in different formulation.<br />

The ratio in percentage of corn starch and xanthan gum are 100%:0%, 70%:30%,<br />

50%:50%, 30%:70% and 0%:100%. The fresh Averrhoa bilimbi is first processed to<br />

produce Averhoa bilimbi paste to be used as ingredient in the sweet sour sauce. Different<br />

percentage of thickening agents (corn starch and xanthan gum) are using to evaluate the<br />

properties of the sweet sour sauce produced. The properties are measure by<br />

physicochemical analyses which are involved proximate value, viscosity, pH, brix,<br />

titratable acidity and color. The sauce then analyze for its sensory acceptability and shelf<br />

life. Different properties of thickening agents will produce different properties of sweet<br />

sour sauce.<br />
