RESULTS AND DISCUSSION
To make KL curry, the Thais must boil
the KL in water and they usually add sodium
chloride or eggplant into the water to reduce the
bitterness. Thus the study tried to determine the
effect of sodium chloride and eggplant on the KL
boiling process. With the first filtrate (Figure 2),
it was found that only the TSS values were
significantly different. The TSS of the first filtrate
of KL boiled in water had the lowest value while
the TSS of other treatments were higher and were
not significantly different because the added
sodium chloride and eggplant provided TSS also.
The acidity of the KL (Figure 2) was shown by
the low pH values of 3.61–3.69 which produced
the sour taste. The color of the first filtrate in the
three treatments was red-yellow with turbidity
(Figure 2).
For the second filtrate (Figure 3), it found
that only the TSS was significantly different, as
was the case with the first filtrate. However, the
TSS of all three treatments was lower than the TSS
