Total Titratable Acidity (TTA)
Total Titratable Acidity was determined using the method of Pearson as
reported by [7]. One gram of the each sample was put inside 100 ml
conical flask and 10 ml distilled was added; 1ml of phenolphthalein
indicator was then added to the mixture. It was titrated with 0.1 M NaOH
until pink colour appears the acidity was then calculated as lactic acid
(%).
\(\text{TTA}\ =\text{Titre}\ \text{value}\ \times 0.1M\ \text{NaOH}\ \times\text{acidic}\ \text{factor}\)
\((\text{Acidic}\ \text{factor}\ =0.009008\))
