Bitterness o f Un-bo iledpalmyrah tuber flour is a hindrance for the development o f palmyrah tuber flour products. A
study was conducted to determine an appropriate method to remove the bitterness o f un-bo iled palmyrah tuber flour.
The debittering process was performed using both hard water and distilled water in three different treatments. During
the first treatment, the palmyrah tuber flour was soaked in hard water for three hours and filtered. The water was
replaced once every hour. In the second treatment, the palmyrah tuber flour was soaked in distilled water for one hour
and filtered. In the third treatment, the palmyrah tuber flour was soaked in distilled water for three hours and filtered.
Die water was replaced once every hour. The filtered flour was then dried using an oven. The dried flour was divided
into two portions. l Og o f dried flour from one o f the portion was dissolved in 200ml water. Both dried and liquid
samples were then subjected to sensory evaluation to check the level o f bitterness. Both the dried and liquid samples
gave strong bitterness, little bitterness and no bitterness for first, second and third treatments respectively. Removal
o f flabelliferin was seen by the change o f colour o f the water
