A study was conducted to develop high
fibre biscuit using locally available raw materials
specially incorporating palmyrah tuber flour.
Biscuit with high fibre was developed according
to two factor factorial design using three variables
namely palmyrah tuber flour(40g,48g),
Altemantherasessilis stem powder(5g,7.5g) and
red rice flour(20g,24g) at two levels (low and high).
The other ingredients, such as sesame seeds
(12g), sugar (14g), salt (0.5g), ammonium bi
carbonate (0.25g), sodium bi carbonate (0.2g),
emulsifiers (16g), w ater (7.5ml) and milk powder
(1g) were kept constant for all eight treatment
combination. The bitter compound (Fiabelliferin)
of palmyrah tuber flour was removed by soaking it
in distilled water for one hour trice. Biscuit dough
relevant to eight treatment combination was
prepared and baked using hot air oven. Then
prepared biscuits were subjected to sensory
evaluation in order to select best treatment
combination according to sensory attributes
crispiness, appearance, mouth feel, flavor,
texture, colour and overall acceptability. Moisture
content, Fat, Protein, Dietary fibre, Total sugar,
Carbohydrate, Ash, Total Energy (MJ), Calcium,
Copper, Magnesium, Manganese and Iron of these
two treatment combination were analyzed.
Sensory evaluation results revealed that two
best treatment combinations were palmyrah tuber
flour: Altemantherasessilis stem pow der red rice
flour; 40:7.5:20 and 48:5:20 respectively. Moisture
content, Fat, Protein, Dietary fibre, Total sugar,
Carbohydrate, Ash, Total Energy (MJ), Calcium,
Copper, Magnesium, Manganese and Iron of these
two treatments were 1.44±0.19%, 21.89±0.18%,
7.91%, 10.51%, 3.02%, 64.79%, 0.0210.01%,
20.9610.14%, 0.34mg/100g ,0.11mg/100g,
1.50mg/100g, 0.01mg/100g, 0.09mg/100g and
1.4810.74%, 21.8910.16%, 8.03%, 10.30%, 3.34%,
64.72%, 0.0210.03%, 20.8210.05%, 0.33mg/100g,
0.10mg/100g, 1.53mg/100g, 0.01mg/100g,
0.06mg/100g respectively. Shelf life test revealed
these two biscuit products can be stored in triple
laminate pouches (metaiized polypropylene) for
more than five months.
