6. Chemical compositions were determined using : Moisture content (AOAC
1990) using vacuum drying oven at 70 °C ; Sulphur dioxide by modified
Rankine method ; Sugar content by 6 hour extraction with 80% ethanol,
filtered and measured sugar content with HPLC ; Starch content by Lane-
Eynon method ; Total soluble solid by blending one part of the pulp with 3
parts of water, centrifuged and read the soluble solid with a hand
refractometer ; Titrable acidity by titration of blended pulp with 0.1 N
sodium hydroxide using pH meter to indicate the end point.
7. Sensory evaluation : Hedonic scale was used to obtain acceptability of
the storage pulp by 15 panelists every week for 4 weeks.
8. Microbial determination for both packing facilities and storage of packed
urian pulp : Measurements with swab tests were used for microbial
contaminants during packing. Keeping quality of the pulp was evaluated for
microbial characteristics of total viable count ; Yeast & Mould ; Escherichia
coli ; Salmonella spp. ; Staphylococcus aureus ; Clostridium perfringens
and Bacillus cereus every week for 4 weeks.
