Sensory evaluation of yogurt: The sensory evaluation
of yogurt produced from Lagenaria siceraria protein
isolates is depicted in Tables 2 and 3. All the yogurt
produced with Lagenaria siceraria variety 1 (LS1)
protein isolates are inferior to the control in all the
sensory parameters evaluated (Table 2). However
yogurt with LS1 protein isolates at 25% level of
substitution was rated significantly superior in taste to
other higher levels of substitution. Yogurt produced with
25% LS2 protein isolates show no significant difference
in taste from the control (Table 3), however it showed
noticeable difference in colour, aroma and overall
acceptability. Yogurt samples produced with LS2 protein
isolates at higher levels of substitution were inferior to
the control in all the sensory parameters. LS2 (Bottle
gourd seed) protein isolate may be useful in enhancing
the protein content of yogurt up to 25% level of
substitution.
