The effect of inoculum level ofLactobacillus curvatuson Nham fermentation was studied. Nham inoculated withL. curvatusat
10
4
(LC104) and 10
6
cfu/g (LC106) exhibited a higher rate of fermentation than naturally fermented Nham (control) as indicated by
greater rate of pH drop, lactic acid production, and changes in protein compositions. Based on the pH, the fermentation was
completed within 72, 48 and 36h for control, LC104, and LC106, respectively. Higher extent of proteolysis and lipolysis were
observed during fermentation of Nham inoculated with starter bacteria (Po0:05). Due to higher acid production rate and extent,
texture development of inoculated Nham was more rapid. Inoculated Nham exhibited higher TPA hardness and adhesiveness but
lower fracturability than naturally fermented Nham (Po0:05). In terms of acceptability, control and LC104 had higher ratings on
the overall liking than LC106 (Po0:05). However, LC104 was better accepted than control in terms of flavour, sourness, saltiness,
and texture. Unusual smell was detected only in Nham inoculated at 10
6
cfu/g. Based on physico-chemical properties and consumer
acceptability,L. curvatusis a potential starter for Nham fermentation. However, inoculation of L. curvatusat high level may cause
off-flavour in the product.
