PENGARUH KONSENTRASI NATRIUM ALGINAT SEBAGAI PENJERAT SEL Lactobacillus acidophilus FNCC 0051 DAN LAMA PENYIMPANAN TERHADAP JUMLAH SEL YANG TERLEPAS DAN KARAKTER CARRIER
Abstract: The aim of this
study is to know the effect of sodium alginate concentration in Lactobacillus
acidophilus FNCC 0051 entrapment, refrigeration storage (±5oC) period and
interaction of both factors on the number of released cells and carrier’s
character (UHT milk). The experimental design used was factorial RBD
(Randomized Block Design) design with two factors, sodium alginate
concentration (1%, 1,5%, 2%) and storage period (0,10, 20 days). The parameters
observed are the number of released cells (Total Plate Count / TPC), pH and
total lactic acid of the carrier (UHT milk). The obtained data are
statistically analyzed by ANOVA (Analysis of Variance) at α=5% and continued
with Duncan’s Real Difference Distance test (Duncan's Multiple Range Test) to
determine which level of the treatment that gives a significant differences.
Sodium alginate concentration and storage period had significant effect on the
number of released cells and carrier’s character (pH and total lactic acid of
UHT milk) and there is interaction between both factors. The lower level of
sodium alginate concentration increased the number of released cells, decreased
pH value and increased total lactic acid. During 20 days storage, the amount of
released cells and acidity of carrier increased than 0 and 10 days. Interaction
between both factors which give the less number of released cells (3,7948 log
cfu/ml) and carrier’s character changes (pH = 6,4767 and total lactic acid=
0,0741 %) is combination of 2% sodium alginate concentration in 0 days storage.
