Determination of The Potential Use of Exopolysaccharide-Producing Streptococcus salivarus ssp. thermophilus and Lactobacillus delbrueckii ssp. bulgaricus in Yogurt
Abstract
In this study exopolysaccharide production
quantities of 88 Streptococcus
thermophilus and 28 Lactobacillus bulgaricus bacteria were investigated. Chemical, physical and
sensory properties of yogurt in which added the combination of the highest and
the lowest exopolysaccharide producing bacteria were determined. In all 9
yogurt samples titration acidity, pH, acetaldehyde and lactate production,
serum separation, viscosity and sensory evaluation results were investigated.
In the yogurt samples examined, acidity in terms of lactic acid (%), pH,
acetaldehyde, lactate, syneresis and viscosity values were found in the range of
0.63-1.055 %, 3.82-4.46, 20.45- 33.63 mg kg-1, 50.41-144.56 mg kg-1
9.3-10.6 mL, 5339-9280 cP, respectively. Sensory properties of yogurts produced
with the highest exopolysaccharide producing bacteria combination were most
preferred by the panel group.
