บทคัดย่อ (EN): The objective of this research was to analyze the physicochemical, microbiological, and sensory characteristics of Gac and passion fruits enriched-probiotic yogurt. The products were formulated by different formulations of skim milk powder and sucrose. The research was designed as Complete Randomized Design (CRD) with 2 treatments, which were consisted of skim milk powder (4%, 6% and 8%) and sucrose (4%, 6% and 8%) concentration. Parameters were titrable acidity, pH, texture, syneresis, viscosity, colour, microbiological characteristics, and sensory test. The results showed that the concentration of skim milk powder and sucrose significantly affected (P<0.05) the titrable acidity, pH, syneresis, viscosity, texture (hardness and cohesiveness), colour (L* and a*) and total yogurt bacteria counts. The yogurt that was formulated by 8% skim milk powder and 4%, 6%, or 8% sucrose (A3B1, A3B2, and A3B3) resulted in relatively good quality yogurt based on its physicochemical and microbiological properties. However, sensory analysis showed that the treatment of A3B2 (skim milk powder 8% and sucrose 6%) resulted in the most preferred yogurt based on the average of hedonic score. It had the characteristics of 13.23% for the titrable acidity, 3.43 for pH value, 2.76 N for hardness, 0.35 for cohesiveness, 3.86 for syneresis, 221.74 mPas for viscosity, 7.2 log CFU/g of yogurt bacteria counts and 6.6 log CFU/g of Lactobacillus acidophilus counts.
