Probiotics are living micro-organisms which impart certain health benefits like anti-oxidant, anti-hypertensive, immune-modulatory, opioid, anti-inflammatory, anti-microbial and consumer related inherit nutrition with the utilization in recommended quantity. The study aimed to determine the effect of Lactobacillus acidophilus, Bifidobacterium bifidum and Lactobacillus helveticas and their adjuncts on sensory attributes of cheddar cheese. The cheddar cheese having commercially available mesophilic starter cultures and with probiotics strains were prepared and assessed for acetic acid production, proteolysis and descriptive sensory analysis. The probiotics adjuncts Lb. acidophilus + Bifidobacterium bifidum (La + Bb) and Lb. acidophilus + Bifidobacterium bifidum + Lb. helveticus (La + Bb + Lh) showed remarkable results in production of acetic acid 489.33 (ppm) and as compared to control respectively. Among probiotic strains, the probiotic strain Lactobacillus helveticas showed the highest water-soluble nitrogen as 28.50 (%) and free amino acid 5220 µg/g. non-significant effect was observed for overall acceptability for control and probiotic adjuncts. Higher rates of organic acids and proteolysis was observed in probiotic adjuncts as compared to control samples. The current study reveals that the addition of probiotics adjuncts to cheddar cheese does not affects its overall acceptability.
