KEYWORDS: Buttermilk, soluble fibre, partially hydrolysed guar gum, fortification, sensory.

ABSTRACT: Buttermilk has a potential to become a daily diet drink at global level due to its high nutritive value and ease of production process. In present study, novel buttermilk beverage was developed using fibre fortification. Acidity, pH, viscosity, whey separation and sensory properties were studied. Fortification with fibre (1-5%) showed non-significant changes in buttermilk acidity and pH. Phase separation was lowest and viscosity was highest in buttermilk sample with 5% fibre. Buttermilk samples were also evaluated for their sensory characteristics including color and appearance, body and mouthfeel, flavor and overall acceptability. Samples with 4% fibre level obtained the highest scores in the sensory evaluation. The viscosity of the buttermilk samples increased proportionally with the levels of fibre fortification. Soluble dietary fibre fortification at 4% level in buttermilk improved nutritive, physicochemical and desirable sensory characteristics.
