Abstract/OtherAbstract:
The objectives of this study were to evaluate the influence of the addition of long-chain inulin as a fat replacer and prebiotic agent (20 g/L) and (or) probiotic Lactobacillus paracasei ssp. paracasei on the sensory profile and acceptance of yogurts, and to assess the influence of descriptive attributes on the sensory acceptance of the products. The addition of inulin to low-fat yogurt improved its brightness and firmness, which was similar to the full-fat yogurt. However, the use of long-chain inulin increased the separation of serum and no influence on creaminess was observed. Regarding the product's acceptability, the low-fat yogurt with added inulin presented similar acceptance compared with the full-fat yogurt. The addition of Lb. paracasei ssp. paracasei did not affect the sensory profile and acceptance of the low-fat yogurt. Using external preference mapping, it was possible to verify that the sensory acceptance was driven positively by the sweetness and creaminess and negatively driven by firmness (appearance and texture) and homogeneity (appearance). It was possible to formulate low-fat yogurts with added probiotics that presented similar sensory characteristics to those of full-fat yogurts, and this was due to the addition of the long-chain inulin as a fat replacer.
