Resistant starch, fermented and symbiotic milkAbstract
The demand for healthy and nutritious food products is increasing worldwide, resulting in various researches in the field of dairy. The objective of this study was to develop three formulations of fermented milks with and without addition of probiotic and resistant starch (RS) as follows: F1 = standard formulation (without probiotic and prebiotic); F2 = Bifidobacterium ssp + 1.5% corn starch (containing 0.75% RS), and F3 = Bifidobacterium ssp + 3% corn starch (containing 1.5% RS). The products obtained were stored at 5 ° C and evaluated for viability of the probiotic bacteria and RS content during the 28 days of storage. Sensory acceptance tests and purchase intent were performed. The results showed that the viability of the probiotic fermented milk remained within the limit proposed by Brazilian law for foods with functional property claim, with values of 107 UFC.mL-1. Formulations with the addition of RS did not increase the viability of bifidobacteria. However, the use of RS in the formulations F1 and F2 meets the rules for functional property claim. The test showed that F1 and F2 do not differ significantly in relation to the attributes tested. The results demonstrate great potential for the production of synbiotic fermented milk.
