Elaboración de kéfir de agua proteinizado con amaranto (Amaranthus caudatus L.) y saborizado con melocotón (Pronus persica).

Abstract

The objective of this study was to produce and test different levels of amaranth flour in order to provide protein and flavor to water kefir that according to previous studies has these deficiencies, for this, a submerged fermentation with kefir granules was performed (Hetero fermentative consortium of lactic acid, acetic and yeasts bacteria). As substrate panela dissolved in purified water was used, which was deposited in a glass jar and left for 72 hours in fermentation, then levels of 2, 4 and 6% of amaranth flour and the constant value of 10% of peach were applied. For the statistical analysis, an ADEVA was applied with the separation of means according to Tukey (p>0.05). The physicochemical results indicated that the addition of amaranth flour generates significant differences between treatments, with regard to the microbiological results it was determined that the presence of lactic acid bacteria and yeasts are greater than 〖1x10〗^6 UFC/ml so it is considered a probiotic drink, no coliforms present. The sensory results suggest a greater reception to T1 with ratings of 4 that corresponds to moderately liked. It is concluded that the addition of amaranth flour gives a protein contribution to the drink, the addition of peach improves its flavor and the microorganisms constitute it as a probiotic. Its production and consumption is recommended.
