    Obtención de una bebida láctea fermentada a partir de cepas probióticas aisladas de residuos de caña de azúcar (Saccharum officinarum L) y yuca (Manihot esculenta)

    The food industry has used lactic acid bacteria (LAB) for the production of a number of fermented dairy products; however, not all species used are considered probiotics. Therefore, the objective of the study was to demonstrate the viability of 10 probiotic strains obtained from natural residues of sugar cane (Saccharum officinarum L) and cassava (Manihot esculenta) for the production of fermented milk beverages, using physicochemical techniques such as pH and titratable acidity subject to the NTE-INEN 2395 standard, obtaining results ranging from 4.9 to 6.5 for pH and acidity from 0.37 to 0.92, values that were defined according to the behavior and activity of each of the 10 strains treated in the research. Fermentation was monitored for 12 h. In addition, bacterial growth was analyzed by counting the CFU/g in each sample collected during fermentation. The fermented beverages that visually presented the best characteristics were evaluated using sensory analysis. Of the 10 strains, four generated a beverage suitable for human consumption by possessing physicochemical, microbiological, and sensory characteristics similar to those of a commercial product. The use of new probiotic strains capable of generating fermented milk beverages opens up an alternative for probiotic consumption, allowing consumers access to a variety of probiotics with beneficial properties. Thus, the creation and distribution of functional products obtained from probiotic strains derived from natural residues is allowed.

    Desarrollo de una mezcla para bebida instantánea en base a harina pre-cocida de achira (Canna indica) enriquecida con probióticos (Lactobacillus plantarum, Lactobacillus rhamnosus y Lactobacillus casei)
    (Universidad Técnica de Ambato. Facultad de Ciencia e Ingeniería en Alimentos y Biotecnología. Carrera de Alimentos, 2023-09) Albán Rodríguez, Juan Gabriel; Flores Huilcapi, Ana Gabriela
    Starch and flour are obtained from achira tubers, as starch is easily digested, and flour is used in the partial replacement of wheat to make bread and cookies. Probiotics are live microorganisms that are administered to a host in adequate amounts to generate health benefits in relation to the intestinal flora. For this reason, a natural drink based on achira flour enriched with probiotics has been created, which at the same time provides health benefits as it is a functional product. Microorganism count and sensory analysis were performed for the 4 formulations studied, whose final results indicated that the formulation containing 6.49 percent of achira flour, 12 percent of probiotics, 0.01 percent of xanthan gum and 1, 5 percent sugar was the most accepted, with an ash value of 0.218 percent, protein 0.267 percent, moisture 90.8 percent, pH 5.47, acidity 0.066 percent citric acid, viscosity 1419 milliPascals per second, and 5.9 Brix degree. The content of viable microorganisms in the final product was 2 per 10 raised to the colony-forming unit per milliliter, so it can be said that the product can be considered a probiotic food because it meets the parameters established in the OMS regulations, in addition to being a functional product.
