Item Evaluation of Lactobacillus Coagulans in the design of coffee-based probiotic beverages by using different preparation methods(Universidade Federal de Lavras, 2024-06-13) Ormaza-Zapata, Angela María; Barona, neyder Rodríguez; Arango, Félix Octavio DíazThe purpose of the presented work was to assess the viability of microcapsules containing Bacillus coagulans. These microcapsules were produced through spray drying and employed two different combinations of wall materials. The evaluation was carried out within the context of creating coffee-based beverages using nine distinct preparation methods. Various characteristics of the microcapsules were measured, including solubility, wettability, hygroscopicity, moisture content, and water activity. Sensory analysis was used to determine the proportion of probiotic incorporation in the roasted and ground coffee. Moreover, the viability and count of probiotics were quantified in the nine preparations, both in cold and hot water. Among the preparation methods, the Chemex approach demonstrated enhanced viability when utilized for hot water preparation, while the Cold Tower method excelled in cold water scenarios. The outcomes of the study underscore the considerable potential of Bacillus coagulans in developing coffee-based probiotic beverages. These beverages exhibit noteworthy chemical, sensory, and functional stability.Item Sensorial profile, content, and antioxidant activity in coffee beverages prepared by direct contact methods(Editora UFLA, 2020) Ormaza-Zapata, Angela María; Díaz-Arango, Félix Octavio; Rojano, Benjamín AlbertoDirect content coffee preparation methods may be used as alternative ways to obtain coffee beverages with varied cup profiles. In this investigation the antioxidant metabolites, antioxidant activity, and cup profiles were determined for coffee drinks prepared using five different direct contact methods. The method that registered greatest antioxidant retention was Ibrik, followed by French press, and Toddy. Antioxidant capacity was proportional to antioxidant component retention in the preparations made. It is recommended that coffee be prepared via the Ibrik, French press, and Toddy methods for high acceptance levels, as well as for retention of bioactive components with antioxidant properties and abilities.
