Evaluation of the acceptability of a filter infusion of germinated purple corn (Zea mays L), lemon verbena (Aloysia citrodora) and moringa (Moringa oleifera)

Abstract

The objective of this research work was to elaborate and evaluate the acceptability of a filter infusion of germinated purple cor n (Zea mays L.), lemon verbena (Aloysia citrodora) and moringa (Moringa oleifera); The investigation had four phases, the first , a market stud y, as a second phase, a design of the process, third phase, the elaboration process and finally, the validation and optimization of the pro d uct. Fo r the market study, the population was 425,367 inhabitants and the sample was made up of 375 citi zens of the city of Chimbote, Ancash-Peru. For the design of the process, a detailed process analysis diagram (DAP) was made. For the validation of the product, an experime ntal design of mixtures was used, with 10 formulations, evaluating attributes such a s smell, color, flavor and appearance of the product, selecting an optimal formulation based on said attributes; The optimized formulation underwent a physicochemical and microbiological evaluation. C oncluding tha t 98% of those surveyed would buy the product; In addition, the manufacturing process requires 47 activities (22 operations, 20 inspections, 4 transportation, 0 waiting, 1 storage);In addition, the optimal formulation for the filter was 45% germinated purple corn, 30 % lemon verbena and 25% moringa.
