For this purpose, natural components have been used to help obtain a nutritious and sensoryally acceptable product. This research work determines the effect that the infusion time and temperature causes on the concentration of tannins in a new beverage lavender drink, for this purpose the design and development of the product has been used lavender as a natural raw material and main for the high antioxidant content and relaxing properties, an Experimental Design of 9 treatments and 27 repetition was used for tannin determination and the theoretical calculation of the nutrition table, labelling project and graphic system was performed. To obtain the lavender drink, a productive and controlled process was applied based on the elaborate flowchart, the method used is UV spectrophotometry developed by the Laboratory of the University of the Americas, a Completely Random Design was performed to identify significant differences between treatments, the influence of the factors that varied in each treatment was subsequently supported by a 3n Factorial Design and to meet the requirements of nutritional table, label and graphic system was applied the INEN 1334-2 Standards: 2011 and INEN 022: 2014. The results show a sensory-appropriate product at a cost of USD 0.48 cents of production, regarding the tannin content there are significant differences between treatments; the best treatment is 5 corresponding to 85 degree C and 6 minutes (358,717 mg L) and the treatment with the least amount of tannins is 9 at 60 degrees C per 3 min (232,346 mg L), and the factor that needs to be more controlled is the temperature, the finish product of 240 ml has 84 calories, 22g carbohydrates, 22 g sugars and 0.07 mg vitamin C, with a life span of 30 days under normal conditions and categorizing it within a graphic system high in sugar and low in fat and salt. |
