Product Development of Rehydration Milk Drinks for Athletes after Exercise (Organoleptic Assessment and Nutritional Content)

BACKGROUND: Lack of drinking causes dehydration. Dehydration conditions affect the muscle performance, muscle endurance, and muscle strength of athletes. AIM: The aim of the study was to study the organoleptic assessment of rehydration milk drink for athletes after exercise. METHODS: This was an experimental research design using completely randomized design. The beverage formulation consists of an avocado rehydration milk drink (ARMD), a guava rehydration milk drink (GRMD), and a guava and ARMD (GARMD). The organoleptic evaluation was carried out by athletes with a preference scale (hedonic) from 1 (very dislike) to 10 (very like) for color, odor, taste, texture, and overall. RESULTS: The organoleptic assessment of all parameters showed no differences between the variants of each treatment (p > 0.05). The highest mean values for all organoleptic parameters for each treatment were ARMD1 (mean value 7.16), GRMD1 (mean value 8.03), and GARMD1 (mean value 6.86). The overall mean value is determined to be the best product of each treatment. Of the three treatments, GRMD1 had a better overall organoleptic mean score compared to ARMD1 and GARMD1. The nutritional content of GRMD1/100 g contains energy of 67.69 kcal, 8.04% carbohydrates, 2.65% protein, 2.77% fat, 15.45 mg of omega-3 fatty acids, 7.99 mg Vitamin C, and 13.85% sugar. CONCLUSION: The overall organoleptic assessment of parameters showed no differences between the variants of each treatment. GRMD1 with the highest overall organoleptic score (8.03) contains energy of 67.69 kcal, 8.04% carbohydrates, 2.65% protein, 2.77% fat, 15.45 mg omega-3 fatty acids, 7.99 mg of Vitamin C, and 13.85% sugar per 100 g.
