Abstract

Most energy gels in the market are mainly made up of maltodextrin which may impose health disadvantage to individuals with health condition. This project thus aims to develop jujube matcha energy gel with improved nutritional composition; and to study the effect of consuming jujube matcha energy gel on physical endurance performance. Jujube fruits or red dates contain relatively high natural carbohydrate were chosen as the base ingredient for the energy gel. Some evidences showed that antioxidants had beneficial effects on improving physical activities by reducing the oxidative stress and muscle fatigue during endurance exercise. Both matcha powder and jujube fruits are known to contain high levels of antioxidant activity. Thus, the addition of these ingredients was to increase the antioxidant activity of jujube matcha energy gel. Proximate analysis, physicochemical properties analysis and sensory evaluation of jujube matcha energy gel were conducted. Jujube matcha energy gel contained 72.44 % of moisture content, 16.30% of carbohydrate, 1.33% of fat, 7.72% of protein, 2.21% of ash, 8.83% of dietary fiber, 516mg /100g of potassium and 86 mg/100g of sodium. Jujube matcha energy gel exhibited a significantly higher free radical scavenging activity of 83.26%, ferric reducing antioxidant power (FRAP) of 49.21 mg FE/g, TPC content of 29.36 mg GAE/g and TFC content of 7.54 mg CE/g when compared to the commercial energy gel. The jujube matcha energy gel scored a sensory acceptance index of 77% using a 9-point hedonic scale (N=50). A 20-meter beep test was carried out to study the effect of consuming jujube matcha energy gel on physical performance. Subjects were found to endure longer after consuming jujube matcha energy gel with 18.73% improvement on time to exhaustion. In conclusion, jujube matcha energy gel with better nutritional composition could be a potential alternative for commercial energy gel.
