Abstract

Red fruits’ oil contains 12,000 ppm carotenoid compounds and among them β-karoten was found as the major carotenoid compound. However, the application of red fruits’ oil as the food ingredient is rarely investigated due to its low solubility in aqua-phase, phenolic aroma and bitter aftertaste. Therefore , emulsification of red fruits’ oil in water (oil in water, o/w emulsion) using CMC (carboxymethyl cellulose) as the emulsifier and stabilizer agent considered as alternative to overcome those limitations. In the present work, the optimum concentration of red fruits’ oil emulsion added into Java tea-based functional drink increased the total carotenoid content, gave red color and might enhanced its antioxidant activity. The optimum formula was performed by Response Surface Methodology approach utilizing Design Expert 10.0.7® (DX10) Trial software whereas the emulsion concentration of red fruits’ oil as the variable factor. Red fruits’ oil emulsion which has been prepared from 20% red fruits’ oil and 1.50% CMC as emulsifier and stabilizer was having total carotenoid content of 72.93±1.33 ppm. The optimum concentration of red fruits’ oil emulsion added to Java-tea based functional drink was 5.86%. The addition of red fruits’ oil emulsion increased the total carotenoid content from 0.37±0.13 ppm to5.28±0.05 ppm. The results showed that red fruits’ oil emulsion could be used as red colorant agent in the functional drink while increasing the total carotenoid content, however, reduced the flavor sensory acceptance in high amount

Abstract

Tea is one of the beverages widely consumed due to its functional aspects, yet its applications remain limited primarily to brewing. Another product that has gained significant popularity among the community, especially school-age children, is bursting popping boba due to its explosive sensation in the mouth. Bursting popping boba is produced using the spherification technique, a molecular gastronomy component. It is commonly based on sugar or syrup solutions. One approach that can enhance tea product diversification is transforming it into bursting popping boba. However, tea-based bursting popping boba has yet to be widely recognized by the public, exceptionally high school students. Hence, there is a need for a workshop on the production of bursting popping boba. This workshop was held on November 4, 2022, at SMA Kristen Karunia Jakarta. The Community Service Program activity was successfully executed and received positive feedback from the high school students of SMA Kristen Karunia Jakarta, as indicated by the questionnaire results. Specifically, 97.5% of the participants found this activity beneficial and informative. In comparison, 92.5% expressed interest in participating in such activities again.
