Pengaruh Perbandingan Konsentrasi Sari Wortel (Daucus carota L.) dengan Sari Nanas (Ananas comosus) Serta Lama Penyimpanan Terhadap Mutu Sirup Wortel-Nanas

Abstract

The goal of this study was to ascertain the impact of storage duration and carrot extract and pineapple extract concentration ratios on the quality of the syrup. This study used a factorial Completely Randomized (CRD) method with 2 factors, namely the ratio of carrots to pineapple (80%:20%, 50%:50%, 20%:80%) and storage time (7, 14, 21, and 28 day). Parameters analyzed were total dissolved solids, total microbes, vitamin C content, total acid, total sugar, pH value, viscosity, color index, taste hedonic value, aroma hedonic value, color hedonic value, viscosity hedonic value and general acceptance hedonic value. The findings revealed that the proportion of pineapples and carrots was a highly significant (P<0.01) effect on total dissolved solids, total microbes, levels of vitamin C, total acid, total sugar, pH, viscosity, color index, hedonic taste, aroma hedonic, color hedonic, general acceptance hedonic. The effect was significantly different (P>0.05) on the hedonic viscosity. Storage time had a highly significant (P<0.01) effect on total dissolved solids, total microbes, levels of vitamin C, total acids, total sugars, pH, viscosity, color index. Has no significant effect (P>0.05) on the hedonic of taste, hedonic of aroma, hedonic of color, hedonic of viscosity and hedonic of general acceptance. The interaction between the ratio of carrots to pineapple and storage time had a highly significant (P<0.01) effect on total dissolved solids, total microbes, vitamin C content, total acid, total sugar, pH, viscosity. had no significant effect (P>0.05) on color index, hedonic taste, aroma hedonic, color hedonic, viscosity hedonic, and generally accepted. The best treatment for A3S1, is the ratio of carrots to pineapple, was 20%:80% with a storage time of 7 days. The A3S1 treatment contained 57.9165 mg/100 g of vitamin C, 69.0870% total sugar, and 3.23 x 102 CFU/ml total plate count. The best treatment was then tested for antioxidant activity with a value of 95.37 μg/ml and testing for beta-carotene content with a value of 7.4866 μg/ml.
