Abstract

The Effect of Glucose and FructoseConcentrations on the Physical, Chemical and Sensory Characteristics of Senduduk Fruit Syrup (Melastoma malabathricum L.) (Supervised by FILLIPRATAMA). This study aims to determine the effect of glucose and fructoseconcentrations on the physical, chemical and sensory characteristics of sendudukfruit syrup Melastoma malabathricum L.). This research was conductedinJanuary 2023 until completion at the Laboratory of Chemistry, ProcessingandSensory of Agricultural Products, Department of Agricultural Technology, Faculty of Agriculture, Sriwijaya University. This study used a Non Factorial Completely Randomised Design with six treatments and each treatment wasrepeated three times. The treatment was the ratio of glucose and fructose(50%:10%) ; (45%:15%) ; (40%:20%) ; (35%:25%) ; (30%:30%) and (25%:35%). The parameters observed included physical characteristics (viscosity and colour), chemical characteristics (pH level, antioxidant activity and sugar content), andsensory characteristics (aroma, colour and taste). The results showed that the ratioof glucose and fructose had a significant effect on sensory characteristics (taste) and physical characteristics (viscosity). Senduduk fruit syrup with a ratio of 25%glucose and 35% fructose was the best treatment based on sensory characteristics(hedonic test) with a score of 3.44, chemical characteristics for pH3.39, sugar content 51.13%, and antioxidant activity 69.76 ppm, as well as physical characteristics for viscosity 307 cP and colour (lightness (L*) 31.117, blueness(b*) -0.99 and redness (a*) 5.98)
