Abstract

The purpose of this study was to analyze the effect of pectin and gelatin concentration on the physical, chemical and sensory properties of avocado (Persea americana Mill) sheet-jam. The research was conducted in Agricultural Chemistry Laboratory and Sensory Evaluation Laboratory, Department of Agricultural Technology, Faculty of Agriculture, Sriwijaya University, from March 2017 to June 2017. This research was conducted by using Factorial Completely Randomized Design (RALF) with two treatment factors and each repeated three times. The first factor was gel-forming (pectin and gelatin) and second factor was the concentration of gelling material (0.3% ; 0.6% ; 0.9%). The parameters observed were texture, color, moisture content, ash content, total acid content, and organoleptic test using hedonic test consisting of color, aroma, taste and texture. The results showed that gel-forming factors such as pectin and gelatin had significant effect on texture and ash content. Factor of gel-forming concentration that is pectin and gelatin had significant effect on texture, color (L, C), water content and total acid content. The interaction of gel-forming treatment and the gel-concentration treatment had significant effect on water content. Based on the hedonic test, the best treatment was A1B3 (pectin 0.9%) hardness characteristic 189.60 gf, L* 53.53%, C* 49.97%, ho 77.93o, moisture content 27.44%, ash content 0.27%, total acidity content of 0.74%, and hedonic score on texture (3.44), taste (3.04), color (3.2), and flavor (2.56).
