KARAKTERISTIK SELAI LEMBAR SIRSAK (Annona muricata Linn) DENGAN PENAMBAHAN PEKTIN DAN GELATIN = CHARACTERISTICS OF SOURSUP (Annona muricata Linn) SHEET JAM BY PECTIN AND GELATIN ADDITION
Daftar Isi:
- The objective of this research was to determine the effect of pectin and gelatin on the characteristics of soursop (Annona muricata Linn) sheet-jam. The research was conducted at Agricultural Product Chemical Laboratory, Agricultural Technology Department, Faculty of Agriculture, Sriwijaya University, from September 2017 to April 2018. The experiment used a Factorial Completely Randomized Design with two factors and each treatment was repeated three times. The first factor was gelling agents (pectin and gelatin) and the second factor was the concentration of gelling agents (0.1%, 0.3%, 0.5% w/w). The parameters were physical characteristic (texture), chemical characteristics (moisture contents, total of dissolved solids, pH, vitamin C, and antioxidant activity). The results showed that the gelling agents, concentration of gelling agents, and the interaction of gelling agent and its concentration had significant effect on texture, moisture contents, and pH. The concentration of gelling agents had significant effect on total dissolved solid and vitamin C. There was no significant effect of treatment on antioxidant activity.
