Abstract


aragenan is an hyrocolloid essence which is long chain polysaccharide essence that mixed from Eucheuma sp, Chondrus sp., dan Gigartina sp. Caragenan has important rule as stabilizer, thickener, gelling agent, and emulsion (Anggadiredja, dkk., 2006).
The purpose of this study were to know the interaction between type and concentration. Caragenan toward the quality of apple syrup, to know the influence of type caragenan toward the quality of apple sirup and to know the influence of type caragenan toward the quality of apple syrup and to know the influence of concentration of Caragenan toward the quality of apple syrup.  This research was done in Technology of Agriculture Product Laboratory, Universitas of Muhammadiyah Malang on July-October 2008. This study used factorial random group technique with two factors dan three repetitions. Factorial one is (Kappa and iota) and factorial two is concentrate (0%, 0,25%, 0,50%, 0,75% dan 1%). The Parameter of this study included viskosity, vitamin C, total acid, overcast sugar, pH, dan organoleptic (taste,smell, color, and performance).
Based on the result of the research, type and concentration of caragenan showed that there was an interaction toward viscosity of apple syrup. The treatment type of caragenan showed that the real influence toward total acid of apple syrup, whereas, the treatment concentration of caragenan showed that the real influence toward total acid of apple syrup, vitamin C, overcast sugar, pH, smell score, taste score, and performance score. Based on De Garmo test showed that the treatment of iota-karagenan 1% was the best score with total acid 0,48%; viskosity 478,90cps; vitamin C 0,17%; overcast sugar 27,57% pH 4,02, score smell 3,07, color score 3,27, taste score 3,33, dan performance score 2,60, and followed by treatment combination of kappa-caragenan 0,75%; as the second place and kappa-caragenan 1% as the third place.
