Abstract

The problems faced by carragenan producers is the optimation of the presipitation ingridients.  Presipitation process on the extraction carragenan from seaweeds is very essential since the fraction with higher molecul weight will be separated from the lighter one, and it can influence the gel strength which is one of the important characteristics.  Precipitation ingridients used in this experiments consist of  methanol, ethanol, and isopropanol. The extraction of carragenan from Eucheuma cottonii in this research follows some steps e.g. extraction with KOH 6%, heating, rinsing, pulping, hot filtering, addition of KCL 5%, precipitation, washing-rinsing, squizing, drying and grinding. Quality parameters observed were gel strength, moisture content, ash content, viscosity, boiling point, and gel point. From these experiments methanol ingridients exhibited the best characteristics of refined carragenan in term of gel strength (1407,83 g/cm2), moisture content (9,96%), ash content (18,7%), viscosity (251 cP), boiling point (27,6°C), and gel point (30,3°C).  In general refined carrageenan processed with these presipitation meet the standard from FAO (Food Agriculture Organization), FCC (Food Chemicals Codex), dan EEC (European Economic Community).

Abstract

East Kalimantan province has developed seaweed aquaculture in particular, especially in the area of Bontang, East Kutai, Berau and Nunakan. The seaweed potential is quite large at around 170,000 tonnes / year (Department of Fisheries 2012). Like land plants in general, seaweed also has chlorophyll or other pigment colors. In addition, seaweed contains vitamin A and vitamin E (Sunarto, 2003). Vitamin E prevents lipofuscin, oxidized fats trigger premature aging of the skin. The purpose of this study was to determine the types of seaweed extraction method to obtain Euchema cotonii seaweed extract with vitamin E in the form of Tocopherol. Furthermore seaweed extract is added as an additive into the soap as much as 2%. Extraction technique used is the method of cold crystallization with methanol. Seaweed extract were tested using HPLC method and obtained tocopherol content 0.17 to 1.14 IU, free fatty acids 3.54%-4.42%, peroxide 4.05%-4.15%. The addition of seaweed extract as a source of tocopherols did not affect the quality of the soap produced according to standard SNI 06-3532-1994 (SNI soap)
