Abstract

This study aimed to extract carrageenan from the red seaweed Eucheuma cottonii using potassium hydroxide (KOH) as solvent with the sonication method. Extraction was performed at 80°C for 60 minutes with a seaweed-to-solvent ratio of 1:30 (w/v) at an ultrasonic frequency of 40 kHz. The optimized extraction conditions yielded a carrageenan yield of 21.08%. Quality parameters evaluated included moisture content, ash content, viscosity, and gel strength. Moisture content (0.07%), ash content (0.37%), and viscosity (34.2 cP) all met FCC and FAO standards. However, the gel strength of 14.361 g/cm² did not meet the commercial standard.
