The objective of this paper is to analyuse carrageenan content and gel strength of refined
carrageenan produced from Eucheuma cottonii. The cottonii seaweed samples were harvested at different
age (40, 45 and 50 days) and carrageenan extraction was done through a series of process. First, the seaweed
was soaked in tap water for 12 hours then followed subsequently by cooking in an autoclave at 121°C for
15 minutes and at 100°C for 60 minutes. Following the cooking process, the samples were crushed in hot water
and then filtered using cheesecloth. The filtrate obtained was added into propanol to precipitate the
carrageenan in the filtrate and carrageenan fiber obtained was sun dried for four days to obtain dry carrageenan.
Results from this experiment indicated that carrageenan yield was only slightly affacted by the age of harvest.
Average yield at 40 and 45 days of age was 42.29±1.73 % and 42. 18±0.65 % respectively and average yield at
50 days of age was 44.66±3.20 %. The gel strength of the carrageenan was also affected by the age of seaweed.
The gel strength was found to increase significantly at the age of 50 days with average gel strength of about
84.93%. This value is significantly higher than those obtained at 40 and 45 days of age.
