WHC was analyzed by modified Centrifugation method. 200 mg of seaweed sample was placed in 20 ml of distilled water in a centrifugation tube and were kept in a shaker for 24 h. To determine the effect of temperature on WHC, the samples were kept at 25◦C and 37 ◦ C. WHC was expressed as weight of gram of water held by 1 g of dry weight of sample.
