Preparation of semi-refined kappa-carrageenan: Recycling of alkali solution and recovery of alkali from spent liquor
(T)he data oil the preparation of semi-refined carrageenan (SRC) from Hypnea musciformis and Eucheuma cottonii from the Indian sea coast are presented in the article. Improvements in the process of preparation of SRC such as: reduction in usage of water, reduction in soaking time of seaweed, increase in throughput, reuse of alkali, minimization of waste and regeneration of good quality KOH from spent liquor are achieved. Results obtained on lab scale (50 g seaweed) and bench scales (2.5 and 15 kg seaweed) are presented in the article and requirements of alkali, water and steam for a commercial unit are projected.
