Carrageenan is a polysaccharide extracted from the red seaweed Hypnea musciformis, and it has been widely studied due to its abundance on the coast of several countries, including Brazil. It is used in the production of aqueous, meat and dairy products, such as dessert gels, gels products made from fish, fruit juices and powder concentrates, animal feed (canned), spices and sauces, puddings, ice cream, chocolate, among others. Due to the wide applicability of carrageenan and the fact that industries are becoming increasingly dependent on it, there is debate nowadays on the large-scale production of carrageenan, both through cultivation and with methods for obtaining higher yield of this polysaccharide. In this sense, this study aimed to make a comparison between four different methods of carrageenan extraction, seeking to prove the best route to achieve the highest level of performance. In the methods discussed, seaweeds were bleached or remained unbleached, and were subsequently sun-dried or oven-dried, in the following treatments: (T1), sun-dried and bleached; (T2) sun-dried and unbleached; (T3) oven-dried and bleached, and (T4) oven-dried and unbleached. There was a difference in the yield of carrageenan obtained by these pre-extraction treatments; T2 was the most satisfactory, with a yield of 21.63%.
