Influence of potassium hydroxide concentration on the carrageenan functional group composition
Potassium Hydroxide treatment of seaweed is one of the common processes in the production of semi-refined carrageenan (SRC) across South-east region. However, potassium hydroxide will influence the properties of the product through the effect on the variation of functional group composition in the c...
