Kappaphycus alverazii remains as a predominant source of kappa-carrageenan which is farmed extensively in Indonesia, Philippines and South East Asia. The current research focuses on the influence of concentration of salts and approach to dialysis on properties of carrageenan. Carrageenan due to its pronounced gelling and viscosifying properties, has gained significant usage in the areas of food, cosmetics, textiles, pharmaceutics, biomedicine, and numerous others. The process of extraction was conducted in a hot, alkaline condition at 80 oC for a duration of 2 hours. The alkaline substance used was KCl with 2% and 4% concentration and solvent to seaweed ratio was 20:1.Further, the resultant extracted samples were subjected to dialysis to evaluate the effect of dialysis on the quality of carrageenan. The absorbance peak at 849 cm–1 from Fourier Transform Infrared-Spectroscopy (FTIR) at all extraction conditions indicated D-galactose-4 sulphate related to kappa carrageenan obtained with no traces of \(\mu\)-precursor. The study demonstrated that the concentration of salts and the approach of dialysis have influenced the quality of yield, viscosity, gel strength, moisture content and ash content for the extracted carrageenan, which remains ideal for commercial applications.

Wound healing remains as a dynamic process and the type of dressing material significantly affects the efficacy of healing. The identification of ideal dressings to use for a particular wound type is an important requisite facilitating the entire process of healing. Chronic, high exudate wounds are dynamic in presentation and remain as a major health care burden. Researchers have sort to design and optimize biodegradable wound dressings that focuses to optimize moisture retentiveness, as superior character in the healing process. In addition, dressings have been designed to visualize the wound bed by improving the optical property, target and kill infection-causing bacteria, with the incorporation of antimicrobial agents, nanomaterials and numerous other measures. For the practitioners, choosing the optimal dressing decreases time to healing, provides cost-effective care and improves patient quality of life. The current mini review highlights the ideal characters of wound dressing materials and presents insights on the superior characters of carrageenan bio composites for prospective advancements in research in the area of wound care and management.
