Physico-chemodiversity variation between the most common calcareous red seaweed, Eastern Harbor, Alexandria, Egypt
The present study sought to detect the difference in physicochemical properties and the proximate compositions of common calcareous red seaweeds ''Corallina officinalis, Jania rubens, and Amphiroa rigida''. J. rubens was recorded highly water (WHC), and oil holding capacity (OHC)...

| description | The present study sought to detect the difference in physicochemical properties and the proximate compositions of common calcareous red seaweeds ''Corallina officinalis, Jania rubens, and Amphiroa rigida''. J. rubens was recorded highly water (WHC), and oil holding capacity (OHC) (1.619 ± 0.08 g g−1 DW, 3.1 ± 0.50 g g−1 DW, respectively) than those other species relating to the hydrophilic nature of polysaccharides, whereas swelling water capacity (SWC) was higher in A. rigida (5.25 ± 0.38 mL g−1 DW). A higher value of carbohydrates (49.88 ± 2.56% DW) was observed in J. rubens, Contrariwise, protein (36.99 ± 1.36% DW) and lipid contents (5.85 ± 0.49% DW) were higher in C. officinalis. Albumin and protamine protein fractions were higher in J. rubens specimens (45.11 ± 2.29 mg g−1 & 0.0014 ± 0.0007 mg g−1 DW, respectively) than other species. While globulin and glutilin (31.70 ± 1.90 mg g−1 DW & 41.93 ± 2.20 mg g−1 DW, respectively) were high in A. rigida. Contrariwise, insoluble protein fraction was high in C. officinalis (9.50 ± 0.50 mg g−1 DW). J. rubens specimens were recorded maximum values of the photosynthetic pigments. The different surface types and elemental analysis of three species were examined by Scanning electron microscopy (SEM) and Energy dispersive X-ray spectroscopy (EDX). From fourier transform infrared (FTIR) spectroscopy the S–S stretching peak of disulfides group at 462 cm−1 was the fingerprint of J. rubens. From GC-MS data A.rigida possesses 16 bioactive components with biological properties. As a result, J. rubens and A. rigida could be employed as an ingredient in functional foods and drug manufacture. |
