Production of iron-chelating proteinous hydrolysate from freshwater prawn, Macrobrachium nipponense
In this study, freshly harvested prawn, Macrobrachium nipponense were hydrolyzed with pepsin to develop a food ingredient and iron supplement. The degree of hydrolysis, protein/peptide concentration and iron-chelating capacity were verified by TCA soluble assay, direct UV spectrophotometric method and orthophenanthroline-based colorimetric assay, respectively. The result of TCA soluble assay re...

متن کاملVitellogenesis during the ovarian development in freshwater female prawn Macrobrachium rosenbergii (De Man)
In the present investigation, vitellogenesis during ovarian development in the freshwater prawn Macrobrachium rosenbergii was assessed. Ovarian development was classified into five stages based on size, colour and texture of ovary. Interestingly, histological results clearly indicate that the oocyte development gradually increased from stages I to V based on the yolk material accumulation. Besi...
