Marine algae have gained substantial attention from various scientific and commercial fields. The reason behind its importance is due to the rich source of bioactive compounds like proteins, carbohydrates, lipids, other pigments. algae-derived carrageenans polysaccharides are used in food, medicine, cosmetic items, gelling, emulsifying, stabilizing agents. carrageenan has also photoprotective a...

Objectives. To study the effects of various concentrations food additive E407a (semi-refined carrageenan) on metabolic activity fetal liver cells, splenocytes, and bone marrow cells. Material methods. Fetal liver, splenocytes cell cultures were incubated with at varying from 0 mg/ml to 10 for 24 hours (n=8). analyze this a colorimetric MTT assay was used. It is based ability viable, metabolical...

Seaweed is an important global commodity since it the source of many products such as carrageenans, agar, alginates, and bioactive compounds. processing energy intensive process involves heating large volumes seaweeds in alkali solutions at high temperatures for up to six hours. To increase efficiency, ohmic based system has been developed but not tested thoroughly. Therefore, objective this st...

Abstract This study focusses on the valorization of red seaweed Mastocarpus stellatus, collected in Northern coast Portugal, as a natural source high value compounds due to its beneficial properties. An annual monitoring was performed by determining lipids, ash, carbohydrates, phycobiliproteins, total phenolic compounds, antioxidant capacity and carrageenan from three different rocky shores loc...

In this study, we monitored changes in cell wall sulfated galactans the red seaweed Grateloupia imbricata after rapid (48 h) induction of cystocarp maturation and carpospore development by volatile hormone methyl jasmonate (MEJA). Synthesis galactans, carrageenans, which requires UDP galactose, was followed expression analysis genes encoding phosphoglucomutase (PGM), galactose-1-phosphate uridy...

Native starch from potatoes and hybrid carrageenans the red alga Mastocarpus stellatus have been used as gluten-free gelling matrices to obtain functional hydrogels. The enrichment of with antioxidant compounds natural sources is an increasing market trend. In this context, work aimed at formulation thermo-rheological characterization hydrogels using potato agro-industrial waste kappa–iota extr...
