Potensi Pemanfaatan Ekstrak Etanol Alga Merah (Kappaphycus alvarezii) sebagai Pengawet Alami Pengganti Formalin pada Daging Ikan
[Potential Use Of Red Algae Ethanol Extract (Kappaphycus alvarezii) As Formalin Substitute Natural Preservative In Meat Fish]

open access: yesJurnal Ilmiah Perikanan dan Kelautan, 2013
Fish meat is more nutritious source of protein and relatively safe for human consumption. Fish meat more easily damaged than red meat product quality, so it is necessary that the process of pickling fish maintained in fresh condition and suitable for ...

The freshwater red algae ( Batrachospermales , Rhodophyta ) of Africa and Madagascar I. New species of Kumanoa , Sirodotia and the new genus Ahidranoa ( Batrachospermaceae )

open access: yesPlant and Fungal Systematics, 2020
Our knowledge of the diversity of African freshwater red algae is rather limited. Only a few reports exist. During our field work in the last five years we frequently encountered freshwater red algae in streams in Rwanda and Madagascar.

Studies on Polyethers Produced by Red Algae [PDF]

open access: yesMarine Drugs, 2010
Two novel squalene-derived triterpenes, spirodehydrovenustatriol (3) and 14-keto-dehydrothyrsiferol (4) were isolated from the red alga Laurencia viridis, together with two new and unusual C17 terpenoids, adejen A (5) and B (6). These truncated structures possess structural similarities with other known squalene metabolites and their biogenetic origin ...

Responsive Membrane Antenna Enables Adaptive Biohybrid Interface for Photosynthesis Promotion, Stress Reporting and Modulation

open access: yesAdvanced Science, EarlyView.
An environmentally responsive antenna assembled onto the algal cell membrane creates a biohybrid with a responsive interface that promotes photosynthesis under normal conditions and shifts to H2O2‐triggered stress reporting and modulation upon stress onset, boosting environmental sensing and adaptive response.

Health Benefits of Polysaccharides in Red Algae: A Comprehensive Review

open access: yesFood Frontiers
Humans have long consumed red algae (especially by the Asian community), and their polysaccharide extracts (carrageenan, agar) are extensively used in the food industry as gel thickeners. Furthermore, due to the wide variety of habitats red algae inhabit,

Stabilization of PUFA‐Rich Mayonnaise Against Lipid Oxidation: A Review of the Last Three Decades of Research

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Mayonnaise, a widely consumed oil‐in‐water emulsion, is highly susceptible to lipid oxidation due to its high content of polyunsaturated fatty acids (PUFAs) and the presence of pro‐oxidant factors such as low pH and iron from egg yolk. Over the past three decades, extensive research has focused on understanding oxidation mechanisms, analytical
