A new edible coating of fish gelatin incorporated into açaí oil to increase the post-harvest shelf life of tomatoes.

Açaí oil (Euterpe oleracea) is a new active ingredient, originating from the Amazon Forest, which offers numerous benefits as an antioxidant and antimicrobial agent. Here, we report how açaí oil can be used as an active ingredient in gelatin coatings to increase the shelf life of tomatoes. The optimized viscosity and gel strength conditions were 5.

Sulfated polysaccharides act as baits to interfere with the binding of the spike protein (SARS-CoV-2) to the ACE2 receptor and can be administered through food.

Human civilization is experiencing a global crisis involving an unprecedented viral pandemic, with a high mortality rate, uncontrolled spread, and few effective drugs for treatment. Here, we critically evaluate how sulfated polysaccharides can be applied via foods to reduce the infectious process and increase the chances of an adequate immune response. The approach is directed to the infectious process by SARS-CoV-2 and protein S as a therapeutic focus.

Polysaccharides obtained from natural edible sources and their role in modulating the immune system: Biologically active potential that can be exploited against COVID-19.

Background: The global crisis caused by the outbreak of severe acute respiratory syndrome caused by the SARS-CoV-2 virus, better known as COVID-19, brought the need to improve the population's immunity. The foods rich in polysaccharides with immunomodulation properties are among the most highly rated to be used as immune response modulators. Thus, the use of polysaccharides obtained from food offers an innovative strategy to prevent serious side effects of viral infections.

Occurrence and possible roles of polysaccharides in fungi and their influence on the development of new technologies.

The article summarizes the roles of polysaccharides in the biology of fungi and their relationship in the development of new technologies. The comparative approach between the evolution of fungi and the chemistry of glycobiology elucidated relevant aspects about the role of polysaccharides in fungi. Also, based on the knowledge of fungal glycobiology, it was possible to address the development of new technologies, such as the production of new anti-tumor drugs, vaccines, biomaterials, and applications in the field of robotics.

Obtaining extracts rich in antioxidant polysaccharides from the edible mushroom Pleurotus ostreatus using binary system with hot water and supercritical CO.

Pleurotus ostreatus is an edible mushroom with pharmacological potential, due to its metabolites, mainly polysaccharides. On here, the development of a new methodology for the recovery of extract rich in antioxidant polysaccharide was reported. The extracts were characterized, evaluated for antioxidant activity in vitro and in cell models and cytotoxicity.

Polysaccharides of mushroom Pleurotus spp.: New extraction techniques, biological activities and development of new technologies.

The biodiversity of mushrooms Pleurotus spp. is impressive due to its complexity and diversity related to the composition of chemical structures such as polysaccharides, glycoproteins and secondary metabolites such as alkaloids, flavonoids and betalains. Recent studies of polysaccharides and their structural elucidation have helped to direct research and development of technologies related to pharmacological action, production of bioactive foods and application of new, more sophisticated extraction tools.

Improvement of the characteristics of fish gelatin - gum arabic through the formation of the polyelectrolyte complex.

The aim of this study was to evaluate and characterize the interaction between fish gelatin (FG) and Gum Arabic(GA) and its effects in obtaining optimal atomization conditions. The optimal conditions (D = 0.866) founded in this paper were: Gum Arabic concentration of 33.
