Extensive purification of plant proteins is probably not a prerequisite for their emulsifying properties, however, details the interfacial stabilization mechanism less purified protein extracts are sufficiently known. Phenolic compounds present in can interact with proteins, inducing aggregation, impeding properties. Here, we show that when rapeseed mixture (RPM) containing 40 wt% and 6 sinapic...

Ferulic acid (FA), a ubiquitous natural phenolic phytochemical present in seeds, leaves, bothin its free form and covalently conjugated to the plant cell wall polysaccharides, glycoproteins,polyamines, lignin and hydroxy fatty acids. FA plays a vital role in providing the rigidity to the cell wall and formation of other important organic compounds like coniferyl alcohol, vanillin, sinapic, dife...

Biosynthesis, Puberulin, C oum arins, Agathosma puberula Umbelliferone and scopoletin are well utilized as precursors o f puberulin , a 7-O-prenyl e ther o f isofraxidin elaborated by Agathosma puberula Fourc. (R utaceae). As ferulic, sinapic, and caffeic acids were all m ore poorly utilized than 4 '-hydroxycinnam ic (/?-coumaric) acid, the partial biosynthetic route: 4 '-hydroxycinnam ic acid ...

Réblová Z. (2012): Effect of temperature on the antioxidant activity of phenolic acids. Czech J. Food Sci., 30: 171–177. The effect of temperature on the antioxidant activity of phenolic acids (gallic, gentisic, protocatechuic, syringic, vanillic, ferulic, caffeic, and sinapic; 0.5 mmol/kg) was studied in pork lard, using an Oxipres apparatus, at a temperature range of 90°C to 150°C. The antiox...

Antioxidant norbornene-based monomers bearing biobased sterically hindered phenols (SHP)-NDF (norbornene dihydroferulate) and NDS (norbornene dihydrosinapate)-have been successfully prepared through biocatalysis from naturally occurring ferulic and sinapic acids, respectively, in presence of Candida antarctica Lipase B (Cal-B). The ring opening metathesis polymerization (ROMP) of these monomers...

This paper focuses on developing a sustainable and integrated process for the biocatalytic extraction of sinapic acid from waste biomass oleaginous “oil-bearing” seeds. Using an optimized chemo-enzymatic technique, sinapine was effectively liberated mustard bran then completely hydrolyzed into acid. Several parameters were to release (e.g., species, methods, production dates, ethanol concentrat...
