Recent advances in digestion methods used in the analysis of precious metal samples by spectrometric techniques are reviewed. The applicability of a fire assay, a wet acid treatment, chlorination and alkaline oxidizing fusion to a quantitative recovery of metals from various materials is discussed. Data on the precious metal contents obtained by using particular digestion methods as well as UV-...

It has been estimated and demonstrated that the antioxidant capacity of proteins is increased as a result digestion in gastrointestinal tract, which can be contributed by denaturation digestion. This study aimed to evaluate effect proteolytic on activity bovine serum albumin (BSA) chicken egg white model systems. Denaturation with an anionic detergent (sodium dodecyl sulfate) papain trypsin act...

we sought to determine levels of oral bioaccessibility of hydroxymethylfurfural (hmf) from frequently consumed dried fruits in iran. fifty samples from frequently consumed types of dried fruits were analyzed for moisture, acidity and hmf content before and after in vitro digestion. besides, bioaccessibility of hmf in dried fruits using an in vitro gastrointestinal digestive model and hmf intake...

Abstract The stability of tea phenolic compounds is influenced by pH value and digestive processes. However, the complex mixture constituents in may modulate these during digestion. In this study, infusions obtained from green, black, Oolong leaves were exposed to vitro simulated gastrointestinal digestion, ( +)-catechin, caffeine, (?)-epicatechin, epigallocatechin-3-gallate (EGCG), gallic acid...
