Recent studies on the digestion of proteins by the proteolytic enzymes of the gastrointestinal tract have resulted in a considerable revision of our concepts on how these enzymes act. Tiselius and Eriksson-Quensel (1) studied the mechanism of the peptic digestion of crystalline egg albumin by electrophoretic examination of the products of proteolysis. They observed that, as digestion proceeded,...

The rate of protein digestion imposes significant limitations on high-throughput protein identification using mass spectrometry. In this report, we demonstrate that proteins are readily digested by trypsin in the presence of organic solvents such as methanol, acetone, 2-propanol, and acetonitrile. The rates of protein digestion in organic solvents, as indicated by the abundances of digest fragm...

Phytic acid is a storage form of phosphorus which is found in plant seeds and in many roots and tubers (1). Phytic acid has long been recognized as an antinutrient for its ability to bind to, precipitate and decrease the availability of diand trivalent cationic minerals (2). The reduced availability of minerals will prove disadvantageous, as minerals play a major role in many enzyme systems and...

Acrylamide (AA)-induced toxicity has been associated with accumulation of excessive reactive oxygen species. The present study was therefore undertaken to investigate the protective effect of blackberry digests produced after (BBD) in vitro gastrointestinal (GI) digestion against AA-induced oxidative damage. The results indicated that the BBD (0.5 mg/mL) pretreatment significantly suppressed AA...

Abstract Purpose To explore the methane production potential and microbial community changes of combined anaerobic digestion chicken manure corn straw. Increase production, reduce environmental pollution caused by burning livestock straw, provide some theoretical references for construction operation actual biogas projects. Methods Different proportions (3%, 5%, 10%) straw were added to systems...

In this study, an apricot kernel milk suspension was prepared, for which Hac?halilo?lu-type raw and roasted kernels were used. Protein, total lipid, ash contents of determined. Palmitic acid, oleic linoleic acid considered as major fatty acids according to gas chromatography. During in vitro gastrointestinal digestion, the proteins hydrolyzed pepsin-resistant No difference recorded between panc...

In the context of increasing pressure regarding sustainable utilization food waste in a circular economy, one trends is their biological transformation, through anaerobic digestion, into biogas as renewable source energy. We presented physical-chemical properties main categories from different sources: dairy, meat, and poultry, fish, fruit vegetable, cereal bakery, brewing winery industries, ot...

OBJECTIVES The purpose of this study was to assess the risk of ingestion exposure of lead by particle sizes of crumb rubber in artificial turf filling material with consideration of bioavailability. METHODS This study estimated the ingestion exposure by particle sizes (more than 250 um or less than 250 um) focusing on recyclable ethylene propylene diene monomer crumb rubber being used as arti...

Recovery of gentamicin from renal cortical tissue (assayed by fluorescence polarization immunoassay) was highest (P less than 0.05) when using a sodium hydroxide (NaOH) digestion procedure without homogenization (90.0 +/- 5.4%), followed by homogenization with NaOH digestion (85.8 +/- 7.7%) and homogenization with trichloroacetic acid precipitation (84.4 +/- 3.3%). Simple homogenization recover...

The aim of research was to determine polyphenols bioaccessibility and antioxidant properties thermally-treated skimmed goat milk enriched with sunflower bee-collected pollen through in vitro digestion. HPLC analysis confirmed that pollen-enriched contained flavonols as the main phenolic fraction (80.7–76.2%) followed by acids (14.2–17.4%). Among individual compounds quercetin-3-O-glucoside (155...
