An in vitro experiment was carried out to assess how nonstarch polysaccharide (NSP)-degrading enzymes influence the fermentation of dietary fiber in the pig large intestine. Seven wheat and barley products and cultivars with differing carbohydrate fractions were hydrolyzed using pepsin and pancreatin in the presence or not of NSP-degrading enzymes (xylanase and β-glucanase) and the filter reten...

The reported effects of grapefruit (Citrus paradisi Macf.) juice on oral bioavailability of certain prescription drugs have led to the discovery of the inhibition by compounds in grapefruit of cytochrome P450 3A4 (CYP3A4) in the intestinal wall and liver. Recent evidence indicates that furanocoumarins related to bergamottin [5-[(3',7'-dimethyl-2',6'-octadienyl)oxy]psoralen] are primarily respon...

Yacon is a perennial plant originating from the Andean region whose roots have been receiving increased attention due to their high content of prebiotic fructooligosaccharides (FOS). Apart from many health benefits, FOS have interesting characteristics as food ingredients, so are used as sugar substitute, and their extraction from yacon roots may be an alternative to commercially available FOS....

The aim of this work is to illustrate the structural and parametric optimization of continuous hybrid distillation-pervaporation process with different configurations such as series, parallel, and series-parallel arrangement of pervaporation modules in the pervaporation network, and to propose a generalized methodology for difficult separations. A superstructure representation of hybrid process...

The aim of this work was to apply unconventional extraction methods including ultrasonication (US), high voltage electrical discharge (HVED) and pulsed electric field (PEF) to extract polyphenols from grape seeds and concentrate the extracts by ultrafiltration. A comparative evaluation of the three extraction methods for release of polyphenols from grape seeds was investigated. The results show...

A quantitative analysis of the effects of variable ®ber properties on the performance of a cross̄ow hollow ®ber gas separation module is presented. The effects of variations in size, permeance, and selectivity are considered. Fiber variability is detrimental to performance. The recovery and ̄ow rate of an enriched retentate stream decrease as variability increases. Some ®bers may actually stop p...

The food industry is focused on developing plant-based foods that incorporate pea protein isolates. However, these ingredients are often described as having persistent beany, bitter, and astringent notes, which can decrease the desirability of resulting foods. These perceptions rooted in complex composition volatile non-volatile compounds aim our study was to better understand how fractions iso...

Nowadays, AgNPs are extensively used in the manufacture of consumer products,(1) water disinfectants,(2) therapeutics,(1, 3) and biomedical devices(4) due to their powerful antimicrobial properties.(3-6) These nanoparticle applications are strongly influenced by the AgNP size and aggregation state. Many challenges exist in the controlled fabrication(7) and size-based isolation(4,8) of unfunctio...
