The paper presents an international consensus for a standardised static<italic>in vitro</italic>digestion method food.
Developing a mechanistic understanding of the impact food structure and composition on human health has increasingly involved simulating digestion in upper gastrointestinal tract. These simulations have used wide range different conditions that often very little physiological relevance, this impedes meaningful comparison results. The standardized protocol presented here is based an international consensus developed by COST INFOGEST network. method designed to be with standard laboratory...
Standardised recommendations for a physiologically relevant, semi-dynamic <italic>in vitro</italic> simulation of upper GI tract digestion.
Within the active field of in vitro digestion food research, COST Action INFOGEST aimed to harmonize protocols simulating human on basis physiologically inferred conditions. A harmonized static (IVD) method was recently published as a primary output from this network. To validate protocol, inter-laboratory trials were conducted within first study performed using skim milk powder (SMP) model and served compare different in-house used among members. In second applying degree consistency...
Understanding the mechanisms of food digestion is paramount importance to determine effect foods have on human health. Significant knowledge fate during has been generated in healthy adults due development physiologically-relevant vitro models. However, it appears that performance oro-gastrointestinal tract affected by ageing and a model simulating digestive conditions found younger adult (<65 years) not relevant for an older (>65 years). The objectives present paper were: (1) conduct...
The aggregation process of β-lactoglobulin (β-lg) from 0 min to 20 h was studied using atomic force microscopy (AFM), scanning transmission electron (STEM), sodium dodecyl sulfate−polyacrylamide gel electrophoresis (SDS−PAGE), and in situ attenuated total reflectance−Fourier transform infrared spectroscopy (ATR−FTIR). Fibril assembly monitored real time AFM up h. From 85 min, β-lg monomers deformed expanded with some aggregation. After fibrillar structures were formed, exceeding 10 μm...
The effects of heat-induced denaturation and subsequent aggregation whey protein isolate (WPI) solutions on the rate enzymatic hydrolysis was investigated. Both heated (60 °C, 15 min; 65 5 70 min, 75 80 10 min) unheated WPI (100 g L–1 protein) were incubated with a commercial proteolytic enzyme preparation, Corolase PP, until they reached target degree (DH) 5%. heating characterized by large aggregate formation, higher viscosity, surface hydrophobicity hydrolyzed more rapidly (P < 0.001)...
The ferrous (Fe2+) chelating capabilities of WPI hydrolysate fractions produced via cascade membrane filtration were investigated, specifically 1 kDa permeate (P) and 30 retentate (R) fractions. kDa-P possessed a Fe2+ capability at g L(-1) equivalent to 84.4 μM EDTA (for kDa-R the value was 8.7 EDTA). Fourier transformed infrared (FTIR) spectroscopy utilized investigate structural characteristics hydrolysates molecular interactions with Fe2+. Solid-phase extraction employed enrich for...
