Varying the β-carotene (0.1-0.3 g kg(-1)) and whey protein isolate (WPI) (2-20 g kg(-1)) concentrations in an oil-in-water (O/W) emulsion influenced the partitioning and stability of β-carotene upon 30 d storage at 25 and 40 °C. The total β-carotene in the emulsion was extracted with a solvent and quantified using UV/visible spectroscopy. The β-carotene in oil phase was obtained using in situ Raman micro-spectroscopy. The β-carotene in the aqueous phase was obtained by difference. Increasing β-carotene concentration resulted in increased partitioning of β-carotene into the aqueous phase whereas increasing WPI concentration had the opposite effect...

Zearalenone (ZEN), one of the most common mycotoxins found in human food and animal feed, has been shown to be effectively detoxified by vitamin C (Vc). The aim of this study was to investigate how vitamin C protects the piglet liver against oxidative stress induced by ZEN. A total of thirty-two healthy female crossbred weaning piglets (Duroc × Landrace × Large white) with an initial weight of 12.27 ± 0.30 kg were randomly divided into four treatment groups of eight piglets per group. The dietary treatments included two zearalenone levels (0 mg kg(-1) and 1...

Radix Tetrastigma (RT), a herbal medicine and functional food in China, showed strong antiproliferative activities in vitro. However, the effects and the underlying mechanism of phenolic-rich extract of RT in H22 tumor-bearing mice are still unknown. Thus, the phenolic profiles and antitumor/antioxidant activities of a solid phase extraction (SPE) semi-purified extract of RT were investigated by a combination of chemical assays, LC-QTOF-MS/LC-QqQ-MS techniques and a tumor-bearing mice model. As a result, the total phenolic/flavonoid contents (TPC/TFC) and 24 individual phenolics were identified and quantified, which showed higher contents than that of crude extract...

The impacts of onion peel (OP) and Dendropanax morbifera (DM), as excipient foods rich in flavonols, on the digestive recovery, intestinal absorption, and pharmacokinetics of GT epicatechins were studied via an in vitro digestion model system with Caco-2 cells and an in vivo study. The digestive stability of total epicatechins recovered from GT upon the addition of 2% DM was up to 1.12 times higher than that observed with OP. The combined effects of OP and DM, which were observed with 2% OP + DM in a ratio of 1 : 4 (w : w), significantly increased (by a factor of 1...

Consumers and the food industry are demanding healthier products. Expanded snacks with a high nutritional value were developed from different rice, pea and carob flour blends. The proximate composition, starch (total and resistant), amylose and amylopectin, dietary fiber (soluble and insoluble) contents, and the in vitro protein digestibility of different rice-legume formulations, were evaluated before and after the extrusion process. Compared with the corresponding non-extruded blends (control), the extrusion treatment did not change the total protein content, however, it reduced the soluble protein (61-86%), the fat (69-92%) and the resistant starch contents (100%)...

Cohesiveness and flowability of particulated food systems is of particular interest in the oral processing and swallowing of food products, especially for people suffering from dysphagia. Although cohesiveness of a bolus is an essential parameter in swallowing, a robust technique for objective measurement of cohesiveness of particulated semi- or soft-solids is still lacking. In our approach the ring shear tester is used to measure the cohesiveness and flowability of a model particulated food system based on fresh green pea powders and pastes with controlled moisture content...

Functional confectionery can be exploited as a vehicle for the protection of phenolic compounds (PCs) and for enhancing absorption during the gastrointestinal (GI) process. In this study, a confection containing 20% of mango bagasse (MB), gelatin and pectin was formulated. The PC profile, antioxidant capacity, in vitro bioaccessibility and apparent permeability (Papp) during mouth-stomach-intestine digestion (15, 30, 60, 120 min) and in vitro colonic fermentation (6, 12, 24 h) were evaluated for MB and the mango bagasse confection (MBC)...

The aim of this research was to investigate the antioxidant and anti-apoptotic activities of Potentilla anserina polysaccharide (PAP) on kidney damage induced by cadmium (Cd) in vitro and in vivo. PAP has been suggested to have anti-oxidation, anti-apoptosis, immunoregulation, antimicrobial, antitussive, and expectorant abilities. In this study, PAP was extracted and the major components of PAP were analyzed. It was shown that PAP pretreatment remarkably improved redox homeostasis, both in human embryonic kidney 293 (HEK293) cells and in BALB/c mice...

Group A streptococci (GAS) cause 20-30% of pediatric pharyngitis episodes, which are a major cause of ambulatory care visits. Therefore, a strategy to prevent GAS dissemination in children could significantly benefit public healthcare. Contextually, we assessed the possibility of employing alternative food-grade strategies to be used with the oral probiotic L. helveticus MIMLh5 for the prevention of pharyngeal infections. First, we demonstrated through an antagonism-by-exclusion assay that guaran may potentially prevent S...

Previous work on the computer simulation of edible fats and oils showed that triglyceride crystalline nanoplatelets (CNPs) aggregated into cylindrical structures dubbed "TAGwoods". This was experimentally verified using Ultra Small Angle X-ray Scattering experiments. In this paper, the aggregation of these TAGwoods was studied using the fluid simulation technique, Dissipative Particle Dynamics. The intent was to predict the TAGwood aggregation structures which arise via the application of a series of shear rates, [small gamma, Greek, dot above]...

Mango leaf tea has been traditionally used by different cultures to reduce inflammation in the body. There is evidence that chronic inflammation increases the risk of cancer. This study investigates the antitumoural effects of pressurized mango leaf extracts on minimally (MCF7) and highly invasive (MDA-MB-231) breast cancer cells as well as on non-tumourigenic cells (MCF10). Extracts showed protective properties against oxidation and cytotoxic effects against breast cancer cell lines, causing minor damage to non-carcinogenic cells...

The beneficial effects of consumption of berry fruits on a range of chronic diseases has been attributed (at least in part) to the presence of unique phytochemicals. Recently, we identified novel ursolic acid-based triterpenoid glycosides (TTPNs) in raspberry fruit and demonstrated their survival in human ileal fluids after feeding which confirmed their colon-availability in vivo. In this paper, in vitro digestion studies demonstrated that certain TTPNs were stable under gastrointestinal conditions and confirmed that these components may have been responsible for bioactivity noted in previous studies...

Constipation is one of the most common gastrointestinal complaints worldwide. The aim of this study was to determine whether edible bifidobacteria (Bifidobacterium longum, B. infantis, B. animalis, B. bifidum, B. adolescentis or B. breve) exhibit interspecies differences in alleviating constipation induced by loperamide in BALB/c mice and to analyse the main reasons for the interspecies differences. BALB/c mice were given bifidobacteria by gavage once per day for 8 days. The primary outcome measures, which included related constipation indicators, and the secondary outcome measures, which included changes in the concentration of short-chain fatty acids in faeces and changes in the faecal flora, were used to evaluate the therapeutic effects of the edible bifidobacteria on constipation...

Edible mushrooms have been considered as a good source of bioactive components with various health benefits. Our previous study demonstrated the identity of a novel protein from Pleurotus eryngii, namely PEP, and its anti-inflammatory activities. Herein, we further determined the inhibitory effects of PEP against colon cancer cells. PEP suppressed the proliferation of human and murine colon cancer HCT116 and MC38 cells in a dose and time-dependent fashion, while it showed no inhibitory effect on normal human colonic myofibroblasts CCD-18Co at the same concentrations tested...

Blackberry anthocyanins provide attractive color and antioxidant activity. However, anthocyanins degrade during juice processing and storage, so maintaining high anthocyanin concentrations in berry juices may lead to greater antioxidant and health benefits for the consumer. This study evaluated potential additives to stabilize anthocyanins during blackberry juice storage. The anthocyanin stabilizing agents used were: glutathione, galacturonic acid, diethylenetriaminepentaacetic acid and tannic acid, which were added at a level of 500 mg L(-1)...

Gut microbiota may play a role in the pathogenesis of NAFLD. We investigated whether tomato juice consumption for 5 weeks could ameliorate high-fat diet-induced alterations in certain intestinal bacterial groups and products arising from their metabolism (short-chain fatty acids and microbial phenolic catabolites). For this, we used a rat model with NAFLD induced by a high-fat diet, involving four experimental groups: NA (standard diet and water), NL (standard diet and tomato juice), HA (high-fat diet and water) and HL (high-fat diet and tomato juice)...

Several previous meta-analyses show a consistent inverse association between nut consumption and all-cause mortality, but the associations with cause-specific mortality remain uncertain. A recent meta-analysis on nut consumption and multiple health outcomes combined incidence and mortality outcomes across most of the analyses, which may have introduced heterogeneity across studies. We conducted an updated meta-analysis to evaluate the nut-mortality association. We searched PubMed and EMBASE and we contacted authors for additional data...
