Amyloid beta-peptide (Abeta), a risk of Alzheimer's disease (AD), causes cell death by inflammation and oxidative stress. Red mold rice (RMR) fermented by Monascus species is regarded as cholesterol-lowering functional food in virtue of the metabolite monacolin K identified as lovastatin. In addition, RMR is also demonstrated to express antioxidation ...

The special extract ERr 731 from the roots of rhapontic rhubarb has been regularly prescribed for women with menopausal symptoms since 1993. As its constituents belong to the class of natural hydroxystilbenes, concerns have been raised about possible health risks similar to those known for the estrogenic diethylstilbestrol. To demonstrate ...

The content of phytochemicals has been proposed to contribute to the beneficial effects of a diet rich in fruits and vegetables. One proposed mechanism of action of phytochemicals is down regulation of NF-kappa B activity. This transcription factor is important in inflammatory and immune responses, however aberrant activity of NF-kappa ...

The growth of horticulture industries worldwide has generated huge quantities of fruit wastes (25%-40% of the total fruits processed). These residues are generally a good source of carbohydrates, especially cell wall polysaccharides and other functionally important bioactive molecules such as proteins, vitamins, minerals and natural antioxidants. "Apple pomace" is a ...

Epibiosis or fouling on living organisms can have direct and indirect detrimental effects, in particular on photosynthetic organisms such as seaweeds. It thus seems reasonable to hypothesize that macroalgae have been selected for the presence or induction of antifouling (AF) defences. The red seaweed Cryptonemia seminervis is usually found in ...

The gluten analysis of foods has long had limitations, which have precluded food standards authorities from issuing standards for gluten-free foods based on final gluten content. The Codex Alimentarius and the Food and Drug Administration have taken steps towards such standards in which they favour the R5-enzyme-linked immunosorbent assay for ...

For many years chemical preservatives have been used in food, to act as either antimicrobials or antioxidants or both. In general, consumers regard additive-free foods as safer since preservatives can cause health hazards like asthma and cancer and are suspected to be mutagenic and neurotoxic. The present study was carried ...

Monascus species-fermented red mold rice (RMR) has been regarded as a popular hypolipidemic functional food because it contains monacolin K, an inhibitor of de novo cholesterol synthesis. However, the safety of RMR is always an issue because citrinin is present in RMR and is reported to be hepatotoxic and nephrotoxic. ...

Food protein-derived peptides with antioxidant activity have great potential for use as natural antioxidants in food products. However, neither the structure-activity relationship nor the antioxidant mechanism of peptides is fully understood. Egg yolk phosvitin has been acknowledged to have strongly antioxidant protein owing to its highly phosphorylated form. In this ...

Leachables are chemical entities that migrate spontaneously from the final container closure system, packaging components and/or processing equipment under recommended conditions of product use and storage. Unlike leachables, extractables are generated under exaggerated temperature and time conditions in the presence of an appropriate solvent. Increasing evidence suggests that leachables may ...

Cottonseed could be used as a source of dietary protein for human food production. The cottonseed component, gossypol, is toxic, however, which has limited the potential of cottonseed in human food production. Free gossypol was removed from glanded cottonseed using a two-stage solvent extraction method utilizing aqueous and anhydrous acetone. ...

Purple corn (Zea mays L.) is a rich and economic source of anthocyanin colorants and functional ingredients. However, high levels of anthocyanin-rich waste are generated during processing, reducing the yields and increasing the costs of the final product. This waste has been associated with anthocyanin complexation with tannins and proteins. ...

The measurement of antioxidant activity was limited to soluble components to date. Functional groups, which are bound to insoluble matters, may exert antioxidant activity by a surface reaction phenomenon. This hypothesis was tested on the insoluble matters of foods, food ingredients, and Maillard reaction products (MRPs). Insoluble matters were prepared ...

Generally speaking, when people talk about "hair breakage" they are typically referring to the idea that as they comb or brush their hair, the fibers are elongating and snapping at some weak point in the fiber length. It is well established that as people chemically treat their hair, the keratin ...

BACKGROUND & AIMS: Celiac disease is characterized by activation of HLA-DQ2/DQ8-restricted intestinal gluten-specific CD4(+) T cells. In particular, gluten becomes a better T-cell antigen following deamidation catalyzed by tissue transglutaminase. To date, the only available therapy is represented by adherence to a gluten-free diet. Here, we examined a new enzyme ...

Cinnamomum burmannii Blume (cinnamon stick) from Indonesia is a little-investigated spice. In this study, the antibacterial activity, minimum inhibitory concentration (MIC), and minimum bactericidal concentration (MBC) of cinnamon stick extract were evaluated against five common foodborne pathogenic bacteria (Bacillus cereus, Listeria monocytogenes, Staphylococcus aureus, Escherichia coli, and Salmonella anatum). Cinnamon ...

Levels of obesity-linked non-insulin-dependent diabetes mellitus (NIDDM) and hypertension are highest among indigenous communities in North America. This is linked to changes in dietary pattern towards high calorie foods such as sugar, refined grain flour, and sweetened beverages. Therefore, a return to traditional dietary patterns may help to reduce these ...

Gliadin proteins are primarily responsible for celiac disease. As gliadin is a complex mixture of proteins difficult to solubilize and to extract from food, it is difficult to develop an assay capable of accurate quantization of gliadin in food for celiac patients. In this work, we present an advanced fluorescence ...

BACKGROUND: Coeliac disease is caused by an immune response to gluten. As gluten proteins are proline rich they are resistant to enzymatic digestion in the gastrointestinal tract, a property that probably contributes to the immunogenic nature of gluten. AIMS: This study determined the efficiency of gluten degradation by a post-proline ...

Nutrigenomics seeks to understand the interplay between an individual's genes and their diet. This approach can potentially be harnessed to reduce the incidence or symptoms of chronic diseases, such as inflammatory bowel disease (IBD). It becomes desirable to interrogate the vast number of discrete compounds present in foods for their ...

Quorum sensing (QS) is a cell density dependent expression of species in bacteria mediated by hormone like compounds called autoinducers (AI). Several processes responsible for successful establishment of bacterial infection are mediated by QS. Inhibition of QS is therefore being considered as a new target for antimicrobial chemotherapy. Dietary phytochemicals ...
