Species of Aspergillus, Penicillium and Alternaria are major contributors to fruit and vegetable decay and to mycotoxin production during various stages of pathogenesis. The mycotoxins most commonly associated with fruits and vegetables and their products are aflatoxins, patulin, ochratoxin A and Alternaria toxins. Naturally occurring aflatoxins are found in fruits of tropical and subtropical r...

Todays, parallel to growing in acceptance of functional products, various additives are used to improve the characteristics of functional food products. The coenzyme Q10 is an essential component for energy conversion and production of adenosine triphosphate (ATP) in the membranes of all body cells and organelles, especially the inner mitochondrial membrane is found. Coenzyme Q10 plays a vital ...

A diet rich in fruits and vegetables, and a grape-derived compound, resveratrol, have been linked to a reduced incidence of colon cancer. In vitro and in vivo, resveratrol suppresses Wnt signaling, a pathway constitutively activated in over 85 % of colon cancers.Thirty participants were placed on a low resveratrol diet and subsequently allocated to one of three groups ingesting 1/3-to-1 lb (0.1...

Wine is an amazingly complex natural product that requires dedicated scientists to resolve many of its mysteries. Traditional synthetic organic chemistry and modern analytical techniques are powerful tools at the disposal of wine chemists who tackle the complexities of wine in order to improve scientific understanding and provide practical solutions to industry. Part of this quest for knowledge...

Food adulteration and mislabeling may pose potential health risks and trust issues to consumers, particularly for high-valued wine products. The current analytical methods and anticounterfeit labeling techniques are insufficient to determine the identity and point of origins for these products. This application note describes a metabolomic profiling method to trace the origins of wine products ...

The effects of grape seeds extract and grape peels extract prepared from grape pomace on the activity of antioxidant enzymes, degree of lipid peroxidation in serum and liver tissue were investigated in rabbits fed on high cholesterol diet. New Zealand white rabbits were divided as follows ; 1) NOR (normal group); 2) CHOL (cholesterol group); 3) GSH (cholesterol + grape seed extract group); 4) G...

BACKGROUND Inflammation and pain associated with temporomandibular joint disorder, a chronic disease that affects 15% of the adult population, involves activation of trigeminal ganglion nerves and development of peripheral and central sensitization. Natural products represent an underutilized resource in the pursuit of safe and effective ways to treat chronic inflammatory diseases. The goal of ...

BACKGROUND Feeding polyphenol-rich plant products has been shown to increase the gain:feed ratio in growing pigs. The reason for this finding has not yet been elucidated. In order to find the reasons for an increase of the gain:feed ratio, this study investigated the effect of two polyphenol-rich dietary supplements, grape seed and grape marc meal extract (GSGME) or spent hops (SH), on gut morp...

Oral allergy syndrome (OAS) is occasionally observed following consumption of raw fruits in allergic adults. Since this phenomenon was commonly reported in Khorasan province of Iran; we intended to check if common diagnostic tests could be applied for differential diagnosis of OAS to grapes. IgE reactivity of 84 patients with OAS to grape and 34 patients with OAS to other fruits were analyzed b...
