The need to revisit ochratoxin A risk in light of diabetes, obesity, and chronic kidney disease prevalence.
Ochratoxin A (OTA) is a mycotoxin, or fungal toxin, that contaminates multiple foodstuffs worldwide. Affected commodities include oats, wheat, maize, barley, raisins and other dried vine fruits, wine, beer, coffee, and cocoa. Although OTA has been shown to cause kidney disease, including kidney cancer, in multiple animal species, the impact of dietary OTA on human […]
Sun dried Corinthian currant (Vitis Vinifera L., var. Apyrena) simple sugar profile and macronutrient characterization.
Corinthian currant simple sugar profile was determined by high-pressure liquid chromatography coupled with refractive index detection; the content in other macroconstituents was also assessed. Corinthian currants analyzed were obtained over three consecutive crop years, while the effect of cultivation area altitude was also evaluated. Sugar extraction was optimized with respect to solvent, process, and time. […]
Determination of acrylamide in dried fruits and edible seeds using QuEChERS extraction and LC separation with MS detection.
Acrylamide is a carcinogenic and neurotoxic process contaminant that is generated from food components during heat treatment, while it is absent in raw foodstuffs. Its level in food arouses great concern. A method for acrylamide extraction and determination in dried fruits (dried prunes and raisins) and edible seeds (almonds, hazelnuts, peanuts, pine nuts, pistachios, and […]
Evaluation of the Anti-Inflammatory Activity of Raisins (Vitis vinifera L.) in Human Gastric Epithelial Cells: A Comparative Study.
Raisins (Vitis vinifera L.) are dried grapes largely consumed as important source of nutrients and polyphenols. Several studies report health benefits of raisins, including anti-inflammatory and antioxidant properties, whereas the anti-inflammatory activity at gastric level of the hydro-alcoholic extracts, which are mostly used for food supplements preparation, was not reported until now. The aim of this study was to […]
Effects of different drying treatments on fungal population and ochratoxin A occurrence in sultana type grapes.
This study aimed to determine the changes in mould and ochratoxin A (OTA) occurrence in sultanas under three different conventional drying conditions. Five different vineyards were chosen, and the three different treatments were applied to these grapes while drying. At the end of the drying process, total mould and black aspergilli (BA) populations in the […]
Non-polyphenolic compounds of a specific kind of dried grape (Maviz) inhibit memory impairments induced by beta-amyloid peptide.
OBJECTIVES: Although grape has been recently the topic of many investigations, Maviz (a kind of dried one) has remained neglected. The aim of this study was to assess anti-Alzheimer activity of Maviz. METHODS: To reach this goal, total phenolic content (TPC) of ethanolic (Eth) and aqueous (Aq) extracts were determined and radical scavenging activity was […]
Pairing nuts and dried fruit for cardiometabolic health.
Certain dietary patterns, in which fruits and nuts are featured prominently, reduce risk of diabetes and cardiovascular disease. However, estimated fruit consumption historically in the U.S. has been lower than recommendations. Dried fruit intake is even lower with only about 6.9 % of the adult population reporting any consumption. The 2015 Dietary Guidelines Advisory Committee […]
Fruit and Vegetable Consumption and the Incidence of Hypertension in Three Prospective Cohort Studies
Increased fruit and vegetable intake lowers blood pressure in short-term interventional studies. However, data on the association of long-term intake of fruits and vegetables with hypertension risk are scarce. We prospectively examined the independent association of whole fruit (excluding juices) and vegetable intake, as well as the change in consumption of whole fruits and vegetables, […]
A Novel Hyperspectral Feature-Extraction Algorithm Based on Waveform Resolution for Raisin Classification
Near-infrared hyperspectral imaging technology was adopted in this study to discriminate among varieties of raisins produced in Xinjiang Uygur Autonomous Region, China. Eight varieties of raisins were used in the research, and the wavelengths of the hyperspectral images were from 900 to 1700 nm. A novel waveform resolution method is proposed to reduce the hyperspectral […]
Ochratoxin A in dried grapes in Hamadan province, Iran.
The occurrence of ochratoxin A (OTA) in dried grapes was surveyed in this study. Sixty-six samples of dried grapes (40 currants, 16 sultanas and 10 raisins) were collected from dried grapes factories in Hamadan province, Iran, from October 2012 to March 2013. High-performance liquid chromatography (HPLC) was used to determine OTA in these samples. OTA […]
