Ochratoxins are polyketide derived fungal secondary metabolites with nephrotoxic, immunosuppressive, teratogenic, and carcinogenic properties. Ochratoxin-producing fungi may contaminate agricultural products in the field (preharvest spoilage), during storage (postharvest spoilage), or during processing. Ochratoxin contamination of foods and feeds poses a serious health hazard to animals and humans. Several strategies have been investigated for lowering the ochratoxin content in agricultural products. These strategies can be classified into three main categories: prevention of ochratoxin contamination, decontamination or detoxification of foods contaminated with ochratoxins, and inhibition of the absorption of consumed ochratoxins in the gastrointestinal tract. This paper gives an overview of the strategies that are promising with regard to lowering the ochratoxin burden of animals and humans.

    ABSTRACT: A highly integrated monolithic microwave integrated circuit (MMIC) that acts as the core of the RF section of a synthesized source is developed using commercially available 0.2-μm pseudomorphic high electron mobility transistor (PHEMT) technology. Measured performance is shown up to 18 GHz. The same system architecture is able to produce synthesized output through 40 GHz with modifications of some critical building blocks of the chip. The chip performs all the frequency selection and tuning functions. It has more than 30 RF blocks integrated on an area of 4.27×4.68 mml. Some individual blocks operate through 40 GHz

    ABSTRACT: Global occurrence of Ochratoxin-A (OTA) in coffee has gained enormous apprehension in the coffee world trade market. Biological control has been proposed as an alternative for chemicals to reduce mold growth and mycotoxin production. It is hypothesized that yeast species can inhibit ochratoxigenic molds and OTA production in coffee. To test this hypothesis, we undertook a field study with natural and artificial contamination trials, wherein commercial yeast (Saccharomyces cerevisiae) were used during processing of arabica parchment (AP), arabica cherry (AC), robusta parchment (RP) and robusta cherry (RC) coffee. The yeast strain was inoculated to arabica and robusta coffee at a concentration of 0.5%, 1%, 1.5% and 2% with appropriate control. Inoculation of yeast during coffee processing was found to significantly reduce total mold incidence (Aspergillus niger, Aspergillus ochraceus) and OTA contamination in both the parchment and cherry of arabica and robusta without affecting the cup quality in both natural and artificial contamination trials. Significant correlation occurred in the incidence of A. ochraceus and OTA contamination in AP (r = 0.99), AC (r = 0.93), RP (r = 0.93) and RC (r = 0.94) as compared to total molds and incidence of A. niger and OTA level. The results of the present study clearly indicates a promising antagonistic and biocontrol potential of commercial yeasts in reducing the ochratoxigenic mold incidence and OTA contamination in coffee beans during on-farm processing. Use of yeast culture in coffee processing was found to be an affordable and cost effective approach in the management of A. ochraceus and OTA in parchment and cherry coffee preparation.

    ABSTRACT: The effectiveness of modified nanodiamonds (NDs) for the adsorption of mycotoxins, aflatoxin B1 (AfB1) and ochratoxin A (OTA), are investigated in this paper. Binding and release mechanisms of the mycotoxins were addressed using an assortment of NDs modified by different surface treatments, including carboxylation, hydrogenation and hydroxylation, followed by isolating NDs of different sizes. Results indicate that AfB1 adsorption on NDs is directly related to aggregate size, whereas OTA adsorption is primarily centered upon electrostatic interactions that depend on the types of surface functional groups on the ND. Findings show that modified NDs with small aggregation sizes (∼40 nm) have greater adsorption capacities for AfB1 than yeast cells walls and untreated NDs from various vendors, but comparable to activated charcoal. In OTA studies, positively charged NDs outperformed clay minerals, which are well-known and efficient sorbents for mycotoxins. Furthermore, ND adsorption capacities can be preserved in a wide range of pH.
