Residue dissipation, evaluation of processing factor and safety assessment of hexythiazox and bifenazate residues during drying of grape to raisin.

An analytical method for the simultaneous analysis of hexythiazox and bifenazate residues in grape and raisin was validated by liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis. The extraction method involved liquid-liquid extraction with ethyl acetate and dSPE cleanup with primary secondary amine (PSA). The drying of grape to raisin may increase or decrease residues of pesticides. […]

Biologically Active Compounds in Selected Organic and Conventionally Produced Dried Fruits.

A growing demand for organic foods is driven by consumers' perception that they are more nutritious. However, while there is a number of scientific studies showing some superior qualities of organically grown fruit and vegetables, including, i.e., higher content of phenolics, some vitamins and antioxidant activity, scientific research looking into the quality of processed organic […]

Different drying methods of Pistacia Atlantica seeds: Impact on drying kinetics and selected quality properties.

The effect of different drying procedures on the quality characteristics of Pistacia atlantica subsp. kurdica is addressed in this work. Using five different drying methods include microwave, oven (40 and 60°C), sun, and shade, P. atlantica were dried. The variations in moisture content, drying rate, major components of essential oil, and texture property were assessed at the start and at the […]

Effect of blanching on aflatoxin contamination and cross-contamination of almonds.

Blanching of almonds was examined for reducing aflatoxin content of contaminated nuts. Almonds with intact pellicles were spiked with aflatoxin B 1 (AFB 1 ) and blanched at 85°C. Following blanching, almond kernels and pellicles contained 20% and 19% of spiked AFB 1 , respectively. Blanching water contained an additional 41% of spiked AFB 1 […]

Profiles of fungal metabolites including regulated mycotoxins in individual dried Turkish figs by LC-MS/MS.

Fungal metabolites including regulated mycotoxins were identified by a validated LC-MS/MS method in 180 individual Turkish dried figs from 2017 and 2018 harvests. Hand-selected dried figs were subjectively classified based on the extent of fluorescence. Forty-three fungal metabolites including eight EU-regulated mycotoxins were identified and quantified. Figs classified as being uncontaminated mostly did not contain […]

Long-Term, Open-Label Extension Study of the Efficacy and Safety of Epicutaneous Immunotherapy for Peanut Allergy in Children: PEOPLE 3-Year Results.

Background: We previously reported the safety and efficacy of epicutaneous immunotherapy (EPIT™) for peanut allergy (250 μg, daily epicutaneous peanut protein; DBV712 250μg) in a 12-month randomized controlled study (PEPITES) of peanut-allergic children aged 4-11 years. Objective: To assess interim safety and efficacy of an additional 2 years of EPIT from the ongoing (5-year treatment) open-label extension […]

Inactivation of Salmonella and Listeria monocytogenes on dried fruit, pistachio nuts, cornflakes and chocolate crumb using a peracetic acid-ethanol based sanitizer or Advanced Oxidation Process.

Two decontamination methods were evaluated for inactivating a cocktail of Salmonella or Listeria monocytogenes inoculated onto model low moisture foods (LMFs; dried strawberry, dried apple, raisins, chocolate crumb, cornflakes, shell-on or deshelled pistachio nuts). One treatment was based on a peracetic acid-ethanol (PAA-ethanol) sanitizer combination with the other being an Advanced Oxidation Process (AOP) that […]
