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. […]

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 […]

Influence of Post‐Harvest Moisture on Roasted Almond Shelf Life and Consumer Acceptance.

Background: Sweet almonds (Prunus dulcis) harvest weights have significantly increased to meet consumer demand and now exceed processing facility capabilities. Crops are stockpiled for longer periods of time increasing the probability of moisture exposure. Wet almonds can be mechanically dried prior to processing; however, it is unclear how this practice influences lipid oxidation, shelf-life and consumer […]
