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 […]
Formulation, development and characterization of a novel functional fruit snack based on fig (Ficus carica L.) coated with sugar-free chocolate.
The aim of the present investigation was to explore the possibility of developing a fruit snack formulation based on dried fig powder and chocolate-coated. Dried Fig (Ficus carica L.) powder with a maximum particle size of 354 μm and the lowest compaction force was formulated as the core. Persian gum was prepared at the concentrations […]
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 […]
Determination of the elemental composition and antioxidant properties of dates (Phoenix dactyliferia) originated from different regions.
Due to the growing interest in running a healthy life, including the diet a special interest has been put in searching for products that are rich in nutrients, macro and micronutrients and vitamins. Dates are the fruits that meet these requirements and show multidirectional pro-health effects. These fruits are a source of potassium and other […]
AFLA-PISTACHIO: Development of a Mechanistic Model to Predict the Aflatoxin Contamination of Pistachio Nuts.
In recent years, very many incidences of contamination with aflatoxin B1 (AFB1) in pistachio nuts have been reported as a major global problem for the crop. In Europe, legislation is in force and 12 μg/kg of AFB1 is the maximum limit set for pistachios to be subjected to physical treatment before human consumption. The goal of the […]
Ascophyllum Nodosum And Salicylic Acid Mitigate Effects Of Summer Stress Improving Hazelnut Quality.
Background: Difference strategies are needed to mitigate the negative impact or to increment fruit quality. The effect of spraying Kaolin (K), Ascophyllum nodosum (An) and Salicylic acid (SA), in trees with and without irrigation, on quality and sensorial attributes of hazelnut (Grada de Viseu cultivar) was investigated during two consecutive years (2016 and 2017) in a […]
Evaluation of the effect of label attributes over the purchase intention of a cashew nut functional beverage using conjoint analysis.
The package label is an important factor to be evaluated, for constituting the first contact of the product with the consumer, which may exert influence on the purchase intention. Thus, this study identified and evaluated the importance of front label attributes of a new functional beverage made from cashew nut added with mango juice on […]
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 […]
