Risk management towards food safety objective achievement regarding to mycotoxins in pistachio: the sampling and measurement uncertainty issue
(Elsevier, 2013)The emerging risk management metrics, FSO, PO and PC, were applied to the aflatoxins (AFs) and ochratoxin A (OTA) determination in 8 commercial lots of pistachio. In order to determine the sampling uncertainty, two sampling ... -
Single vs multiple-spore inoculum effect on growth kinetic parameters and modeled probabilities of growth and aflatoxin B1 production of Aspergillus flavus on pistachio extract agar
(Elsevier, 2017)The objective of the present study was to assess the differences in modeled growth/AFB1 production probability and kinetic growth parameters for Aspergillus flavus inoculated as single spores or in a concentrated ... -
Solvent-free biocatalytic interesterification of acrylate derivatives
(Elsevier, 2012)The ability of diverse commercial lipases and whole cells (fungal resting cells) to synthesise allyl and dichloropropyl acrylate from allyl dodecanoate through an interesterification process is presented. The process was ... -
Stability and kinetics of leaching of deoxynivalenol, deoxynivalenol-3-glucoside and ochratoxin A during boiling of wheat spaghettis
(Elsevier, 2016)The stability of deoxynivalenol (DON), deoxynivalenol-3-glucoside (DON-3-glucoside) and ochratoxin A (OTA) during spaghetti production and cooking was investigated. Initial mycotoxin concentration, boiling time and use of ... -
Stability of alternariol and alternariol monomethyl ether during food processing of tomato products
(Elsevier, 2018)The stability of two Alternaria mycotoxins, alternariol (AOH) and alternariol monomethyl ether (AME), has been investigated during the food processing of tomato products simulating commercial processing conditions. The ... -
Stability of DON and DON-3-glucoside during baking as affected by the presence of food additives
(Taylor & Francis, 2018)The mycotoxin deoxynivalenol (DON) is one of the most common mycotoxins of cereals worldwide, and its occurrence has been widely reported in raw wheat. The free mycotoxin form is not the only route of exposure; modified ... -
Stability of DON and OTA during the breadmaking process and determination of process and performance criteria
(Elsevier, 2014)The fate of deoxynivalenol (DON) and ochratoxin A (OTA) during the breadmaking process was studied. In particular, toxin content was analysed in mixed baking ingredients before kneading, after fermentation and proofing, ... -
Standardisation of near infrared hyperspectral imaging for quantification and classification of DON contaminated wheat samples
(Elsevier, 2019-12-23)Near infrared hyperspectral imaging (HSI-NIR) is considered a promising technique able to replace time-con- suming, costly and destructive classic methods to predict and classify deoxynivalenol (DON) contaminated wheat ... -
Standardization of near infrared hyperspectral imaging for wheat single kernel sorting according to deoxynivalenol level
(Elsevier, 2020-11-28)The spatial recognition feature of near infrared hyperspectral imaging (HSI-NIR) makes it potentially suitable for Fusarium and deoxynivalenol (DON) management in single kernels to break with heterogeneity of contamination ... -
Steaming and sous-vide: Effects on antioxidant activity, vitamin C, and total phenolic content of Brassica vegetables
(Elsevier, 2018-05-28)The present study evaluated the effect of thermal processing on the colour, antioxidant activity, vitamin C content, and total phenols of six Brassica vegetables. The landrace Grelo was the best source of total phenols ... -
Strategies to reduce microbial risk and improve quality of fresh and processed strawberries: A review
(Elsevier, 2019-03)Strawberries are one of the most important fruits in the Mediterranean diet and have been widely investigatedfor their nutritional and nutraceutical properties. Concern about the safety of fresh and processed strawberrieshas ... -
Strawberry sanitization by peracetic acid washing and its effect on fruit quality
(Elsevier, 2019-05-15)The risk posed by outbreaks associated with strawberries together with the safety issues of by-products from chlorine disinfection in the fruit industry has led to a search for alternative sanitizers. The disinfection ... -
Studies on the biocontrol mechanisms of Pseudomonas graminis strain CPA-7 against food-borne pathogens in vitro and on fresh-cut melon
(Elsevier, 2017)The present study was aimed at gaining insight into the mode of action of the antagonistic bacteria Pseudomonas graminis CPA-7, which has been previously identified as an effective biocontrol agent against Listeria ... -
Studies on the interaction between grape-associated filamentous fungi on a synthetic medium
(Elsevier, 2007)Eleven fungi isolated from grapes and sun-dried grapes (Alternaria alternata, Cladosporium herbarum, Eurotium amstelodami, Penicillium janthinellum, P. decumbens, Trichoderma harzianum, Candida sp., Aspergillus carbonarius ... -
Study of the catabolism of thyme phenols combining in-vitro fermentation and human intervention.
(American Chemical Society, 2014)The gut metabolism of four thyme phenolics (monoterpenes thymol and carvacrol, rosmarinic acid, and eriodictyol) was evaluated in vitro. After the in vitro transformations of the individual phenols had been studied, the ... -
