Near-infrared hyperspectral imaging evaluation of Fusarium damage and DON in single wheat kernels
(Elsevier, 2022-07-19)Fusarium is a DON producing filamentous fungi which commonly infects small grain cereals. Near-Infrared Hyperspectral Imaging (HSI-NIR) is considered for its potential to manage this contamination, as it uses spatial ... -
Near-infrared hyperspectral imaging for deoxynivalenol and ergosterol estimation in wheat samples
(Elsevier, 2020-09-30)The present study aimed to evaluate the use of hyperspectral imaging (HSI)-NIR spectroscopy to assess the presence of DON and ergosterol presence in wheat samples through prediction and classification models. To achieve ... -
New mycotoxin adsorbents based on tri-octahedral bentonites for animal feed
(Elsevier, 2019-07-21)In the present work different clays have been characterized according to their mycotoxins adsorbent ability. Firstly, 27 bentonite clays from different geographical origins were evaluated, at 0.02% w/v, using an in vitro ... -
Novel and efficient biotechnological approach to produce 2,5-diformylfuran from biomass-derived 5-hydroxymethylfurfural
(American Chemical Society, 2021)The preparation of compounds of interest from biomass-derived 5-hydroxymethylfurfural (HMF) has attracted considerable attention. One such compound is 2,5-diformylfuran (DFF), obtained through oxidation of the hydroxyl ... -
Novel processing technologies as compared to thermal treatment on the bioaccessibility and caco‑2 cell uptake of carotenoids from tomato and kale-based juices
(American Chemical Society, 2019)This research aimed to measure the impact of novel food processing techniques, i.e., pulsed electric field (PEF) and ohmic heating (OH), on carotenoid bioaccessibility and Caco-2 cell uptake from tomato juice and high-pressure ... -
Novel technologies to improve food safety and quality
(Elsevier, 2019)The demand for fresh, healthy, convenient and safe foods has prompted the development of nonthermal technologies in the food area. Numerous investigations in high-hydrostatic pressures, pulsed electric fields, ultrasound, ... -
Les noves actituds dels consumidors: una visió integral de la producció ecològica
(Associació Catalana de Ciències de l’Alimentació, 2014)En els darrers temps, la consciència cada copmés gran dels consumidors coma agents actius de la cadena alimentària ha comportat canvis profunds a tots els seus nivells, des del productor fins alminorista.Diverses tendències ... -
Occurrence and dietary exposure assessment to Enniatin B through consumption of cereal-based products in Spain and the Catalonia Region
(MDPI, 2023)Enniatin B (ENNB) is a mycotoxin produced by moulds from the Fusarium genera and its toxic effects are still not fully elucidated, hence a safe reference exposure value has not been established yet. ENNB is the most prevalent ... -
Occurrence of Alternaria mycotoxins and quantification of viable Alternaria spp. during the food processing of tomato products in Spain
(Wageningen Academic Publishers, 2018-05-15)The occurrence of two Alternaria mycotoxins, alternariol (AOH) and alternariol monomethyl ether (AME) and the presence of conidia from Alternaria spp., were investigated throughout the food production chain of two businesses, ... -
Occurrence of selected viral and bacterial pathogens and microbiological quality of fresh and frozen strawberries sold in Spain
(Elsevier, 2019-10-23)Strawberry production and exports have been increasing in Spain in recent decades. However, little information is available about their microbiological quality. Due to the growing concern about the microbial safety of these ... -
