Conversion of waste animal bones into porous hydroxyapatite by alkaline treatment: effect of the impregnation ratio and investigation of the activation mechanism
(Springer, 2015-08-06)Microporous biochars, mainly composed by hydroxyapatite (HAp), were prepared from animal waste bones. In this study, a three-step procedure including pre-pyrolysis, chemical treatment with NaOH, KOH and K2CO3, and pyrolysis ... -
Critical environmental and genotypic factors for Fusarium verticillioides infection, fungal growth and fumonisin contamination in maize grown in northwestern Spain
(Elsevier B.V., 2014)In northwestern Spain, where weather is rainy and mild throughout the year, Fusarium verticillioides is the most prevalent fungus in kernels and a significant risk of fumonisin contamination has been exposed. In this study, ... -
Cuticular wax composition of ʻCelesteʼ and ʻSomersetʼ cherry fruit
(International Society for Horticultural Science (ISHS), 2017)The cuticular layer plays an important role in protecting fruits against water loss and invasive microorganisms and insects, both during on-tree development and postharvest storage. There is also experimental evidence that ... -
Cytotoxicity of the mycotoxins deoxynivalenol and ochratoxin A on Caco-2 cell line in presence of resveratrol
(Elsevier, 2015-06-19)Exposure to mycotoxins through dietary food intake involves a highly complex scenario where co-contamination of different mycotoxins has been frequently demonstrated. On the other hand, the effect of the interaction of ... -
Decontamination of fresh-cut broccoli with a water–assisted UV-C technology and its combination with peroxyacetic acid
(Elsevier, 2018)The effectiveness of a water-assisted UV-C (WUV) technology for the decontamination of fresh-cut broccoli from conventional and organic agricultural practices was evaluated as an alternative to chlorine sanitation. Several ... -
Decontamination of Listeria innocua from fresh-cut broccoli using UV-C applied in water or peroxyacetic acid, and dry-pulsed light
(Elsevier, 2019-03)The efficacy of two irradiation technologies: Ultraviolet-C light (UV-C), applied in water or in diluted peroxyacetic acid, and dry-pulsed light (PL) for the inactivation and growth inhibition of Listeria innocua in fresh-cut ... -
Deoxynivalenol in cereal-based baby food production process. A review
(Elsevier, 2019-02)Deoxynivalenol (DON) is one of the highest occurring mycotoxin of Fusarium species. Its presence in cereal-based infant foods is extremely undesirable, especially considering the increased sensitivity of this population ... -
Detection and quantification by PCR assay of the biocontrol agent Pantoea agglomerans CPA-2 on apples
(Elsevier B.V., 2014)The registration of biological control agents requires the development of monitoring systems to detect and quantify the agent in the environment Pantoea agglomerans CPA-2 is an effective biocontrol agent for postharvest ... -
Determination of aflatoxins, deoxynivalenol, ochratoxin A and zearalenone in wheat and oat based bran supplements sold in the Spanish market
(Elsevier, 2013)The main objective of this study was to assess the exposure of Catalonian (Spain) population to AFs. Thus, two sub-objectives were considered: 1) to assess the occurrence of AFs in food marketed in Catalonia, and 2) to ... -
Determination of the iodine value of biodiesel using 1H NMR with 1,4-dioxane as an internal standard
(Elsevier, 2010)Iodine values (IVs) of some biodiesel samples were analyzed using both 1H NMR and a standard iodometric method. 1H NMR was carried out with and without 1,4-dioxane as an internal standard (IS). The results obtained using ... -
Development of a fresh-cut product based on pears and the subsequent evaluation of its shelf life under commercial conditions and after a cold chain break
(Science and Education Publishing, 2016)Processing of pears as a fresh-cut product could offer added value and introduce a product into the market that offers greater convenience and health benefits for consumers. Cultivar selection is one of the most important ... -
Development of a SCAR marker and a strain-specific genomic marker for the detection of the biocontrol agent strain CPA-8 Bacillus amyloliquefaciens (formerly B. subtilis)
(WileyAssociation of Applied Biologists, 2016)In this work, reliable tools were developed to detect and identify the biocontrol strain CPA-8 using DNA amplification techniques. As a first approach, the RAPD (random amplified polymorphic DNA) technique was applied ... -
Development of PMA real-time PCR method to quantify viable cells of Pantoea agglomerans CPA-2, an antagonist to control the major postharvest diseases on oranges
(Elsevier B.V., 2014)Dilution plating is the quantification method commonly used to estimate the population level of postharvest biocontrol agents, but this method does not permit a distinction among introduced and indigenous strains. Recently, ... -
Development, physical stability and bioaccessibility of β-carotene-enriched tertiary emulsions
(Elsevier, 2019-10-31)The aim of this study was to develop a β-carotene-enriched tertiary emulsion (lactoferrin/alginate/ε-poly-L-lysine). Then, its physical stability as well as β-carotene content under external stresses (temperature, pH and ... -
Differences in free amino acid profile of non-thermally treated tomato and strawberry juices
(Elsevier, 2013)The amino acids profiles of tomato and strawberry juices subjected to high intensity pulsed electric fields (HIPEF) treatment were evaluated and compared to those of thermally treated juices. Both HIPEF and thermal treatments ... -
