Oat and oat-based products are expected to present the highest levels of some Fusarium mycotoxins, such as T-2 HT-2 toxins. The content these trichothecenes has been increasing in oats last few years. Moreover, oat consumption is expanding, so it even more relevant control their mycotoxin at reception food feed companies. Near-infrared hyperspectral imaging (NIR-HSI) considered a promising technique for determining mycotoxins cereals because quicker, cheaper sustainable than conventional...
Antioxidant capacity, quality, and anthocyanin nutrient contents of 106 peach cultivars from different breeding programs were evaluated at the Estació Experimental de Lleida, IRTA (Catalonia, Spain), during two growing seasons (2010 2011). High variability was found among within each quality trait, where scored as best worst. For example, a 5-fold range (2.17-12.07 g malic acid L⁻¹), 6-fold (144.20-711.73 μg Trolox g⁻¹ FW), 11-fold (0.70-11.43 mg cyanidin-3-glucoside kg⁻¹ FW) observed in...
Cuticle composition and structure may be relevant factors affecting the storage potential of fruits, but very few studies have analyzed fruit cuticle from a postharvest perspective. In this work, chemical waxes cutin (major cuticular components) was in samples isolated "Celeste" "Somerset" cherries (Prunus avium L.) after cold at 0 °C. Total amounts per surface unit (μg cm–2) increased along with storage. The triterpene ursolic acid, alkane nonacosane, linoleic β-sitosterol were most...
Abstract BACKGROUND Maize is frequently contaminated with deoxynivalenol (DON) and fumonisins B 1 (FB ) 2 ). In the European Union, these mycotoxins are regulated in maize maize‐derived products. To comply regulations, industries require a fast, economic, safe, non‐destructive environmentally friendly analysis method. RESULTS present study, near‐infrared hyperspectral imaging (NIR‐HSI) was used to develop regression classification models for DON, FB kernels. The best presented following root...
Abstract A multilateral approach that includes both biotic and climatic data was developed to detect the main variables affect ecology population dynamics of woolly apple aphid Eriosoma lanigerum (Hausmann). Crawlers migrated up down trunk mainly from spring autumn horizontal migration through canopy observed May August. Winter temperatures did not kill colonies, root colonies are source reinfestations in Mediterranean areas. Thus, control measures should simultaneously address roots canopy....
Olive (Olea europaea L.) growing has outstanding economic relevance in Spain, the main olive oil producer and exporter world. Fruit skin properties are very relevant for fruit quality, water loss, susceptibility to mechanical damage, rots, infestations, but limited research focus been placed on cuticle of intact fruit. In this work, samples from nine cultivars ("Arbequina," "Argudell," "Empeltre," "Farga," "Manzanilla," "Marfil," "Morrut," "Picual," "Sevillenca") were harvested an...
Here we authenticated single-varietal peach purees and pear juices on the basis of primary metabolite phenolic compound analysis by Proton Nuclear Magnetic Resonance (1H-NMR) Ultra Performance Liquid Chromatography coupled to Photodiode Array Tandem Mass Spectrometry (UPLC-PDA-MS/MS), respectively. After suitable preprocessing, 1H-NMR chromatographic data were evaluated principal component (PCA). The PCA combining from metabolites compounds allowed separation clusters in all cases, allowing...
Summary The colour changes caused by high‐pressure processing at different temperatures of apple juice were investigated. Six varieties used (Braeburn, Fuji, Gala, Golden Delicious, Granny Smith and Red Delicious), searching for the influence variety from two approaches: a kinetic study, finding best model each one them, multivariate study consisting principal component analysis data. Although it had lower initial values, redness ( a* ) was more influenced high pressure than yellowness b* )....
Summary In purees manufacturing from some fruits, problems related to undesirable colours that come fruit skin may arise. this article, the feasibility of using an enzyme preparation reduce colour R ed B artlett pears be used for industrial has been studied. Kinetic models suitably describe changing parameters with treatment time have tested, seeking optimum ones. It was found most appropriated processing conditions discoloration are as follows: 45 °C concentration 5000 ppm and a does not...
