Differential contribution of the two major polygalacturonases from Penicillium digitatum to virulence towards citrus fruit
(Elsevier, 2018-10)The fungus Penicillium digitatum is the causal agent of the citrus green mould, the major postharvest diseases of citrus fruit. Lesions on the surface of infected fruits first appear as soft areas around the inoculation ... -
Biopreservation of fresh-cut pear using Lactobacillus rhamnosus GG and effect on quality and volatile compounds
(Elsevier, 2018-01)In recent years, the consumption of minimally processed fruit has increased. However, unfortunately, these products could be an appropriate vehicle for the transmission of foodborne pathogens. In this study, the antagonistic ... -
Evaluation of biocontrol capacity of Pseudomonas graminis CPA-7 against foodborne pathogens on fresh-cut pear and its effect on fruit volatile compounds
(Elsevier, 2018)The application of microorganisms to control the growth of foodborne pathogens is an alternative to the use of chemical additives. In this work, Pseudomonas graminis CPA-7 was tested as a biocontrol agent against Salmonella ... -
Effects of thermal and non-thermal processing of cruciferous vegetables on glucosinolates and its derived forms
(Springer, 2018-06)Brassica vegetables, which include broccoli, kale, cauliflower, and Brussel sprouts, are known for their high glucosinolate content. Glucosinolates and their derived forms namely isothiocyanates are of special interest in ... -
Physiochemical and nutritional characteristics, bioaccessibility and sensory acceptance of baked crackers containing broccoli co‐products
(Wiley, 2018)The effects of the inclusion of broccoli co‐products into crackers on the bioaccessibility as well as their overall physical and nutritional quality were evaluated. Crackers were formulated using a 12.5 or 15.0% flour ... -
Effect of thermosonication on the bioaccessibility of antioxidant compounds and the microbiological, physicochemical, and nutritional quality of an anthocyanin-enriched tomato juice
(Springer, 2018)The aim of this study was to assess the potential of thermosonication as a strategy to obtain safe and high-quality tomato juice enriched in anthocyanins, formulated using strawberry processing co-products. Incorporation ... -
Effect of steaming and sous vide processing on the total phenolic content, vitamin C and antioxidant potential of the genus Brassica
(Elsevier, 2018-06)This study evaluated the effect of thermal processing on the antioxidant potential, vitamin C, and total phenolic content of various parts, including edible co-products, of several Brassica vegetables. Overall, no significant ... -
Postharvest heat and CO2 shocks induce changes in cuticle composition and cuticle-related gene expression in 'October Sun' peach fruit
(Elsevier, 2019)Fruit cuticles influence greatly postharvest quality of produce. Yet, few published studies have addressed changes in cuticle composition and related gene expression from a postharvest perspective, particularly for fruit ... -
Physicochemical and rheological properties of gum seed and pulp from Hymenaea courbaril L.
(Taylor & Francis, 2018-11-22)The aim of this work was to isolate pulp (PH) and seed hydrocolloids (SH) of the fruit of Hymenaea corbaril L. and determinate chemical, functional and rheological properties, as a proposal of a new attractive product ... -
Caracterización funcional de almidones nativos obtenidos de papas (Solanum phureja) nativas peruanas
(Universidad Nacional de Trujillo, 2015)Existen muchas variedades de papas nativas cultivadas en diferentes localidades del Perú, generalmente para el auto consumo del agricultor. Sin embargo, la posibilidad de su uso comercial ha originado este trabajo con el ... -
Fate of zearalenone, deoxynivalenol and deoxynivalenol-3-glucoside during malting process
(Elsevier, 2019-01)Malting was simulated using two different batches of barley as raw material: a naturally contaminated batch and laboratory inoculated (with a deoxynivalenol (DON) and zearalenone (ZEA) producing Fusarium graminearum strain) ... -
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 ... -
The role of mycotoxins in the human exposome: Application of mycotoxin biomarkers in exposome-health studies
(Elsevier, 2018-09-19)Mycotoxins are secondary metabolites produced by fungi that may contaminate different foods intended for human consumption, resulting in a widespread exposure worldwide. The novel exposome paradigm has the ambition to ... -
Impact of Pseudomonas graminis strain CPA-7 on respiration and ethylene production in fresh-cut ‘Golden delicious’ apple according to the maturity stage and the preservation strategy
(Elsevier, 2018)The effect of the biocontrol agent (BCA) Pseudomonas graminis CPA-7 on the accumulation of CO2 and ethylene (C2H4) in fresh-cut apples at two maturity stages was evaluated in refrigerated conditions. Factors involved in ... -
