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, ... -
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 ... -
DNA-based methodologies for the quantification of live and dead cells in formulated biocontrol products based on Pantoea agglomerans CPA-2
(Elsevier B.V., 2015)Pantoea agglomerans strain CPA-2 is an effective biocontrol agent (BCA) against the major postharvest pathogens present on pome and citrus fruits. Dehydration, such as freeze-drying, spray-drying and fluidized bed drying ... -
DNA-based methodologies to detect and quantify the postharvest biocontrol agent Pantoea agglomerans CPA-2 applied on oranges
(International Society for Horticultural Science, 2016-11)Pantoea agglomerans strain CPA-2 is an effective biocontrol agent (BCA) for postharvest diseases of citrus and pome fruits. However, for registration purposes and to implement their use as effective control strategy, it ... -
Eating quality and health-promoting properties of two sweet cherry (Prunus avium L.) cultivars stored in passive modified atmosphere
(SAGE Publications, 2015)Two sweet cherry cultivars ('New Star' and 'Sweet Heart') were chosen to explore the impact of passive modified atmosphere packaging on the eating quality and health-promoting properties of fruit. Packaged and unpackaged ... -
Effect of host and Monilinia spp. variables on the efficacy of radio frequency treatment on peaches
(Elsevier B.V., 2014-01)Brown rot caused by Monilinia spp. is the most important postharvest disease of stone fruit. Currently, no chemical fungicides are allowed in the European Union to be applied to stone fruit after harvest. In previous work, ... -
Effect of pre-harvest conditions and postharvest storage time on the quality of whole and fresh-cut calçots (Allium cepa L.)
(Elsevier, 2019-01-23)Pre-harvest conditions such as cultivar, cultivation site and planting time could affect the storability, quality and shelf-life of fruit and vegetables. The influence of onion cultivar, cultivation site and planting time ... -
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 ... -
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 ... -
Effectiveness of a bacteriophage in reducing Listeria monocytogenes on fresh-cut fruits and fruit juices.
(Elsevier Ltd., 2014)Listeria monocytogenes is a serious foodborne pathogen and new strategies to control it in food are needed. Among them, bacteriophages hold attributes that appear to be attractive. The objective of this study was to ... -
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 ... -
Efficacy of chlorine, peroxyacetic acid and mild-heat treatment on the reduction of natural microflora and maintenance of quality of fresh-cut calçots (Allium cepa L.)
(Elsevier, 2018)Calçots are the immature floral stems of the second-year onion (Allium cepa L.) resprouts with economic importance in Spain. The effect of sodium hypochlorite, peroxyacetic acid and mild heat treatment on the microbiological, ... -
