An Enterobacteriaceae species isolated from apples controls foodborne pathogens on fresh-cut apples and peaches
Alegre Vilas, Isabel; Viñas Almenar, Inmaculada; Usall i Rodié, Josep; Anguera, Marina; Figge, Marian J.; Abadias i Sero, Mª Isabel (Elsevier, 2012)Currently, chlorine is the most widely used decontaminant in the minimally processed (MP) food industry. However, it does not achieve more than a 1–2 log reduction in bacterial populations. Efficient decontamination of MP ... -
Antagonistic effect of Pseudomonas graminis CPA-7 against foodborne pathogens in fresh-cut apples under simulated commercial conditions
Alegre Vilas, Isabel; Viñas Almenar, Inmaculada; Usall i Rodié, Josep; Abadias i Sero, Mª Isabel; Altisent Rosell, Rosa; Anguera, Marina (Elsevier, 2013)Recently, we reported that the application of the strain CPA-7 of Pseudomonas graminis, previously isolated from apple, could reduce the population of foodborne pathogens on minimally processed (MP) apples and peaches under ... -
Bioconservación frente a patógenos de transmisión alimentaria en frutas y hortalizas mínimamente procesadas
Alegre Vilas, Isabel; Abadias i Sero, Mª Isabel; Colás Medà, Pilar; Collazo Cordero, Cyrelys; Viñas Almenar, Inmaculada (Consejo Superior de Investigaciones Científicas (CSIC), 2020-03)El aumento en la producción y consumo de frutas y hortalizas mínimamente procesadas de los últimos años ha contribuido a incrementar las toxiinfecciones alimentarias asociadas al consumo de productos vegetales frescos. ... -
Changes in the quality and antioxidant properties of fresh-cut melontreated with the biopreservative culture Pseudomonas graminis CPA-7 during refrigerated storage
Plaza, Lucía; Altisent Rosell, Rosa; Alegre Vilas, Isabel; Viñas Almenar, Inmaculada; Abadias i Sero, Mª Isabel (Elsevier B.V., 2016)The strain CPA-7 of Pseudomonas graminis, isolated from apple by our group, was reported to reduce the population of foodborne pathogens in minimally processed fruit. The aim of this work was to investigate its effect on ... -
Comparative study of improved vs. traditional apple cultivars and their aptitude to be minimally processed as "ready to eat" apple wedges
Altisent Rosell, Rosa; Plaza, Lucía; Alegre Vilas, Isabel; Viñas Almenar, Inmaculada; Abadias i Sero, Mª Isabel (Elsevier, 2014)The development of fresh-cut apple products requires the reconsideration of cultivar selection because different characteristics are required compared with those characteristics for the fresh market. The aim of this work ... -
