Antimicrobial packaging system for minimally processed fruit

Lara Lledó, Marta Inés (Universitat Politècnica de València, 2018-01-14)

[EN] In the present Doctoral Thesis, antimicrobial active packaging materials, at lab and at semi-industrial scale, have been developed with the aim to reduce the natural flora of peeled and cut fruit and extend its shelf ...
Antimicrobial properties and release of cinnamaldehyde in bilayer films based on polylactic acid (PLA) and starch

Muller, Justine; Casado Quesada, Alba; González Martínez, María Consuelo; Chiralt, A. (Elsevier, 2017)

[EN] Cinnamaldehyde (CIN) loaded amorphous PLA films were obtained by casting, using ethyl acetate as solvent. Likewise, bilayer films were obtained by thermocompression of the PLA active layer and compression moulded ...
Antioxidant poly (lactic acid) films with rice straw extract for food packaging applications

Vieira-De Freitas, Pedro Augusto; Bas Gil, Nuria Julia; González Martínez, María Consuelo; Chiralt, A. (Elsevier, 2022-12)

[EN] Antioxidant PLA films incorporating 2%, 4% and 6% of phenol-rich extract from rice straw (RS) were obtained by melt blending and compression-moulding. Aqueous RS extract was obtained by a combined ultrasound-reflux ...
Carvacrol encapsulation by electrospinning or solvent casting to obtain biodegradable multilayer active films for food packaging applications

Tampau, Alina (Universitat Politècnica de València, 2020-04-06)

[ES] El uso masivo de plásticos sintéticos y su impacto medioambiental obliga a buscar alternativas biodegradables para el envasado de los alimentos,etapa necesaria para su adecuada conservación.Así mismo,la necesidad de ...
Development and characterization of active films based on starch-PVA, containing silver nanoparticles

Cano Embuena, Amalia Isabel; Cháfer Nácher, María Teresa; Chiralt, A.; González Martínez, María Consuelo (Elsevier, 2016)

[EN] In order to obtain antimicrobial packaging films, starch-PVA-based films with silver nanoparticles (AgNPs) have been developed and characterized as to their physical and antimicrobial properties and silver release ...
Effect of ferulic and cinnamic acids on the functional and antimicrobial properties in thermo-processed PLA films

Ordóñez-Lagos, Ramón Alberto; Atarés Huerta, Lorena María; Chiralt A. (Elsevier, 2022-09-30)

[EN] The incorporation of ferulic or cinnamic acids as antimicrobial agents into PLA matrices to produce films with active properties for food packaging applications is evaluated in this study. The acids were incorporated ...
Encapsulation of eugenol by spray-drying using whey protein isolate or lecithin: Release kinetics, antioxidant and antimicrobial properties

Talón-Argente, Emmanuelle; Lampi, Anna-Maija; Vargas, Maria; Chiralt, A.; Jouppila, Kirsi; González Martínez, María Consuelo (Elsevier, 2019-10-15)

[EN] The encapsulation of eugenol (E) by spray-drying using whey protein (WP) or soy lecithin (LE) and maltodextrin in combination with oleic acid (OA) and chitosan (CH) was analysed in order to obtain antioxidant and ...
Films activos de PHBV con ácidos ferúlico y p-cumárico. Cinética de liberación y actividad antibacteriana

Navarro Palacios, Clara (Universitat Politècnica de València, 2022-10-19)

[ES] Los polímeros biodegradables para el envasado de alimentos se presentan como una alternativa sostenible para ayudar a minimizar el impacto medioambiental derivado de la producción y utilización excesiva de envases de ...
Propiedades antimicrobianas y liberación de cinamaldehido en films de PLA

Casado Quesada, Alba (Universitat Politècnica de València, 2016-10-13)

[ES] Propiedades antimicrobianas y liberación de cinamaldehído en films de PLA. Se han obtenido films de PLA con cinamaldehído como antimicrobiano por extensión y secado de sus disoluciones en acetato de etilo. También ...
Release and antibacterial action of phenolic acids incorporated into PHBV films

Moll-Montaner, Eva; González Martínez, María Consuelo; Chiralt, A. (Elsevier, 2023-09)

[EN] Ferulic or p-coumaric acids were incorporated (3, 6 or 9%) into PHBV films by melt processing or surface anchoring (3-4% in the film). The release kinetics of phenolics and the films' antibacterial effect against ...
Release kinetics and antimicrobial properties of carvacrol encapsulated in electrospun poly-(epsilon-caprolactone) nanofibres. Application in starch multilayer films

Tampau, Alina; González Martínez, María Consuelo; Chiralt, A. (Elsevier, 2018)

[EN] Electrospun poly-(epsilon-caprolactone) (PCL) fibre mats encapsulating Carvacrol (CA) were obtained with good encapsulation efficiency (85%) and CA load (11% in the fibre). These mats were effective at controlling the ...
