Antilisterial and physical properties of biopolymer films containing lactic acid bacteria

Sanchez-Gonzalez, L.; Quintero Saavedra, Jorge Ivan; Chiralt, A. (Elsevier, 2014-01)

Novel biopolymer films were developed and used to control Listeria innocua in an artificially contaminated synthetized medium. Two hydrocolloids, sodium caseinate (NaCas) and methylcellulose (MC), and two bacteriocin-producing ...
Effect of essential oils on properties of film forming emulsions and films based on HPMC and chitosan

Sánchez González, Laura; Chiralt, A.; González Martínez, María Consuelo; Cháfer Nácher, María Teresa (Elsevier, 2011)

[EN] Film-forming dispersions (FFD) and films, prepared by incorporating different concentrations of bergamot (BO), lemon (LO) and tea tree (TTO) essential oils into hydroxyproplymethylcellulose (HPMC) and chitosan (CH) ...
Effect of Homogenization Conditions on Physicochemical Properties of Chitosan-Based Film-Forming Dispersions and Films

Vargas, Maria; Perdones Montero, Ángela; Chiralt Boix, Mª Amparo; Cháfer Nácher, María Teresa; González Martínez, María Consuelo (Elsevier, 2011-07)

Film-forming dispersions (FFD) based on high molecular weight chitosan (CH) alone or in combination with oleic acid (OA) were prepared under different homogenization conditions (rotor-stator or rotor stator together with ...
Influence of homogenization conditions on physical properties and antioxidant activity of fully biodegradable pea protein-alpha-tocopherol films

Fabra, M. José; Jiménez, Alberto; Talens Oliag, Pau; Chiralt, A. (Springer Verlag (Germany), 2014-12)

In this study, antioxidant biodegradable films based on pea protein and alpha-tocopherol were successfully developed by solution casting. The effect of both the homogenization conditions (rotor stator and microfluidizer) ...
Physical and antimicrobial properties of starch-PVA blend films as affected by the incorporation of natural antimicrobial agents

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

[EN] In this work, active films based on starch and PVA (S:PVA ratio of 2:1) were developed by incorporating neem (NO) and oregano essential oils (OEO). First, a screening of the antifungal effectiveness of different ...
Physical and antioxidant properties of chitosan and methylcellulose based films containing resveratrol

Pastor Navarro, Clara; Sánchez González, Laura; Chiralt, A.; Cháfer Nácher, María Teresa; González Martínez, María Consuelo (Elsevier, 2013)

[EN] New trends in edible films focus on the improvement of their functionality through the incorporation of active compounds, such as antimicrobial or antioxidant agents. Resveratrol is a natural antioxidant found in a ...
Properties and ageing behaviour of pea starch films as affected by blend with poly(Vinyl Alcohol)

Cano Embuena, Amalia Isabel; Fortunati, Elena; Cháfer Nácher, María Teresa; Kenny, J.M.; Chiralt, A.; González Martínez, María Consuelo (Elsevier, 2015-06)

[EN] Pea starch (S) and poly(vinyl alcohol) (PVA) blends with different ratios were produced in order to elucidate the possible advantages of blend films to overcome the common drawbacks of starch films. Starch, poly(vinyl ...
Use of tannins to enhance the functional properties of protein based films.

Cano, A.; Andrés, M.; Chiralt Boix, Mª Amparo; González Martínez, María Consuelo (Elsevier, 2020-03)

[EN] In this study, three tannins from different sources have been used (from white peel grape (W), red peel grape (R) and from oak bark (O)) to obtain active films based on proteins (caseinate and gelatin) on the basis ...
Water interactions and microstructure of chitosan-methylcellulose composite films as affected by ionic concentration

Vargas, Maria; Albors, A.; Chiralt, A.; González Martínez, María Consuelo (Elsevier, 2011)

[EN] Edible films based on high molecular weight chitosan (CH) and methylcellulose (MC) were obtained by mixing different ratios (0:1, 0.5:1.5, 1.0:1.0, 1.5:0.5 and 1:0) of the biopolymers in two solvent conditions (0.95 ...
