“…A favourable effect on biodegradation was not found. Lignin seems to influence the kinetics of the overall degradation scenario but shows no overall positive impact [40]. Although lignin is generally regarded as very recalcitrant to biodegradation, the opposite is true for starch.…”

This chapter deals with the biodegradability of vinyl ester-based polymers with a special emphasis on poly(vinyl acetate) and poly(vinyl alcohol). A proper discussion of the importance of the biodegradability of a certain polymer class cannot be made without understanding the impact that polymer class has on the environment. Therefore, apart from discussing the actual biodegradation mechanisms, other issues will be addressed. These include, but are not limited to, how long the class of vinyl ester-based polymers has been known and produced on an industrial scale, what quantities are produced and released into the environment each year, and what applications are addressed with this polymer class. We will also look at the general physical and chemical properties of this polymer class and how these properties can influence biodegradability. After a discussion of what "biodegradability" actually means -and what not -the mechanisms for the biodegradation of poly(vinyl ester)s will be discussed in more detail and a summary given of the biological systems able to process poly(vinyl ester)s.

“…Lignin is a possible inducer for degradation if used in certain polymers, such as poly(vinyl alcohol) [59]. Further, natural phenols and socalled bio-inspired phenolic polymers, e.g., poly(caffeic acid methyl ester) (CAME) for polymer stabilization have been reported [60].…”

“…Thus, PVA degradation was improved by the starch incorporation in the matrix, surely due to easier permeation of the enzyme into the film matrix (Azhari et al, 2011;Julinová et al, 2010;Jayasekara et al, 2003).…”

“…It is likely that the different additives incorporated into the film will affect the degradation processes. In addition, although the biodegradation of both polymers has been reported by different authors (Avella et al, 2005;Du et al, 2008, Julinová et al, 2010Azahari et al, 2011;Chen et al, 1997;Jayasekara et al, 2003), scarce information has been found.…”

CONSIDERAN: que la memoria titulada "DIFFERENT STRATEGIES TO IMPROVE THE FUNCTIONALITY OF BIODEGRADABLE FILMS BASED ON STARCH ANDOTHER POLYMERS" que presenta Dª. Amalia Isabel Cano Embuena para aspirar al grado de Doctor por la Universitat Politècnica de València, reúne las condiciones adecuadas para constituir su tesis doctoral, por lo que AUTORIZAN a la interesada para su presentación. AgradecimientosA Amparo Chiralt por concederme la oportunidad de formar parte del grupo de "films". Ha sido un placer poder trabajar junto a un referente internacional en el ámbito de la investigación como tú. Gracias por tus aportes científicos y técnicos, por tu paciencia y dedicación, y por permitirme aprender y trabajar a tu lado.A Chelo González, tu apoyo durante estos cuatro años, la fuerza que me has transmitido para ir hacia delante, tus conocimientos científicos y las oportunidades que me has brindado para iniciarme en la investigación a nivel nacional e internacional son tan sólo algunas de las cosas que tengo que agradecerte. Gracias también por toda la confianza depositada en mí durante estos años y por el apoyo personal.A Maite Cháfer por haberme introducido en el área de la investigación dándome la oportunidad de conocer al grupo de "films". Tu apoyo profesional y personal y tu positividad frente a los problemas han sido de gran ayuda. A mis dos familias, sin vuestro apoyo esta Tesis no habría sido posible. En especial a Arturo, Mónica, José, Susana, Genaro, Merche y Arturo, nunca habéis puesto objeción a mis decisiones, apoyándome en todas y cada una de ellas. Gracias por la comprensión que habéis tenido conmigo cuando los nervios me han pasado alguna mala jugada.A mis pequeños, Diego, Josep, Rubén y Amalia, vuestra inocencia y alegría han sido dos cosas muy importantes para poder coger fuerzas para realizar un buen trabajo, os quiero.A mi madre, por empujarme siempre hacia los sueños, por hacerme creer que puedo y sobre todo por escucharme. Tus esfuerzos para aceptar todas las decisiones, respetar y compartir las idas y venidas que algún disgusto te han costado y acompañarme durante toda esta andadura han sido un pilar fundamental para mí.A Jorge, su confianza, su apoyo incondicional, sus ánimos, sus reflexiones y su participación activa en este gran proyecto desde que lo inicié, hoy dan su fruto. Sabes que muchas veces te he dicho que esta Tesis ha sido cosa de dos porque sin tu paciencia, sin el equilibrio y la estabilidad que me transmites y la felicidad que me aportas no hubiera llegado hasta el final. Gracias y mil gracias! AbstractIn the present Doctoral Thesis, different strategies to improve functional properties of starch films for food packaging applications were analysed: study of the effect of amylose:amylopectin ratio, blend with other polymers poly(vinyl alcohol) (PVA), and incorporation of different fillers (rice bran and cellulose nanocrystals-CNCs) and antimicrobial agents (neem oil-N, oregano essential oil-O and silver nanoparticlesAgNPs). Likewise, a biodegradation study of the films as affect...
