ZARITSKY, N., AutorEdible coatings can extend the shelf-life of foods by functioning as solute, gas, and water vapor barriers. Moreover, they can be used as a host for additives in the conservation of the properties of the product or simply in order to improve its[...]texto impreso
The aqueous extract of two ecotypes of murta (Ugni molinae Turcz) leaves (Soloyo Grande ‘‘SG’’ and Soloyo Chico ‘‘SC’’), were analysed for their antioxidant capacity, SC extract exhibiting a higher antioxidant capacity than SG extract. This diff[...]texto impreso
Antimicrobial films appear in response of the searching for more competitive and aggregated value packaging. With the aim of developing packages that, besides active are also biodegradable, this work proposes to study the effect of antimicrobial[...]texto impreso
Proteins from fish muscle are biopolymers capable of forming edible films. Thus, the objective of this paper was the study of some physical properties of films produced with the sarcoplasmic and myofibrillar proteins (MP) from Thai Tilapia muscl[...]texto impreso
Moisture sorption isotherms and water barrier properties of films made from hydroxypropyl methylcellulose (HPMC) containing surfactant mixtures of sorbitan monostearate (SPAN 60) and sucrose palmitate (sucrose ester P-1570) were evaluated at 10 [...]texto impreso
Myofibrillar and sarcoplasmic proteins are capable of forming a continuous matrix. Therefore,muscle proteins of two varieties of Tilapia were used to study the effect of the thermal treatment of filmogenic solutions (FS) on the mechanical proper[...]texto impreso
Biofilms are made of biopolymers. In the casting technique, biofilms are obtained by the drying of a polymer suspension in the final stage of processing. The aim of the present paper was to analyze the effect of this drying process on the mechan[...]texto impreso
The objective of this paper was to study the effect of plasticizers and their concentrations on the thermal and functional properties of gelatin-based films. Four polyols (glycerol—GLY, propylene glycol—PPG, di- DTG and ethylene glycol—ETG) were[...]Article : documento electrónico
ESCOBAR, DANIELA, Autor ; MÁRQUEZ, ROSA, Autor ; SILVERA, CARLOS, Autor ; SALA, ANGELINA, Autor ; REPISO, LUIS, Autor |Dentro INNOTEC (No. 3, dic. 2008)El incremento del interés en alimentos de alta calidad con mayor vida útil y un menor impacto a nivel ambiental ha llevado al estudio y desarrollo de películas y coberturas comestibles y/o biodegradables. Éstas son una excelente alternativa de e[...]texto impreso
En los últimos años se ha investigado intensamente en el campo de los films y recubrimientos comestibles y los esfuerzos continúan debido a la creciente demanda por parte de los consumidores respecto de alimentos de calidad, saludables y seguros[...]Article : documento electrónico
KADAFFI LEÓN ARCE ORTIZ, Autor ; KAREN JOHANA ORTEGA VILLALBA, Autor ; CLAUDIA ISABEL OCHOA-MARTINEZ, Autor ; CARLOS VÉLEZ PASOS, Autor |Los recubrimientos y películas elaborados lactosuero (WPI) y quitosano (CHI) son conocidos por ser antifúngicos y por ser barrera para la transferencia de vapor de agua, logrando un efecto en la conservación de frutas. El objetivo de este trabaj[...]texto impreso
The use of meat myofibrillar proteins for edible film production involves initially the extraction of the macromolecule, since it is not commercially available. Thus, the objectives of this work were the extraction and characterization of bovine[...]texto impreso
ANDERSON, AARON S. ; DATTELBAUM, ANDREW M. ; MONTAÑO, GABRIEL A. ; PRICE, DOMINIQUE N. ; SCHMIDT, JURGEN G. ; MARTINEZ, JENNIFER S. ; GRACE, W. KEVIN ; GRACE, KAREN M. ; SWANSON, BASIL I.We report a general procedure to prepare functional organic thin films for biological assays on oxide surfaces. Silica surfaces were functionalized by self-assembly of an amine-terminated silane film using both vapor- and solution-phase depositi[...]texto impreso
Biodegradable films from many protein sources have in recent decades attracted a lot of attention for their potential use in food protection because they have several advantages over synthetic films, including those related to the environment. T[...]texto impreso
The influence of glycerol concentration on some physical properties such as the thermal, mechanical, water solubility, hydrophilicity and water barrier properties of feather keratin films was studied. Feather keratin was extracted with an aqueou[...]
