Subject(s): Online resources: Dissertation note: Tesis (Ingeniero Agroindustrial) -- UACh. Departamento de Ingeniería Agroindustrial, 2014 Abstract: El objetivo del presente estudio fue disenar capsulas conteniendo papaina a partir de una mezcla biopolimeros: carboximetilcelulosa:pectina (CMCPEC), pectina:carragenina (PECCAR), carboximetilcelulosa:alginato (CMCAGL) y alginato:carragenina (AGLCAR), con diferente capacidad de entrampamiento y liberacion bajo condiciones gastrointestinales simuladas. Las capsulas fueron elaboradas a partir de dispersiones de las mezclas de biopolimeros y papaina, mediante el metodo de extrusion sobre la disolucion de CaCl2. Se evaluo la eficiencia de encapsulacion de papaina y la cinetica de liberacion bajo exposicion a condiciones gastrointestinales simuladas. Los tratamientos de capsulas exhibieron diferencias en la eficiencia de entrampamiento, asi como en la especificidad de la liberacion en la exposicion a jugos gastricos y sales biliares simulados debido a la fuerza de interaccion entre biopolimeros y de estos con los iones calcio, que originan la formacion de matrices biopolimericas de diferente porosidad y liberacion de la papaina por difusion. Las capsulas de ALGCAR mostraron la mayor eficiencia para el encapsulado de la papaina y protegio la papaina de la degradacion. Los tratamientos mostraron distinto control de la entrega del bioactivo, las capsulas de PECCAR mostraron la mayor liberacion de papaina (p. 0.05) en jugos gastricos simulados (pH=3); capsulas de CMCALG exhibieron una entrega equivalente en jugos gastricos y en sales biliares simuladas; mientras que CMCPEC y ALGCAR, mostraron la mayor tasa de liberacion de papaina encapsulada tras la exposicion en sales biliares simuladas. Abstract: The main goal of this study was to design capsules which contains papain by a biopolymer mixture: carboxymethylcellulose: pectin ( CMCPEC ), pectin: carrageenan ( PECCAR ), carboxymethylcellulose: alginate ( CMCAGL ) and alginate: carrageenan ( AGLCAR ) with a different capacity of enclose and release under simulated gastrointestinal conditions. The capsules were prepared from dispersions of biopolymers mixtures and papain by using the method of extrusion on CaCl2 dissolution. The efficiency of papain encapsulation and kinetics release was evaluated under the exposure to simulated gastrointestinal conditions. The treatments of capsules developed differences in the enclosing efficiency and the specificity of release when exposed to simulated gastric juices and simulated bile salts, this because the strength of interaction between biopolymers and these with calcium ions, which cause the formation of biopolymer matrices of different porosity and papain release by diffusion. ALGCAR capsules showed the highest efficiency for papain encapsulation and also were protected from papain degradation. The treatments revealed different control at the delivering of bioactive, PECCAR capsules displayed the greatest release of papain ( p= 0.05) in simulated gastric juices (pH = 3); CMCALG capsules exhibited equivalent delivery in simulated gastric juices and simulated bile salts; while ALGCAR and CMCPEC capsules manifested the highest rate in releasing of encapsulated papain after exposing to simulated bile salts.
