Investigation of combined effects of independent variables on extraction of pectin from banana peel using response surface methodology

Extracción Rápida de Pectina a Partir de Cáscara de Maracuyá (Passiflora edulis flavicarpa) empleando Microondas

“…Esta capacidad depende de la molécula péctica y de su grado de metoxilación (Badui, 2013). Para la extracción de pectinas se han empleados diversas técnicas: las convencionales como la extracción por arrastre de vapor e hidrodestilación, las no convencionales como la extracción asistida por microondas (EAM) y la extracción por hidrólisis ácida que es aplicada ampliamente a nivel industrial (Qiu et al, 2010). La extracción asistida por microondas es un método recientemente utilizado con el propósito de liberar la pectina a partir de diversas materias primas y con su utilización se han encontrado resultados bastante deseables en el proceso de extracción de la pectina como la reducción de los tiempos de extracción, altos rendimientos en pectina y buena calidad del producto obtenido (López et al, 2011).…”

A Review: Different Extraction Techniques of Pectin

“…Different enzymes such as polygalacturonase, hemicellulose, protease and microbial mixed enzymes, cellulose, α-amylase, celluclast, alcalase and α-amylase and neutrase, Xylase, cellulose, b-glucosidase, endopolygalacturonase and pectinesterase are used in pectin extraction as enzymes have the ability to degrade pectin and modify the physicochemical properties of the pectin [74][75][76][77][78][79][80][81][82].…”

Influence of different treatment condition on biopolymer yield production for coagulation-flocculation process

“…376.82 23 This indicated that the biopolymer was difficult to be extracted from the plant cell wall when the condition was too minimal in temperature and time. According to other study, degradation of biopolymer chain molecules occurred during longer extraction time and the higher extraction temperature which affected biopolymer extraction rate [12]. It was found that pH 1.5 with constant temperature and time can produce higher yield compared to pH 2.…”

“…As for individual effects, temperature and time were the most influential factors at pvalue 0.0246 and 0.0001 respectively. It is believed that by increasing the temperature in a harsh condition, it could increase the extraction rate of the extracted biopolymer [12]. In addition, favourable acidic conditions contribute to increase of biopolymer recovery by hydrolysing the insoluble biopolymer constituents into soluble biopolymer.…”

“…However, only three of the parameters seem to influence considerably on the quantity of pectin; which is pH, temperature and extracted time [14]. The extraction rate of biopolymer increases at higher temperature of the extraction process [12]. While previous study discovered that pH and time is the most significant parameter on the biopolymer yield [13].Biopolymer known as pectin, has an important functional group to react as bioflocculating agent, which is efficient in wastewater treatment process.…”
