“…After pectin is fully separated, it can be dried at low temperatures that guarantee the thermal stability of the polymer. It is possible to used use vacuum drying at 40°C for short periods of time (1-2 h) [1,11,16,19] or convection drying at 50-55°C for 16 to 24 h [8,9,12,15,17,18,22,23,25]. It is important to highlight that pectin yields are primarily affected by other process stages, not by the drying step.…”

“…In another work, Budarin et al proposed the use of microwave-assisted steam distillation (using only the water present in the peel) and microwave-assisted hydrothermal treatment to obtain essential oils, pectin but also hydroxymethylfurfural and 5-chloromethyl furfural (CMF) which can be used as platform chemicals to produce herbicides, insecticides, pharmaceuticals, monomers, solvents and fuels [31]. Ortiz-Sanchez et al proposed the anaerobic digestion of the solid residue obtained after acid hydrolysis to produce biogas with a high methane content [9], and also the use of hydrolyzed pectin in a fermentation process with fungi (T. r e e s e i ) to produce mucic acid [23]. Hydrolysates from orange peel have also been evaluated for their potential to produce other organic acids, such as succinic acid, with the help of fermenting bacteria [15,32].…”

This chapter describes the pectin production process from citrus residues. It discusses the importance of essential oils removal before processing through steam distillation, hydrodistillation, or solvent extraction. Also, it presents different extraction methods (acid hydrolysis, microwave-assisted acid hydrolysis, and hydrodistillation) that have been employed and different solvents that can be used for its purification. Since all these processing parameters can affect the final pectin yield and quality, a discussion is made on which processing options and conditions could be used based on recently reported data. The best operational conditions based on the percentages of pectin recovery and their relationship with quality parameters, such as the galacturonic acid content and degree of esterification are presented. Finally, a discussion is made regarding the opportunities for its integration under the biorefinery concept that could help to enhance several economic and environmental aspects of the process.

“…It is due to the transformation of mechanical properties (and elastic-brittle) of pectin, and modification of polymer chain (demethoxylation and decarboxylation of pectin, process of water volatilization) took place in T g temperature of both pectin [56]. While increasing temperature directs to move the polymer chains liberally at T m it leads to degrade the structure of polymer [52,57]. In commercial pectin, arrangements of polymers in an orderly manner that make them crystals at Tc of 188.5 °C and the presence of some proteins could lead to establishing the additional endothermic peak [58].…”

The intention of this present study is to optimize the recovery of pectin from Persea americana peel (PAP) examining four independent process variables (pH, solvent to substrate ratio (SSR) (ml/g), agitation time (AGT) (h), and agitation speed (AGS) (rpm)) and compare the pectin recovery (PR) using statistical (Box-Behnken response surface design (BBRESD)) and non-statistical (artificial neural network (ANN) with genetic algorithm (GA)) methods. Optimal condition derived in ANN-GA (pH of 1.9, SSR of 16 ml/g, AGT of 2.1 h, AGS of 99 rpm, and PR of 90.59%) has forecast PR very precisely than BBRESD (pH of 2, SSR of 14 ml/g, AGT of 2 h, AGS of 100 rpm, and PR of 85.44%). Extrapolative capacities of two methods were examined by several statistical restraints. Structural analysis (FT-IR and XRD) of PR was exhibited that highly esterified and amorphous nature of pectin was recovered from PAP. Recovered pectin was melted at the temperature of 258.5 °C which was similar to commercial pectin. SEM observations revealed that recovered pectin was flake and spherical particle. The results of this work suggested that pectin from PAP is one of the good sources to recover pectin with good quality as commercial pectin and used as a food ingredient.

“…En cuanto a la viabilidad económica de estos procesos, se han reportado análisis económicos para biorrefinerías con capacidad de tratamiento integral de hasta 100.000 toneladas de cáscara de naranja al año mediante procesos biotecnológicos, obteniendo como principales productos limoneno, pectina, etanol y metano, este último usado como fuente de energía en diversas etapas del mismo proceso de biorrefinería [11]. No obstante, algunos autores afirman que los altos costos asociados a etapas específicas de producción en una biorrefinería de naranja dificultan la posibilidad de implementar algunos procesos específicos [13].…”

Contexto: Se estudió la valoración integral de cáscara de naranja bajo un esquema de biorrefinería en el que se obtiene aceite de naranja (con hidrolato como subproducto y la valorización del aceite mediante la extracción de limoneno en etapas posteriores), pectina y harina para uso como suplemento en alimentación animal. Método: El proceso consistió en cuatro etapas generales: i) extracción y obtención de aceite e hidrolato de naranja mediante el proceso de arrastre de vapor, ii) obtención de limoneno, iii) extracción de pectina por medio de hidrolisis ácida, y iv) obtención de pienso a partir de procesos de centrifugado y secado. Resultados: Los experimentos y las caracterizaciones se realizaron a escala laboratorio, donde a partir de 700 g de cáscara (húmeda) se obtuvieron 3,34 mL de aceite (80-85 % limoneno), alrededor de 500 mL de hidrolato y cerca de 260 g de residuos sólidos (secos). De estos últimos, a partir de lotes de 50 g de material seco, se obtuvieron 9,7 g de pectina y alrededor de 40,3 g de harina para suplemento en alimentación animal. Conclusiones: Según el análisis técnico-económico para la escala de producción utilizada y para el contexto nacional, se logran indicadores positivos como el valor presente neto (27’271.933) y la tasa interna de retorno (5,27 %), que muestran la alternativa de inversión interesante como para ser considerada una opción de valoración de residuos por pequeños y medianos productores de cítricos en el país.
