AB The increasing interest of pectin derived compounds as functional additives in thepharmaceutical and food industries demands new sources and eco-friendlyextraction approaches. In this regard, onion peel wastes (OPW) hold great potential,with over 450,000 tons of OPW being discarded annually [1], despite theirremarkable pectin content. Pectins are commonly extracted acid hydrolysis (pH 2,>85 °C), that yield mainly the HG domain, due to complete hydrolysis of thebranched domains or enzymatic hydrolysis, which is time consuming, but yieldsbranched pectin rich in RG-I and RG-II domains. As an alternative to theconventional process for producing pectin derived compounds (PDC),hydrothermal hydrolysis based on subcritical water (SubW) is emerging as an eco-friendly technique. SubW refers to water at temperatures ranging from 100 °C(boiling temperature) to 374 °C (critical temperature), which remains in a liquid statedue to the application of pressure. SubW can facilitate the extraction of pectin fromnatural matrices, and by controlling the operational parameters, pectin can betailored into smaller units with varying degrees of polymerization to produce PDC.However, in practice, accurate control of experimental conditions has emerged asthe primary challenge of the SubW extraction process, which can lead to theformation of undesired degradation products, and uncontrolled molecular weightreduction of the pectin.
