Exploring techno-functional properties, synergies, and challenges of pectins: A review

In this review, various aspects of pectins (from raw materials to process-structure-function-applications of this multifunctional biomacromolecule) are discussed taking into consideration the interests of scientists, producers, formulators, including customers and market constraints. Research on pectins has been a subject of interest among many researchers, consequently, numerous articles were published in the past decade. However, there are still some controversial ideas and related challenges associated with this multifunctional polymer which need further clarification. To settle on each of them, the review is structured into four parts: (i) what is already known, (ii) mechanisms describing the physicochemical phenomena involved in pectin techno-functional properties, (iii) current and future challenges from multiple angles, and (iv) related market trends. The information disclosed in this review could be particularly useful for pectin producers allowing them to boost sustainable innovation and also for those seeking in-depth knowledge on different aspects of this versatile biopolymer. Additionally, this review will provide the reader with the tools which allow obtaining fundamental and applied knowledge on pectins.
