As a greener alternative, Pectic Polysaccharides (pectin) can act as a kinetic hydrate inhibitor (KHI) to delay hydrate formation. We evaluated the performance of amidated pectin (AMP), a type of pectin with higher electronegative functional groups, using a high-pressure micro-differential scanning calorimeter (HP µ-DSC) under isobaric conditions with constant cooling. We compared AMP to low-methoxylated pectin (LMP) and high-methoxylated pectin (HMP) and found that AMP was the best KHI among the tested pectin types. At a concentration of 1.0 wt., the AMP Relative Inhibitor Performance (RIP) was 0.10, and at 0.1 wt., it had an RIP of 0.07, which were the only positive RIPs obtained amongst the tested KHIs. The results suggest that AMP can be a sustainable KHI option in extremely cold environments where the KHI effectiveness typically declines. © 2023 by the authors. date: 2023 official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85159269246&doi=10.3390%2fpolym15092080&partnerID=40&md5=8cebb5c62d9b7bf06d4de1ac536d0d56 id_number: 10.3390/polym15092080 full_text_status: none publication: Polymers volume: 15 number: 9 refereed: TRUE citation: Effendi, A.D. and Md Yusof, M.A. and Abd Mutalib, N.F. and Sia, C.W.
