“…As depicted in Figure 4, the obtained FTIR for the commercial pectin and citrus pectin showed similar characteristics, especially in the region between 1600-1630 cm −1 and 1740-1760 cm −1 , which corresponds to the free and esterified carboxyl groups [29,30]. Additionally, bands originating from the stretching vibration of the methyl (CH3) group in the methyl ester around 2800-3000 cm −1 correspond to C-H absorption [31]. The stretching of hydroxyl (O-H) groups was responsible for the wider band ranging from 2400 to 3600 cm −1 due to moisture present in both the commercial pectin and citrus pectin samples [29,32].…”

This paper presents the development of an environmentally friendly, small molecular depressant citrus pectin for improving the recovery of cassiterite resources. Citrus pectin extracted from citrus peel was utilized as the depressant, and it demonstrated significant potential in separating calcite from cassiterite in micro-flotation tests. The molecular weight of the citrus pectin extracted in this paper decreased from 11,485,412 Da to 32,959 Da compared to commercial pectin, resulting in the depressant efficiency of the reagent. The results of a zeta potential and adsorption test indicated that citrus pectin had less and weaker adsorption on the cassiterite surface and could be replaced with NaOL. The chemical adsorption process of citrus pectin on the surface of calcite was determined through FTIR spectroscopy analysis. XPS analysis results indicated that the interaction between the carboxyl groups of citrus pectin and calcium atoms enables adsorption to occur. The AFM revealed that citrus pectin displayed a uniform and dense pattern of point-like adsorption on the surface of calcite. Micro-flotation experiments showed that cassiterite recovery of 80% can be obtained at a citrus pectin dosage of 10 mg/L. Citrus pectin has the advantages of being low-cost, highly selective, and environmentally suitable, making it a promising alternative to conventional reagents.

“…Berdasarkan acuan IPPA, kadar metoksil pektin yang didapatkan setelah ekstraksi selama 5 dan 15 menit termasuk ke dalam kategori metoksil sedang, sedangkan kadar metoksil pektin yang diperoleh setelah ekstraksi selama 10 menit termasuk ke dalam kadar metoksil tinggi. Kadar metoksil pektin dari kulit pisang ambon juga lebih tinggi daripada pektin yang diekstraksi dari kulit pisang kepok, yaitu 3,60%, sebagaimana dilaporkan oleh Pagarra et al (2020).…”

Limbah kulit buah pisang ambon hijau (Musa acuminata Colla) merupakan salah satu kandidat bahan baku pektin yang murah dan mudah ditemukan. Ekstraksi pektin dapat dilakukan dengan berbagai metode dan pelarut asam, namun akan mempengaruhi rendemen serta karakteristik pektin yang dihasilkan. Di sisi lain, spektroskopi FTIR dapat digunakan untuk karakterisasi pektin secara cepat, mudah, dengan sejumlah kecil sampel, tetapi data spektrum vibrasi pada rentang bilangan gelombang yang cukup luas seringkali tidak mudah dibedakan antar sampel. Analisis kemometrik multivariat dapat diterapkan untuk memudahkan analisis data. Tujuan penelitian ini adalah untuk membandingkan karakteristik pektin yang diekstraksi dari kulit pisang dengan variasi pelarut (asam klorida dan asam sitrat) dan waktu ekstraksi (5, 10, dan 15 menit) menggunakan metode microwave, serta melakukan komparasi pektin hasil ekstraksi terhadap pektin komersial dengan metode analisis FTIR dan kemometrik. Hasil penelitian menunjukkan keberhasilan ekstraksi pektin yang dikonfirmasi dengan adanya vibrasi gugus fungsi pektin pada spektrum FTIR. Analisis semi-kuantitatif dengan perbandingan data serapan gugus karboksil teresterifikasi dan karboksil bebas menunjukkan pektin hasil ekstraksi dengan pelarut asam sitrat memiliki derajat esterifikasi lebih tinggi dibandingkan hasil ekstraksi dengan asam klorida. Analisis komponen utama mengonfirmasi kedekatan spektrum pektin hasil ekstraksi dengan asam sitrat ataupun asam klorida selama 10 menit dengan spektrum pektin komersial.Characterization of Pectin Extracted from Banana Peels (Musa acuminata Colla) using FTIR Spectroscopy and Chemometric Analysis. The peel of green banana Musa acuminata Colla is a potential source of pectin. Pectin extraction can be performed using various methods and solvents, but it might influence the characteristics of the result. On the other hand, FTIR spectroscopy can be used to rapidly and simply characterize pectin, but the vibrational data over a wide range of wavenumbers is not easily distinguished between samples. Multivariate chemometric analysis can be applied to ease data analysis. This study aimed to compare the characteristics of pectin obtained after microwave-assisted extraction of the banana peels using different solvents (hydrochloric acid and citric acid) and extraction time (5, 10, and 15 minutes), as well as to compare those pectins toward its commercial grade using chemometric analysis. The result showed successful pectin extraction, as revealed by particular vibrations of functional groups in the pectin structure. Based on semi-quantitative analysis, the absorption band ratio between esterified carboxyl groups and free carboxyl groups revealed that the pectin extracted using citric acid had a higher degree of esterification than that extracted using hydrochloric acid. Principal component analysis confirmed the closeness of pectin obtained after 10 minutes of extraction using citric acid or hydrochloric acid to that of commercial pectin.

The increasing use of conventional plastic has been creating some big problems, ranging from the oil crisis as a raw material for plastic production and the accumulation of unbiodegradable plastic waste on the earth. One of the promising measures to handle the problem is the use of environmentally–friendly biodegradable plastic, made from renewable materials. The aim of this project is to characterize the properties of bio-plastic from banana peel. The process begins with the extraction of pectin from banana peel with hydrochloric acid and followed by the addition of water, CaSO4, tapioca starch, acetic acid, glycerin to form plastic. The analysis of pectin extract gave 8.3 % pectin yield, 29 % water content, 10 % ash content, 4.9 % metoxyl content, 50 % galacturonic acid content,and 13.8 % degree of esterification. The plastic obtained after the following process had the thickness of 0.28 mm, the water absorption capability of 53.8 %, and it was biodegradable with certain characteristics.
