“…It could be observed that peak at 3388.9 cm -1 due to O-H stretching that comes from O-H functional groups in carbohydrates and moisture. The presence of moisture is confirmed by the existence of peak at 1643.35 cm -1 (Tarigan et al 2020). The peaks around 2800-3000 cm -1 indicate C-H stretching, while peaks around 1000-1200 cm -1 indicate the presence of C-O-C and C-O functional groups (Mittal et al 2016).…”

Over the last few years, there is a significant growth in research exploring natural based coagulant due to its various benefits to decrease or even substitute the usage of inorganic chemical coagulants. Polysaccharide based coagulant and coagulant aid is a promising source for this purpose, due to its abundance. In this study, we reported utilization of galactomannan extracted from spent coffee grounds as natural coagulant aid in coagulation of Congo red synthetic wastewater. The coagulation was done at fixed dosage of FeCl3 (160 mg/L) and pH of 6. The effect of galactomannan as coagulant aid was observed by varying galactomannan dosage (0-140 mg/L) and Congo red concentration (20–70 mg/L). It was found that galactomannan as coagulant aid could increase the removal of Congo red, around 30–90% removal, depends on Congo red concentration, compared FeCl3 only (0–65%). The coagulation adsorption study was also investigated using Langmuir, Freundlich, and Brunauer – Emmet – Teller (BET) isotherm models. It was found that Congo red coagulation using FeCl3 only was following Langmuir isotherm, indicating monolayer – homogenous formation during the coagulation. On the other hand, with the presence of galactomannan the coagulation was best described by BET isotherm, indicating multilayer – heterogeneous adsorption, possibly due to interparticle bridging of galactomannan during colloid aggregation. The findings in this study suggest synergistic effect of galactomannan and FeCl3 in the coagulation process and proved potential of galactomannan from spent coffee grounds as natural coagulant aid.

“…In India, the Muthuvan tribal community of the Idukki district in Kerala utilizes the stem for the extraction of starch and used for various dishes and directly consumes it without fermentation (Asha & Pushpangadan, 2002). Immature A. pinnata endosperm is abundant in polysaccharides which are mainly composed of galactomannan (Tarigan et al, 2020). The apical bud of A. obtusifolia is known as a 'palm heart', which is eaten as a vegetable (Haynes & McLaughlin, 2000).…”

The genus Arenga belongs to the Arecaceae family, which has a significant economic value. Several species of this genus have a decent potential of becoming an industrial crop. In India, four species of the genus, namely Arenga pinnata, A. obtusifolia, A. micranta, and A. wightii have been reported. These species have not been cultivated on a commercial scale in most of the growing regions. People use this plant directly from the forest or those produced in their backyard, even though productivity is minimal. To date, several studies from throughout the world have reported numerous beneficial roles of such species. Proper use of such plants or their products has immense significance in the food, fiber, and pharmaceutical industry. These plants are also recognized as ecologically significant plants. In this article, we have presented an up‐to‐date review on the species of Arenga reported from India along with their potential utility as industrial crops. This review is motivated by the desire to produce many eco‐friendly resources from A. pinnata and other species of Arenga, which can contribute to an increase in the standard of living and economy of many nations, including India. Practical applications Arenga has a lot of potential as medicinal as well as industrial raw materials. Despite this, these plants are somehow underutilized and have not gained much attention in international trade. In this communication, we have presented some aspects of these plants by reviewing many research articles and conference proceedings. The utilization of these plants as traditional medicine serves an important part in basic health care for many people in developing nations. Gradual study and clinical trial of different formulations of these plants can explore novel drugs for some critical disorders. We also highlighted the industrial uses of these species. Biofuel and fiber obtained from A. pinnata have been appreciated by the researchers. This article points out some attributes of these plants that required further improvement. Botanists and phytochemists will appreciate the description of the medicinal properties of these plants and the biological data provided in the article.

“…Water dissolved and undissolved fibre has antioxidant activity [17]. Major polysaccharide in APE is galactomannan which is water dissolved polysaccharide [18] with ratio galactose: mannose of 1: 1.33 and has IC50 value of 22.109 mg/ml [16]. Galactomannan contains branched-chain of galactose, which is polar and mannose, which is non-polar.…”

Mesoporous Aerogel of Arenga Pinnata Endosperm and Their Application to Adsorb Vitamin E From Palm Fatty Acid Distillate

et al. 2020

Objective: The mesoporous aerogel (MA) has been produced from Arenga pinnata endosperm (APE) and was used to adsorb vitamin E from palm fatty acid distillate (PFAD). Methods: The adsorption process was carried out through the alcogel stage, followed by drying under dry air and reduced pressure. In the present work response surface methodology based on Box-Benhken design experiment was used to investigate the effect of dry APE types (1–3), the concentration of APE (1–1.5%, wt./v) and solvent exchange time (12–36 h). Results: Based on the result, the optimum parameter to produce aerogel with low-density value are as follows: APE type of 1 with a concentration of 1.5% (wt./v) and 48 h solvent exchange time. The MA occurred from this parameters has diameter of 3.142–3.212 nm. The surface morphology of MA had changed from roughly hollowed to smooth and the amorf intensity decreased after vitamin E adsorption process. Conclusion: The APE aerogels could adsorb vitamin E because the pores of aerogels and the galactomannan as the main component contains the branches galactose, which have hydrophilic phase and mannose which have hydrophobic phase, therefore, hydrophobic vitamin E are easy adsorbed on aerogels.
