Synthesis Of Carboxymethyl Polysaccharides From Palm Seed Powder (arenga Pinnata Merr.) And Sodium Chloroasetate By Heating On The Microwave
Introduction
The synthesis of carboxymethyl polysaccharides from palm seeds (Arenga pinnata Merr.) has gained significant attention in recent years due to its potential applications in various industries, including food, pharmaceuticals, and biomedicine. The process involves the extraction of polysaccharides from palm seeds, followed by an eternalification reaction with sodium chloroacetate to produce carboxymethyl polysaccharides. In this study, we employed a novel approach using microwave heating to enhance the efficiency and reduce the processing time of the synthesis process.
Materials and Methods
The palm seeds (Arenga pinnata Merr.) were obtained from a local market and dried to a constant weight. The polysaccharides were extracted from the dried palm seeds using a solvent mixture of ethanol and water. The extracted polysaccharide powder was then analyzed using Fourier Transform Infrared Spectroscopy (FT-IR), X-Ray Diffraction (XRD), and Scanning Electron Microscopy (SEM) to understand its structure and characteristics.
The eternalification reaction was carried out using sodium chloroacetate (SCA) and sodium hydroxide (NaOH) as catalysts. The weight ratio of SCA to NaOH was varied to investigate its effect on the synthesis process. The reaction mixture was then heated using a microwave oven at a power of 10W for 3 minutes.
Results and Discussion
The formation of carboxymethyl polysaccharides was confirmed by the emergence of absorption bands in the area of ​​the wave number 1729 cm-1, indicating the vibration of stretching C = O of the carboxymethyl group. The degree of substitution produced through the titration method ranged from 0.1007 to 0.4179, signifying the success rate of eternalization reactions.
Analysis using XRD showed that the intensity of carboxymethyl polysaccharides from palm seeds was lower compared to pure palm seed polysaccharides, indicating a change in the crystal structure of the polysaccharide. SEM analysis revealed changes in surface morphology, where fine fibers that initially appeared irregular turned into rough fibers with the appearance of small cavities.
Analysis and Importance of this Research
The synthesis of carboxymethyl polysaccharides from palm seeds has significant potential in various applications, especially in the food, pharmaceutical, and biomedical industries. Carboxymethyl polysaccharides are known to have gel properties, thermal stability, and the ability to form films, making it a very useful material in the development of products that require endurance and stability.
The heating process using a microwave in this synthesis is also an innovative step that can increase reaction efficiency, reduce processing time, and reduce energy use. In addition, the use of natural raw materials such as palm seeds is in line with the principle of sustainability, considering that palm seeds are agricultural waste that can be utilized.
Success in the synthesis of carboxymethyl polysaccharides opens opportunities for further research on other structural modifications that can improve the functional nature of the polysaccharide. By understanding and exploring the new properties resulting from this modification, it is hoped that new applications can be found that can expand the use of carboxymethyl polysaccharides in modern industries.
