answer:# Results and Discussion Quantitative Analysis of Pectin from Mango Peel The quantification of mango peel pectin components was performed through High-Performance Liquid Chromatography (HPLC), revealing the composition of the main structural polysaccharides. The analysis focused on determining the galacturonic acid content, which is a critical indicator of pectin quality and usability in various industrial applications. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) stipulates that pectin must have a galacturonic acid content greater than 65% to be considered of acceptable quality for food applications. However, our findings showed a galacturonic acid content of 37.2%, falling significantly short of this requirement. This result indicates that the pectin extracted from mango peel in our study may not meet the standards for food additive uses without further purification or modification processes. Besides galacturonic acid, the presence of other polysaccharides was noted, with cellulose being the second most abundant component at 23.5%. This is noteworthy, as cellulose is not a desired component in pectin preparations, primarily because it does not contribute to the gelling properties characteristic of high-quality pectin. Additionally, a combined presence of xylose, fructose, mannose, and rhamnose constituted 11.2% of the pectin composition. These sugars relate to the structural diversity of pectin and may influence its functionality in applications requiring specific textural or gelling properties. Arabinose content was measured at 16.8%, indicating a substantial presence of arabinans, which are known to impact the solubility and gelling dynamics of pectin. The presence of levoglucosan at 7.1% further suggests the degradation of polysaccharides, likely due to the extraction process, which could affect the overall quality and usability of the pectin. The remaining 4.2% of the composition was classified as "others," encompassing minor components that were not specifically identified in this analysis. These could include phenolics, proteins, and minerals that may influence the color, stability, or gelling properties of pectin. Implications of the Findings The significant discrepancy between the galacturonic acid content found in our mango peel pectin and the JECFA standards raises questions about the direct applicability of this pectin in food industries without further refinement. The presence of substantial amounts of non-pectic polysaccharides and degradation products such as levoglucosan suggests that the extraction method needs optimization to increase the purity and yield of galacturonic acid. Future studies should focus on refining the extraction process, possibly through the implementation of enzymatic treatments or selective precipitation techniques, to enhance the quality of mango peel pectin. Furthermore, exploring the potential of this pectin in non-food applications where the strict requirements for galacturonic acid content may not apply could be a valuable avenue of research. Given the renewable nature of mango peel waste, optimizing the value extraction from this resource remains a critical goal for sustainability in agro-industrial practices. In conclusion, while the pectin extracted from mango peel does not meet the current JECFA standards for food-grade pectin, its composition suggests potential uses in other industries or applications. Further research into the optimization of extraction methods could pave the way for more sustainable and economically viable uses of agricultural by-products such as mango peel.
