دراسة بعض الخصائص الفيزيوكيميائية للبكتين المستخلص من قشور البرتقال (Citrus sinensis).

Abstract

In this study, Pectin was extracted from orange peels (Citrus sinensis), using the method (Lira-Ortiz et al., 2014) using citric acid. some of its physiochemical properties were studied, including (extraction yield, total ash content, equivalent weight, and methoxyl content). This study was conducted at the University of Latakia, Faculty of Agricultural Engineering, Department of Food Sciences /2025. The results indicated that the extraction yield of pectin from dried orange peels was within the acceptable range reported in scientific studies for citrus pectin extraction, reaching 16.5%. The total ash content test of the extracted pectin sample showed a value of 4.15%, which indicates a high level of purity and low content of inorganic impurities and excess minerals. The calculated equivalent weight, which reached 500 mg/meq, also pointed to the high quality of the extracted pectin, enhancing its potential for industrial applications. Furthermore, the obtained methoxyl content value (4.96%) reflected the superior quality of the pectin extracted from orange peels, confirming the effectiveness of using citric acid as an environmentally friendly and safe option for extracting high-quality pectin from natural sources.
