Abstract

Due to the substantial volume of waste produced and the potential for high-value bioactive compounds to be extracted from potato peel, the valorization of industrial waste of potato processing industry is the subject of this research. The study presents an innovative technique for efficient extraction of 4-hydroxybenzoic acid (P-HBA), a valuable bioactive molecule, from potato peel extract by utilizing molecularly imprinted chitosan beads (MICB). The MICB was synthesized using environmentally benign cross-linkers such as Tetraethyl orthosilicate (TEOS), Sodium triphosphate (STPP), while P-HBA was is used as a template. The MICB was investigated using FTIR, SEM, and EDAX. Adsorption studies were conducted to optimize parameters like adsorbent dose, solution concentration, time and pH. A recovery rate of 95.07 % is recorded from a synthetic P-HBA solution when measured by HPLC while from the actual potato processing industrial effluent the same is 40 %. The adsorption capacity of MICB is 67.5 mg g−1 and specific binding capacity is 20.62 mg g−1 which remained unchanged for six consecutive cycle reuse. This is the first study to report uptake of a bioactive molecule from actual potato processing industry waste.

从马铃薯加工工业废料中提取 4-羟基苯甲酸

由于马铃薯皮产生大量废弃物，且具有提取高价值生物活性化合物的潜力，因此马铃薯加工工业废弃物的价值化是本研究的主题。本研究提出了一种创新技术，利用分子印迹壳聚糖珠（MICB）从马铃薯皮提取物中高效提取有价值的生物活性分子--4-羟基苯甲酸（P-HBA）。分子印迹壳聚糖珠是利用对环境无害的交联剂（如正硅酸四乙酯（TEOS）和三聚磷酸钠（STPP））合成的，而 P-HBA 则被用作模板。使用傅立叶变换红外光谱（FTIR）、扫描电镜（SEM）和 EDAX 对 MICB 进行了研究。对吸附剂剂量、溶液浓度、时间和 pH 值等参数进行了优化。经 HPLC 测定，合成 P-HBA 溶液的回收率为 95.07%，而实际马铃薯加工工业废水的回收率为 40%。MICB 的吸附容量为 67.5 毫克/克-1，比结合容量为 20.62 毫克/克-1，在连续六个循环重复使用过程中保持不变。这是首次研究报告实际马铃薯加工业废水中生物活性分子的吸收情况。
