The current study was focused on new approaches for debittering of by-products like kinnow pomace and kinnow pulp residue by using various food grade mild chemical methods, such as alkali treatment, acid treatment, and solventogenesis. Whereas in the studied various chemical treatments, the solventogenesis method with acetone resulted in maximum extraction of naringin and limonene from kinnow pomace and pulp residue and showed high acceptability for food product development. The acetone treatment was further optimized by RSM for the maximum extraction of naringin and limonene. Under optimized conditions, the maximum amount of naringin and limonene extracted were found to be 8.955, 2.122 mg/g from kinnow pomace and 9.971, 3.838 mg/g from pulp residue, respectively. This process can not only result in the effective utilization of agro-industrial by-product but also provide a sustainable solution to the environmental pollution caused by kinnow juice industry.
本研究旨在探索新的方法，通过使用各种食品级温和化学方法，如碱处理、酸处理和溶剂萃取法，来脱苦诸如库尔勒果皮渣和库尔勒果肉渣等副产物。在研究的各种化学处理方法中，丙酮溶剂萃取法从库尔勒果皮渣和果肉渣中提取柚皮苷和柠檬烯的效果最佳，且其提取物在食品产品开发方面具有较高的可接受性。该丙酮处理方法通过响应面法（RSM）进一步进行了优化，以实现柚皮苷和柠檬烯的最大提取量。在优化条件下，从库尔勒果皮渣中提取的柚皮苷和柠檬烯的最大提取量分别为 8.955、2.122 mg/g，从果肉渣中提取的最大量分别为 9.971、3.838 mg/g。该工艺不仅可以有效利用农业工业副产物，还可以为库尔勒果汁产业造成的环境污染提供可持续的解决方案。
