温州蜜柑，又名温州蜜橘，含有大量的多酚和抗氧化剂。本研究主要针对食品添加剂中生物活性物质的生物废弃物进行了研究。为此，采用了超声波提取法。测定了温州蜜柑提取物的抗氧化能力和多酚含量。采用响应面方法(RSM)和粒子群算法(PSO)减少了实验次数。因此，提取过程变得更加经济。在本研究中，根据RSM，确定了最优条件：90min，56%幅度，50℃。PSO提出的最佳条件是：27min，50幅度，52℃。丹参总酚含量为8.953 GA/g果皮，儿茶素含量为5.253 g/g果皮。酚类和类黄酮的含量分别为6.977 GA/g果皮和6.454 GA/g果皮。RSM获得的TPC(0.9947)和TFC(0.9825)的R值最高。结果表明，温州蜜柑果皮中含有丰富的酚类物质和高附加值的生物活性物质。
Satsuma mandarin, which is also known as Citrus unshiu, contains high amount of polyphenols and antioxidants. This study focused on the biowaste valorization of bioactive compounds used for food supplementary. For this purpose, ultrasonic extraction method was utilized. The antioxidant capacity and polyphenolic content of the Citrus unshiu extracts were determined. The number of experiments was reduced owing to the response surface methodology (RSM) and particle swarm optimization (PSO). Therefore, the extraction process has become more economical. In this study, according to the RSM, optimal conditions were determined as 90 min, 56% amplitude, and 50 degrees C. PSO suggested the optimal conditions as follows: 27 min, 50 amplitude, and 52 degrees C. For the performance metrics, RSM gave higher satisfactory results than PSO. For RSM, 8.953 GA/g-peel and 5.253 catechin/g-peel were obtained as total phenolics content (TPC) and total flavonoids content (TFC). For PSO, 6.977 GA/g-peel and 6.454 catechin/g-peel were obtained as phenolics and flavonoids. The highest R-values for TPC (0.9947) and TFC (0.9825) were obtained by RSM. The results proved that Citrus unshiu peel contains highly rich phenolic and high value-added bioactive compounds.
