摘要

阴蒂,也被称为蓝豌豆花(当地名称:bunga telang),由于其大量的生物学和药理特性而引起了研究人员的兴趣。它富含花青素,被广泛用作天然食用色素。然而,活性化合物稳定性差可能会影响其治疗效果并限制其在制药和食品工业中的应用。因此,本研究旨在研究微波包封对阴蒂花提取物花青素、抗氧化剂和总酚含量的影响。以不同配方的阿拉伯胶(GA)和麦芽糖糊精葡萄糖(MD)为载体材料,在40% ~ 70% W /v的微波功率下(300、450、600 W)进行微波辅助包封(MAEC)。分析了制剂中总酚含量(TPC)、抗氧化活性和花青素含量。结果表明,增加微波功率可提高TPC和抗氧化活性(P<0.05)。而加入浓度在60%以上的载体材料,则降低了微波包封花青素的TPC和抗氧化活性。微波辅助CTFE包封的最佳条件为:微波功率为600 W,载流子GA/MD浓度为50% W /v(比例为1:1)。随着微波功率的增大和载体物质浓度的降低,花青素保留率、抗氧化活性和TPC显著增加(P<0.05)。MAEC方法提高CTFE中花青素的稳定性,在扩大其作为高附加值天然着色剂的应用方面具有很大的潜力。

Effects of Microwave Power and Carrier Materials on Anthocyanins, Antioxidants, and Total Phenolic Content of Encapsulated Clitoria ternatea Flower Extract
Clitoria ternatea, also famously known as the blue pea flower (local name: bunga telang), has attracted interest among researchers due to its plethora of biological and pharmacological properties. It is rich in anthocyanin and widely used as a natural food colourant. However, the poor stability of active compounds may affect the therapeutic benefits and limit their application in the pharmaceutical and food industries. Hence, this work aims to study the effects of microwave encapsulation on the anthocyanins, antioxidants, and total phenolic content of Clitoria ternatea flower extract (CTFE). Microwave-assisted encapsulation (MAEC) was carried out at three different powers (300, 450, and 600 W) with different formulations of Gum Arabic (GA) and Maltodextrin Dextrose (MD) as carrier materials from 40% to 70% w/v. The total phenolic content (TPC), antioxidant activity, and anthocyanins in encapsulates were analysed for the formulations. The findings showed that increased microwave power increased TPC and antioxidant activity (P<0.05). However, adding carrier materials concentration above 60% reduced TPC and the antioxidant activity of microwave-encapsulated anthocyanin from CTFE. The best microwave-assisted encapsulation conditions of CTFE were found at 600 W microwave power with 50% w/v carrier materials GA/MD (ratio 1:1) concentration. The retention of anthocyanins, antioxidant activity, and TPC increased significantly (P<0.05) with increased microwave power and lower concentration of carrier materials. The MAEC approach to enhance the stability of anthocyanin in CTFE presents a high potential to expand its application as a high-value-added natural colourant.
