Description:
<p>The study aimed to optimize the yield and ultrasonic extraction (UAE) conditions of phenolics from citral genotype basilleaves using response surface methodology (RSM) and to produce a functional beverage using the optimized extract (OE). Todevelop a functional drink formulation (FDM), OE was enriched with chlorophyll, ascorbic acid, and ribofavin. The modelwas found to be suitable for accurately predicting experimental results. The optimum conditions were 100% for amplitude,45 min for extraction time, and 1.06 g/100 mL for plant/solvent ratio. The TPC (mg GAE/g extract), radical scavenging (IC50mg/mL), and antidiabetic activities (IC50 mg/mL) were 262.40, 0.14, and 2.30 for the OE and, 292,176, 0.156, and 1.67 forFDM, respectively. After the enrichment process, the total chlorophyll of FDM was 3 times higher than OE, whereas totalcarotenoid content was negligible for both. Additionally, FDM was accepted by panelists in relation to overall acceptability,color, texture, favor, and aroma. The results of the study revealed that OE and FDM have promising antioxidant and antidiabetic activities due to their rich bioactive and fortifed compounds. Therefore, FDM can be used to provide health beneftsto diabetic patients and future consumers.</p><p>Keywords Sweet basil · Ultrasonic extraction · Functional drink · Antioxidant · Antidiabetic<br></p>
