The demand for the preparation of functional and nutrients-rich juice or beverages for the boosting immunity is the prime focus of consumers. So, this study was aim to optimization of different proportion for the preparation of blended juice from beetroots, grapes, turmeric, and lemons by using response surface methodology (RSM) and assessment of the quality parameters such as acidity, ascorbic acid, antioxidant activity and overall acceptability of blend juice were considered. Beetroot is widely recognized for its pigments known as betalains and have been utilized in the development of functional food and beverage products. Beetroots, grapes, turmeric, and lemons have been used in this study to prepare functional drinks, known for their nutritional value and medicinal properties. To optimize the blend juice, the dependent variables mainly beetroot juice, grapes juice, turmeric juice, and lemon juice in the range of 50–60, 30–40, 1–5, and 1–5 mL, were selected respectively. The optimized formulation for blended juice with a maximum desirability value of 0.921, an acidity of 0.60 %, an ascorbic acid of 14.17 mg/100 mL, an antioxidant activity of 93.94 %, and an overall acceptability of 8.07 was finalized at 53.12 mL of beetroot juice, 40 mL of grapes juice, 1.88 mL of turmeric juice and 5 mL of lemon juice.
