Development of Protein Rich Whey Beverage with Incorporation of Soy Protein and Pea Protein

Abstract

Aims: To develop protein rich whey beverage with incorporation of soy protein and pea protein Study Design:  Randomized design was used to make the formulations were prepared based on the three protein sources with three levels of their concentrations. Place and Duration of Study: Department of Food technology, Parul Institute of Applied Science and Department of Dairy and Food Technology, Parul Institute of Technology, Parul University, Vadodara, Gujarat India between November 2023 and April 2024. Methodology: The present study was carried out to incorporate soy protein concentrate and pea protein powder for the development of protein rich whey beverage. There were 3 levels of soy protein concentrate, 3 levels of pea protein powder and 3 levels of whey used in the obtaining 9 different formulations of whey beverages. The whey beverage was prepared using each combination and evaluated for sensory and physico-chemical properties including pH, acidity (% LA), protein content (%), Ash content (%) and Total solids content (%). The sensory evaluation was done based on 9-point hedonic scale for flavor, consistency, acidity and overall acceptability. Results: The results of sensory analysis showed that S4 (2 % soy protein concentrate, 1 % pea protein powder and 97 % whey) and S5 (2 % soy protein concentrate, 2 % pea Protein powder and 97 % whey) have significantly (p≤0.05) highest scores in all sensory attributes. The pH values were in range of 4.50±0.010- 4.85±0.001 for all sample combination, while acidity values were 0.128-0.148 % LA for all the samples. Based on the all physico-chemical analysis. The best formulation for whey beverage was obtained in S5 which contains the 2 % soy protein concentrate, 2 % pea Protein powder and 96 % whey providing highly nutrition components and valuable essential amino acids from all three protein sources Conclusion: The developed protein rich whey beverage has highly nutrition components and provides the valuable essential amino acids from all three protein sources. The developed protein rich beverage has very good market potential to all group of consumers.
