“…The total phenolic content (TPC), the scavenging activity of ABTS cation and DPPH radical, ACE inhibition activity, α‐amylase and α‐glucosidase inhibition activity of undigested and digested control, CPP, and PNP‐added oat milk and yogurt extracts were determined spectrophotometrically according to the methods described in Aydemir et al. (2022) and (2014). All measurements were in triplicate.…”

The purpose of this study was to evaluate the addition of plant‐based peanut protein isolate (PNP) and commercial pea protein (CPP) on the quality of oat yogurt (OY). PNP and CPP were partially characterized for techno‐functional properties. PNP had higher solubility (acidic and basic regions) and emulsifying activity than CPP. The water absorption capacity of CPP is significantly (p < 0.05) higher than PNP. Amino acid profiles of PNP and CPP were promising for the nutritional enhancement of OYs. OYs with PNP or CPP (0.5, 1, 2% w/v) were stored for 21 days and compared to the control group with no protein. On the 21st day of storage, (i) PNP‐ or CPP‐added OYs were found to be comparable to the control with respect to post‐acidification and viscosity, (ii) syneresis was more evident in PNP‐added OYs than in CPP‐added ones, (iii) total color change of 1% CPP‐added OY was equal to the control, and (iv) hardnesses of control, 2% PNP, and 2% CPP‐added OYs were 0.29 ± 0.00, 0.39 ± 0.01, and 0.45 ± 0.00 N, respectively. No adverse sensory effects were detected for CPP or PNP addition. Both proteins increased the total phenolic, soluble protein, antioxidant, antihypertensive, and α‐glucosidase inhibition activity of oat milk and OYs, with PNP superior to CPP overall. Compared to oat milk, the fermentation process increased ACE inhibition activity in in vitro digested samples, whereas it reduced digested yogurts’ antioxidant activity. Utilization of PNP in OY can solve the waste problem of peanut producers and the texture problem of the OY producers while formulating a functional product.Practical ApplicationPlant‐based (PB) yogurts have a growing consumer demand. The low‐protein content of PB yogurts results in low acceptance with respect to their undesirable textural and sensorial attributes. This study provided a technical basis for the PB yogurt manufacturers focusing on the addition of commercial pea protein and isolated peanut protein into oat yogurt formulation without any thickeners or flavors. In vitro digestion of protein‐added oat milk and oat yogurts showed the benefits of fermentation on bioactivity to the consumers.
