Impact of protein ratio and thermal treatment on the aggregation and rheological properties of high-concentrated milk and pea protein suspensions.

The association of pea proteins (PP) with a more consumer-accepted product, such as milk, is considered as a strategy to improve plant protein consumption. This study investigates the physicochemical and rheological properties of mixed milk protein (MP): PP systems at different protein ratios (100:0, 80:20, 60:40, 40:60, 20:80, 0:100, MP:PP) in high-concentrated protein systems, before and after thermal treatment. The results showed that MP, represented by casein, and PP form independent networks with rheological behavior dependent on the major protein fraction involved in the mixture.
