| Abstract Whey is well-known for the functional and bioactive properties of its proteins and peptides, which are of great interest to food and nutraceutical industries. The aim of this study was to investigate the effect of four different commercial proteases (Novo ProD® (NPD), Alcalase® (ALC), Pancreas Trypsin® (TRY), and Flavourzyme® (FLA)) in the generation of hydrolysates with emulsifying and antioxidant activities. Hydrolysis processes were carried out for 5 h, reaching maximum degrees of 18.5, 15.5, 9.2, and 8.7% for NPD, ALC, TRY, and FLA, respectively. All tested enzymes generated very diverse, but conservative peptide profiles when comparing the treatments along the time, with the main enzymatic actions up to 120 min-reaction. An increase in the... |

| In this work, alginate-whey protein was used as wall materials for encapsulating Lactobacillus delbrueckii subsp. bulgaricus (L. bulgaricus). The characteristics of encapsulated and free L. bulgaricus showed that the free L. bulgaricus lost viability after 1 min exposure to simulated gastric fluid (SGF) at pH 2.0 and 2.5. However, the viability of encapsulated L. bulgaricus did not decrease in SGF at pH 2.5 for 2 h incubation. The viable numbers of encapsulated L. bulgaricus decreased less than 1.0 log unit for 2 h incubation in SGF at pH 2.0. For bile stability, only 1.2 log units and 2.0 log units viability of the encapsulated L. bulgaricus was lost in 1 and 2% bile for 1 h exposure, respectively, compared with no survival of free L. bulgaricus under the... |

| Abstract This research investigated the interaction between chitosan and whey protein molecules in terms of pH and heating. The FTIR, rheological analysis, turbidity, and zeta potential measurements were used to assess this interaction. At pH 4.0, addition of low amount chitosan with chitosan/whey protein isolate (C/WPI) ratio of 1:5 effectively prevented the denaturation of whey proteins after heating, whereas high amount of chitosan (C/WPI,1:2) led to depletion flocculation. The combination of chitosan and whey proteins was electrostatic attracting at pH 5.5 and 6.0. At low chitosan addition, the complexes formed at pH 5.5 showed higher viscosity and the complexes formed at pH 6.0 showed a shear-thinning behaviour. At high chitosan addition, the... |

| Abstract Protein enrichment of bakery products not only improves protein ingestion, but also compensates for the deficiency of certain limiting amino acids in these products. However, the addition of protein sources can greatly influence the characteristics of the dough and, consequently, process and product parameters. Thus, the objective of this work was to evaluate the rheological behavior of wheat flour doughs enriched with whey and collagen protein hydrolysates. Both hydrolysates influenced rheological properties of wheat flour doughs. They reduced water absorption and increased arrival time and dough development time, but caused a weakening of the dough when compared to the control. However, a greater influence of collagen hydrolysate was observed... |
