| Popis: | In this study, whey protein concentrate (WPC) and xanthan gum (XG) hydrogels were developed with cooperation of basil seed nanoparticles (BSG NPs) (1 and 3%), two different levels of salt (150 and 300-mM CaCl2), and acidic pH (3.5). The five types of hydrogels were synthesized and characterized mechanically and morphologically using different methods such as SEM, swelling ratio, DSC, WHC, and texture analysis. The results showed that the hardness and consistency of the hydrogel system reached the most at the WPC–XG (300-mM CaCl2) among the samples. The hardness was 931.83 g, and the consistency was 28297.8 g s. For WHC analysis, WPC–XG (150-mM CaCl2) sample got the highest rate of the WHC (%) at 95.39%. The highest rate of swelling ratio was attributed to WPC–XG (BSG NPs 3%) composite. From DSC analysis, the highest peak temperature (Tp) at 114 °C relates to WPC–XG (BSG 3%), the highest onset temperature (To) at 99 °C, relates to WPC–XG (BSG 1%), and the sample containing WPC–XG (150-mM CaCl2). The highest value of enthalpy of gelatinization (ΔH) belongs to WPC–XG (BSG NPs 3%) samples. |
