[Study on secondary structural changes of protein in the formation of microcapsule by FTIR spectroscopy].

The mixture of whey protein and isolated soy protein with maltodextrin as microcapsules wall material was adopted. The secondary structure constitution of these two kinds of proteins in the process of heating and spray drying together with maltodextrin were studied by Fourier transform infrared spectra. The result showed that both whey protein and isolated… CONTINUE READING
