Figure 2.

The microstructure of the six yogurt samples. Representative images are shown for the Reference, Soy, Coconut, Berry, Cookies, and Drinkable yogurts, labelled at the top of each column; see Table 3 for corresponding sample composition. The fat appears red in these images and the protein appears green, black unstained areas are the serum pores and other unstained ingredients including carbohydrate and stabilizers. Lower magnification images appear in the upper row, where the scale bars are 50 µm in length and higher magnification images of the same samples appear in the bottom row, where the scale bars are 10 µm in length.
