The number of starch lumps in the cooked rice noodle (Fig. 2C and D) was lower than that before cooking (Fig. 2A and B) but the size of each starch lump increased. This may be attributed to the swelling of starch from penetrated water. After cooking, the pattern of protein distribution in both noodles was unchanged. The separated small groups of protein in noodle without NaCl were clearly visible while a well-developed protein network was still found in noodle with NaCl.
