Abstract: The effects of ascorbic acid, adding sodium carbonate and sodium chloride on color-protection of pumpkin noodle were studied. The results of hue determination showed that adding ascorbic acid could make the natural color of pumpkin noodle enhanced, and had the best effect on the color-protection under the conditions of lighting. Among the factors of the orthogonal test, light period showed the most significant on decoloration of pumpkin noodle. Adding ascorbic acid and sodium carbonate contributed certain effects on the decoloration when they were added together.

Key words: ascorbic acid, pumpkin noodle, color-protection, hue determination
