What To Know
- Noodles made with egg yolks will naturally have a yellowish hue due to the presence of lutein, a carotenoid pigment found in egg yolks.
- Noodles exposed to air for extended periods can undergo oxidation, causing the pigments in the flour to turn yellow.

Have you ever wondered why your noodles sometimes turn an unappetizing shade of yellow? This culinary mystery has perplexed noodle enthusiasts for generations. In this comprehensive guide, we will delve into the science behind noodle yellowing, exploring the various factors that contribute to this phenomenon.
Causes of Noodle Yellowing
The yellowing of noodles can be attributed to several factors, including:
- Egg Yolks: Noodles made with egg yolks will naturally have a yellowish hue due to the presence of lutein, a carotenoid pigment found in egg yolks.
- Oxidization: Noodles exposed to air for extended periods can undergo oxidation, causing the pigments in the flour to turn yellow.
- Additives: Some noodle manufacturers add artificial colors, such as turmeric or riboflavin, to enhance the appearance of their noodles.
- pH Levels: The pH level of the cooking water can also affect noodle color. Alkaline water can cause noodles to turn yellow, while acidic water can make them whiter.
- Wheat Type: Different types of wheat have varying levels of pigments. Noodles made with hard wheat tend to be more yellow than those made with soft wheat.
- Cooking Time: Overcooking noodles can also lead to yellowing due to the breakdown of pigments and the release of starch.
- Storage Conditions: Improper storage conditions, such as exposure to heat or light, can accelerate noodle yellowing.
