Wheat noodles are a staple food in most Asian countries and it can be estimated that noodles account for more than 12% of global wheat production (FAO, 2005; Nagao, 1995). Instant noodles are one of the most popular wheat noodles. In 2005, approximately 85 billion servings of instant noodles were eaten, and worldwide consumption continues to increase (International Ramen Manufacturers Association, 2006).
