The traditional Chinese dumpling, jiaozi, has a long history and is widely consumed in East and Southeast Asian countries. Jiaozi has become a staple food in China because of the rapidly growing frozen food industry. Wheat flour is the dominant ingredient used in making jiaozi wrappers. High-quality jiaozi wrappers are evenly hydrated, smooth surfaced, white or milky white in appearance, elastic and extensible, with low stickiness. This article briefly describes jiaozi, its processing, and its flour quality requirements.
