摘要
The present invention pertains to pregelatinized modified, high amylose starches that are batch cookable to a uniform, substantially particle-free dispersion at atmospheric pressures and the process of preparing such starches in an extruder. Such pregelatinized, modified, high amylose starches are useful in a variety of applications without the need for jet cooking. In addition, such starches are readily dispersible at high solids to provide uniform formulations and are substantially non-retrograded. Further, such starches provide improved surface sizing agents which use results in the preparation of paper which is characterized by improved water resistance, reduced porosity, and other size properties.
