Oat grain thick slurry product and preparation method thereof

The invention provides an oat grain thick slurry product and a preparation method thereof. The preparation method comprises the following steps: soaking the raw materials; grinding the wet material into thick liquid; keeping enzymolysis; separating slurry and residues; enzyme deactivation; degassing is performed; performing homogenizing; cooling and storing; preparing materials; performing ultrahigh-temperature sterilization; the step of grinding the wet material into thick liquid comprises primary thick liquid grinding and secondary thick liquid grinding, so that primary oat thick liquid and secondary oat thick liquid are obtained in sequence. The method can effectively reduce the wear degree of the mill, maximally preserves the nutritional ingredients of the oat raw material, improves the protein yield, reduces the precipitation in the shelf life, and effectively improves the product quality. 本发明提供一种燕麦谷物浓浆产品及其制备方法。所述制备方法包括以下步骤：原料浸泡；湿料磨浆；酶解保持；浆渣分离；灭酶；脱气；均质；冷却贮存；配料；超高温灭菌；以及灌装，其中，所述湿料磨浆的步骤包括一次磨浆和二次磨浆，以依次获得一次燕麦
