Abstract

The invention discloses premna cavaleriei levl. fresh leaf selenium-rich Shenxian bean curd and a preparation method thereof, and belongs to the technical field of food processing. The bean curd comprises premna cavaleriei levl. fresh leaves, vine tea extract liquid and alkaline water. The method comprises the steps of heating the vine tea extract liquid to 85-95 DEG C, adding the premna cavaleriei levl. fresh leaves, fully mixing the components, and repeatedly rubbing and kneading a mixture until the kinematic viscosity of premna cavaleriei levl. fresh leaf filter pulp is 5,000-10,000 mm<2>.s; performing filtration by a screen; adding the alkaline water into filtrate, and stirring the components uniformly; and performing room-temperature standing for solidification forming. The prepared Shenxian bean curd is fresher and more jade green, and is better in taste; and the bean curd is fuller in nutrition, and contains selenium, amino acid, vitamin and various human necessary trace elements of selenium-rich vine tea in addition to pectin and flavone substances of premna cavaleriei levl., so that the types of nutrients are enriched and the increasing healthy demands of consumers can bebetter met.
