The invention relates to a process for preparing
lotus seed
solid drink and belongs to the field of
food industry. The preparation process comprises: a step of preparing
lotus seed, which is to crush
lotus seeds into supermicro
powder of a grain size of 200 meshes, screen, blend with water for making pulp, finely mill by a
colloid mill to 10 to 50 micrometers, heat, cool and gelatinize, separate by a
centrifugal separator and obtain lotus seed juice; a step of liquefying and inactivating
enzyme; a step of saccharifying and inactivating
enzyme; a step of separation and homogenizing; a step of vacuum concentration; a step of
spray drying; and a step of screening and packaging. The technical indexes of the lotus seed
solid drink include yellowish or milky white color, uniform and non-
agglomerate particles, quick
dissolution speed,
protein content of more than or equal to 20 percent,
water content of 2 to 5 percent,
bacterial colony density of less than or equal to 1,000cfu / g, coliform group density of less than or equal to 30MPN / 100g, and no
pathogenic bacteria. The powdered lotus seed
solid drink prepared by the process has the characteristics of simplicity of blending, good taste, rich
nutrient, convenience for carrying and taking, long storage period and the like, and is a new variety of lotus seed product.
