Embodiment 1
[0015] Embodiment 1: with 10kg lotus seeds, the processing sequence is as follows:
[0016] (1) Preparation of lotus seed juice: Weigh 10kg of lotus seeds, grind them to 200 meshes by ultra-fine grinding, prepare a slurry with 90kg of boiling water, and then grind them to 10-50μm in a colloid mill. / min centrifuge for 5-8 minutes to obtain lotus seed juice.
[0017] (2) Liquefaction and enzyme inactivation: Add 0.1kg of a medium-temperature α-amylase with an activity of 1800U / g to lotus seed juice, keep the temperature at 60°C for about 25 minutes, and the viscosity of lotus seed juice is basically constant at 20-25mPa·s as a standard, and then inactivate the enzyme at 100°C for 5 minutes.
[0018] (3) Saccharification and enzyme inactivation: Add 0.02kg of β-amylase with an activity of 5000U / g to lotus seed juice, keep it at a constant temperature of 60°C for about 40min, and take the starch saccharification degree to reach about 65% as a standard; Inactivate the enzyme at ...

Abstract
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.
Description
technical field [0001] The invention relates to a preparation process of lotus seed solid beverage, which belongs to the field of food industry. Background technique [0002] Lotus seeds contain 18-20% protein, 60-62% carbohydrates, among which the average content of starch is 41%, fat 2%, ash 4% and a variety of microorganisms, not only rich in nutrition, but also contains many functional ingredients, such as Liensinine, nuciferine, luteolin, hyperoside, rutin and other flavonoids. Traditional Chinese medicine believes that lotus seeds have the functions of nourishing the liver and kidneys, improving intelligence and improving eyesight, and have good effects in treating vision errors, dizziness, tinnitus, heart failure, backache, soft knees, diabetes, etc. Long-term use has the effect of beautifying, anti-aging, and prolonging life. . [0003] my country is a big producer of lotus seeds. For a long time, lotus seeds are mainly dried and sold as the original fruit, which ...
