Embodiment 1
[0029] A plant selenium pressed candy, which comprises the following raw materials: cardamine, rattan tea, okra, and malt;
[0030] The preparation method of the plant selenium pressed candy includes the following steps:
[0031] Step one) Preparation of Cardamine-Vine Tea Extract:
[0032] 1) Mix the dried cardamine and rattan tea at a mass ratio of 1:1, and then pulverize at low temperature in a cooling system using cold water circulation, ice cubes or liquid nitrogen and dry ice as the cold medium, at ≤20℃ Crush and grind into a pulverized product with a fineness of 40 mesh under low temperature conditions; mix the pulverized product and water according to the weight of 1:5, and add 0.2wt% cellulase (100,000 U / g) and 0.2wt% Pectinase (50,000 U / g), heated to 60℃, pH6.8, enzymolysis time 2h, stirring speed 300rpm; after enzymolysis, heated to 85℃ to kill the enzyme;
[0033] 2) After enzyme inactivation, ultrasonic extraction for 90min, ultrasonic power of 300W, extraction temperatu...
