Embodiment 1
[0030] The concrete preparation method of health-care non-transgenic sweet potato powder comprises the following steps:
[0031] (1) Wash the sweet potato (Yushu 17, place of origin: Pengshui County, Chongqing City) with clean water, drain, crush to 10 mesh, and then freeze-dry at -30°C for 10 hours to obtain dry powder;
[0032] (2) Add the dry powder to a superfine pulverizer (SQW-6A superfine pulverizer provided by Shandong Sanqing Stainless Steel Equipment Co., Ltd.) for superfine pulverization to 5 μm to obtain a superfine powder;
[0033] (3) adding the superfine powder into the enzyme solution with a temperature of 45° C. and stirring at a speed of 400 rpm for 4.5 hours, and then performing centrifugation in a centrifuge with a speed of 3800 rpm for 10 minutes to obtain a broken wall powder;
[0034] (4) Vacuum-dry the broken-wall powder at 60°C for 10 hours, then sterilize it by ultraviolet irradiation, and the irradiation dose is 350J / m 2 , and the irradiation time w...
Embodiment 2
[0040] It is basically the same as in Example 1, except that the compound enzyme is obtained by stirring and mixing evenly with glucoamylase and β-glucosidase at a mass ratio of 1:1. Obtain the health-care non-transgenic sweet potato powder of embodiment 2.
Embodiment 3
[0042] It is basically the same as Example 1, except that the compound enzyme is obtained by stirring and mixing uniformly with β-amylase and β-glucosidase at a mass ratio of 1:1. Obtain the health-care non-transgenic sweet potato powder of embodiment 3.
