Embodiment 1
[0060] Embodiment 1: a kind of preparation method of Maca candy slice, comprises the following steps:
[0061] Step 1. Prepare maca extract:
[0062] 1.1) Preparation of Maca extract: Add the Maca medicinal material to the three extraction tanks A, B, and C of the countercurrent extractor of the tank group, add ethanol that is 8 times the weight of the medicinal material and has a volume fraction of 70%, and store at 60 ° C. Extraction, in the gradient formation stage, the extraction time of tank A is 5min and 15min respectively, and the extraction time of tank B is 10min; in the extraction stage, the extraction time of each tank is 2h; at the end of extraction stage, the extraction time is 2h; Liquid, get Maca extract;
[0063] 1.2) Pretreatment of the Maca extract: centrifuge the Maca extract at 6000r / min in an Alfa Laval disc centrifuge, collect the supernatant, and discard the sediment;
[0064] 1.3) Ceramic membrane filtration: The supernatant obtained in step 1.2) is s...
