powder. According to the preparation method, the blueberries and the Lycium chinensis are subjected to vacuum
freeze drying and are ground into blueberry coarse
powder and Lycium chinensis coarse
powder, the blueberry coarse powder and the Lycium chinensis coarse powder are sieved to obtain blueberry
fine powder and Lycium chinensis
fine powder, and the blueberry
fine powder and the Lycium chinensis fine powder are added into
fresh milk so as to prepare the blueberry-Lycium chinensis yoghourt, so that the loss of
nutrient contents of the blueberries and the Lycium chinensis is avoided, and the
nutrient contents of the blueberries and the Lycium chinensis are adequately utilized. Compared with the prior art, the preparation method has the advantages that the blueberry residue and the Lycium chinensis residue are not discarded, and by virtue of the vacuum
