[0060] Example 3 Determination of Reasonable Addition of Black Rice Leaf Extract

[0061] Several experiments were carried out to adjust the addition amount of the leaf extract of black rice tree. The amount of other raw materials is as shown in Table 1, and the balance is water. No debittering treatment was carried out on the leaf extract of the black rice tree, and the other steps of the preparation method were as in Example 1 to obtain a frozen drink. The purpose is to obtain the reasonable dosage of the leaf extract of Wufan tree, the results are shown in Table 1 below.
