摘要:楊梅核中含有對人體有益的黃酮,為充分利用楊梅植物資源，探討如何制作楊梅核奶糖,以及楊梅核總黃酮的最佳水浴提取方法.以楊梅核為原料,直接加入奶糖原料,根據奶糖工藝制作出奶糖.還設計正交實驗,采用乙醇水浴提取法從楊梅核中提取黃酮類物質,并對所提取的黃酮類物質進行驗證，用分光光度法測定其含量,最后根據奶糖的加工工藝制作將黃酮用逐級稀釋辦法加入奶糖,制作出黃酮保健奶糖.
實驗結果表明楊梅核難和其他奶糖原料溶于一體,而采用提取黃酮加入奶糖是制作楊梅核奶糖的最好方法，加入總黃酮后,會使奶糖顏色變淺,增加硬度,而且水浴的最佳提取方案為：80%乙醇于60℃水浴提取3 h，所得總黃酮的浸出率最高。

Abstract :Flavonoids in the waxberry pit is beneficial to human body, in order to well make use of the plant resources in the waxberry, study how to make the waxberry toffee, and the best method to extraction flavonoids from waxberry . take waxberry pit as material, and put the material, of which are using in toffee-processing directly into the waxberry pit material, produce the toffee according to the toffee-processing technics.At the same time, design the Orthogonality Expreiment. And use Ethanol to extract the flavonoid from the waxberry pit, do verifying of the flavonoid, which is extracted from the waxberry pit. Use absorp-tion of the ultraviolet to test the flavonoid content, At last, use the dilute method to add the flavonoid into the toffee grandually according to the toffee processing technics. Then we can obtain the waxberry pit toffee, that is health flavonoid toffee.
Experiment result is that waxberry pit can not dissolve well with the toffee materials, use extracted flavonoid and add into the milk suguar is the best way to process the waxberry pit toffee ,and the color of sugar was changed by flavonoid, the best extraction plan to obtain the flavonoid is use 80% ethanol in the 3 hours calefaction at 60 ℃ water bathses.
