將甜菊葉去梗并粉碎，有利于除去梗中所含部分雜質(zhì)；粉碎后的粉末與葉子比，增加了接觸面積，更有利于浸提。溫度選擇60℃為佳，高于60℃可能促進甜菊糖苷水解而降低得率；且熱水加樣比冷水加樣更有利于浸提。這是因為細胞中的水解酶和微生物對甜菊糖苷有分解作用，熱水加樣可以殺菌、殺酶、避免了甜菊糖苷水解，從而提高提取率

活性炭加入過多，會使部分甜菊糖被吸附掉，造成損失；若加入過少，則脫色效果不明顯。按糖液體積2%的量加入活性炭，用磁力攪拌器攪拌40min。用濾紙，微濾膜各抽濾2次，除去活性炭。得到的糖液近似為無色。

The stevia leaves were smashed with their peduncles removed, which would eliminate the impurities contained in the peduncles; comparing with the leaves, the powders had more contact areas, being easy to be leached. 60℃ is the best temperature, above which the hydrolyses of the stevia glucosides could be improved, decreasing the yield; and the hot-water is better than the cold-water, in the aspect of improving the leaching. This is because the hydrolases and the microbes in the cells had a decomposition action to the stevia glucosides, and the hot-water could kill the bacteria and the enzymes, which avoided the hydrolyses of the steiva glucosides and improved the extraction ratio.

Too much activated carbon would absorb some stevias and cause a loss; but too little activated carbon would make the decoloration less obvious. The activated carbon was added by 2% of the volume of the sugar liquid, stirred for 40 min using the magnetic stirrers. The activated carbon was eliminated by filterations two times each using the filter papers and micro filter membranes, getting the almost colorless sugar liquid.
