甜菊糖苷生產(chǎn)工藝包括兩個(gè)主要過程：第一步采用水相提取甜葉菊葉，之后采用離子交換色譜法純化，產(chǎn)生甜菊糖苷初提物；第二部采用甲醇或乙醇進(jìn)行重結(jié)晶制得含量不少于95%的甜菊糖苷成品。

 

    甜菊糖苷為白色至淡黃色粉末，甜度大約為蔗糖的200至350倍（以5％的蔗糖相當(dāng)值），易溶于微溶于水。品質(zhì)指標(biāo)主要包括：總灰分≤1%，干燥失重≤6%（105°C，2h），不溶性固形物≤200mg/kg甲醇或5000mg/kg乙醇，砷≤1mg/kg，鉛≤1mg/kg。新條例自發(fā)布20日后生效。

 

    部分原文報(bào)道如下：

 

    The manufacturing process comprises two main phases: the first involving water extraction of the leaves of the Stevia rebaudiana Bertoni plant and preliminary purification of the extract by employing ion exchange chromatography to yield a steviol glycoside primary extract, and the second involving recrystallisation of the steviol glycosides from methanol or aqueous ethanol resulting in a final product containing not less than 95 % of the below identified 11 related steviol glycosides, in any combination and ratio.

 

    The additive may contain residues of ion-exchange resins used in the manufacturing process. Several other related steviol glycosides that may be generated as a result of the production process, but do not occur naturally in the Stevia rebaudiana plant have been identified in small amounts （0,10 to 0,37 % w/w）。
