甘蔗糖蜜澄清处理及处理前后组分分析

甘蔗糖蜜作为糖厂生产过程中主要的副产品,含糖量高,且含有多酚和黄酮类等抗氧化性成分,可充分利用研制出高附加值的新产品。但由于糖蜜成分复杂,严重影响糖蜜深加工产品品质,因此需要有针对性地进行澄清处理去除胶体、杂质。文章糖蜜澄清处理分为稀释、絮凝、酸解等流程,通过单因素和正交实验,分析确定各工艺流程的条件。糖蜜6倍稀释,添加磷酸和絮凝剂絮凝沉淀,经高速离心机离心分离,收集上层清液。然后在100℃水浴,pH值为2的条件下酸解90 min,使糖蜜中蔗糖尽可能多地转化为还原糖。最后,测定糖蜜澄清处理前后组分含量变化,并采用GC/MS检测分析糖蜜澄清处理前后挥发性物质组分变化。

The pretreatment of sugarcane molasses and analysis on component

Sugarcane molasses was the byproduct of the sugar mill in process.It was an excellent source of mineral,and active ingredients like falconoid as well as polyphenol,which could be developed into high-added value product.However,the components of molasses were complicated,which would hinder the quality of the products.Therefore,some pretreatment was needed to get rid of the colloid and ash from the molasses.In present study,single-factor experiment and orthogonal experiment were designed to optimize the pretr...
