    • 摘要: 研究比较了常规亚硫酸法工艺与碳磷无硫工艺在制糖清净过程中的实际应用效果和白砂糖质量情况,结果表明:碳磷无硫工艺清混汁纯度差较亚硫酸法提升了1个百分点,碳磷白砂糖中未检出SO2,混浊度从亚硫酸法的110 MAU降低至49 MAU,高品质糖产率从亚硫酸法的1.63%提升至54.21%,较好地体现了碳磷无硫工艺的技术优势,对提高糖分回收率和产品质量具有非常积极的作用.通过技改实现亚硫酸工艺向碳磷工艺的转变,不仅可提升企业的经济效益和质量效益,还提高了制糖副产物的综合利用价值,取得了较好的环境效益,具有很好的推广应用价值.

    • 摘要: 分析无硫澄清工艺的清汁、糖浆与白砂糖理化指标,并通过T检验分析这些物料理化指标与亚硫酸法的差异显著性.同时分析无硫澄清工艺过程Ca3(PO4)2、CaCO3及单宁钙协同CaCO3等沉淀物微观结构及吸附蔗汁胶体、色素效果,探讨无硫澄清的除杂脱色原理.结果表明,无硫澄清工艺清汁和糖浆在纯度、色值、还原糖含量等指标T检验p值均大于0.05,而清汁浊度、糖浆电导灰分及浊度的p值小于0.05,表明无硫澄清工艺与亚硫酸法工艺清汁、糖浆在纯度、色值、还原糖含量等关键指标无显著差异,在清汁浊度、糖浆浊度与电导灰分存在显著性差异;所煮制白砂糖不含SO2,色值为46 IU,浊度21 MAU,水分0.07%,电导灰分0.024%,色值与浊度明显优于亚硫酸法(色值62 IU,浊度38 MAU,表明无硫澄清工艺完全可以满足一级白砂糖生产的工艺要求,且在色值与混浊度更具有优势.从扫描电子显微镜图可知,纯水体系生成的CaCO3、Ca3(PO4)2和单宁钙沉淀具有明显的晶体结构,晶体间存在许多空隙,且在蔗汁体系生成CaCO3、Ca3(PO4)2及单宁钙沉淀晶体间绝大多数空隙已全部或大部分被填充,特别单宁钙,空隙数量已显著减少,甚至观察不到,表明上述沉淀物生成时会同步吸附混合汁的胶体、色素等形成共沉淀,从而将它们除去,胶体去除率与脱色率达到46.17%和50.61%,优于亚硫酸法,这可由清汁、糖浆及白砂糖紫外全波扫描图证实.

The structural characterizations of tannin precipitation and CaCO3 formed in pure water and sugarcane juice were both studied by scanning electron microscopy (SEM). The results indicated that the pigment quantity and unsaturated bonds of pigment in cane juice were reduced by tannin precipitation and CaCO3, which resulted in high decolorization. The tannin precipitation and CaCO3 were of porous structure, and could absorb colloids and pigments of cane juice to formed co-precipitation, resulted in excellent clarification effect.
