    • The present invention relates to a fixed bed decolorization process for an polyunsaturated fatty acid, comprising a polyunsaturated fatty acid or a polyunsaturated fatty acid solution is either passed directly through a filler of the fixed bed or recycled in a filler of the fixed bed, a colorless or light-colored polyunsaturated fatty acid product is ultimately produced, at the same time, other than the color, other qualities of the polyunsaturated fatty acid remain unaffected. The decolorization process allows continuous operation or intermittent operation. The filler of the fixed bed comprises one or a mixture of activated carbon, diatomite, carclazyte, silicone and an ion-exchange resin. An upper or a middle or a bottom or a combination thereof is employed to feed a polyunsaturated fatty acid feedstock or a polyunsaturated fatty acid solution. The filler in the fixed bed can be used repeatedly. The filler can be reused after being washed when decolorization effects thereof become deteriorated or ineffective.
    • 本发明涉及用于多不饱和脂肪酸的固定床脱色方法,其包含多不饱和脂肪酸或多不饱和脂肪酸溶液直接通过固定床的填料或循环到固定床的填料中,无色 或最终产生浅色多不饱和脂肪酸产物,同时,除了颜色之外,多不饱和脂肪酸的其他品质不受影响。 脱色过程允许连续操作或间歇操作。 固定床的填料包含活性炭,硅藻土,carlozyte,硅酮和离子交换树脂中的一种或混合物。 采用上部或中部或底部或其组合来供给多不饱和脂肪酸原料或多不饱和脂肪酸溶液。 固定床中的填充物可以重复使用。 当其脱色效果变差或无效时,填料可以在清洗后重新使用。

    • The invention discloses a method for preparing high-content zeaxanthin. In the conventional preparation methods, some methods adopt certain toxic organic solvents; some methods require the multi-step crystallization process; and some methods are featured by long reaction time, high temperature and lower product yield, thus being not suitable for industrial production. The invention adopts lutein crystal or its fatty acid ester as the raw material and utilizes isomerization reaction to produce zeaxanthin, and is characterized in that a mixed catalyst consisting of an organic base catalyst and a cocatalyst is used in the isomerization reaction, wherein the cocatalyst is palladium carbon. The invention has the advantages of simple process route, low reaction temperature, short reaction time, good product purity and high yield, thus being suitable for industrial production, and no poisonous and harmful organic solvent residues in the product, thus being suitable for the use as a food additive or drug.
    • 本发明公开了一种高含量玉米黄质的制备方法。 在常规制备方法中,有些方法采用某些有毒有机溶剂; 一些方法需要多步骤结晶过程; 有些方法反应时间长,温度高,产品收率低,不适合工业化生产。 本发明采用叶黄素结晶或其脂肪酸酯为原料,利用异构化反应生成玉米黄素,其特征在于在异构化反应中使用由有机碱催化剂和助催化剂组成的混合催化剂,助催化剂为 钯碳。 本发明工艺路线简单,反应温度低,反应时间短,产品纯度高,收率高,适合工业化生产,产品无有毒有害有机溶剂残留,适合用途 作为食品添加剂或药物。
