安全术语:如果接触眼睛,请立即用大量清水冲洗喝水并寻求医疗建议
物化性质:橙黄色结晶性粉末。有特殊臭。熔点179~182℃。不溶于水和乙醚,溶于乙醇、冰醋酸、丙二醇。碱性条件下呈红褐色,酸性则呈浅黄色。与氢氧化镁形成色淀,呈黄红色。与金属离子,尤其是铁离子,形成螯合物,导致变色。约5mg/kg铁离子就开始影响色素,10mg/kg以上时变为红褐色,染色能力降低,因此需选用适当容器。最好与螯合剂六偏磷酸钠、酸式焦磷酸钠共同使用。耐光性、耐铁离子性较差,耐热性较好。染着力强(特别是对蛋白质)。
每个分子结构中均有两个活性酚结构,故具有一定的抗氧化能力。
熔点:183 °C
相对密度:0.93
溶解性:Slightly soluble (hot)
用途:食用黄色色素。我国用于萝卜干、咖喱粉等已有很久历史。
日本用于咸菜、火腿、香肠以及苹果、菠萝、栗子的糖渍品。###可作为饲料着色剂,我国规定可用于糖果、果冻、冰淇淋和碳酸饮料,最大使用量为0.01g/kg。###A natural phenolic compound. Potent anti-tumor agent having anti-inflammatory and antioxidant properties. Induces apoptosis in cancer cells and inhibits phorbol ester-induced protein kinase C (PKC) ac
tivity. Reported to inhibit production of inflammatory cytokines by peripheral blood monocytes and alveolar macrophages. Potent inhibitor of EGFR tyrosine kinase and IB kinase. Inhibits inducible nit
ric oxide synthase (iNOS), cycloxygenase and lipoxygenase. Easily penetrates into the cytoplasm of cells, accumulating in membranous structures such as plasma membrane, endoplasmic reticulum and nucle
ar envelope.
Curcumin is currently being examined as a possible therapeutic for the treatment of Alzheimers disease (Chem. and Eng. News 90(31), 44 (2012)).
