Identification and quantification of anthocyanin pigments in colored rice

Anthocyanin pigments from varieties of black, red and wild rice were identified and quantified to evaluate their potential as nutritional function, natural colorants or functional food ingredients. Anthocyanin extraction was conducted with acidified methanol with 0.1M HCl (85:15, v/v) and identification of anthocyanin, aglycone and sugar moieties was conducted by comparison with purified standards by HPLC, Ultraviolet-Visible absorption spectrophotometer and paper chromatography. Black and wild rice showed three different types of pigments by HPLC whereas red rice variety did not show any anthocyanins. Out of three pigments detected, one (peak 2) was characterized as cyanidin-3-glucoside (C3G) by comparison of spectroscopic and chromatographic properties with an authentic standard, and another (peak 3) was tentatively identified as cyanidin-fructoside on the basis of spectroscopic properties with λ_max of aglycone in 1% HCl methanol at 537 nm, electrospray ionization mass spectra with major ions at 449 and 287 m/z and chromatographic properties. But another pigment (peak 1) has not been characterized. The most abundant anthocyanin in black and wild rice was C3G.

玻璃着色剂对可切削渗透陶瓷复合体颜色影响的研究

目的 观测不同配方的玻璃着色剂对可切削渗透陶瓷（MIC）复合体颜色的影响。方法 确定渗透玻璃基本组分。测定其光学指数：色散值0.068 41（435.8-656.3 nm）,折射率1.596 91（587.6 nm波长）。以基本配方为核心调整形成5种着色剂配方的渗透玻璃。将它们渗透到氧化铝圆片状试件中,TC-PIIG型色差计分别测量5种MIC复合体的L*、a*、b*值并与Vita In-ceram陶瓷颜色系数比较。结果 不同着色剂配方的MIC颜色体系的的主要区别在L*值,其次是a*值,b*值变化较小。MIC颜色体系L*值为64.55-71.46,a*值为3.35-7.38,b*值为10.00-12.41,Ca*b*11.38-13.95,ha*b*54.07-73.00。与Vita In-ceram陶瓷色系颜色参数接近。结论 渗透玻璃着色剂配方的改变主要影响渗透陶瓷复合体颜色表达的明度和色相,对彩度的影响相对较小,其颜色表达符合临床应用要求。

Food preservatives sodium benzoate and propionic acid and colorant curcumin suppress Th1-type immune response in vitro

Food preservatives sodium benzoate and propionic acid and colorant curcumin are demonstrated to suppress in a dose-dependent manner Th1-type immune response in human peripheral blood mononuclear cells (PBMC) in vitro. Results show an anti-inflammatory property of compounds which however could shift the Th1–Th2-type immune balance towards Th2-type immunity.
