Specific absorbance E 1%/1cm(454nm) :62 Ratio of absorbance (E454nm/E482nm) : 1.16 Loss on drying (80 deg. C) : 0.4% Residue after ignition (as sulfate) : 4.8% Thin layer chromatography test : Passed Norbixin :1.8% 上海惠诚生物科技有限公司自2010年成立以来,一直致力于为客户提供试剂,...
Its basic structure consists of a complex mixture of carotenoid pigments, primarily bixin and norbixin. This compound is insoluble in water but soluble in oil and alcohol. Annatto is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) and is widely used in ...
The aim of this work was to determine (1) the total phenolic compound (TPC), total flavonoid compound (TFC) and bixin and norbixin content of polar extracts of leaves (ALE) and seed (ASE) from annatto (Bixa orellana L.); (2) the antioxidant activity, the ALE and ASE by means of ...
The objective of the present study was to evaluate the potential sensitizing effects of an annatto extract (containing both bixin and norbixin), and if positive, to determine which of the carotenoid pigments (i.e. bixin and norbixin) are sensitizers. Thus, both the irritancy effects and the ...
All these absorption peaks can be ascribed to the carotenoid compounds of the annatto (bixin and norbixin). Additionally, no significant spectral differences were observed between the annatto and the UF annatto, indicating the UF process did not alter the chemical characteristics of the compound. In...
