Determination of bixin and norbixin in meat using liquid chromatography and photodiode array detection [PDF]
Food Additives and Contaminants - Part A Chemistry, Analysis, Control, Exposure and Risk Assessment, 2009 The development of an analytical method that enables routine analysis of annatto dye, specifically bixin and norbixin, in meat tissue is described. Liquid-solid extraction was carried out using acetonitrile. Analysis was by HPLC with photodiode array detection using two fixed wavelengths (458 and 486 nm). The possibilities of ion trap mass spectrometry

Norbixin binding to whey protein isolate - alginate electrostatic complexes increases its solubility and stability [PDF]
Food Hydrocolloids, 2020 Norbixin is a carotenoid extracted from the Annatto plant (Bixa orellana) and widely used as a natural colorant in pharmaceuticals, cosmetics and food. It is water-soluble at neutral and alkaline pH, but below neutral pH, norbixin starts to precipitate ...

Probing the binding between norbixin and dairy proteins by spectroscopy methods
Food Chemistry, 2013Annatto (norbixin) has been used to color cheeses for centuries, but there is very little knowledge about interactions between the pigment and dairy proteins. In this study, binding of norbixin with whey protein isolate (WPI), sodium caseinate (NaCN), and 6 individual dairy proteins was investigated by using fluorescence spectroscopy, Fourier transform

Short communication: Norbixin and bixin partitioning in Cheddar cheese and whey [PDF]
Journal of Dairy Science, 2014 The Cheddar cheese colorant annatto is present in whey and must be removed by bleaching. Chemical bleaching negatively affects the flavor of dried whey ingredients, which has established a need for a better understanding of the primary colorant in annatto, norbixin, along with cheese color alternatives.

Raman spectroscopic determination of norbixin and tartrazine in sugar
Food Additives and Contaminants - Part A Chemistry, Analysis, Control, Exposure and Risk Assessment, 2012In this paper, a method for the detection of norbixin and tartrazine in sugar by means of resonance Raman spectroscopy is presented. The extraction was done in four steps using methanol and the measurements were performed in aqueous solution. The excitation wavelength was 514 nm for norbixin and 488 nm for tartrazine samples.
