and chemical characteristics
Appearance and
Properties:Orange yellow or dark yellow
powder, whose color varies from
primrose to scarlet and which is fairly soluble in water,
ethyl alcohol
and propylene glycol, but insoluble in fat. The water solution of
the pigment is of bright and vivid yellow hue, and appears in
weak acidity or alkalinity.
PH:The environmental PH value
has little influence on its hue. At PH 2.**6.0, it becomes a
little unstable; at PH 7.0 or above, it is stable and you can
maintain stable yellow; at PH value of 4.**6.0 or 8.***1.0, it
gets more stable than β-carotene.
Stability:The
pigment is strongly resistant of reduction, microbial resistance,
light fastness, heat resistance, and has good resistance to metal
ions because its color, within the PH value of ***1, is
essentially the same;
Reactivity:Metal ions
have no influence on it but in the case of iron, it becomes
black.
An Overview of the
Risk：Extracted
