TURMERIC OLEORESIN
Prepared at the 35th JECFA (1989), published in FNP 49 (1990) and in
FNP 52 (1992). Metals and arsenic specifications revised at the 59th
JECFA (2002). A tem
porary ADI established at the 30th JECFA (1986) was
not m
a
intained at the 35th JECFA (1989)
DEFINITION
Obtained by solvent extraction of turmeric (
Curcum
a longa
L.). Only the
following solvents may be used in the extraction: acetone, dichloromethane,
1,2-dichloroethane, methanol, ethanol, isopropanol and light petroleum
(hexanes).
The selection of a turmeric oleoresin of a particular composition is based on
the intended use in food. In general, all turmeric oleoresins contain
colouring matter and most contain flavouring matter but some oleoresins
are processed to remove aromatic compounds. Commercial products
include oleoresins (per se) and formulations in which oleoresin is diluted in
carrier solvents and which may contain emulsifiers and antioxidants.
Purified extracts of turmeric containing more than 90% total colouring matter
are subject to specifications for "Curcumin".
Turmeric Oleoresins are sold on the basis of "colour value" or "curcumin
content", which generally means the total content of the curcuminoid
substances: (I) curcumin, (II) demethoxycurcumin and (III) bis-
demethoxycurcumin
