E 160a Beta-Carotene Using chromatography, by absorption on alumina or silica gel, pure beta-carotene shall give only one zone. E 160b Annatto, Bixin, Norbixin 1. Annatto shall be identified according to the following method and criteria: (
30. a)Dissolve a sufficient quantity of annatto in benzene or sufficiently dilute a benzene solution of annatto to obtain a solution of the same colour as 0.1 per cent. potassium dichromate solution. Pour 3 ml of the solution on the top of an alumina column: elute slowly. Wash the column three times with benzene. Bixin is very strongly adsorbed on the surface of the aiumina, forming a brilliant orange-red zone (which distinguishes it from crocetin). A very pale yellow zone usually moves very quickly down the column, even with pure crystalline bixin. The bixin cannot be eluted with benzene, petroleum either, chloroform, acetone, ethanol or methanol, but ethanol and methanol cause the orange colour to turn into an orange-yellow. (
31. b)Proceed as described in the preceding sub-paragraph, then remove the benzene from the column by washing three times with chloroform previously dried with potassium carbonate. After elution of the last, chloroform washing add 5 ml of Carr-Price reagent (antimony trichloride — a saturated solution in chloroform) at the top of the column. The bixin zone immediately turns blue/green (which distinguishes it from crocetin). This is knows as the Carr-Price reaction. 2. Bixin shall be identified according to the following method and criteria: Dissolve 1-2 mg of crystalline bixin in 20 ml of chloroform. Add 5 ml of this solution to the top of a suitable alumina column. Rinse the solution with chloroform previously dried with sodium carbonate. After elution of the last chloroform washing add 5 ml of Carr-Price reagent at the top of the column. The bixin zone immediately turns blue/green. 3. Alkaline solution of norbixin shall be identified according to the following method and criteria: Place 2 ml of an aqueous annatto solution in a 50 ml separating funnel. Add a sufficient quantity of 2N sulphuric acid to obtain a strongly acid reaction. Norbixin separates as a red precipitate. Add 50 ml of benzene and shake vigorously. After separation, discard the aqueous layer and wash the benzene solution with 100 ml of water until the solution is no longer acid. Centrifuge the solution (usually emulsified) of norbixin in benzene for 10 minutes at 2,500 revolutions per minute. Decant the clear norbixin solution and dry with anhydrous sodium sulphate. Add 3-5 ml of this solution to the top of an alumina column. Norbixin, like bixin, forms an orange/red zone at the surface of the alumina. Treated by the elutants benzene, petroleum ether, chloroform, acetone, ethanol or methanol it behaves like bixin and also gives the Carr-Price reaction described in sub-paragraph (
32. b)of paragraph 1 above. E 162 Beetroot Red or Betanin: Paper chromatography: With butanol saturated with 2N hydrochloric acid as solvent (ascending chromatography) betainin shall give a single red spot with a brownish trail and little migration. E 171 Titanium Dioxide: Substances soluble in hydrochloric acid: Suspend 5 g of titanium dioxide in 100 ml of 0.5N hydrochloric acid and heat for 30 minutes on a water bath, shaking occasionally. Filter through a Gooch crucible containing a three-layer filter bed — the first, coarse asbestos; the second, filter paper reduced to a pulp; and the third, fine asbestos. Wash with three successive 10 ml portions of 0.5N hydrochloric acid. Evaporate the filtrate to dryness in a platinum evaporating dish and heat to a dull red until the weight of the residue is constant. Weight of residue not more than 0.0175 g. Antimony: not more than 100 mg/kg. Zinc: not more than 50 mg/kg. Soluble barium compounds: not more than 5 mg/kg. E 172 Iron oxides and hydroxides: Selenium: not more than 1 mg per kg. Mercury: not more than 1 mg per kg.” GIVEN under the Official Seal of the Minister for Health this 21st day of September, 1981. EILEEN DESMOND, Minister for Health.
