beta-Carotene Usage And Synthesis
Descriptionb-Carotene is applied as a food coloring additive, as provitamin A in food and feed, in multivitamin products, as an antioxidant, and as a colorant for cosmetics. In the literature, a number of microorganisms are described that are capable of accumulating b-carotene up to relatively high levels, for example, the fungi B. trispora, Phycomyces blakesleanus, the yeast Rhodotorula glutinis, and the above-mentioned alga D. salina. Production processes were developed with mutants of B. trispora in the former Soviet Union (cf. Sect. 2.3) and for D. salina.
Among the b-carotene–producing algae, D. salina is currently the best-known and most efficient producer: D. salina cells are able to synthesize b-carotene in levels a thousand times higher than those of carrots. Dunaliella is also able to synthesize a-carotene, violaxanthin, neoxanthin, zeaxanthin, and lutein. The unicellular green alga D. salina is grown in open ponds without (hardly any) process control. It was shown that the highest production levels were obtained with high light intensities, nitrogen limitation, and stress-inducing temperatures. This has resulted in b-carotene levels up to 12 % of the dry mass. The production facilities are located in places where optimum conditions are found, namely in Australia, Israel, and in the United States; these places benefit from a lot of sunshine, little cloudiness, the availability of saline water, and high average temperatures.
Chemical Propertiessolid
Usesantioxidant; provitamin A
UsesMost important of the provitamins A. Widely distributed in the plant and animal kingdom. In plants it occurs almost always together with chlorophyll. Vitamin A precursor. Ultraviolet screen
Usesbeta-carotene is a known anti-oxidant. It has demonstrated photo protection properties particularly when taken internally. It is also used as a yellow-orange color additive. Beta-carotene is a caratinoid and a precursor to vitamin A. It is beneficial for dry and flaking skin. naturally occurring in fruits and vegetables that contain orange-yellow pigment, such as apricots, carrots, mangoes, and oranges, beta-carotene can also be synthetically manufactured.
UsesBeta-Carotene is a colorant that is a carotenoid producing a yellow to orange hue. it has good tinctorial strength, fair light stability, poor oxidation stability, and good ph stability. it is insoluble in water but is available in water-dispersible, oil-dispersible, and oil- soluble forms. it has vitamin a activity. it has a natural resistance to ascorbic acid reduction in beverages and thus is used in orange- colored liquid products. it is used in margarine, oils, cheese, and puddings at levels required to produce the desired color. related colorants are canthaxanthin and beta-apo-8-carotenal.
DefinitionChEBI: A cyclic carotene obtained by dimerisation of all-trans-retinol. A strongly-coloured red-orange pigment abundant in plants and fruit and the most active and important provitamin A carotenoid.
UsesYellow coloring agent for foods.
Brand nameBetaVit (BASF); Lucaratin (BASF); Solatene (Hoffmann-LaRoche).
Safety ProfileWhen heated to decomposition it emits acrid smoke and irritating fumes.
Purification MethodsIt forms purple prisms when crystallised from *C6H6/MeOH and red rhombs from pet ether. Its solubility in hexane is 0.1% at 0o. It is oxygen sensitive and should be stored under N2 at -20o in the dark. It gives a deep blue colour with λmax at 590nm when mixed with SbCl3 in CHCl3. UV: (*C6H6) 429infl, max at 454 and 484nm. The principal peak at 454nm has 1cm 1% 2000. [Synthesis: Surmatis & Ofner J Org Chem 26 1171 1961; Milas et al. J Am Chem Soc 72 4844 1950.] β-Carotene is also purified by column chromatography (Al2O3 activity I-II). It is dissolved in pet ether/*C6H6 (10:1), applied to the column and eluted with pet ether/EtOH; the desired fraction is evaporated and the residue is recrystallised from *C6H6/MeOH (violet-red plates). [UV: Inhoffen et al. Justus Liebigs Ann Chem 570 54, 68 1950; Review: Fleming Selected Organic Synthesis (J Wiley, Lond) pp. 70-74 1973.] Alternatively it can be purified by chromatography on a magnesia column, thin layer of Kieselguhr or magnesia. Crystallise it from CS2/MeOH, Et2O/pet ether, acetone/pet ether or toluene/MeOH. Store it in the dark, under an inert atmosphere, at -20o. Recrystallise it also from 1:1 EtOH/CHCl3.
