TRANS-BETA-APO-8′-CAROTENAL

Description

trans-β-Apo-8′-carotenal is a dark purple crystal or crystalline fine powder with metallic luster. It is one of the oxidation products of carotenoids contained in citrus. It is insoluble in water and can be dispersed in hot water. It is easily soluble in chloroform, insoluble in ethanol, and slightly soluble in vegetable oil and acetone. Industrial products soluble in oils or organic solvents, with stable performance.

Chemical properties

Fine crystalline powder with dark metal- lic sheen or violet crystals.Sol in chlo- roform; sltly sol in acetone; insol in water.

The Uses of TRANS-BETA-APO-8′-CAROTENAL

β-Apo-8'-carotenal is an antioxidant β-carotene (C184250) derivative found in Cucumis melo melons and traditional Portuguese fruits and vegetables. Studies have shown that β-Apo-8'-carotenal decreased the in vivo AFB1-induced DNA SSB and the binding of AFB1 to liver DNA and increased in vitro AFB1 metabolism to aflatoxin M1, a less genotoxic metabolite.

The Uses of TRANS-BETA-APO-8′-CAROTENAL

Beta-Apo-8'-Carotenal is a colorant that is a carotenoid producing a light to dark orange hue. It has 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 is used in cheese and cheese sauces, and dressings. The maximum usage level is 33 ppm. Related colorants are beta-carotene and canthaxanthin.

The Uses of TRANS-BETA-APO-8′-CAROTENAL

β-apo-8 -carotenal is used to color juices, fruit drinks, soups, jams, jellies, and gelatin.

What are the applications of Application

trans-β-Apo-8′-carotenal is an internal standard in the detection of citrus carotenoids by reversed-phase HPLC

Definition

ChEBI: An apo carotenoid triterpenoid compound arising from oxidative degradation of the beta,beta-carotene skeleton at the 8'-position.

General Description

trans-β-Apo-8′-carotenal is a linear aldehydic carotenoid. It is naturally found in oranges, spinach, grass, tangerines and marigolds and thus, it is directly absorbed from the diet.

Biochem/physiol Actions

trans-β-Apo-8′-carotenal is commercially available as a food colorant.

Safety Profile

When heated to decomposition it emits acrid smoke and irritating fumes.

Purification Methods

Recrystallise β-apo-8'-carotenal from CHCl3/EtOH mixture or n-hexane. [Bobrowski & Das J Org Chem 91 1210 1987, Beilstein 7 III 2622, 7 IV 1782.]
