Description:
The oily vitamin blends vary in viscosity, and in colour from yellow to orange, depending on their composition. Blends that contain beta-carotene tend towards orange.

Vitamin A crystallizes out of the mixture if it is stored at low temperatures, but the crystals redissolve by heating slowly to about 40°C. This is also the optimum temperatures for processing.

Composition:
We manufacture blends of the above vitamins in the proportions required by the customer. Vegetable oils are used as carrier. The standard oil used is sun flower oil, though others can be used on request.

Solubility:
Soluble in a wide range of organic solvents. Insoluble in water. The solvents should contain no peroxides.

Assay: min.100% of the declared content of each vitamin

Monographs:
All the vitamins used comply with the relevant monographs in one or more of the main internat pharmacopoeias, i.e. USP, Ph, Eur. and FCC.

Stabilization/Stability:
The oily vitamin blends are available stabilized with DL-a-tocopherol (E307) or butylhydroxytoluene (BHT, E321), or unstabilized. The products are stable for up to 24 months if they are stored in the unopened original containers at 5°C.

Applications:
Particularly suitable for fortifying food products with a high fat content, e.g. margarine, spreads, edible oils, mayonnaise, salad dressings, cheese spreads etc.
