Beta-carotene > for food, dietary supplements and beverages

Carotenoids are plant pigments with a colour spectrum of yellow to orange and red. Mainly they appear in the chromoplasts of the plants. Animals are not able to synthesize carotenoids.
The carotenoids are divided into two groups: the carotenes (hydrocarbons) and the xanthophylls (oxygenated derivates of the hydrocarbons). The Xantophylls are responsible for the yellow coloration of leaves in autumn.
Naturally occurring carotenoids are completely insoluble in water and they are associated with lipids which they impart their colour for example milk fat, palm oil, tomatoes and carrots.
Carotenoids are not essential but they have a lot of important functions in the human body.
Beta-carotenes and other carotenoids have an antioxidative effect. They are able to scavenge aggressive free radicals or quench singlet oxygen. With these mechanisms cellular damages are reduced. Free radicals affect the membranes, proteins and the DNA. These damages play a role in the development of diseases like cancer or cardiovascular diseases.

Lucarotin®, Beta-Carotene

Properties

BTC’s nature identical ß-carotene is available in powder form, as emulsion and as oily dispersion (various grades).
Stability: Carotenoids are sensitive to light, heat and oxygen. Therefore the storage in a tightly sealed, lightproof packaging at a cool place is recommended. The products should be stored maximal at 25°C; shelf life is grade dependent.
Apart from the beta-Carotene dispersions, the products are stabilized by DL-alpha-Tocopherol, sodium-ascorbate or ascorbyl-palmitate.

Applications

Beta-carotene can be used for dietary supplement purposes in multivitamin tablets or beta-carotene tablets. The advantage of beta-carotene is that no upper safe level for the use of beta-carotene as provitamin A has been established in contrast to the vitamin A. Additionally an application in hard gelatine capsules is possible. For applications in soft capsules the beta-carotene dispersions are suitable as provitamin A or as colourant.
For food applications like oils, fats, margarine, butter, processed cheese, milk replacement products, ice cream, soups, sauces and egg products the beta-carotene emulsions are recommended. The dispersions can be used as yellow-orange colorant or as provitamin A. The colouring effect helps to standardize the colour of the product.
The beta-carotene products in powder form can be suggested for applications in instant powder drinks, confectionary, candied fruits, biscuits, chewing gums, soup powders, fermented milk products, pasta etc.
The different concentration of the powder products allows different colour nuances.
For beverage applications, e.g. in fruit juices, fruit beverages and lemonades, BTC is offering a cold-water-dispersible product range. The different concentrations of these products allow the colouring of yellow to orange and red.
