Abstract
Functional foods have gained a great deal of attraction since people started to consume healthier foods. There were numerous synthetic food colorants employing in preparation of food products. However, nowadays using these kinds of food colorants has been restricted in many contraries. Consequently, the consumption of natural food colorants has been increased worldwide. Most of these natural food colorants are bioactive with health benefits and sensitive. Therefore, incorporation of them into food products is an important issue. Lipid nanoparticles (SLN and NLC), have joined the advantages of emulsions, liposomes and polymeric nanoparticles. NLC, as a new generation of lipid nanoparticles, has overcome the disadvantage of SLN by mixing solid lipids with liquid lipids. Hence, they have found various pharmaceutical applications. Carotenoids are widespread natural pigments which are important sources of yellow, orange and red colorants for food industries. They may reduce the risk of certain types of cancer and cardiovascular diseases. But, they are usually water insoluble and unstable. Lipid nanoparticles were utilized to protect the carotenoids from degradation during the production and storage and to incorporation of water insoluble carotenoids into water based foods. Ultra small carotenoid loaded lipid nanoparticles were produced with high stability. Lipid nanoparticles can be employed as an appropriate carrier for bioactive food colorants and improve the bioavailability of these compounds.
