CA2829180C — Leaf protein-lipid-soluble material complexes

USPTO Abstract

This invention describes a novel composition of matter describing a complex comprising leaf protein and a lipophilic substance(s), along with the method of producing it. Delivery of lipid-soluble materials into the body is challenging because they are generally highly insoluble in water and very subject to oxidative degradation. The inventors have found that leaf protein - the water-soluble proteins derived from plant leaves - can efficiently form a complex with lipophilic materials. This leaf protein - lipid-soluble material complex is an effective carrier of lipophilic substances. As such, the leaf protein - lipid-soluble material complex disclosed herein can be used for the delivery of lipophilic vitamins, fatty acids, caretenoids, lipophilic drugs, and other lipophilic materials. This complex can be used to deliver lipophiles in foods, nutritional and dietary supplements, topical compositions and in pharmaceutical products.
