Abstract
Background: Flaxseed is becoming an increasingly widely used food ingredient. The rising interest of the food industry in this nutraceutical is primarily because of functional nutrients, such as alpha-linolenic acid and lignans, which have health benefits due to their lipid-lowering properties.
Objective: The objective of this study was to provide an overview of the patenting of flaxseed products with cholesterol-lowering effects. Method:Patent applications filed by country of origin were retrieved from the Derwent Innovations Index®database. Results: A total of 307 patent documents were identified, of which 184 claim the use of flaxseed or parts of the flax plant in the product formulation, for their lipid-lowering effect when consumed by humans. A few of the patent applications contain claims for new products based on flaxseed in isolation, including the preparation of foods designed to inhibit the production of cholesterol. Most of the claims were for flaxseed in the form of oil and in association with other lipid-lowering compounds, mainly for the food industry, in the form of dietary supplements or baked products designed to raise their high-density lipoprotein content, and for treating heart problems. China and the United States are the leading countries of flax-related applications. Conclusion: These results may have important implications for the production of functional food products that meet specific societal demands.Keywords: Cholesterol, flaxseed, flaxseed products, functional food, linseed, nutraceuticals, patent.
