2171 results about "Functional food" patented technology

A functional food is a food claimed to have an additional function (often one related to health-promotion or disease prevention) by adding new ingredients or more of existing ingredients. The term may also apply to traits purposely bred into existing edible plants, such as purple or gold potatoes having enriched anthocyanin or carotenoid contents, respectively. Functional foods may be "designed to have physiological benefits and/or reduce the risk of chronic disease beyond basic nutritional functions, and may be similar in appearance to conventional food and consumed as part of a regular diet".

Processed cheeses comprising emulsified liquid shortening compositions comprising dietary fiber gel, water and lipid

According to the present invention, fat and caloric content of processed cheeses can be reduced by the replacement of a portion fat content normally found in processed cheeses with an equal amount of emulsified liquid shortening composition comprising dietary fiber gel, water and lipid. The result is that fat and caloric content of processed cheeses can be manipulated with minimal effect on taste and texture. Furthermore, these emulsified mixtures, or “emulsified liquid shortening compositions comprising dietary fiber gel, water and lipid”, can further comprise functional foods such as high omega three and omega six oils and pure omega three and omega six fatty acids, medium chain triglyceride, beta carotene, calcium estearate, vitamin E, bioflavonoids, fagopyritrol, polyphenolic antioxidants of vegetable origin, lycopene, luteine and soluble fiber, for example Beta-Glucan derived from yeast, and other soluble fibers derived from grain, flax seed, and other vegetable and fruit fiber sources, and any combination thereof. Hence, in addition to reducing fat and caloric content of processed cheeses, further health benefits can be achieved by replacing a portion of fat with emulsified liquid shortening compositions comprising dietary fiber gel, water and lipid.
