  • Patent number: 8680301
    Abstract: There are provided foods and beverages that will suppress the absorption of dietary lipids, thereby suppressing the rise of triglyceride in blood. High-molecular weight polyphenol fractions recovered from oolong tea are added to foods or beverages as an active ingredient for inhibiting lipase activity. The foods and beverages of the present invention are safe and their inherent flavor has not been impaired; hence, they may be taken in routinely so that the lipase inhibitory action of the high-molecular weight polyphenol fractions will suppress the rise of triglyceride in blood and prevent obesity.

  • Patent number: 8309745
    Abstract: An object of the present invention is to provide a lipase activity inhibitor that shows high inhibitory activity against pancreatic lipase to suppress the absorption of meal-derived fat and/or which contributes to suppressing and preventing obesity, as well as a food or beverage that has such lipase activity inhibitor incorporated therein. Another object of the invention is to provide a lipase inhibitor of tea origin that suits most consumers' taste and which will not impair the flavor of the food or beverage when incorporated therein. Still another object of the invention is to provide a process for producing said lipase inhibitors. Further object of the invention is to provide antioxidants. To attain these objects, epigallocatechin dimers (oolong homobisflavans) or trimers are incorporated in foods or beverages. As a result, the absorption of meal-derived fat can be suppressed and, in addition, antioxidation effect is obtained.

  • Patent number: 7943578
    Abstract: It is intended to provide ACE inhibitory tripeptides which are not easily digested by digestive enzymes after being orally taken and thus have fewer tendencies to lose their ACE inhibitory activity in vivo. More specifically, 3 tripeptides having an ACE inhibitory activity and showing a hypotensive effect in an animal experiment are discovered from a thermolysin digestion product of sesame. These tripeptides respectively have amino acid sequences Leu-Ser-Ala, Val-Ile-Tyr and Leu-Val-Tyr and show an angiotensin converting enzyme inhibitory activity.
