Cholecystokinin secretion-promoting composition

Abstract

A CCK secretion-promoting substance and a use thereof are provided. This cholecystokinin secretion-promoting composition contains, as an active component, acrylic acid and/or an unsaturated aldehyde having a main chain of 4-12 carbon atoms having a double bond in at least position 2 or 4, wherein the main chain has 4-9 carbon atoms if there is a double bond only in position 2 and the main chain has 9-12 carbon atoms if there is a double bond only in position 4. This cholecystokinin secretion-promoting composition can be used as an appetite suppressant. By adding this cholecystokinin secretion-promoting composition to food, appetite-suppressing food products can be provided.

1 . A cholecystokinin secretion-promoting composition comprising, as an active component, acrylic acid and/or an unsaturated aldehyde having a main chain of 4 to 12 carbon atoms having a double bond in at least position 2 or 4, wherein the main chain has 4 to 9 carbon atoms if there is a double bond in only position 2, and the main chain has 9 to 12 carbon atoms if there is a double bond in only position 4. 
     
     
         2 . The cholecystokinin secretion-promoting composition according to  claim 1 , wherein the unsaturated aldehyde is selected from the group consisting of di-unsaturated aldehydes having 4 to 12 main-chain carbon atoms and having double bonds in positions 2 and 4, mono-unsaturated aldehydes having 4 to 9 main-chain carbon atoms and having a double bond in position 2, and mono-unsaturated aldehydes having 9 to 12 main-chain carbon atoms and having a double bond in position 4. 
     
     
         3 . The cholecystokinin secretion-promoting composition according to  claim 1 , comprising the unsaturated aldehyde having a double bond in position 2. 
     
     
         4 . The cholecystokinin secretion-promoting composition according to  claim 1 , comprising the unsaturated aldehyde having double bonds in positions 2 and 4. 
     
     
         5 . The cholecystokinin secretion-promoting composition according to  claim 1 , wherein the unsaturated aldehyde is in a trans conformation. 
     
     
         6 . The cholecystokinin secretion-promoting composition according to  claim 1 , comprising the unsaturated aldehyde having two double bonds and the unsaturated aldehyde having one double bond, or comprising the unsaturated aldehyde having two different double bonds. 
     
     
         7 . The cholecystokinin secretion-promoting composition according to  claim 6 , wherein the unsaturated aldehyde having one double bond is trans-2-octenal. 
     
     
         8 . An appetite suppressant comprising the cholecystokinin secretion-promoting composition according to  claim 1 . 
     
     
         9 . An appetite-suppressing food product comprising the cholecystokinin secretion-promoting composition according to  claim 1 .
