PURPOSE:To obtain the subject food having suppressive activity against absorption of fat from bowels and preventive function against obesity due to excessive intake of fat by compounding a high fat main component with purified gymnema acid derived from acidic precipitate of an extract component obtained from Gymnema sylvestre. CONSTITUTION:Dried leaves of gymnema sylvestre is immersed in hot water of about 60 deg.C for >=5hr and mildly centrifuged with rotation of 1200-1300rpm. The supernatant is dried by lyophillization to obtain powdery extract component. This is dissolved in water. Acidic precipitate is obtained by adjusting the pH of the solution to 3 and purified gymnema acid (i-GA) is obtained from the precipitate. The i-GA is further washed with water and extracted with ethanol and the extract is concentrated under reduced pressure. The concentrated extract is centrifuged after adding acetone and a purified product (p-GA) is precipitated from the supernatant. Thereafter, the objective high fat food having antiobestic function is obtained by compounding a high fat food containing a high fat main component with the purified gymnema acid (p-GA). |
