Example 7 (Sample and Test Method) As a sample, a dried product of Tailing ghetto and squeezed juice of ghetto stalk was used. 3-t-Buty1-, a synthetic antioxidant currently used in foods for comparison
The antioxidant property of 4-hydroxyanisole (BHA) was measured.

The antioxidative property was measured by a method utilizing the property that β-carotene is discolored in the presence of linoleic acid oxide. That is, to a 200 ml Erlenmeyer flask, 0.5 ml of a 0.1% β-carotene chloroform solution and 0.5 ml of a 10% chloroform solution of linoleic acid were added, 20% Tween 40 solution was added and mixed sufficiently, and nitrogen gas was blown to volatilize the chloroform. , 100 ml of distilled water was added to add linoleic acid-β
-Carotene solution was prepared.

To 45 ml of this solution was added 4 ml of 0.2 molar phosphoric acid buffer solution (pH 6.8), the mixture was gently spread and 4.9 ml was placed in a test tube.
Aliquot each, add 100 μl of the test solution, and immediately add 50 ° C.
The sample was transferred to a constant temperature bath of No. 2 and the change in the absorbance of OD470 for 0 to 60 minutes was measured to display the antioxidant property.

(Sample and Test Method) As can be seen from the results shown in FIG. 7, in the control linoleic acid (-Δ-), the amount of oxide increased with the passage of time, β-carotene was discolored, and the absorbance value rapidly increased. However, when the dried product of ghetto and Tailing ghetto stalk was added, its absorbance hardly changed or showed a gradual decrease.

Comparing the dried stalk juices of ghetto (-●-) and tailing ghetto (-■-), 1% concentration showed almost no change compared to the initial absorbance at the start of heating, and both ghettos were Suppressed the oxidation of linoleic acid by 100%. At a low concentration of 0.2%, the decrease rate of Tyringia ghetto (-○-) is slow even at the same concentration.
From □-), it is understood that Tyring ghetto shows a strong antioxidant power.

Further, when compared with the antioxidant BHA (-⋄-), BHA at a concentration of 1 mg / 100 ml shows a decrease tendency almost similar to that of 0.2% ghetto, so that 0.2% ghetto stalk juice dried product is 1 mg / It has an antioxidant power equivalent to that of 100 ml of BHA, and the 0.2% Tylinget stalk dried stalk juice has a lower reduction rate than BHA, which indicates that it has a stronger antioxidant power than BHA.
