First, the health-care food composition of the present embodiment is added into distilled water to appropriate concentration, health-care food composition is entered Row determination oxidative, it is specific as follows:
(1) hydroxyl radical free radical ability measure is removed
Sample cell:2mL Phen solution is taken, phosphate solution (pH7.4) 3mL is added thereto, is added after mixing FeSO4Solution 1mL, 1.5mL composition solutions are added after fully mixing, add ultra-pure water afterwards, finally add 2mL H2O2Mixing is equal It is even, after insulation reaction 1h, numerical value is determined under 536nm.
Blank tube:Composition solution and H are replaced with ultra-pure water2O2Solution, assay method are same as above.
Damage pipe:Composition solution is replaced with ultra-pure water, assay method is same as above, and is set 3 repetitions and averaged.
Result of the test:
Stronger to the Scavenging activity of hydroxyl radical free radical, when concentration is 15mg/mL, the clearance rate of hydroxyl radical free radical reaches 95.23%, higher than the clearance rate (92.89%) of Vc under equal experiment condition.
(2) superoxide anion ability measure is removed
4mL composition solutions are taken, add 5mL Tris-HCl buffer solutions (pH8.2) thereto, are mixed after being protected in water-bath Warm 15min, 0.15mL pyrogallol solution is then added, its reaction is terminated with 0.8mLHCl solution afterwards, under 335nm wavelength Measure.Wherein by the use of ultra-pure water as control, by the use of Tris buffer solutions as blank, it is repeated 3 times experiment and averages.
Result of the test:
Stronger to the Scavenging activity of superoxide anion, when concentration is 15mg/mL, the clearance rate of superoxide anion reaches 87.35%, higher than the clearance rate (85.13%) of Vc under equal experiment condition.
(3) H is removed2O2The measure of ability
Take pH7.4 phosphate buffers that composition solution is diluted into experimental concentration, equally take phosphate buffer by H2O2 Solution is diluted to 40mmol/L.The composition solution 3mL after dilution is taken afterwards, with 0.6mL H2O2Solution fully mixes, after standing Its light absorption value is determined under 230nm wavelength, wherein with H2O2The light absorption value of solution itself is repeated 3 times experiment and is averaged as control Value.
Result of the test:
To H2O2Scavenging activity it is stronger, when concentration is 15mg/mL, H2O2Clearance rate reach 90.38%, with equal reality Vc clearance rate (90.76%) is suitable under the conditions of testing.
2nd, food safety evaluation is carried out to the present embodiment health food, it is specific as follows:
(1) test material
Sample:The present embodiment is had after the health food of anti-oxidation function is dissolved in distilled water, be configured to needed for it is dense Degree, 4 DEG C of preservations, heating water bath is to 37 DEG C before administration.
Animal subject:The ICR Strains of Mouse of health, 18~22g of body weight, male and female half and half.
(2) test method
Before and after feeding the present embodiment health food, experiment mice male and female divide cage, and full-valence pellet feed is fed, free water, 20~25 DEG C of room temperature, laboratory relative humidity are 50%~70%.
Mouse is randomly divided into 2 groups:(1) the present embodiment health food group;(2) blank control group.Fasting 12h before experiment, With 0.5g/mL the present embodiment health food, the gastric infusion 0.5mL/10g once a day;Blank control group gives equivalent Distilled water.Continuous Observation 14d is not dead small situations such as record test mice behavior, activity, food ration, body weight, excrement, death Mouse performs an autopsy on sb. after 14d.
Result of the test:
This experiment feeds mouse with maximum dosage-feeding, and the administration same day sees that mouse hair color is smooth, and activity, food ration, excrement are equal Normally, second day activity, food ration, body weight increase, excrement etc. are normal, the no significant difference compared with blank control group, and two Performed an autopsy on sb. put to death without dead and other abnormal generations, two groups in all simultaneously after, each main organs (heart, liver, spleen, lung, kidney) warp Visually observe no abnormality seen change, the no significant difference compared with blank control group.
Toxicity assessment:
The maximum dosage-feeding result of the test that the present invention has the health food gastric infusion of anti-oxidation function shows, used small Without obvious toxic reaction after mouse administration, without death in 2 weeks.Therefore the health food edible safety of the present invention.
