Summary of the invention
Present invention aims to the deficiencies in the prior art, it is provided that a kind of fish oil antioxidant and preparation method thereof.The antioxidant of the present invention is less costly, can delay the oxidation deterioration of fish oil, at utmost plays its anti-aging capability, extends the shelf life of fish oil and goods thereof.
For achieving the above object, the present invention adopts the following technical scheme that
A kind of fish oil antioxidant, is made up of compound antioxidant and synergist 40 ~ 50:4 ~ 6 in mass ratio；Described compound antioxidant contains vitamin C and catechin, and wherein, the mass ratio of vitamin C and catechin is 2:1；Described synergist is the alcoholic solution of citric acid.
Described compound antioxidant is the alcoholic solution being configured to by vitamin C, catechin and dehydrated alcohol, and concentration is 5mg/mL.
The concentration of synergist is 5mg/mL.
A kind of method preparing fish oil antioxidant as above, comprises the following steps:
(1) vitamin C and catechin being mixed according to mass ratio 2:1, add dehydrated alcohol and be configured to the solution of 5mg/mL, vibrate 3min in ultrasonic oscillator, prepares compound antioxidant；
(2) citric acid dehydrated alcohol is configured to the solution of 5mg/mL, at ultrasonic oscillator vibration 2min, prepares synergist.
Step (1), step (2) the parameter of ultrasonic oscillator be: power 50W, supersonic frequency 33/40kHz, temperature 20 DEG C.
The using method of a kind of fish oil antioxidant as above: the quality according to fish oil sample, add the compound antioxidant that consumption is sample quality 0.04%-0.05% and the citric acid synergist that consumption is sample quality 0.004%-0.006%, at ultrasonic oscillator vibration 3min, fully mix；The parameter of ultrasonic oscillator is: power 50W, supersonic frequency 33/40kHz, temperature 20 DEG C.
Vitamin C is purity be 99% food stage vitamin C, catechin is purity be 98% food stage catechin, citric acid is purity be 99% food stage citric acid, dehydrated alcohol is purity be 95% food-grade anhydrous ethanol.
The beneficial effects of the present invention is:
1) present invention is by composite to vitamin C and catechin formation composite antioxidant, adds the synergistic function of citric acid so that the antioxidant of the present invention can farthest play its anti-aging capability, can delay the oxidation deterioration of fish oil；
2) the raw materials used wide material sources of the present invention, obtained antioxidant cost is low, it is easy to promote.
