Detailed Description

The technical solution of the present invention is further illustrated and described by the following detailed description.

Examples

(1) Preparing a banana peel extract:

a. drying and crushing 1kg of banana peel, adding 2L of 20% ethanol aqueous solution, leaching for 20 minutes at 50 ℃ under hot reflux, filtering and concentrating to obtain a leaching solution;

b. extracting the leaching liquor with diethyl ether to obtain extract liquor;

c. performing column chromatography on the extract by using a polyethylene glycol 20000 column, and eluting by using 10% ethanol water solution to obtain a first-stage eluent;

d. performing chromatography on the first-stage eluent by using 200-mesh polyamide powder as an adsorbent, and then eluting by using a 1% acetic acid aqueous solution to obtain a second-stage eluent;

e. recrystallizing the second-stage eluent twice with ethanol, and drying to obtain the banana peel extract;

(2) mixing 95% of banana peel extract of the banana peel extract, 0.3% of sodium glutamate, 0.02% of ferrous sulfate, 0.02% of calcium lactate, 0.6% of vitamin A, 0.3% of vitamin E, 3% of vitamin C, 0.2% of vitamin D and 60.02% of vitamin B in parts by weight, uniformly stirring, and drying to obtain the banana peel antioxidant additive. Vitamin E in the antioxidant additive is an important antioxidant and membrane stabilizer in cell membranes, maintains the normal mechanism and metabolism of muscle tissues, and plays an important role in energy supply and calcium ion uptake and release particularly during muscle contraction; vitamin C can significantly reduce exercise-induced oxidative stress. The antioxidant additive is natural in material, free of toxic and side effects, capable of resisting coagulation, reducing blood fat, enhancing cellular immunity and resisting tumors, good in antioxidant effect and wide in application range.
