Fermented ginger can improve nutrient absorption and support a normal inflammatory response.
The content of gingerol in fermented ginger was higher, including 6-gingerol, 8-gingerol, 10-gingerol and 12-gingerol, among which 6-gingerol had the highest content.
Gingerol has the functions of lowering blood lipids, strengthening the heart, anti-oxidation, anti-aging, anti-tumor, anti-ulcer, anti-coagulation, anti-inflammatory and analgesic, anti-emetic, anti-dizziness, deworming, sterilization, and antiseptic. Edible flavors and condiments, cosmetics, functional foods and green pesticides have great potential application value.
Functional properties of gingerol
(1) The antioxidant effect of gingerol.
The structural basis for the functional activity of gingerol lies in the presence of guaiacol and β-hydroxyketone structures in the molecule. Gingerol has strong antioxidant activity, its antioxidant capacity is higher than that of butylated hydroxyanisole, dibutylhydroxytoluene, vitamin C, vitamin E, 6-gingerol, 8-gingerol and 10-gingerol It can effectively scavenge DPPH, superoxide and hydroxyl radicals, and the antioxidant capacity of 10-gingerol is better than the other two gingerols.
(2) Antibacterial effect of gingerol.
Gingerol has a certain inhibitory effect on Gram-negative bacteria, Gram-positive bacteria, yeast and fungi. Experiments show that gingerol at 8.0-22.0 μg/mL can effectively inhibit Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Saccharomyces cerevisiae and Aspergillus niger. 10-gingerol and 12-gingerol can effectively inhibit oral pathogenic bacteria at 4~20 μg/mL, which lays a theoretical foundation for the application of gingerol in daily oral care.
(3) Gingerol's cardiotonic, hypolipidemic, hypoglycemic and hypotensive effects.
6-gingerol, 8-gingerol and 10-gingerol can enhance myocardial contractility by activating skeletal sarcoplasmic endoplasmic reticulum-related enzymes and increasing sarcoplasmic reticulum uptake by cardiomyocytes. decreases as the number of carbon atoms increases. 6-gingerol can significantly reduce the levels of blood sugar, triglycerides, cholesterol, free fatty acids and low-density lipoprotein cholesterol in the tested diabetic mice, and can also effectively prevent the oxidative toxicity and oxidative toxicity caused by the heavy metal element arsenic. Regulate insulin. high blood sugar. Gingerol has the effect of dilating blood vessels, and the antihypertensive effect of hypertensive animals is proportional to the dose of gingerol.
