Function of purple sweet potato extract
Nowadays, research reports on purple sweet potato emerge in an endless stream, mostly focusing on the study of its extract, purple sweet potato extract functions are:
1, antioxidant, purple sweet potato contains very rich antioxidant substances, especially anthocyanin content is several times or even ten times of the ordinary sweet potato, it has a significant effect in scavenging free radicals, its antioxidant capacity and purple sweet potato extract concentration is proportional.
2. Protect the liver and protect the liver, purple potato extract can inhibit the activities of glutamate-oxalacetic acid transaminase and glutamate-pyroglucosamine transaminase, and also has an inhibitory effect on oxidized lipoprotein and liver vulcanized barbiturate reactants, so as to enhance the function of the liver and inhibit the occurrence of liver inflammation.
3. Lowering blood glucose. Studies have pointed out that anthocyanins in purple sweet potato extract can regulate blood glucose and dyslipidemia, and diacyl anthocyanins in purple sweet potato extract have significant hypoglycemic effects, and their blood glucose concentration was reduced by 16% in animal tests.
4, antibacterial effect, purple potato extract can be combined with proteins or enzymes in cells, so as to show inhibitory effect on bacteria, which has significant inhibitory effect on Staphylococcus aureus, pyomonas aeruginosa, Escherichia coli and other pathogenic bacteria.
Advantages of purple potato extract
According to reports, purple potato contains about 0.51mg/g of anthocyanins, while the content of blueberry is about 1.29mg/g of anthocyanins. Although its content is far less than that of blueberry, its price is low. The cost of extracting the same amount of products is only one sixth of that of blueberry. Can also make full use of purple potato starch processing byproducts, its value conversion rate is higher, the application cost is lower.
Application of purple sweet potato extract
Different countries have different regulations on extracts, and different sources of extracts have different application scenarios, including food additives, health food raw materials, flavors, pharmaceutical raw materials, etc. For purple sweet potato extract, in addition to the above common directions, purple sweet potato extract as a functional factor in the application of common food research is also increasing, not only increase the product functional attributes, but also help for product stability.
