Natural colorant with anti-oxidation and anti-tumor function — purple potato extract

Purple sweet potato extract is a kind of anthocyanin pigment extracted and refined from the roots, stems and leaves of the sweet potato plant purple sweet potato. As a new type of natural pigment, it has the characteristics of bright color, non-toxic, no peculiar smell and multiple nutrition, pharmacology and health care functions. It is an ideal natural food pigment. In addition to being a natural colorant, it also has certain physiological functions, such as anti-mutagenicity, anti-oxidation, and anti-tumor functions.

1. Antimutagenicity

The experimental study on the mutation of Salmonella using purple sweet potato pigment found that purple sweet potato pigment has a strong anti-mutation effect;

2. Anti-oxidation and scavenging free radicals

Lipid peroxidation and free radical reaction of active oxygen can cause many diseases such as oxidative damage, aging, carcinogenesis and arteriosclerosis in human cells, which are all related to the oxidation reaction in the body. By eating foods with antioxidant capacity, you can prevent a variety of diseases.

Anthocyanin has strong antioxidant activity and is a good oxygen radical scavenger.

4. Relieve liver dysfunction

Through experiments on rats, it was found that through quantitative use of purple sweet potato extract, various liver function indexes have decreased, with an average decrease of about 20%.

5. Anti-hyperglycemia

Experiments on male mice with purple sweet potato extracts have been found to reduce blood glucose levels in the body. Purple sweet potato pigment has the effect of lowering blood sugar.

6. Regulate blood pressure

Studies have shown that purple sweet potato pigment has the activity of inhibiting angiotensin converting enzyme (ACE). ACE has the function of terminal contraction of blood vessels and reduces the peripheral resistance of blood vessels, thereby reducing blood pressure.

7. Anti-tumor

Collagen degradation agents may play a role in inhibiting the invasion and metastasis of tumor cells, so it is speculated that it can inhibit the invasion and metastasis of tumor cells and have anti-tumor functions.
