  • What is Purple Sweet Potato Powder E60?

    Purple sweet potato pigment is a natural red anthocyanin pigment extracted from the tuberous roots stems and leaves of purple sweet potato, a genus of sweet potato. It is bright and natural in color, non-toxic, and has no special smell. It has many nutritional, pharmacological, and health care functions, and is an ideal natural food coloring. Purple sweet potato pigment molecules are acylated pigment molecules with strong stability.


    Purple sweet potato red pigment is a water-soluble pigment, it belongs to the anthocyanin class of substances, from anthocyanin and sugar glycosidation reaction. Its solution liquid is bright and translucent deep red color, without the bad smell which is difficult to get rid of in the products of red pigment of kale and carotene. It can be used in the production of beverages, fruit wines, fancy colored milk and other food products.


    Purple Sweet Potato Powder E60 supplied by Greenspring Technology is a food additive made from fresh purple sweet potato tubers, which is extracted and refined with water or ethanol aqueous solution containing citric acid and other acids. It is in the form of red to purple-black liquid, powder, or granule, with no impurities visible to the naked eye. The main coloring component of purple sweet potato pigment is anthocyanin, of which the main anthocyanin ligands are cornflower and paeoniflorin. It has good heat resistance and light resistance.


    Established in 2000, Green Spring is a leading biotechnology company in China, which has been committed to researching and supplying high quality plant extracts.

    Experimental studies on the mutagenicity of Salmonella typhimurium TA98 using purple sweet potato pigments revealed that purple sweet potato pigments had strong antimutagenic effects, inhibiting the mutagenic effects caused by heterocyclic amines, 3-amino-1,4-dimethyl-5hydro-pyrido-(4,3-b)indole, 3-amino-1-methyl-5hydro-pyrido-(4,3-b)indole, and 2- amino-3-methylimidazo(4,5-f)quinoline, among others, induced mutagenic effects. It was demonstrated that especially acylated anthocyanin glycosides were more antimutagenic, whereas deacylated anthocyanin glycosides showed significantly reduced antimutagenicity.



    Anthocyanins have strong antioxidant activity and are a better scavenger of oxygen radicals. The main active group for the antioxidant action of anthocyanins is the phenolic hydroxyl group in the molecule. Purple sweet potato pigment has several phenolic hydroxyl groups in its structure, which is a hydroxyl donor and also a free radical scavenger.


    It not only binds to proteins to prevent peroxidation, but also provides protons to effectively scavenge lipid free radicals, cut off the chain reaction of lipid oxidation, and play a role in preventing lipid peroxidation. Jiang Pingping et al. conducted an in vitro antioxidant activity study on purple sweet potato anthocyanin and found that purple sweet potato anthocyanin showed considerable reducing power and hydroxyl radical scavenging ability in an in vitro model of reactive oxygen species, and it was positively proportional to the concentration. In addition, purple sweet potato pigments could resist Fe-triggered peroxidation of lecithin liposomes and inhibit erythrocyte haemolysis triggered by H2O2.


    Ling Guanting et al. have compared the juice composition of orange sweet potato (rich in β-carotene) and purple sweet potato and found that purple sweet potato has strong superoxide dismutase (SOD) activity. Comparison of the free oxygen -O2 scavenging capacity of the two juices demonstrated that purple sweet potato juice had a stronger -O2 scavenging capacity than orange sweet potato juice, which is rich in β-carotene.


    Relief of liver dysfunction

    It was found that purple sweet potato pigment could significantly alleviate various hepatic dysfunctions induced by carbon tetrachloride in rats. After giving carbon tetrachloride to rats for 5 consecutive days, the test animals suffered from acute liver dysfunction, which led to changes in various liver function indexes.


    After consuming the beverage containing purple sweet potato pigment, it could inhibit the rise of glutamic oxaloacetic transaminase (GOT) and glutamic propyltransaminase (GPT) in the serum of diseased rats. It also has a certain inhibitory ability to increase lactate dehydrogenase (LDH), sulfated barbituric acid reactive substances (TBA-Rs) in serum, TBA-Rs, and oxidized lipoproteins in the liver, thus reducing the liver injury caused by carbon tetrachloride. Some data show that the human liver function indexes are high, and in patients with a disease duration of less than 5 years, through the quantitative use of purple sweet potato extract, all liver function indexes have decreased, with an average decrease of about 20 percent.



    In a test on male mice using extracts from purple sweet potato, blood glucose concentrations in mice decreased by 16.5% after 30 min, and even the smallest dose of 10 mg/kg of diacyl anthocyanidin could reduce blood glucose levels in the body. The reason for the blood glucose-lowering effect of purple sweet potato pigments may be analyzed to be that purple sweet potato pigments cause a reduction in blood glucose concentration by producing an inhibitory effect on α-glucosidase.


    Regulate Blood Pressure

    Studies have shown that purple sweet potato pigment can inhibit the activity of angiotensin converting enzyme (ACE), which has the function of vascular end-constriction and reduces peripheral vascular resistance, thus lowering the efficacy of blood pressure. In the test of 45 volunteers taking purple sweet potato extract, 12 of them had systolic blood pressure >18.7 kPa (140 mmHg), diastolic blood pressure >12.0 kPa (90 mmHg), after drinking for 44 days, 120 ml per day, the systolic blood pressure fell by an average of 10-20 mmHg, diastolic blood pressure fell by an average of 5 mmHg, the effect of lowering blood pressure is obvious.


    In the Food Field:

    Purple sweet potato red pigment has good heat resistance and is mainly used as a red to purple coloring agent for food and added to food. Since it is a natural non-toxic product, the dosage is not limited to meet the required coloring degree.


    In Pharmaceutical:

    The addition of colours is sometimes required in the production of medicines to make them easier to identify and distinguish. Natural purple sweet potato red pigment can be used to produce coloured tablets instead of synthetic colours.


    In Cosmetics:

    Purple sweet potato red pigment has antioxidant, free radical scavenging ability, and other functions, so skin care products containing purple sweet potato red pigment can inhibit the generation of peroxides caused by oxygen free radicals due to ultraviolet irradiation, and have a certain effect on improving skin inflammation, antioxidant and so on. In addition, it can replace the synthetic pigments now used in the industry, widely used in lipstick, rouge, shampoo, and other cosmetics.
