Purple Sweet Potato Color

What is Purple Sweet Potato Color

Purple sweet potato is a kind of herbaceous plant of the Ipomoea genus in the Convolvulaceae family, with a purple-tinted skin and bold purple flesh. It mainly distributed in Shandong, Guangdong, Jiangsu, and other regions of China. Purple sweet potato is rich in nutrients, containing various vitamins, dietary fiber, anthocyanins, potassium, iron, zinc and other trace elements. Purple sweet potato color (PSPC) is a natural edible pigment of anthocyanins extracted and refined from the tubers, stems, and leaves of purple sweet potatoes. Its pure product presents a red to purple red powder and is a water-soluble pigment. It is also soluble in methanol, ethanol, glacial acetic acid, acetone, dilute hydrochloric acid, and dilute sodium hydroxide, but insoluble in organic solvents such as petroleum ether. Purple sweet potato color is complex in composition, with the main components being cyanogenic glycosides and methyl anthocyanin glycosides. The anthocyanins contained in it are flavonoid compounds, with C6-C3-C6 as the basic skeleton, and have the typical structure of flavonoids. The main components of PSPC are cyanidin and its methylated derivative peonidin. nd its methylated derivative peonidin (Pe, Peonidin). Due to its bright color, non-toxic and odorless properties, as well as various pharmacological and health functions such as antioxidant, anti hyperglycemic, and anti-tumor effects, PSPC is widely used in food, medicine, cosmetics, feed, dyes, and other fields.

How Purple Sweet Potato Color Works

The antioxidant activity of PSPC comes from its main component anthocyanin.
The anti hyperglycemic effect of PSPC may be due to its inhibitory effect on α-glucosidase, leading to a decrease in blood glucose concentration.
The regulatory effect of PSPC on blood pressure may come from its ability to inhibit the activity of angiotensin-converting enzyme (ACE).
The anti-cancer mechanism of PSPC mainly lies in its ability to scavenge free radicals, promote collagen, and protect proteins from the effects of proteases.

Health Benefits of Purple Sweet Potato Color

Purple Sweet Potato Color has been associated with an array of potential health benefits, such as Antioxidant, Antihyperglycemia, Regulating Blood Pressure, Antitumor and so on, here we will browes some of its important Health Benefits as below:
Antioxidant Activity
PSPC has strong antioxidant activity, and its activity is proportional to concentration. Its structure contains multiple phenolic hydroxyl groups, which can bind with proteins to prevent peroxidation, effectively eliminate lipid free radicals, cut off the chain reaction of lipid oxidation, and play a role in preventing lipid peroxidation. Moreover, PSPC have strong superoxide dismutase (SOD) activity. Oxidative reactions can lead to various diseases such as cellular oxidative damage, aging, carcinogenesis, and arteriosclerosis in the human body. Therefore, consuming PSPC with antioxidant activity can prevent the occurrence of these diseases.
Antihyperglycemia
The mouse model experiment found that the intake of purple sweet potato extract by mice resulted in a decrease in blood sugar levels, even at extremely low doses of diacylanthocyanins (one of the components of PSPC), which can lower blood sugar levels in the body. Moreover, research on the hypoglycemic effect of purple sweet potato anthocyanins (a type of anthocyanin) has found that high and medium dose groups of purple sweet potato anthocyanins can effectively inhibit postprandial blood glucose elevation. The above research conclusions all indicate that PSPC has anti hyperglycemic effects.
Regulating Blood Pressure
Research has shown that PSPC has the effect of inhibiting the activity of angiotensin-converting enzyme (ACE), which has the function of vasoconstriction and can reduce peripheral vascular resistance, thereby reducing blood pressure. In addition, anthocyanins contained in PSPC can improve blood circulation, restore and strengthen the efficacy of blood vessels, thus making blood vessels more elastic, which can not only prevent the occurrence of hypertension, but also improve atherosclerosis, heart disease, varicose veins and other cardiovascular diseases.
Antitumor
Firstly, the destruction of genetic material (DNA) by free radicals can lead to cancer. Purple sweet potato anthocyanins (i.e. PSPC) can eliminate free radicals, inhibit the spread of cancer cells, and protect more healthy cells from being eroded by cancer cells. Secondly, Research has found that collagen is the most abundant type of protein in mammals, and its degradation agents have a certain effect on inhibiting the invasion and metastasis of tumor cells. PSPC belongs to the class of anthocyanins, which not only promote collagen synthesis, but also increase collagen resistance and inhibit collagenase activity. Therefore, PSPC may also indirectly have anti-tumor functions. On the other hand, some cancers form tumors through substances that dissolve tissues and cells. These cancer cells produce lytic enzymes and proteases, and purple sweet potato anthocyanins can protect proteins from the effects of proteases. For example, the pathogenesis of breast cancer is like this, so taking purple sweet potato anthocyanins will have a good inhibitory effect on the development of breast cancer.
Other Functions
Purple sweet potato anthocyanins have certain protective effects on liver and kidney, and can prevent fatty liver, alcoholic liver, diabetes and other related diseases. Purple sweet potato anthocyanins can also improve allergic constitution, reduce inflammation, and prevent intestinal and gynecological diseases. In addition, purple sweet potato anthocyanins also have certain sun and radiation protection effects, and can improve vision and sleep.

Purple Sweet Potato Color Side Effects

PSPC is a natural pigment that is safe and non-toxic. It is used as a coloring agent in industries such as food, medicine, and feed, as well as for anti-aging skin in the cosmetics industry. It can replace synthetic pigments in cosmetics and other products, and can be used as a dye in the textile and printing industries. Therefore, purple sweet potato anthocyanins are safe and have no side effects.
