Purple Sweet Potato Pigment/Color Powder

Product Description

What is Purple Sweet Potato Color?

Purple sweet potato color is a natural red pigment extracted from the tuberous roots stems of the purple sweet potato. Classified as an anthocyanin, it is formed through the glycosylation of anthocyanidins with sugars.Its primary components are acylated cyanidin glycosides and acylated peonidin glycosides.

It appears as a red to purplish-red powder that is readily soluble in water and ethanol. Its color shifts significantly with pH levels: appearing red in acidic conditions, and blue in both neutral and alkaline environments.

Due to the presence of acyl groups and polyphenolic hydroxyl structures within its molecules, the pigment exhibits excellent heat and light stability as well as antioxidant capacity, remaining particularly stable under acidic conditions.

As a natural food colorant, it is widely used in the processing of beverages, candies, and jellies, and its applications have expanded into the pharmaceutical and skincare industries.

Purple Sweet Potato Color Specification

Purple Sweet Potato Color Stability

• Thermal Stability: Purple sweet potato pigment exhibits good thermal stability; however, its stability decreases under conditions of high temperature and prolonged heating.
• Photostability: Purple sweet potato pigment demonstrates good photostability, surpassing that of the red pigments found in plants such as purple grapes, perilla, and black rice.
• pH Sensitivity: Purple sweet potato pigment is highly sensitive to pH. As the pH rises, the anthocyanins transform from red flavylium cations into colorless carbinol pseudobases. The pigment displays a stable red color at pH ≤ 5, whereas at pH > 5, the color shifts from red to purple and subsequently to blue.

Purple Sweet Potato Color Application

• Food Industry

As a natural pigment, purple sweet potato pigment is widely used in the food industry. It serves as a coloring agent for products such as candies, chocolates, and ice cream, enhancing their visual appeal. Additionally, it can be incorporated into beverages—such as purple sweet potato juice and wine—to impart natural color and aroma.

• Cosmetics

Purple sweet potato pigment also finds extensive application in the cosmetics industry. Thanks to its antioxidant and anti-inflammatory properties, it can be added to products like face creams, facial masks, and lipsticks to boost their efficacy. Furthermore, its vibrant hue adds a unique visual appeal to cosmetic products.

• Pharmaceuticals

Pharmaceutical manufacturing often requires the addition of coloring agents to make medications easier to identify and distinguish. Common pharmaceutical colorants include agents like Ponceau 4R, Carmoisine, and Indigo; however, these are synthetic pigments that may pose health risks. Natural purple sweet potato pigment offers a safe alternative for coloring tablets, facilitating product identification while avoiding the potential side effects associated with long-term exposure to synthetic pigments.

• Other 

Beyond food and cosmetics, purple sweet potato pigment is utilized in sectors such as animal feed, textiles, and printing and dyeing. In the animal feed industry, it serves as a colorant that can stimulate appetite and promote growth in livestock. In the textile and printing/dyeing industries, it acts as a natural dye, imparting color to fabrics and paper products.
