contains anthocyanins, flavonoids, and other bioactive compounds. Anthocyanins are responsible for the blue color of the extract and are the primary pigments present in butterfly pea flower extract powder. These pigments are water-soluble and sensitive to pH and temperature changes. Flavonoids present in the extract contribute to its overall color and also have potential health benefits. Additional bioactive compounds found in butterfly pea flower extract powder include alkaloids, saponins, and tannins.
Anthocyanins are water-soluble pigments that give butterfly pea flower extract powder its blue color. They belong to the flavonoid family and contain a basic structure of flavylium cation with one or more hydroxyl groups and sugar moieties attached to it. The sugar moieties are usually glucose, galactose, or rhamnose. The structure of anthocyanins can vary depending on the type of sugar moiety attached to it.
In butterfly pea flower extract powder, the primary anthocyanin present is delphinidin-3-glucoside. This anthocyanin has a blue color and is responsible for the characteristic blue hue of butterfly pea flower extract powder. Other anthocyanins present in smaller amounts include cyanidin-3-glucoside and petunidin-3-glucoside.
Quercetin is a yellow pigment that can contribute to the greenish tint seen in some butterfly pea flower extract powders. Kaempferol is a yellow pigment that can contribute to the yellowish tint seen in some butterfly pea flower extract powders. Both quercetin and kaempferol have antioxidant and anti-inflammatory properties.
Catechin is a flavonoid that is found in green tea and also present in smaller amounts in butterfly pea flower extract powder. It contributes to the overall color of the extract and has been shown to have potential health benefits, including antioxidant and anti-cancer effects.
Additional Bioactive Compounds and Their Potential Health Benefits Butterfly pea flower extract powder also contains other bioactive compounds such as alkaloids, saponins, and tannins. Alkaloids are compounds that have physiological effects on humans and animals. Saponins are glycosides that have soap-like properties and can lower cholesterol levels. Tannins are polyphenols that have antioxidant and antimicrobial properties.
Research has shown that butterfly pea flower extract powder has potential health benefits, including antioxidant, anti-inflammatory, and anti-diabetic effects. The extract has been used in traditional medicine to treat various ailments such as fever, cough, and asthma.
In conclusion, butterfly pea flower extract powder contains anthocyanins, flavonoids, and other bioactive compounds that contribute to its color and potential health benefits. The primary anthocyanin present is delphinidin-3-glucoside, which gives the extract its blue color. The stability of anthocyanins can be affected by pH, temperature, light, and oxidation. Besides anthocyanins, butterfly pea flower extract powder contains other flavonoids such as quercetin, kaempferol, and catechin, as well as bioactive compounds such as alkaloids, saponins, and tannins.
Supercritical Fluid Extraction (SFE): Supercritical fluids, such as carbon dioxide, are used as solvents in this method. The fluid is pressurized to a supercritical state, where it exhibits both gas and liquid-like properties. When passed through the flower material, the supercritical fluid selectively extracts pigments and other compounds. SFE is known for its high extraction efficiency and minimal solvent residue in the final product.
Temperature Control: High temperatures can lead to the degradation of anthocyanins and loss of color intensity. Therefore, temperature control is crucial during extraction and subsequent processing steps. Low-temperature extraction methods, such as cold maceration or freeze-drying, are employed to minimize heat-induced degradation.
Encapsulation: Encapsulation techniques involve coating the extract particles to protect them from environmental factors that may degrade their color or bioactive compounds. Encapsulated extracts are more stable and have a prolonged shelf life compared to non-encapsulated ones.
is often used to add a natural blue color to beverages such as teas, lemonades, cocktails, and smoothies. It can also be used to create color-changing drinks when combined with ingredients like lemon or lime juice, which alter the pH and transform the blue hue to purple.
Dairy Products: Butterfly pea flower extract powder finds applications in dairy-based products like yogurt, ice cream, and milkshakes. It adds a natural blue color without the need for artificial additives.
Skincare: Butterfly pea flower extract powder is utilized in skincare products such as lotions, creams, serums, and masks. It can contribute to a visually appealing product, while its bioactive compounds offer potential antioxidant and anti-inflammatory benefits for the skin.
Cosmetic Formulations: It is used in various cosmetic products, including lipsticks, eyeshadows, blushes, and foundations, to add a natural blue color. It allows formulators to create eye-catching shades without relying solely on synthetic colorants.
Nutraceuticals: The extract powder can be used in nutraceutical formulations, including dietary supplements or functional foods. Its antioxidant and anti-inflammatory properties may contribute to overall health and wellness.
