Senxin developed a new Phalaenopsis blue pigment, which was approved by the FDA for use in food

Recently, the U.S. Food and Drug Administration (FDA) approved the company's Phalaenopsis extract to be used as a coloring matter and added to food after receiving a related application from a coloring company under Sensient.


Senxin Technology is a well-known manufacturer of flavors, fragrances and food additives in the United States and even the world. It is reported that the FDA approved Senxin Technology to apply its Phalaenopsis extract to a series of food and beverages, including alcoholic and non-alcoholic beverages, liquid coffee creamer, ice cream, frozen milk desserts, soft and hard candies, yogurt and bubble gum .


Senxin said that the development of its Phalaenopsis extract took more than 10 years and is the first natural plant-derived blue pigment approved by the FDA. Senxin said that this pigment has "excellent thermal stability and water solubility", and can produce different shades from bright blue, deep purple to natural green depending on the pH of the product. When used in products with a pH higher than 3.8, it can form a "bright denim blue"; when used in food and beverages with low pH, such as sports drinks, it can form a deep purple.


Senxin introduced that Phalaenopsis is a plant native to the equatorial region of Asia and is often used to make decaffeinated scented tea. Restaurant chefs and food and beverage manufacturers also use it to add bright colors to their dishes. The company said that in order for it to be approved for use as a pigment in the United States, they are working hard to ultrafiltration and concentration, and strive to meet FDA requirements.


Mike Geraghty, President of Senxin Pigment Co., Ltd. said: "Although Phalaenopsis is relatively ubiquitous in parts of Southeast Asia, we have found that varieties grown in large areas for other purposes do not perfectly meet the standards. Natural pigment manufacturing needs. Through the company’s "From Seed to Shelf" agronomy program, we invested funds to cultivate flowers with higher pigment content, so as to produce more stable, safer and cleaner for modern food and beverage manufacturers. Blue pigment."


Senxin described the development process of Phalaenopsis blue pigment in the application, that is, adding insecticide-free dried Phalaenopsis petals to the softened water, and after the ultrafiltration process, the liquid is concentrated and disinfected. The final product contains 42%-62% water, and the main coloring component is anthocyanin.


The food ingredient industry has long faced the problem of developing natural blue pigments. Since the end product may be exposed to a series of environmental conditions and has a shelf life requirement, the added pigments need to ensure stability and freshness, which hinders the development of natural blue pigments. In this context, the speed of innovation has accelerated recently. Among the promising natural blue pigments, Senxin's Phalaenopsis extract is the latest research and development product.


World-class food processor Mars Wrigley asserts that a pigment in red cabbage can be used to make a long-lasting, stable natural edible blue pigment. Spirulina, a single-celled algae, also shows promise. In 2019, the natural pigment company GNT launched a series of high-strength blue powders derived from spirulina for the first time, and Senxin also developed pigments derived from algae a few years ago. There are also some natural blue pigments that "grow on trees." Wild Flavors and Specialty Ingredients, a subsidiary of ADM, a global agricultural product processing company, has obtained a patent for a blue pigment derived from tropical fruit huito, which is called huito blue.
