Method to produce stable anthocyanin for next-generation natural colorants

A method to efficiently produce pyranoanthocyanins using cyanidin-3-derivatives and pyruvic acid or caffeic acid was established to be healthy substitute for artificial colorants and unstable alternative anthocyanins.

The Need

The demand for naturally derived food colorants has been steadily increasing due to consumer health concerns over synthetic dyes. Anthocyanins, which provide vibrant red, blue, and purple hues, are naturally derived pigments derived from fruits and vegetables. However, anthocyanins are prone to degradation under varying conditions, limiting their stability and application as food colorants. Pyranoanthocyanins, characterized by enhanced stability and resilience, offer a promising alternative, but their natural formation is time-consuming and limited in quantity. Therefore, there is a clear need for a technology that allows for the efficient synthesis of pyranoanthocyanins in larger quantities and shorter time periods.

The Technology

The disclosed technology presents innovative methods for the synthesis of pyranoanthocyanins in significantly reduced time frames compared to their natural formation. By utilizing specific reactions and temperature conditions, this technology enables the production of larger quantities of pyranoanthocyanins with improved stability and application potential as naturally derived pigments.

Commercial Applications

  • Food Colorants: Pyranoanthocyanins can be utilized as stable and naturally derived colorants in a wide range of food products, replacing synthetic dyes and meeting the increasing demand for healthier food options.
  • Beverage Industry: The technology opens opportunities for enhancing the color and stability of beverages, particularly in products such as wines, fruit juices, and soft drinks.
  • Cosmetics and Personal Care: Pyranoanthocyanins can find applications in cosmetics, including lipsticks, eyeshadows, and blushes, providing natural and stable pigmentation.
  • Textile Dyeing: The technology can be employed in the textile industry to create naturally colored fabrics, meeting the growing demand for sustainable and eco-friendly products.
  • Pharmaceuticals: Pyranoanthocyanins may have potential applications in pharmaceutical formulations, where stable and naturally derived colorants are desirable.

Benefits/Advantages

  • Time Efficiency: The technology allows for the synthesis of pyranoanthocyanins within hours, in contrast to the natural formation that can take months.
  • Increased Stability: Pyranoanthocyanins exhibit enhanced stability compared to traditional anthocyanins, making them more resilient to pH changes, water addition, and bleaching reactions.
  • Larger Quantity Production: The technology enables the generation of larger quantities of pyranoanthocyanins, making them commercially viable for various industries.
  • Healthier and Safer Option: As naturally derived colorants, pyranoanthocyanins provide a safer and healthier alternative to synthetic dyes, meeting consumer preferences for clean-label and natural products.
  • Versatility: The synthesized pyranoanthocyanins can be applied across diverse industries, offering a versatile and sustainable solution for various coloration needs.

In summary, the innovative technology for the synthesis of pyranoanthocyanins addresses the pressing commercial need for naturally derived and stable colorants, providing numerous applications across industries, along with notable benefits such as time efficiency, increased stability, and larger quantity production.
