Agro-waste: A potential source of natural colorants

“Almost 1.3 billion tons of food waste are produced per year. That’s a lot of residue. 50% of this waste is from fruits, vegetables, and root crops; all of which are rich sources of different colorant compounds. The largest fraction of this waste derives from the food industry, who could highly benefit from the reuse of their very own waste. This would limit excess money spent on waste treatment and disposal, by creating a rentable utility for this residues. The production of natural pigments from agro-waste appears to be a good solution for consumer health, business, and the environment.

Nature can provide all kinds of color. While carotenoids are responsible for the yellow and orange colors of carrots, oranges, and mangoes, chlorophyll is a pervasive green pigment present in plant leaves. Additionally, anthocyanins represent the largest group of water-soluble pigments in plants, who’s color varies from red to purple, or blue depending on the pH level of the media. These compounds are commonly found in grape and wine industry by-products. All of these natural pigments have a huge potential as food colorants.”

Kia ora! Sustainability is at the core of my soul ever since I was a kid. I always strive to finish the food on my plate and live as a minimalist. I love to cut down on waste in order to live sustainably and harmoniously with our planet. This brings me to my passion as a Food Scientist to integrate new technologies into innovative and creative solutions to meet customer demands and market trends and to optimize products and processes for quality, savings and sustainability. To these goals, I have published a Journal on my work on sustainable packaging and patented a new Antimicrobial wash. Nothing is more satisfying than working hard and smart at the workplace and playing hard outside of working hours. I enjoy rejuvenating myself through spending quality time with my two adorable kids and my awesome soul mate and getting close to nature when possible, be it gardening, tramping or going to the beach. I also love to learn about our magnificent universe and how sustainability is working in the grand scheme of things. I strongly believe that Work, Life & Balance is the key to a healthy state of mind, both physically and mentally. I look forward to making a positive difference wherever and whenever I can. Through this Blog, I hope to catalog recent Food Trends and Food Technologies that I come across so that anyone who is interested can have access to it (articles and resources). Please use these resources at your discretion. On top of that, I would also like to share related news and technologies of the future that would help mankind advance towards a Type 1 Civilization. Please feel free to contact me if you would like to share and contribute to the “Resources“. I would like to thank you in advance for dropping by. I sincerely hope that you can benefit from the recent Food Trends and Food Technologies I catalogued. Kind regards | Ngā mihi RenSun Lee
