In many farming towns across the country, piles of mango peels, seeds, and branches often end up rotting by the roadside. For years, these leftovers were seen only as farm waste. But scientists in Laguna are proving that what was once thrown away can now become a valuable source of wellness and beauty.
Researchers from the University of the Philippines Los Baños (UPLB) Biotech, in partnership with the Department of Agriculture–Bureau of Agricultural Research (DA-BAR), have developed two new products made from discarded parts of the popular Carabao mango. The breakthrough aims to reduce waste while supporting local industries that rely on natural and sustainable ingredients.
According to UPLB scientists, mango by-products contain high levels of polyphenols—compounds known for their antioxidant and protective properties. These findings led the team to create two high-value raw materials: PhenoFera and Diaferin.
PhenoFera is made from the mango seed kernel, which is often thrown away after processing. The extract is designed for cosmetic use and is not classified as a medical drug. Researchers say it can brighten and firm the skin, protect it from UV rays and free radicals, and help reduce irritation caused by harmful microorganisms. It also supports scalp health by reducing dandruff and improving overall hair condition, offering a plant-based option for beauty manufacturers.
Diaferin, on the other hand, is produced from Carabao mango branches. It is intended as a raw ingredient for dietary supplement makers. Early studies from UPLB show the extract may help lower blood sugar levels, providing potential support for people looking to manage glucose. Researchers note that the material is non-toxic and free from pesticide residues, making it a safer option for nutraceutical companies.
The project highlights a growing push in Philippine agriculture to convert waste into marketable products. Mango is one of the country’s top fruit exports, but nearly 40 percent of its weight becomes waste after processing. By maximizing these by-products, farmers and processors could generate extra income while reducing environmental impact.
DA-BAR officials say the initiative also strengthens local supply chains. Instead of relying on imported ingredients for cosmetics and supplements, manufacturers may soon source materials directly from Filipino research institutions and mango-growing communities.
UPLB Biotech hopes the innovation will encourage more research partnerships, especially those that transform agricultural excess into new opportunities. The team believes that with proper investment and industry adoption, PhenoFera and Diaferin could place the Philippines on the map for natural, science-based wellness ingredients.
As the country looks for more sustainable ways to support farmers and reduce waste, projects like this show how science can unlock new value from everyday produce. What was once considered trash may soon help power a growing health and beauty market—both locally and abroad.
