Food processing by-products are normally used as animal feeds with low value or directly disposed of in landfills which could cause severe environmental damages in the long run. These waste products are untapped sources for potential valuable food ingredients such as antioxidants and pharmaceutical compounds. In line with our visions for developing energy efficient and sustainable food processing technology, we are actively researching on physiochemical and bioactive properties of the food processing waste products and developing novel methods to extract the valuable materials from the by-products.
