Food processing waste is a potential resource of a variety of bioactive compounds. Carrot peel is a good example of phytonutrient-rich agroindustrial byproducts generated from the processing of carrots. The conventional methods for the extraction of phytonutrients typically involve large volume of organic solvents, complex procedures and expensive equipment.

- - Agro-industrial waste, like tomato pomace, is a valuable source of bioactive compounds such as carotenoids and pectin, but traditional extraction methods are inefficient and resource-intensive.
- - A new extraction method using carotenoid-pectin complexation in water was developed, yielding up to 9.43 mg of carotenoids per 100 g of tomato pomace, with a high purity of 92%.
- - This innovative method not only provides comparable extraction efficiency and antioxidant capacity to conventional methods but also presents an eco-friendly option for utilizing agro waste products.
