Valorization of buffalo mozzarella cheese whey as human functional food and soil fertilizer

Abstract

Purpose: This study examines the potential of transforming buffalo mozzarella cheese whey, a significant byproduct in Mediterranean and Middle Eastern dairy production, into valuable resources. The focus is on utilizing whey as both a functional food for human consumption and a soil fertilizer, addressing waste management issues and promoting economic and environmental sustainability. Method: A multi-faceted approach was used to explore the applications of the produced edible film based on buffalo mozzarella cheese whey. The research included: An LC-MS/MS detailed assessment of the whey’s composition to identify beneficial substances, focusing on amino acids. Evaluation of whey as a soil fertilizer by analyzing its nutrient content, including nitrogen, phosphorus, calcium, sodium, and magnesium, through ICP-OES Results: The analysis revealed that buffalo mozzarella cheese whey is rich in amino acids and proteins, beneficial for human health, including cardiovascular disease prevention and immune system support. This makes whey a promising functional food ingredient. Additionally, whey contains essential nutrients for plant growth. Using whey as a soil fertilizer enhanced soil quality and reduced the need for synthetic fertilizers. Conclusion: The study confirms that buffalo mozzarella cheese whey can be effectively repurposed as both a functional food and a soil fertilizer. This dual application not only adds value to an otherwise waste product but also promotes economic growth and environmental sustainability. Implementing cheese whey in these capacities can enhance human health through nutritional benefits and support sustainable agricultural practices by improving soil fertility and reducing dependence on synthetic inputs.
