Abstract
Incorporating by-products and waste materials with nutritional and industrial potential into food formulations is an important consideration. Melon seeds, known for their nutritious compounds, are often treated as waste. This study aimed to improve the nutritional properties of cakes by adding melon seed flour (MSF), which contains high levels of ash, lipid, protein, and fiber, as a substitute for whole wheat flour and fat at concentrations of 40% and 60%. The primary fatty acid identified was linoleic acid, while the dominant amino acid in the samples was glutamic acid, followed by proline and leucine. It is noteworthy that potassium and magnesium content in MSF was about five times higher than control. The substitution of MSF did not cause a significant change in the structural properties of the cakes but led to a decrease in the firmness, springiness, and chewiness. Consumer acceptance, based on sensory evaluation, indicated that cakes with 40% MSF substitution were well-received. In conclusion, our findings demonstrate that melon seeds, previously considered waste, can serve as a good alternative source of fiber, fat, and protein in bakery products.
