Characterization of the seed oils of some commercial cultivars of melon

Some physico-chemical characteristics, fatty acids and mineral contents of pumpkin, sweet pumpkin, melon, watermelon, paprika, tomato and cucumber seeds were determined. All seeds contained at the high levels of lipid (15.6-51.8 %) and protein (19.8-39.9 %). Among the cultivars studied, tomato seed contained the highest potassium (10542.1 mg/Kg). K, Mg, Na and P contents of samples were found high amounts than those of other elements. While acidity values of seed oils changed between 3.15 -4.24 %, peroxide values ranged between 4.72 meq/Kg to 12.5 meq/Kg. Viscosity values ranged between 25.75 mPa (tomato seed oil) to 51.2 mPa (pumpkin seed oil). While L* values of oils changed between 64.38 to 36.81, a* value ranged between 20.21 to -2.22. Linoleic and oleic acids were established as major fatty acids. While linoleic acid contents of samples ranged between 54.4 % (sweet pumpkin) to 71.6 % (paprika seed oil), oleic acid contents changed between 9.05 (paprika seed oil) to 22.9 % (sweet pumpkin and tomato seed oils).

Muskmelon seeds hold tremendous potential to be utilized as a source of bioactive compounds as these seeds are discarded as waste during melon processing. Hence, the present study aims to optimize the process parameters of a vibro-fluidized bed drying i.e., temperature (40-60°C), vibration strength (0.55-1.23), and air velocity (7-11 m/s) on bioactive compound of muskmelon seeds. Maximum retention total phenolic content (977.56 mg GAE/100 g), total antioxidant activity (47.84% DPPH reduction), oil yield (50.40%), and linoleic acid content (39.54%) were obtained at optimal conditions of 54.20°C drying temperature, 10.98 m/s air velocity, and 1.23 vibration intensity with the desirability of 0.917. The effect of temperature in comparison to air velocity and vibration strength is predominant on bioactive compounds retention. Practical applicationsMuskmelon seeds have been recognized as the proficient source of essential oils and bioactive compounds such as polyphenols and antioxidants, due to which they hold an immense potential to be utilized as a nutritional source in the food and pharmaceutical industries. From optimization of vibro-fluidized bed drying process of muskmelon seeds, it has been confirmed that intervention of vibration in fluidization could produce high-quality dried seeds. Vibro-fluidized bed dryer can be implemented as an alternative drying method to reduce drying time, processing costs, and provide a better quality of the product.
