Item Selected physical and thermal properties of Sheri mango see kernels(Nigerian Institution of Agricultural Engineers South West Zone, 2024) Oyefeso, B. O.; Abdulsalam, A. O.; Akintola, A.Sheri mango is a widely cultivated tropical fruit with economic and nutritional significance. However, post-harvest losses due to improper drying and storage are a major concern. The quest for sustainable and efficient use of agricultural by-products is ever growing, with mango seeds being no exception, studying selected thermal and physical properties of Sheri mango seed kernel will enhance its processing. This study was therefore aimed to investigate some physical and thermal properties of Sheri mango seeds to provide a database that can serve as a guide for its processing. Sheri mango seeds used in this study were obtained from overripe mango. The seeds were then carefully cracked to avoid damage. The moisture content was determined using the oven-drying method. The properties determined include the principal diameters, geometric and arithmetic mean diameters, mass, volume, density, thermal conductivity and thermal resistivity. An average moisture content (dry basis) of 46% was obtained for the seed kernel. The Sheri mango seed kernels had major, intermediate and minor diameters within the ranges of 47.2-62.70, 11.4-15.7 and 15.1-34.6 mm, respectively while the arithmetic and geometric mean diameters ranged between 21.80 and 37.10 mm. Gravimetric properties such as the average mass, volume and density were 25.024±1.23 g, 18.52±1.52 cm3 and 1.36±0.12 g/cm3, respectively. The average thermal conductivity and thermal resistivity were 0.2786 W/m-k and 395.781 °C-cm/W, respectively. The physical properties suggest that the kernels are relatively large, which could impact their drying time and method of processing. The size also implies that the kernels have a substantial volume, which may be beneficial if the kernels are being processed for oil extraction or other value-added products. The thermal properties of Sheri mango kernels obtained indicate a moderate ability to transfer heat which can be tailored towards adjusting the processing methods to ensure optimal quality and efficiency
