Agriculture sector plays a pivotal role in Nigeria's economic development, necessitating the grading of agricultural products based on size. Grading of date seeds are essential for proper handling, processing, storage, and value addition. To develop appropriate processing technologies, understanding the engineering properties of agricultural products is crucial. Hence, studying the engineering properties of date seeds is imperative. The physical, chemical, and microbiological characteristics of red and yellow date seed variants were ascertained in this study. Physical properties examined encompassed mass, length, width, thickness, volume, geometric mean diameter, arithmetic mean diameter, sphericity, and surface area. For the yellow date seed variety, its mass ranged from 0.85g to 3.01g, while for the red variety it mass ranged from 0.99g to 1.76g. Similarly, length, width, and thickness exhibited varying ranges for both varieties. The arithmetic and geometric mean diameters also displayed distinct ranges for each variety. Chemical properties such as moisture, ash, protein, carbohydrate, fat, and crude fibre content were assessed. Moisture content was found to be 4.87% and 5.76% for the red and yellow varieties, respectively. The red and yellow types had an ash level of 1.05% and 1.08%, respectively. Protein, carbohydrate, fat, and crude fibre content also varied between the two varieties. Moreover, the microbial properties analysis revealed that the study of ethanol in dates could serve as a natural food preservation method, potentially yielding health-protective compounds with antimicrobial activity.
