The rising demand for avocado fruit from its recognized nutritional value which has significant positive impacts on human health. The current investigation was undertaken to analyze the nutritional values, chemical composition, fatty acids profile and minerals content of avocado fruit cultivars cultivated in Bangladesh. The findings revealed varying levels of key components across different cultivars where cultivar PA-Joy002 had a higher content of dry matter 30.92%, total soluble solids 7.31o Brix, oil 18.57%, crude protein 4.44%, carbohydrate 4.14%, and fibre 4.50% than the BARI released var. BARI Avocado-1. The major fatty acids profile of pulp-oil of avocado cultivar PA-Joy002 revealed that the oil contained high amount of oleic acid 35.99%, linoleic acid 25.02%, palmitic acid 28.25%, palmitoleic acid 9.85%, and lenolenic acid 2.30%, respectively. Moreover, cultivar PA-Joy002 contained significantly higher amount of unsaturated (UFAs, 71.35 %) fatty acids than saturated (SFAs, 32.58 %) fatty acids, and the ratio of UFAs to SFAs was also higher 2.19. The results also indicated that 100 g of dry pulp of avocado sample contains calcium 861.19 mg, potassium 1374.63 mg, magnesium 503.02 mg, phosphorus 341.14 mg, sodium 7.10 mg, iron 9.30 mg, and zinc 3.72 mg of the same cultivar. Findings of this study indicated that cultivar PA-Joy002 was nutritionally rich and promising to use as a functional food due to their high content of nutritional elements, essential fatty acids and minerals, and versatile applications of its pulp.
