Evaluation of the Nutrient, Phytochemical and Bacteria Flora of Local Apple (Syzygium malaccense)
Year: 2025
Type: article
Abstract: Study on the nutrient and spoilage bacteria of Syzygium malaccense was carried out in the Department of Plant Science and Biotechnology, Rivers State University. Nutrient Analysis was carried out using the method of AOAC, while the cultural technique was used for bacteria isolation. Unit for measurements for proximate composition and phytochemical analysis is in percentage (%), minerals and vitamin analysis is in mg/100g. Proximate composition analysis showed moisture, ash, lipid, fibre, carbohydrates and protein to be present. Highest (84.73%) and lowest (0.05%) values were seen for moisture and ash respectively. Mineral profiling revealed calcium, iron, magnesium, phosphorus, potassium and sodium. Although phosphorus recorded highest value (40.00%) while magnesium recorded lowest value (1.60%). Vitamin investigation showed vitamins C, A, thiamin and Chlorophile. Vitamin C recorded the highest value (43.10%) whereas Vitamin A recorded the lowest value (2.26%). Phytochemicals and anti-nutrient screening revealed glycoside, oxalate, carotenoid, polyphenol, flavonoids, and lignant to be present in S. malaccense . Enterobacter spp. was the only bacterium isolated with Total cultural heterotrophic bacteria count of 5.9 × 10-5 cfu/g. Conclusively Syzygium malaccense has vital nutrient and anti-nutrients but are prone to bacterium contamination. Therefore, fruit should be properly handled to prevent microbial contamination
