Chemical analysis of locally cultivated garlic and ita??s oil

摘要

This research work examines the chemical composition of Garlic cultivated in Sokoto Northwestern Nigeria using AAS analysis. It contains P, Mn and Cu (0.013) (0.0024) and (0.0012) respectively. This made Garlic a very valuable source of minerals. The results obtained indicates that garlic is rich in Calcium which is an essential mineral required for bone and teeth development, and also in the regulation of nervous excitability. The oil extracted from garlic bulbs was also characterized. The garlic bulb was discovered to have a high percentage of oil and unsaturated fatty acid (8.40%). The iodine value of the oil was also high (126.9 + 0.1), the saponification value was 192 + 0.1, which indicate that the oil can be used as food and the acid value was 41.7 + 0.1 which shows that the oil is good for human consumption.
