Physicochemical and Biochemical Characterization, Total Phenolic and Energy Value from Bulbs of Different Onion (Allium cepa L.) Varieties in Senegal

The purpose of this study is to investigate the physicochemical properties of some local varieties of onion ( Allium cepa L.) and compare them with an imported variety, all collected in May 2021. Proteins, reducing sugars, lipids, and polyphenol content were estimated according to the AFNOR standar- dized methods. The determination of calcium, magnesium, iron, sodium, po- tassium and phosphorus was performed by atomic absorption spectrophoto- meter coupled with a CCD detector. The results...
