Fresh Onions - Red

Country of Origin: Pakistan

The edible onion belongs to the lily family (Liliaceae) and comes originally from Central Asia.The onion (bulb) is composed of a highly compressed basal plate, which gives rise to the roots, and the main shoot apex, around which the thickened onion scale leaves are arranged. These end in the onion neck, from which the above-ground shoot or peduncle emerges. The outermost scale leaves are dry and protect the onion from external influences.The ripening process starts when the onion bulb proper forms. Bulb formation is determined by day length and varies with the variety of onion.Postharvest, the onion undergoes a post-ripening process. This post-ripening does not consist merely of the purely sical process of drying of the onions but also of the attainment of a certain siological stage known as sprout or growth dormancy. During this process, the roots, peduncle and outermost scale leaves dry; the latter change color and lie tightly around the onion neck, providing protection against evaporation and attack from microorganisms. This process is further assisted by subsequent post-drying.
