Longan is a tropical fruit that is suitable for consumption. The longan tree belongs to the Sapindaceae family, which encompasses various other fruit-bearing plants. The longan fruit is a little, spherical fruit with a pale white pulp and a yellow-brown outer covering, which is typically found in pendant clusters. The fruit exhibits a slight sweetness and juiciness, displaying resemblances to the lychee fruit. The longan fruit has a somewhat drier sweetness and a musky flavor profile, whereas lychees possess a greater juiciness, aromatic qualities, and a little more pronounced sour sweetness. The fruit known as longan, scientifically referred to as Dimocarpus longan, is commonly referred to as dragon’s eye fruit due to its characteristic appearance. This fruit has a pale white flesh, encasing a little brown seed positioned centrally within its structure.
During the maturation process, the exocarp of the fruit transforms, resulting in the development of a rigid outer covering that may be effortlessly removed when consuming it. It is advisable to extract the seed before consuming the fruit. The increasing recognition of the seeds of the fruit as a nutritious dietary option can be attributed to their rich content of gallic acid (GA) and ellagic acid (EA), both of which are phenolic chemicals obtained from plants. The consumption of longan fruit is observed in various forms, including fresh, dried, and tinned. The fruit is additionally employed for therapeutic applications; it has been utilized in traditional Asian medicine due to its nutritious properties. However, longan is not merely a typical tropical fruit originating from Southeast Asia; it has been utilized for several years in the realm of traditional medicine.
