Lychee Juice Powder Processing
The species is Litchi chinensis Sonn., the lychee, a subtropical evergreen tree of the soapberry family (Sapindaceae) native to southern China and northern Vietnam. Longan, Dimocarpus longan, and rambutan, Nephelium lappaceum, are relatives in the same family with similar translucent arils but different flavors. Buyers searching for “lychee powder” do not mean either of them, and the species name fixes the identity.
The raw material is lychee juice concentrate pressed from the white aril. The shell and seed are discarded before pressing, and the juice is concentrated and blended with maltodextrin before atomization in a spray dryer. The carrier is what makes the finished powder soluble and free-flowing, and it also dilutes the intense sweetness of the pure juice.
Lychee trees ripen their fruit within a short season, and the fruit browns quickly after harvest, so processors press soon after picking. Fresh arils are pale and translucent, which is why the powder is light yellow and not strongly colored.
Lychee cultivars differ in sweetness and seed size, and small-seeded types such as Feizixiao give more aril per fruit. The concentrate is a blend, so the powder is described by flavor character and not by cultivar name. Fully ripe fruit gives the strongest floral aroma, while fruit picked early is more acidic and less perfumed.
