Longans, canned in syrup, drained

Longans are a fruit, and these figures describe the fruit only after canning in syrup and draining. They mainly provide carbohydrate, with 17g per 100g, all of which is sugars. They also contain 68mg of vitamin C and provide 276 kJ of energy per 100g. The fat content is 0.3g per 100g.

Vitamin C supports normal immune function and helps the body absorb iron from plant foods. Although the syrup has been drained away, the fruit still contains sugars, which are worth noting when considering sugar or energy intake. These values apply to the drained fruit rather than the fruit served with its syrup. Full nutrient figures are given in the tables below.
