Abstract:
Longan (Dimocarpus longan Lour.) is a non climatic subtropical plant but well adapted to
tropical areas. In Vietnam, longan is one of 12 high profitable fruit crops with a total of about
60,000-65,000 of hectares being grown throughout the country. Longan can be grown from
North to South of Vietnam with no limitation in climatic. Recently, with the support policy from
Vietnamese government and the opening of trade relation of Vietnam to other markets, longan
production in Vietnam is predicted to be increased significantly in the future. The expansion of
longan fruit from the domestic market to a significant export market has led to enhancing
research on longan post harvesting and handling for a long storage life. A number of studies on
longan fruit postharvest have been undertaken, but the research results have not been widely
published and applied. This review summarises the current longan post harvesting treatments and
chooses three treatment methods to analyse thoroughly according to the effectiveness of reducing
water loss, pericarp browning and fruit decay with minimal effect on fruit eating quality.
