Studies on the Relationship of Maturity and Organic Acids Composition in the Flue-cured Tobacco Leaves.

황색종 잎담배 (N. tabacum L.)의 유기산과 숙도에 관한 연구

The changes of contents of organic acids in flue-cured tobacco leaves depending on stalk position and maturity viz immature, mature and overmature were studied in 1982-83. Among them, particularly, the leaves harvested at mature stage have the lowest amounts of oxalic and citric acids in smoking or cutter leaves but the acid contents has increased during the overmature. The linolenic acid content tended to be lower with increase of maturity.
