Abstract
In order to explore effects of Chinese herbal medicine extracts on preservation of fresh areca nuts, extracts from ginger, garlic and leaves of several Hainan tropical drug plants such as Macaranga hemsleyana Pax ＆ Hoffm, Canthium horridu Bl., Hainania trichosperma Merr., Vatica mangachapoi Blanco, together with water-soluble chitosan were used to preserve fresh areca nut. In the process, changes of apparent, weight loss, pH value, VC content and total sugar content were determined. Results showed that the Macaranga hemsleyana Pax ＆ Hoffm extracts give the best fresh preservation effects on areca nuts. With the same preservation time, fresh areca nuts rate is the highest and changes of every measured value are smallest. The fresh keeping period can be stretched from 12days to 21days under the same circumstance.
