This project cooperated with the Georgia Biotech. Co., aims at investigating the optimal sowing and harvesting time, and the processing methods for making buckwheat tea bags and tablets. The results of autumn crop 2001, indicated that the optimal sowing date was on 5th November and harvest 45-55 days after sowing with the cultivar ‘Charng Lu Chiu’. The optimal drying process for making tablets is sun-dried after harvest and subsequently oven-dried for 24h. For making tablets, the plant materials were milled, boiled, filtrated and concentrated into fine powder subsequently and pressed into tablets finally. Following the process, the tablets would contain the highest amount of rutin and quercetin, which have been confirmed beneficial to human health. The buckwheat tea-bag product is massively produced and commericialized by the Georgia Biotech. Co.
