In　order　to　explore　quality　evaluation　methods　for　Chinese　coffee　beans　for　freshly　ground　coffee　and　instant　coffee　and　to　select　evaluation　indicators,　the　major　quality　indicators　were　selected　from　the　basic　quality　indicators　through　the　Delphi　evaluation　method　and　sequence　relationship　analysis　to　construct　a　quality　index　system.　Then　the　differences　in　the　major　quality　indicators　of　53　coffee　bean　samples　from　different　production　areas　in　Yunnan　and　Hainan　provinces　were　determined,　the　characteristic　quality　indicators　of　coffee　beans　for　different　purposes　were　selected　by　correlation　analysis,　principal　component　analysis　(PCA)　and　cluster　analysis,　and　stepwise　multiple　linear　regression　analysis　was　conducted　based　on　the　comprehensive　scores　of　the　principal　components　of　the　samples.　Finally,　grain　size,　taste,　aroma　and　carbohydrate　content　were　selected　as　the　characteristic　quality　indicators　of　instant　coffee　and　grain　size,　taste,　aroma　and　caffeine　content　as　the　characteristic　quality　indicators　of　freshly　ground　coffee.　It　is　determined　that　the　major　varieties　suitable　for　instant　coffee　are　Catimor　and　Typica,　and　the　major　production　area　is　Yunnan　province.　The　major　variety　suitable　for　freshly　ground　coffee　is　Catimor,　and　the　major　production　area　is　Yunnan　province.　©　2024　Chinese　Chamber　of　Commerce.　All　rights　reserved.
