尉氏青豆產于開封所屬的尉氏縣，簡稱尉青，又稱尉青豆。
       
    據明嘉靖《尉氏縣志》記載，當時尉氏就已大面積種植青豆清末到建國初，每逢中秋節過后，大批港澳商人紛紛前來采購。建國初期，年出口量達七、八百噸，遠銷港、澳、美國、西德。加拿大等30多個國家和地區，六十年代后，壓縮種植面積，中斷了出口，80年代開始擴大種植面積，使尉氏青豆重返國際市場，出口量達到歷史最高水平。1983年還曾榮獲國家外經？Q部？C發的榮譽證書。
      
    尉氏青豆豆料結實，大小勻稱，色澤青綠，表面光潤，人稱‘碧玉翠珠’。該豆特征是豆胚部外圍有一墨圈，中間有一雪白點，稱為白門。據測定，尉氏青豆含有蛋白質、脂肪和多種維生素，其蛋白質含量高達43%，居各類品種之首，是制作各種豆制的理想原料。用其制作的的豆腐、豆腐腦、腐竹等營養食品質地細膩，味首清香，而且對胃中積熱。小便不利等癥狀具有一定療效，用尉氏青豆做成的菜肴是酒席宴會中的美味佳品。
