河南自古就是小麥的主要產地，《詩經》上記載有“我行其野，芃芃其麥。”類似這些記載尚有很多，都說明河南生產麥子的狀況。河南的小麥，多面，食之養人，比江淮所產之小麥，質量高的多。其中通許所產的黃瓜仙麥，品質最好。其面粉清代列為貢品。面粉中所含之營養成分有：蛋白質每百克約含12克，脂肪約含 1.4克，糖約含7.4克，核黃素約含0.08毫克，尼克酸約3.4毫克，無機鹽約含0.6克等。由于蛋白質含量較高，故其新麥所磨之粉，面筋特多，并帶清香，清代進貢時，多將其新麥粉，裝入內襯黃陵之楠木匣中，車運半月方至北京。開匣后，其面粉香甜可口，別有風味。




    The quality of wheat produced in Henan is much better than that in Jinaghuai region. In Henan Province, cucumber fairy wheat produced in Tongxu is the best, which has been regarded as a tribute in Qing Dynasty for its superior quality. The flour contains various kinds of nutrition such as protein, fat, sugar, riboflavin, niacin, inorganic salt, etc. Because of its high level of protein, flour made by new-harvest wheat contains more gluten and is more fragrant, which can sustain its original flavor and smell when kept in caskets for half a month in Qing Dynasty.
