河南自古就是小麦的主要产地，《诗经》上记载有“我行其野，芃芃其麦。”类似这些记载尚有很多，都说明河南生产麦子的状况。河南的小麦，多面，食之养人，比江淮所产之小麦，质量高的多。其中通许所产的黄瓜仙麦，品质最好。其面粉清代列为贡品。面粉中所含之营养成分有：蛋白质每百克约含12克，脂肪约含 1.4克，糖约含7.4克，核黄素约含0.08毫克，尼克酸约3.4毫克，无机盐约含0.6克等。由于蛋白质含量较高，故其新麦所磨之粉，面筋特多，并带清香，清代进贡时，多将其新麦粉，装入内衬黄陵之楠木匣中，车运半月方至北京。开匣后，其面粉香甜可口，别有风味。




    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.
