Analysis on the Wheat Quality in China in 2020

Abstract

In order to investigate the wheat quality in China, representative wheat covering more than 70% of the province were collected, based on wheat cultivars and planting areas. A total of 1,971 samples of wheat harvested in 2020 were collected for quality index evaluation. The overall level of crude protein content and gluten content is high, and the average values are 14.3% and 33.1% respectively. The quality of gluten is slightly poor, and the average value of gluten index is 68. The average flour stability is 7.1 min, and 32.8% of the samples accord with the requirements of strong gluten wheat (8 min). The overall level of maximum resistance and energy of extensograph test is general, and the average values are 355 EU and 70 cm2 respectively. In terms of food quality, the overall quality level of noodles was good, with the average score reached 81, and 74.2% of the samples reached over 80 points. The overall level of steamed bread and bread processing quality are general, with the average food score are 74, and the samples with more than 80 points are 30.5% and 43.3% respectively. The cake processing quality is poor, and the samples with more than 80 points account for only 14.3%. The proportion of wheat meet the standard of “High quality wheat-Strong gluten wheat” (GB/T 17893—1999) is 7.7%, 0.007% meet the standard of “High quality wheat-weak gluten wheat” (GB/T 17893—1999), and 36.5% meet the standard of “Quality classification of wheat varieties” (GB/T 17320—2013), of which 28.3% meet the requirements of high quality wheat. and 6.6% are high quality of strong gluten wheat, The proportion of wheat meeting the standard of “Quality Grain and Oils of China - Wheat” (LS/T 3109—2017 ) is 78.4%, of which the proportion of strong gluten and hard wheat is 6.8%.
