Abstract
The invention discloses a wheat flour quality control method, which mainly comprises the following steps: cleaning and removing impurities from wheat grains, storing at the ambient temperature of 2-6 ℃, grinding into flour, and detecting the crude protein content, glutenin macro-aggregate content and glutenin macro-aggregate storage modulus of the flour. The stored protein of the flour tends to shrink and aggregate gradually along with the prolonging of the storage time to form larger aggregates. According to the thermodynamic principle, the storage temperature can influence the structure of protein in wheat grains, and further influences the physical and chemical properties of the wheat flour protein. The invention regulates the change of the protein structure by regulating the storage environment temperature of the wheat grains, thereby realizing the purpose of regulating the physical and chemical properties of the wheat flour protein.

Background
Wheat is one of three major food crops in China, and wheat flour products are main consumer products of staple food in China. Protein is one of the main components of wheat grains, and the application quality of wheat flour depends on the content and composition of the protein. Proteins are classified into SDS-soluble proteins and SDS-insoluble proteins according to their solubility in Sodium Dodecyl Sulfate (SDS). SDS-insoluble proteins are primarily glutenins, known as Glutenin Macromers (GMP). GMP is formed by the linkage of high molecular weight glutelin subunits (HMW-GS) and low molecular weight glutelin subunits (LMW-GS) by disulfide bonds. HMW-GS plays a very important role in determining the gluten network structure, LMW-GS has a special role in dough extensibility, and GMP content and GMP rheological properties have a strong correlation with bread volume and bread elasticity. The breeding of good variety (special wheat), wheat blending (new, old wheat and different varieties), wheat flour, flour blending and food modifier addition (oxidant, enzyme preparation, wheat gluten and the like) are all important methods for improving the physicochemical properties of the wheat flour protein. The newly harvested wheat is still a living organism, and is subjected to synthesis and decomposition of certain substances, and the quality of the wheat changes to different degrees along with the prolonging of the storage time and the difference of the storage conditions.
