“…Te viscoelasticity of grains is strongly related to their composition, especially the water content. Moisture content afects the viscoelasticity of grain to a great extent, the most important of which is the elastic modulus of grain [62]. Te uniaxial compression experiment of wheat further verifed this result.…”

Grain is extremely vulnerable to external loads during production and processing, resulting in the deterioration of grain quality. Deteriorated grain not only affects the economic value of grain but also affects the safety of storage. This has a very important relationship with the biomechanical properties of grains. It is of great significance to explore the mechanical properties of grain under different conditions and analyze the relationship between its physical and chemical properties and mechanical properties for improving its processing and eating quality. In this paper, the research methods of the mechanical properties of grains are reviewed. Various factors influencing the mechanical properties of cereals were analyzed. The relationship between the internal organizational structure of grain and its mechanical properties was discussed. This paper puts forward the shortcomings in the current research on the mechanical properties of grains and puts forward the prospect and analysis of its importance in future development in order to provide a reference for reducing crushing in the grain processing process.

“…The mass of the same volume of ground grain or grain mixture should be higher than the mass of the extruded product. This should be four or more times higher for peas and corn and two, three, or more times higher for wheat, barley, and other crops [45,186,187].…”

“…The quality of extrudates depends on many factors, including the following: the composition of the raw material, its humidity, the method of preliminary preparation, the temperature, the duration and intensity of the mechanical impact on the raw material, the design of the screw, etc. [187]. Extrudates of grain feed are lighter in color than the raw material and have a pleasant bready taste and smell.…”

Triticale, a hybrid of wheat and rye, is one of the most promising grain crops. In terms of productivity, the level of metabolizable energy, and the composition of essential amino acids, triticale surpasses rye and is not inferior to wheat. It is resistant to the most dangerous diseases and pests. In terms of nutritional value, triticale can compete with wheat, corn, sorghum, and barley. The presence, however, of antinutrients in triticale such as non-starch polysaccharides, alkylresorcinols, and trypsin inhibitors significantly reduces the biological value of this crop. In the global practice of compound feed production, there are many methods and technologies for processing grain raw materials to increase their nutritional value. Enzymatic treatment and extrusion technologies are worthy of special attention. The high content of triticale in the compound feed of poultry breeder flocks should be used effectively, taking into account the characteristics of triticale varieties and climatic conditions. An optimal triticale level in feed (15% for layer and broiler chicks) may improve body weight gain and reduce feed costs when raising replacement young stock. Layer breeder flocks fed a 20% triticale-based diet may have increased egg production, high viability, and flock uniformity. Producing triticale–soy and triticale–sunflower extrudates and supplementing the diet of poultry flocks with essential amino acids represent promising avenues for maximizing the benefits of triticale. Innovative methods of achieving this goal should be further developed and put into practice, particularly given the expansion of triticale’s cultivation areas.

BackgroundRapid and accurate detection of moisture content is important to ensure maize quality. However, existing technologies for rapidly detecting moisture content often suffer from costly equipment, stringent environmental requirements, or limited accuracy. To bridge this research gap, this study proposes a simple and effective method for detecting moisture content of single maize kernels based on viscoelastic properties.ResultsTwo types of viscoelastic experiments were conducted, involving three different parameters: relaxation tests (initial loads: 60, 80, 100 N) and frequency sweep tests (frequencies: 0.6, 0.8, 1 Hz). These experiments generated corresponding force‐time graphs and viscoelastic parameters were extracted based on the constitutive model. Then, viscoelastic parameters and data of force‐time graphs are employed as input variables to explore the relationships with moisture content separately. Furthermore, the impact of different preprocessing methods and feature variables on model accuracy is explored based on force‐time graphs. The results indicate that models utilizing the force‐time data have superior accuracy than those utilizing viscoelastic parameters. The best model is established by partial least squares regression based on S‐G smoothing data from relaxation tests conducted with initial force of 100 N. The correlation coefficient and the root mean square error of the calibration set are 0.954 and 0.021, respectively. The corresponding values of the prediction set are 0.905 and 0.029, respectively.ConclusionsThis study confirms the potential for accurate and fast detection of moisture content in single maize kernel using viscoelastic properties, which provides a novel approach for the detection of various components in cereals.This article is protected by copyright.
