Special Issue Information

Dear Colleagues,

Grain products constitute a fundamental component of the global diet; their quality, authenticity, and safety are directly linked to public health and economic value. Traditional methods for assessing grain quality and detecting adulteration are characterized by time-intensive procedures and high operational costs, which limit their applicability for real-time and on-site monitoring. The development of rapid, cost-effective, and non-destructive analytical techniques is, therefore, critical for effective quality control and food safety assurance.

This Special Issue, "Novel Approaches for the Detection of Grain Products' Quality and Adulteration," aims to showcase recent scientific and technological advancements in the food industry. We invite original research and review articles focused on innovative approaches to assessing grain quality and authenticity. Topics of interest include—but are not limited to—rapid and non-invasive analytical methods, advancements in spectroscopy and imaging technologies, sensor-based detection systems, machine learning and artificial intelligence for data interpretation, and the identification of adulteration practices and their implications for human health. Contributions addressing novel quality markers, authenticity verification strategies, and traceability technologies are also highly encouraged.

This Special Issue seeks to provide a comprehensive platform for emerging methodologies and interdisciplinary strategies that can enhance the integrity, safety, and value of grain-based food products.

The quality of glutinous rice flour (GRF) plays a critical role in determining the processing suitability of Tangyuan, a traditional Chinese glutinous rice-based food. This study systematically characterized the physicochemical, pasting, textural and digestive properties of twelve representative GRFs, as well as the cooking behaviors of the resulting product of Tangyuan. The results revealed that different GRFs displayed varied protein, total starch and amylopectin contents. The microstructure of Tangyuan exhibited three main types: robust and dense (e.g., H1 and H3), porous and soft (e.g., S1 and S4), and fragmented and disrupted (e.g., S2 and S3) networks. Rheological and pasting profiling revealed that doughs with extreme rigidity (G′ > 104 Pa) and high setback values exhibited rapid retrogradation, leading to severe frost cracking during cold-chain storage. Tangyuan with moderate G′, loss tangent (tan δ) below 0.35, and balanced peak viscosities provided optimal viscoelasticity for both mechanical machinability and freeze–thaw stability. Furthermore, S5 with naturally high resistant starch contents significantly attenuated the hydrolysis index, successfully shifting Tangyuan from a high-glycemic to a medium-glycemic profile. The results provide valuable insights into the screening of raw glutinous rice flour from different origins, offering theoretical guidance for the standardized production of freeze–thaw-stable and low-glycemic functional Tangyuan.
