Abstract

The storage of bread-making wheat is a critical stage in the post-harvest chain, directly influencing the final quality of the product intended for the food industry. This study investigates the physicochemical behavior of the RO1 wheat variety stored in uncontrolled flat warehouses located in the Valea Seacă area, Bacău County. These storage facilities, characterized by the absence of automated microclimatic control, require careful monitoring of environmental conditions to preserve product quality. Between September 2023 and August 2024, 48 samples were collected and analyzed to evaluate key parameters such as moisture content, temperature, hectoliter weight, gluten level, and protein level. The findings indicated notable variations in these attributes, closely associated with seasonal climatic changes. Atmospheric humidity and temperature exerted a direct influence on the product’s moisture and temperature, resulting in modifications to the internal composition of the wheat. The research highlights the critical role of ongoing environmental monitoring in uncontrolled storage areas and underscores the necessity of implementing fundamental hygiene practices and adequate ventilation. Despite infrastructural limitations, flat warehouses remain a practical option for rural farmers, as long as strict conservation measures are followed. The study improves understanding of wheat quality degradation during storage and offers concrete recommendations for better post-harvest management in uncontrolled environments.
