The application for the patent was published on July 17, 2026, under issue no. 29/2026.
Abstract: A novel method for the predictive detection of food spoilage is disclosed. The method involves measuring the volatile organic compound (VOC) profile of a food item using sensor arrays or spectroscopic instruments and then calculating specific ratio metrics between different classes of VOCs, such as a Protein Degradation Index (comparing amine-based to ester-based VOCs) or a Fermentation and Rancidity Indicator (comparing acid-based to aldehyde-based VOCs). The spoilage state is determined not merely by absolute concentrations but by evaluating both the current value and the rate of change over time of these ratio metrics. This dynamic analysis captures the evolving metabolic pathways of spoilage microorganisms, providing early warnings well before visible or olfactory signs of spoilage appear. By focusing on relational ratios rather than individual compound levels, the approach minimizes interference from inherent food ingredients like spices or seasonings, making it particularly effective for ready-to-eat meals and mixed dishes. The invention enables implementation on diverse hardware platforms, from portable electronic noses to laboratory-grade equipment, and supports proactive food safety management in supply chains, households, and industrial settings.
