20 Apr How to Determine Expiration Dates for Your Food Product
Determining an accurate expiration date is critical for food safety, brand reputation, and regulatory compliance. Shelf life testing provides the scientific data needed to establish “best by,” “use by,” or “expiration” dates.
The process begins with identifying key risk factors such as moisture content, pH levels, water activity (aw), and ingredient stability. These factors influence microbial growth and product spoilage. Laboratory testing then evaluates how the product performs over time under controlled conditions.
Microbiological testing checks for pathogens like Salmonella, Listeria, and E. coli, while chemical and sensory analyses monitor rancidity, flavor, color, and texture changes. Packaging also plays a crucial role, as oxygen permeability and seal integrity can significantly impact shelf life.
Regulatory bodies like the FDA require that expiration dates be supported by scientific evidence. Without proper testing, brands risk recalls, compliance issues, and loss of consumer trust.
Working with a certified food testing lab ensures your expiration dates are accurate, defensible, and aligned with industry standards.
