Shelf Life Testing: A Critical Step in Food Safety
Posted by Ilsa Miller on September 23rd, 2023
What is shelf life testing?
Food shelf life testing is a process used to determine how long a food product will remain safe to eat and retain its desired quality. The shelf life of a food product is affected by a number of factors, including the type of food, the packaging, the storage conditions, and the intended use.
How to determine shelf life?
The shelf life of a product can be determined using a variety of methods, including:
Accelerated shelf life testing (ASLT)
This method uses controlled conditions, such as higher temperatures or humidity, to speed up the aging process. ASLT can be used to get results more quickly, but it is important to note that the results may not be directly applicable to real-world storage conditions.
Real-time shelf life testing (RTSLT)
This method uses actual storage conditions to test the shelf life of a product. RTSLT can be more time-consuming than ASLT, but it is the most accurate way to determine the shelf life of a product.
This method tests for the presence of microorganisms, such as bacteria and mold, that can spoil food. Microbiological testing can be used to determine the shelf life of a product, but it is important to note that not all microorganisms can be detected using this method.
This method uses human panelists to evaluate the appearance, taste, smell, texture, and overall quality of a food product. Sensory evaluation can be used to determine the shelf life of a product, but it is important to note that the results may vary depending on the panelists.

What are the factors that affect the shelf life of food?
The shelf life of a food product is affected by a number of factors, including:
The cost of food shelf life testing can vary depending on a number of factors, including:
The type of product: The cost of testing a perishable product, such as fresh fruits and vegetables, will be higher than the cost of testing a non-perishable product, such as canned goods.
The complexity of the test: The more complex the test, the higher the cost will be. For example, a test that includes microbiological analysis will be more expensive than a test that only includes sensory evaluation.
The number of samples: The more samples that are tested, the higher the cost will be.
The length of the test: The longer the test, the higher the cost will be.
The laboratory: The cost of testing will vary depending on the laboratory that is used. Some laboratories are more expensive than others.
In general, the cost of food shelf life testing can range from a few hundred dollars to several thousand dollars.
