How do you calculate remaining shelf life? ›

and this is how we calculate remaining shelf life percentage (( Expiration Date - Today Date)/(Expiration Date - Production Date)) %.

Shelf life can be calculated directly if the product is stored under nonstandard conditions. ΔT° = T2 -T1 = 30 – 5 = 25°C. T90 (30°C) = 24 / 2 2.5 = 3.18 h T90 (30°C) = 24/ 3 2.5 = 1.2 h T90 (30°C) = 24/ 4 2.5 = 0.56 h A newly reconstituted product is labeled to be stable for 24 h in the refrigerator.

Shelf life is commonly estimated by two different stability testing procedures: realtime stability tests and accelerated stability tests. In real-time stability testing, a product is stored at recommended storage conditions and monitored until it fails the specification.

Minimum Remaining Shelf Life:-

Minimum amount of time for which the material must be kept upon goods receipt accepted by system. The function of this field is to put check during any Stock Posting. e.g. Total shelf life of product is 24 Months and in material master minimum shelf life is 2 months.

When microbiological issues are important, there are three different basic approaches that are used to assess product shelf-life: shelf-life trials, challenge tests and predictive microbiology. Each has a role to play in assuring the safety of the product shelf-life chosen.

A tool used in accelerated studies is “the rule of ten,” or Q10, which is the factor by which the rate of spoil-age increases when the temperature is raised by 10C. Q10 allows for the prediction of a product's shelf life under real-life conditions based on the results of testing conducted at high temperatures.

Shelf life simplified

This approach follows a predetermined process by eliminating the most unlikely modes of failure and focusing on the most likely modes of failure. Using the simplest method to track the mode of failure gives you an idea of when the product fails.
