The shelf life of a product begins from the time the food is prepared or manufactured. Its length is dependent on many factors including the types of ingredients, manufacturing process, type of packaging and how the food is stored. It is indicated by labelling the product with a date mark.
How do you determine the shelf life of a chemical?
Chemical Shelf Life is the time period in which a specific chemical product retains the same properties and characteristics that it possessed at the time of packaging. This period is often identified as an expiration date*(see expiration date), which is set by the chemical manufacturer.1 sept 2019
How shelf life is determined by the manufacturer?
Analyse results – In the absence of standards (legal or voluntary), manufacturers have to set their own end point based on microbiological, chemical or sensory criteria. The shelf life date is usually assigned as the last day of an acceptable sensory score or analytical results.9 dic 2015
How do you predict shelf life?
What is Shelf Life Prediction? Shelf life prediction is a technology that has risen with the need to track the freshness of food. Currently, static testing is the most common way of measuring shelf life. This involves leaving produce on a shelf and waiting for it to expire.7 jul 2020
Is shelf life testing a legal requirement?
There is no specific legislation on how to set a shelf life for ambient stable goods. ... Manufacturers can use shelf life testing as evidence of due diligence for retailer standards. Accurate shelf life assessment can also help to reduce food waste.12 oct 2018
Why shelf life testing is necessary?
Shelf-life testing is designed to provide an objective measure of the quality factors that define the food and the point at which failure occurs. This failure is the point at which the food exhibits physical, chemical, microbiological, or sensory characteristics that are unacceptable to the consumer.1 jul 2000
How do you test accelerated shelf life?
To run an accelerated shelf life study, the most common method used is the kinetic model approach. Its process involves: Selection of kinetic factors for acceleration of deteriorative process. Running study of deterioration process at such levels of accelerating factors that deterioration is fast enough.
How do you evaluate shelf life?
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.
