The shelf life of a food product depends on many factors. Among the most important are:<\/span><\/span><\/h3><\/header>

<\/p>\n

The GBA POLSKA laboratory has at its disposal climatic chambers allowing stability tests to be conducted under controlled, set conditions.<\/p>\n

The implementation of accelerated storage tests is based on the application of van ‘t Hoff’s rule, which describes the change in reaction rate depending on the change in temperature.<\/p>\n

It is used to verify the shelf life of foodstuffs and feedstuffs that are stored in climate chambers under defined conditions of temperature and humidity. The most commonly used conditions are a temperature of 40 degrees C and a humidity of 75%.<\/p>\n

Shelf life is the period of time during which a product must:<\/p>\n
