Preserving food is a crucial part of product development within the food industry. Whether it's sauces, juices, jam, marinades or beverages: without a well-thought-out preservation strategy a safe and commercially viable shelf life is impossible.
For manufacturers and private label projects preservation is not only about food safety, but also about legislation, clean label positioning, export possibilities and cost efficiency.
In this blog we share the main principles for professionally preserving food products.
What is food preservation?
Preservation means controlling or removing factors that cause bacterial growth, mold formation or quality loss. Micro-organisms require certain growth conditions. By influencing one or more of these factors, shelf life can be extended significantly.
The main knobs you can turn:
-
pH value (acidity)
-
Oxygen
-
Temperature
-
Water activity (Aw value)
-
Preservatives
An effective preservation strategy often combines multiple techniques.
