Packaging is directly related to food safety in two ways. First, if the packaging material does not provide a suitable barrier around the food, microorganisms can contaminate the food and make it unsafe. However, microbial contamination can also arise if the packaging material permits the transfer of, for example, moisture or O2 from the atmosphere into the package. In this situation, microorganisms present in the food but posing no risk because of the initial absence of moisture or O2 may subsequently be able to grow and present a risk to the consumer.
For example, there may be transfer of moisture vapor from a humid atmosphere into a dried product, or transfer of an undesirable odor from the external atmosphere into a high-fat product, or development of oxidative rancidity if the package is not an effective oxygen (O2) barrier. , plasticizers from plastic film). In addition to the ability of packaging materials to protect and preserve foods by minimizing or preventing the transfers referred to, packaging materials must also protect the product from mechanical damage and prevent or minimize misuse by consumers (including tampering).
