Development and assessment of new preservation strategies
Depending on the complexity of the process and products, proposing a combined preservation strategy can be more effective, using an integral vision of the process and ingredients to bring various conventional or newer technologies into play at different stages of the process.
These strategies can be applied to the elaboration process of a new product, as well as to adapting or improving an already existing process, with the aim of mainly improving its sensorial characteristics.
Designing the strategy requires a stage prior to developing knowledge about the raw materials, the processing stages and the final product: its associated risks and the final product’s impact on safety.
Thanks to this we can achieve:
- New validated and documented combined strategy. Scientific evidence
- New products
- “More natural” “like freshly-made” products
CNTA Methodology:
| 1 | Developing knowledge about raw materials and the different stages of the process to be developed, from the perspective of its associated risks and the impact on safety of the final product. |
| 2 | Analysing and identifying the microbiological risks of the product |
| 3 | Assessing the potential for growth or the growth mechanism of a specific pathogen in a specific product |
| 4 | Microbiological reduction studies to demonstrate the lethal nature of a specific process (“Challenge test”) |
| 5 | Assessing the impact of the treatment on the physical-chemical and organoleptic qualities of the food |
| 6 | Final validation of the integrated process |
Furthermore, in this case each of the stages and technologies put into play must be assessed individually when it is necessary to assess its impact. At CNTA we approach the development and validation of new preservation strategies in 6 steps.
Depending on needs and objectives, they are addressed collectively or just those necessary.
