New safety model for dried meat products in DMRI Predict

The collection of safety models is expanded with a new member, the model for dried meat products. The model predicts the growth of Listeria monocytogenes, Salmonella and E. coli in the dried meat products based on a series of variables in the used recipe and process: 

  • Days: 1-365
  • Added amount of salt (NaCl) to recipe: 3.0-7.0%
  • Water in product: 60-75%
  • Added nitrite: Yes/No
  • pH of raw material: 5.30-6.55
  • Packaging method: Aerobic/Anaerobic
  • Weight loss over time: 0-35% for max. 365 days

The available temperature ranges are:

Constant: 10-30 °C

Dynamic: 10-30 °C for 1-365 days

The model output is growth or decay of the three pathogens, changes in water activity (aw), changes in salt concentration in the water phase (WPS), and a visualization of the temperature course throughout the chosen period.
