Predictive modelling pilot trial on vacuum skinned beef through a retail supply chain

12 April 2019
Focus area: Food safety
Program stream: Product & process integrity
Project number: 2018-1074
As part of this project, the shelf lives of vacuum-skin-packed (VSP) products were examined in a simulated domestic supply chain. The shelf life of these products was compared with that predicted by a UTas/MLA vacuum packed (VP) beef shelf life model to evaluate the reliability of the model.

All VSP steaks had a shelf life from 37 to 41 days. These shelf lives were much longer than the shelf lives (between 22 and 27 days) based on the microbiological criteria. This reinforces those microbiological criteria for shelf life determination are not appropriate as an indicator of product quality. However, aging of rump primals for up to 56 days had only marginal effects on the shelf life of VSP products based on both microbiological quality and odour attributes. This offers some flexibility in the process of producing VSP products to meet customer’s expectations without significant effects on their shelf life.
