Minimising Wastage and Ensuring Safety in the Meat Chain

Meat Science

Meat Science

  • Minimize the wastage that occurs during the whole meat value chain
  • Food (meat) safety
  • Increase the nutritional intake of those who are currently undernourished (specifically protein intake)

Area/s of Food Security (Access, Availability, Utilization) that project/s fall under:

Availability and to a lesser extent, utilization.

How does the Project fit in with the FSI VISION?

These projects will develop new models of practice that will ultimately lead to safer and more affordable sources of protein.

Goal/s of your Projects

  • Evaluation of wastage has shown there are substantial losses in the  storage and freezing of game meat and organs. Further  research is needed to determine whether this can be minimized.
  • The quantification of the nutritional value of meat and meat products
  • Development of technologies to ensure that more affordable meat products are developed

Objective of the Project/s

  • To increase the protein intake of those who are undernourished
  • To strengthen the cross disciplinary nature of the virtual Meat Research Group
  • For the Meat Research Group to become self sufficient as pertaining to funding (this also entails using the funds from the OSP to leverage external funds).

What will the Outcomes of the Project Be?

Meeting the vision of the FSI

The research will be conducted across various disciplines thereby bringing a new and fresh approach to addressing the needs of the people for more affordable yet nutritious protein food that has meat as a major protein contributor.

The different areas of Food Security (Access, Availability, Utilization)

Will allow better utilization of meat products due to increased knowledge of the nutritional value of the products.
