Intramuscular fat (IMF) is fat that’s deposited between and within individual muscle fibres (cells) in the body of animals. Often also referred to as ‘marbling’, the consumers of red meat often have a preference for higher IMF meat due to an enhanced eating experience.
In this, our first in a two-part series that focuses on IMF, we lay the foundations for our discussion around IMF. We define what IMF is, and describe why the increasingly discerning consumers prefer meat that contains a higher percentage of IMF. We further scene set around fat metabolism with a discussion around the four key fat depots found in a finishing animal and what roles these fat depots play in the day to day existence of our sheep and cattle.
In Episode 33, we’ll build further on this IMF topic by looking at a deeper level of detail around animal and nutrition-based factors (at a farm level) that influence the extent of IMF deposition in finishing cattle and sheep.
