Factors affecting weight loss in meat by drip and evaporation (and how to minimise them):
|
Factor |
Effect |
What you can do |
|
Chilling rate |
Considerate chilling reduces evaporative losses: cold shortening |
Understand from your supplier(s) their chilling procedures insist on considerate chilling |
|
Pre-slaughter stress |
Can lead to poor water retention/high drip loss can ensue |
Visit your abattoir; Scotch Beef and Scotch Lamb should undergo heavily monitored pre-slaughter checks to reduce stress levels |
|
Meat pH |
High pH meat (>pH 6.0) has low drip loss |
Many factors involved (see Abattoir section) |
|
Electrical stimulation |
In conjunction with considerate chilling, Electrical Stimulation (ES) can reduce evaporation |
Understand from your supplier(s) their procedures (see Abattoir section) |
|
Size of meat pieces |
Drip loss in joints and roasts are 10 times lower than in steaks and chops (due to surface area) |
Understand the benefits to you and write specifications accordingly |
|
Packaging |
Pressure exerted on meat by tight fitting films can increase drip loss |
Understand the implications to you and write specifications accordingly; speak to your butcher and see what other packaging methods could be used |
|
Freezing and thawing |
Drip loss can double as a result of freezing |
Manage your deliveries to reduce the volume of meat that needs to be frozen; minimise non-blast (rapid) freezing, or freezing completely |
