Measure meat drip loss: weigh a meat sample before and after chilled storage to get the drip loss as a percentage, the fluid lost and the loss rate per hour.
Try sample values — fills the form with the worked example below.
–
Drip loss (%)
–
Fluid lost (g)
–
Loss rate (% / hour)
Equation: Drip loss (%) = (initial weight − weight after storage) ÷ initial weight × 100. Fluid lost (g) = initial weight − weight after storage. Loss rate (% per hour) = drip loss (%) ÷ storage time in hours.
Method: Drip loss by the bag method for MEAT, Honikel (1998): a weighed meat sample is hung or laid in a bag at chilled temperature for a stated time, the fluid that drips out is not reabsorbed, and the sample is weighed again. This tool is the meat drip-loss calculator; the seafood drip-loss tool is a separate tool (Tool 158) with seafood storage practice, and the two must not be mixed.
Assumptions: the fluid lost is drip only — no evaporation from an open surface and no fluid clinging to the bag counted as sample weight; both weighings are on the same scale and the storage temperature stayed chilled throughout.
Limitations: drip loss depends on storage time, temperature, muscle and cut, so values are only comparable under the same conditions; the test measures fluid lost, not the reason for it (pH, protein state, freezing damage).
Rounding: drip loss and loss rate to 2 decimal places; fluid lost to 2 decimal places; intermediates unrounded.
This is a calculation aid, not a laboratory report — confirm against your accredited method before citing a value.

Worked example: A 100 g meat sample weighs 96.5 g after 24 hours of chilled storage. Fluid lost = 100 − 96.5 = 3.5 g; drip loss = 3.5 ÷ 100 × 100 = 3.50 %; loss rate = 3.50 ÷ 24 = 0.15 % per hour.
Enter values above to see results.
Pork drip loss of 2–5% after 24 hours is common; over 5% usually points to a water-holding problem. Tool 143 of 500 — GIFSQ
