Typical scenario

Canned-pea mass calculated together with packing liquid

If a whole can’s contents are compared with declared drained-product mass, the calculation may answer a different question. Liquid and solid portions need separate determination by an appropriate procedure. Preserve labels before opening and establish which quantity the disputed number describes.

What needs to be clarified

Review drained-product mass, drainage procedure and sampling, comparing results with the relevant declared quantity for the submitted canned-pea lot.

Materials to prepare

  • Unopened cans with lot identification and declared masses
  • Drainage protocol describing sieve, time and temperature
  • Raw weights of cans, tare, sieve and drained product

What to compare

Clarify label and method definitions. Check sample preparation, sieve size, drainage duration and absence of extra squeezing. Recalculate allowing for tare, retaining every can’s result. Assess sampling and variation separately; never substitute total contents weight for the separated solid portion.

Possible outcome of the analysis

A checked calculation may tabulate each can and assess quantity comparability, identifying repeat measurements needed after drainage deviations or inadequate sample traceability.

Limits of the conclusions

Arbitrary squeezing changes the result and is not methodical drainage. Quantity examination does not establish microbiological properties or safe consumption; lot conclusions depend on justified sampling.
