Checking particle segregation when MSG size changes in a dry soup mix

Set up the comparison

Record the sizes of MSG and base particles. Take samples at the beginning, middle and end of packing and compare them at the same reconstitution ratio.

Measurements to record

Specific rotation (Under specified conditions). The published table specifies the D line at 20°C. Agree the solvent and concentration in the contract. Particle size distribution (µm or % sieve residue). State sieve opening and percentage passing. For fine or agglomerated material, specify dispersion and sieving procedures. Record the sample ID and method revision for repeat testing.

Interpreting the results

Rule out segregation and sampling error before attributing differences in umami to the raw material.

What to record

• Ingredient particle sizes
• Packing interval
• Sample mass
• Reconstitution ratio
• Sensory result
