Flavors, Fragrances & Aroma Chemicals worked example

Shelf-Life Loss with daily degradation or evaporation loss of 9 kg / day: a worked example in flavors, fragrances & aroma chemicals

Here is what the math looks like when conditions slip. We hold every other input steady and drop daily degradation or evaporation loss to 9 kg / day, then walk the calculation through step by step. Estimate cost of flavor, fragrance, essential oil, solvent, or aroma chemical inventory lost to expiration, retest failure, oxidation, evaporation, or customer shelf-life rules.

The inputs for this scenario

  • Daily degradation or evaporation loss: 9 kg / day (the input this scenario stresses; the baseline uses 18)
  • Days held at risk before use or retest: 30 days (held at the documented default)
  • Material cost: 22 $ / kg (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Shelf-Life Loss consumed = shelf-life loss rate × days at risk before use or retest.
  • Shelf-Life Loss quantity works out to 270 units at these inputs, and this is the headline figure for the scenario.
  • Shelf-Life Loss cost works out to 5,940 $ at these inputs.
  • Days at risk before use or retest works out to 30 hr at these inputs.
  • Material cost works out to 22 $ / unit at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where daily degradation or evaporation loss sits at 18 kg / day and the headline result is 540 units, this scenario comes in 50% below the baseline at 270 units.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to daily degradation or evaporation loss, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes a constant daily loss rate, but real degradation is often nonlinear and temperature-dependent, so it best approximates moderate holding periods under stable storage.
