Shelf life

Shelf-life studies that show how long your candy keeps

A shelf-life study tells you how long your candy keeps and what limits it: moisture, texture, bloom or flavor. I design the study, decide what to measure and help you read the results.

Shelf life

What I help with

  • Study design

    Conditions, time points and sample counts that answer your question.

  • What to measure

    Moisture, water activity, texture and appearance, chosen for your candy.

  • Accelerated studies

    Faster answers from warmer storage, and their limits.

  • Reading the results

    What the data says about your date and your packaging.

  • Packaging

    How the wrapper or bag affects moisture and texture over time.

  • Fixing what fails

    Formula and process changes when a study shows a problem.

Note

I don’t have my own lab, so studies are designed around your facility or an outside lab.

Questions

How long does a candy shelf-life study take?

A real-time study runs as long as the shelf life you want to claim. An accelerated study at warmer conditions gives an earlier read, which the real-time study then confirms.

Do you run the tests?

No. I don’t have my own lab. I design the study, your team or an outside lab runs it, and I help you read the results.

What limits shelf life in candy?

Most often moisture: candy picks up or loses water, and its texture changes. Fat bloom, crystallization, flavor loss and stickiness are other common limits, depending on the candy.
