Quality Control Guide

Finished Product Checks

Before a batch is released, look at the finished product itself: texture, aroma, color, appearance, dryness and package integrity. These checks catch what numbers miss, and they are the first place a quality problem surfaces.

The Quality-Control Principle

Quality control connects the food, the process and the record: batches are dried, checked, identified, packaged and documented so results are repeatable and problems are findable.

What to Check

Check realistically, per food type:

  • Texture. Matches expectations: crisp for many fruits and vegetables, flexible-but-dry for high-sugar and high-fat foods.
  • Aroma. Clean and characteristic of the food; no off, sour, oily or ammonia-like smells.
  • Color. Even and expected for the product; sudden darkening or bleaching can signal a problem.
  • Appearance. Uniform pieces, no clumping, no visible moisture or sticky patches.
  • Dryness. Confirmed again on the largest and densest pieces. See Before Packaging.
  • Package integrity. Seal, seams and surfaces intact. See Packaging QC.

Do Not Taste Questionable Product

Never taste food that appears spoiled, moldy, off-smelling or otherwise questionable. When in doubt, follow the hold or reject path. See Hold, Reject & Rework.

Using the Checks

Compare the finished product to what the same product looked like when it worked well. A sudden difference in texture, color or aroma is worth understanding before release. Record your observations in the production record: Production Records.

Frequently Asked Questions

Can I eat a sample to test the batch?

Only food that appears sound and was safely handled. Never taste food that looks spoiled, moldy or off-smelling; that is what the hold and reject paths are for.

What does a quality problem usually look like first?

Often a texture or aroma difference: softer than expected, an off smell, or a color shift. Then check dryness, because residual moisture is a common root cause.

Key Takeaways

  • Check texture, aroma, color, appearance, dryness and package integrity.
  • Compare against a known-good version of the same product.
  • Never taste food that appears spoiled or questionable.
  • Record finished-product observations in the production record.
