Signs of Spoilage

Compromised packaging (tears, holes), signs of pest infestation (small holes, webs, visible insects), significant moisture absorption causing large, hard clumps that do not break apart easily.

How to Check

Visually inspect the packaging for any damage or signs of pests. Feel the package for large, unyielding clumps that suggest moisture ingress.

Storage Tips

Store away from direct sunlight, heat sources, and areas prone to humidity. While it can last longer, quality may slowly degrade over many years.

Signs of Spoilage

Strong musty, sour, or off-odors; noticeable discoloration (e.g., yellowing or browning); hard, impenetrable clumps that do not easily crumble; presence of pests (weevils, pantry moths, etc.) or their traces; mold growth (rare, but possible with extreme moisture).

How to Check

  1. Smell Test: Inhale a small amount of the starch. It should be virtually odorless or have a very faint, neutral starchy smell. Any musty, sour, or chemical odor indicates spoilage.

  2. Visual Inspection: Look for any changes in color, signs of insect activity, or mold.

  3. Touch Test: Feel the starch. It should be a fine, free-flowing powder. If it's sticky, excessively lumpy, or forms hard bricks that can't be broken apart, it has likely absorbed too much moisture.

Storage Tips

Transfer opened arrowroot starch to an airtight container (glass jar, sturdy plastic container) immediately after opening to protect it from moisture, odors, and pests. Store in a cool, dry, dark place. Avoid storing near strong-smelling foods, as starches can absorb odors.
