Potato sugar test strips indicate free glucose sugar content caused by the breakdown of starch and is directly proportional to darkness/browning by deep frying; only $19.95 per 50 strips.

Comparing prices? We supply 50/pack AND you can cut them in half to get 100 tests per pack. Either way, much cheaper than Tollen or Benedict tests.

We have 2 other glucose test strips that can be used in lab experiments. One is for measuring glucose in urine and the other is measuring glucose osmosis rates.

  • Select 5 or more potatoes from the lot of potatoes of which you want to determine the sugar content.
  • Cut the potato in half lengthwise.
  • Take one test strip from the vial. Do not handle strip with hands except where you grasp it to remove from the vial.
  • Apply the ribbon flat to the length of the potato and press the two halves of the cut potato back together so that all parts of the strip are moistened with potato juice. Immediately remove the strip from the potato.
  • Wait one minute. If ribbon remains yellow it indicates that no glucose sugar is present and chips will fry a light color. If the ribbon turns green, compare it with the color chart.
  • Any strip darker than the 1/10% color (1st green shade) will probably fry to a dark color. Wipe knife blade before cutting next potato.

  • The number of strips (50) per bag is approximate.
  • Shelf life is 2 years but if bag is properly sealed, they should be good for a minimum of 5 years.
  • Strips will degrade if exposed to sunlight and come in a dark bag to prevent this. Do NOT transfer to a clear bag or strips will degrade quickly.
