Description

  • Resealable UV resistant bags protect the strips from the elements and make them easy to store
  • 50 long test strips per bag, all of which can be cut in half providing upwards of 100 tests
  • Determine how potatoes will fry before frying them, ideal for quality controlling potato production facilities
  • Just cut the potato in half and apply the strip – no need to cook the potatoes or process them for accurate readings

The Potato test paper is designed to detect sugar levels in potatoes. The amount of free glucose is directly proportional to the darkness of the potato once fried, thus the strip can be used to determine color prior to deep frying. Potato test paper can also be used to demonstrate osmosis across a membrane, by showing that glucose, but not starch, crosses the barrier. The color chart indicates concentration levels in mg/dL but this can be converted to mmol/L by multiplying by 0.055. eg. 100mg/dL is equal to 5.5 mmol/L.

Instructions:
1.Select 5 or more potatoes from the lot of potatoes of which you want to determine the sugar content.
2.Cut one potato in half lengthwise.
3.Take one potato test paper from the bag. Do not handle the test strip with your hands except where you grasp it to remove it from the bag.
4.Apply the strip 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.
5.Immediately remove the strip from the potato.
6.Wait 1 minute. If the strip remains yellow, it indicates that no glucose sugar is present and potato chips will fry a light color.
7.If the strip turns green, compare it with the color chart. Any strip darker than the 1/10% color will likely fry to dark.
8.Wipe knife blade before cutting the next potato.
CAUTION: Discard all potatoes which come into contact with the test strips. Do not process a potato to which the test strip has been applied. Potato test paper is not intended for medical diagnosis.
