Vitamin C Test Strips: Measure Ascorbic Acid Levels Fast!

Vitamin C Test Strips

These vitamin C (ascorbic acid) test strips are great for biology labs or home use. Test your favorite fruit juices to see if the vitamin C levels are as advertised. These strips are calibrated such that 0.01% equals 10mg/100ml and 0.1% is equal to 100mg/100ml, etc..

Fruit juices that claim 100% or more of RDA will very likely show >0.1% concentration (the strip maximum). To compare accurately, you need to dilute them. e.g. 9 parts water, 1 part juice equal 1 in 10. Then, multiply the strip reading by "10" to get the real value. Try to compare similar juices since tomato & apple may look a little different even if the vitamin C level is the same. Different types of lighting can affect the appearance. If in doubt, try sunlight.

Lime juice is actually yellow but concentrates can have green dyes added that can give a pinkish-purple result and all you can infer are relative strengths. That is, pink indicates 16 times the strength of deep purple.

full strength......pink
half strength.....dark pink
1/4 strength.....light purple
1/8 strength.....purple
1/16 strength...deep purple

Try the following with the same volume of a given type of juice (sealed containers should no room at the top for air):

Put an unsealed container in the refrigerator
Put 2 sealed containers in the refrigerator; 1 is a control
Put an open container on your countertop (loose cover is ok)
Put a sealed container on the countertop

After 5 days (or more) take one of the juices stored in a refrigerated, sealed container & boil gently for 15-30 minutes. Now compare the Vit. C levels in all 5 containers; the 2nd sealed, refrigerated container is the control. Is there be a difference? Why?

Note (2): The number of strips per pack or vial is approximate.
Note (3): Works with any form of acorbic acid; eg. calcium ascorbate or sodium ascorbate
