Technical data sheet
Print- Method description
Samples containing phytic acid are extracted with acid and reacted with phytase and phosphatase to release phosphorus. This is then quantified with a color reaction of Ammonium molybdate. Free phosphorus is subtracted from the total, and released phosphorus is determined. Phytic acid can be calculated from this release phosphorus.

Common Phytic Acid Test Testing Questions
Samples containing phytic acid are extracted with acid and reacted with phytase and phosphatase to release phosphorus. This is then quantified with a color reaction of Ammonium molybdate.

Yes
Grains (whole wheat, oats, rice), Legumes (black beans, peanuts, lentils), nuts and seeds
Cooking, soaking overnight in water, sprouting (germination), fermentation, and pickling can all break down phytic acid so that the phosphorus can be released and absorbed by the body.
We make every effort to keep our methods and detection limits up to date according to the latest standards and qualifications. If you have any questions regarding the limit of detection/quantification or method references, please contact our Customer Service team at 1-800-245-5615.
Our standard turnaround time is 10 business days for most assays. There are some assays that require a longer turnaround time. We also offer a RUSH service that is half the time of the standard turnaround time of the assay at double the cost of the assay. A few assays that we provide cannot be rushed due to the nature of the test. Please check the specific assay you are interested in regarding the ability to RUSH the turnaround time.
