Technical data sheet
Print- Method description
Samples containing pectin are digested with pectinases and other enzymes in an acetate buffer to cleave galacturonic acid. Total sample galacturonic acid is quantified using another enzymatic reaction and spectrophotometric detection. Pectin is quantified from the total galacturonic acid less the free galacturonic
- Acceptable matrices
Fruit and fruit preps, fruit fibers, purified pectins
- Unacceptable matrices
Samples with high amounts of inclusions in the Pectin
- Limit of quantitation
0.52 g/100g
- Equipment
Spectrophotometer, Centrifuge, Incubator
- Method reference
Internally developed method w/ K-URONIC 04/16, Megazyme
- Reportable unit
g/100g (%)
- Sample size requirements
20 grams
- Information required by submitter
Please supply estimates
- Additional information
Samples high in free galacturonic acid may have more variability due to the large blank subtraction. Samples with high amounts of inclusion may be underestimated due to the samples being reported as Galacturonic acid equivalents. Inclusions would not be included in that total.
Common Pectin Test Testing Questions
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.
