Art. No.: RBRP129
An enzyme for the clarification of cloudy apple juice and apple purée prior to patulin analysis.
Following AOAC method 2000.02 for patulin in apple juice (MacDonald et al.: Journal of AOAC International. Vol 83: No 6, 2000.) the apple juice is treated with pectinase enzyme to clarify the sample prior to extraction. Clear apple juice does not require the addition of pectinase prior to extraction.
- Pectinase is used as part of AOAC method 2000.02 for analysis of patulin in cloudy apple juice and purée.
- Enables the analysis of cloudy apple juice and purée. Available as a ready-to-use solution.
- Each batch of pectinase is accompanied by a certificate of conformity.
we now provide the documents for our products in an electronic format which include the Instructions for Use (IFU), Safety Data Sheets (SDS), Application notes and the Certificate of Analysis (CoA). For batches placed on the market after 1st June 2023, you can find our documents on the eIFU portal eifu.r-biopharm.com.
|Test format||100 determinations|
|Sample preparation||Sample is extracted with ethyl acetate and then cleaned-up by extraction with sodium carbonate solution. Samples are pre-treated with pectinase enzyme. The ethyl acetate extract is dried with anhydrous sodium sulphate. After evaporation of the solvent, the toxin is quantitatively determined by LC with UV detection. The total sample extraction and clean-up takes approximately 2 hours to perform|
|Incubation time||2 hours at 40 °C, then centrifugation for 5 minutes or leave to settle overnight at room temperature, then centrifugation for 5 minutes.|
Cloudy apple juice and apple purée.
|Evaluation||HPLC or LC-MS/MS.|
|Approvals||Pectinase is used as part of AOAC method 2000.02 for analysis of patulin in cloudy apple juice and purée.|
