What is happening?
Following customer feedback on our planned discontinuation of crude fibre testing due to the unavailability of a critical consumable, we have now identified a suitable automated solution to maintain crude fibre testing capability.

 

What do I need to know?

We are currently in the process of installing the new system, and carrying out method validation and instrument qualification before we can begin using the method. 
Once the automated system is in place, we will carry out a cost analysis, and our test pricing may be adjusted accordingly.

We anticipate that the current test code and method reference will remain unchanged.
We anticipate having the new system operational by the end of June. In the meantime, crude fibre analysis will continue using the existing manual method to ensure uninterrupted service.

What is happening?

We are introducing a change to reporting of Vitamin E analysis using the AOAC 2012.10 method to include a comment stating whether a natural or synthetic conversion factor was used, and which standard was followed in making the calculation.

 

What do I need to know?

Analytical methods are incapable of separating natural (d- α-tocopherol) and synthetic (dl- α-tocopherol) isomers of Vitamin E, however results must be calculated using different conversion factors, depending on whether the source of the Vitamin E is natural or synthetic, to correct for their different biological activity. In order to be explicit about the conversion factors used for the calculation of Vitamin E test results, we are updating our test reporting. 

 

What happens next?
The AOAC 2012.10 method is already in use for Vitamin A and E testing and there is no change to this method.
The updated reporting for Vitamin E along with new test codes will be introduced from 31 May 2024.
We will update all product specifications to use the new test code.
Please update your LabConnect templates as required.

What is happening?

The MIMM Membrane Filtration methods for Total Coliforms, Faecal Coliforms and E. coli water monitoring are being discontinued and replaced with the American Public Health Association (APHA) Standard Methods for the Examination of Water and Wastewater.

 

What do I need to know?

Changes to the MPI Consolidated List of Tests (CLT) have allowed for the analysis of many regulatory Microbiology water tests to be performed using the APHA Standard Methods. The way AsureQuality performs Membrane Filtration Total Coliforms, Faecal Coliforms and E. coli testing is technically equivalent for the MIMM and APHA methods.  As such, there is no longer a benefit to customers for the laboratories continued support of both reference methods. Due to the breadth and depth of expertise involved in the maintenance of the internationally recognised APHA Standard Methods, we have opted to continue to offer these methods and discontinue support of the MIMM.

 

What happens next?

We will update all contracts, product specifications, and LabConnect templates as required to incorporate the APHA methods, and we’ll transition analysis of your water samples to the equivalent APHA Membrane Filtration water methods. 

 

Analysis codes for Total Coliforms, Faecal Coliforms and E. coli MIMM Membrane Filtration water methods will be deactivated no later than 19 February 2024.

What is happening?
We are pleased to advise that AsureQuality now has IANZ accreditation for the testing of Mesophilic Rope Spores in Cereal and Cereal Products.

What do I need to know about the test?

Ropiness is a quality defect that can occur in most flour-based baked goods, due to contamination by bacteria known as Rope Spores found in the environment, or more likely, in ingredients used in manufacture. When breaking open an affected product such as a loaf of bread, a strong odour like decomposing fruit is noted. Discoloured soft portions that can be drawn out into long threads, giving a “stringy” or “ropy” appearance will also be obvious.

 

AsureQuality is the only laboratory able to provide this analysis as an IANZ accredited test.

 

What happens next?

From now on Certificates of Analysis will automatically show as an accredited test for the test code GM-BCIL09 Variation 01 where it has been used for testing on Cereals or Cereal Products.

What do I do now?

There is nothing you need to do. This communication is simply to notify you that our Rope Spore test results are now formally accredited by International Accreditation New Zealand (IANZ), bringing you more value at no extra cost.

What is happening?
From 23 October, we have released two new test codes that can be used to improve the accuracy of Lactose Carbohydrate Ratio calculations. The previous single test code that was available worked on the asumption that the Lactose composition was unknown. However, where the composition is known, more definitive results can be obtained.

What do I need to know about the test codes?

We have introduced two new test codes to allow for a more refined calculation to be made where the Lactose Composition is known to be primarily Monohydrate or Anhydrous.

 

What happens next?

We will continue to use the default test variation for unknown Lactose Compositions unless you advise us otherwise. 

What do I do now?

At your earliest convenience we invite you to update any product specifications with the new test codes. Once you have updated the product specifications please click the "Accept this change" button to the left and attach the forms to the email acceptance. Any LabConnect templates that contain the current test codes will need to be updated prior to use.
