Assessing Milk Thermal Processing: A New Method

The chemical analysis of the milk and dairy products for quality control for every stage of the production chain with CDR FoodLabPoster at Congrilait 2002: furosine and milk processingOne of the parameters most currently used to assess milk thermal processes is Furosine (a product resulting from Maillard’s reaction). The method used to determine this parameter is however very expensive, requires a lot of time and the use of an HPLC system and, consequently, qualified personnel.
CDR’s research laboratories have developed an innovative method that enables to determine the amount of powder milk added to raw and pasteurized milk and thus assess the effectiveness of the most commonly used thermal processes (pasteurization and UHT treatment). In this study, CDR has demonstrated that it is possible to determine the type of thermal process by measuring the concentration of e-Fruttosyl-Lysine, which is also produced during Maillard’s reaction.

Analysis for milk thermal processing assessment

The content of e-fructosyl-lysine was measured in 5 milk samples that had been heated with different processes.

Samples that had not been previously processed were tested using CDR Foodlab®.

After an initial reaction of 5 minutes, researchers calculated the slope of the regression line. Data demonstrate an excellent correspondence between the content of e-fructosyl-lysine and the milk thermal processing. In addition, using CDR FoodLab®, the test is particularly simple to run because of the easiness of use and short testing time required by the system.

F. Bonicolini, M. Bicchiega, from the biochemical laboratories CDR s.r.l., presented at Congrilait 2002 (26th IDF World Dairy Congress Paris, 24-27 September 2002) the results of the study. The relative poster is entitled Maillard reaction evaluation by e-fructosyl-lysine during milk thermal processing: first step.

With the CDR system, you can perform your tests in total autonomy

Neither skilled staff nor a dedicated external laboratory is needed to use our systems. CDR FoodLab® optimizes traditional testing methods, making them faster and easier, while guaranteeing accuracy standards in line with the reference methods.

Analytical kit

CDR FoodLab® Analysis Systems use disposable pre-vialed reagents specifically developed by the research laboratories of CDR. The use of pre-vialed reagents and the analytical procedures allow:

  • a sample preparation that is quick and easy, when needed at all;
  • making analytical procedures extremely fast and easy;
  • removing all needs for complex calibration procedures.

Reagents come in aluminum packages containing 10 test tubes each to perform 10 tests (or packages for 100 tests containing 10 single packages of 10 test tubes each).

Just a few steps and results are yielded right away

Just a few steps will suffice to carry out your analysis in a rapid way in total autonomy. The system is composed of both the analyzer based on photometric technology and a kit of low toxicity, pre-vialed reagents, developed by CDR.

CDR FoodLab® is cost-effective because it does not require the use of expensive equipment and does not entail maintenance, assistance or calibration costs.
