Total Acidity in Egg and Egg Products

Simple chemical analysis of egg products and eggs thanks to CDR FoodLab with very easy and quick sample preparationIn some preparations for food products containing eggs, some specific enzymes are added in order to free the fatty acids. The Total Acidity test allows to check the total quantity of acidity and to monitor the enzymatic reaction.

CDR FoodLab® simplifies and speeds up the traditionally used procedures, enabling to perform many analyses in few time and with small quantities of sample as is.

Test principle

The Acidity of the sample (with pH 7,0) react with a chromogenic compound and decrease the color. The optical density, measured at 630nm, is proportional to the concentration of Free Fatty Acids in the sample.

Calibration Curve

CDR FoodLab® method shows a very good correlation with the reference method.

Reagent test Kits

The reagents are packaged in foil pouches containing 10 tubes useful to perform 10 analyses.

This is the minimum package that allows the use of CDR systems even to those who need to make a few analyses, thus not wasting reagents.

There are also boxes of 100 tests, however, packaged in 10 bags of 10 tubes containing the reagent.

Code *300241 suitable for 10 tests

Code *300240 suitable for 100 tests

The reagents have a shelf-life of 12 months.

Processing – Sample Volume – Measuring Range

Powder egg: dissolve 1 part of egg in 3 parts of water and homogenize the solution. Liquid egg: use sample as is.

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.
