Taste Test Set
Test of the taste transfer from the packing materials and packing media through room air using the test substance water according to DIN 55534:2006-08 and the taste test set
This is a quick test, which can be incorporated into an analytical method. This is an additional test method to DIN 10955. This test is therefore a quality control measure during the production of the packing media or the packing process (for example a packing material inlet and outlet check). This sensory quick test allows the quick investigation of packing aids such as pressure media, adhesives, dyes, paints, auxiliary materials and end products.
Short description:
The sample is located in a glass vessel with a fused glass tube with one side open on the inside, the tube being filled with water. Volatile substances from the packing material are absorbed by the water. Water is a neutral food that has no taste of its own and can be savoured well. In special cases, the tasting can be done with a closed nose.* The matrix water is well suited for any further analytical investigations.
Test substance:
Boiled, low-salt, commercially available water (boiled for approx. 20 min in the water boiler!). This measure destroys organic matter and gasifies carbon dioxide.
Procedure:
50 cm² (12.5 × 4 cm) of packing material** are exactly cut out and rolled lengthwise and placed in the glass container aroundthe inner tube so that the broad side stands upright. Deviations must be agreed upon and indicated in the test report. (see image). Then, 40 ml of water are filled into the fused inner tube using the Fortuna pipette. Then, the vessel is sealed. At least two test batches are prepared for each test and evaluated separately. As a reference sample another taste test is run - the glass container with 40 ml of water without a packing material sample.
Test specifications:
Quick determination during production:
The test batches must be stored for 1 hour at a temperature of 40 °C (+/-2 °C).
Final determination for quality assurance:
the test batches should be stored for 24 hours at room temperature (23 °C +/-2 °C).
Tasting:
The tasting should also be carried out at room temperature (23 °C +/-2 °C) in an odorless test room. Approx. 10 ml of test substance (water) are extracted with a 10 ml PE pipette, placed in a taste-neutral drinking cup for tasting and assessed in comparison with the reference sample.
Taste Test Set:
* Differentiation between the flavour substances and the retronasal sense impression
** The sample surface is adjusted depending on the inherent taste of the packing substance.
