flavour8 suspension testing in molten chocolate

At TasteTech we actively test our products to prove their unique qualities and how they work in an end application. By doing this we are able to provide our customers with the highest level of technical information and support they require.

Purpose:

We recently conducted a suspension test of our flavour8 ginger, flavour8 clementine and flavour8 peppermint against a control unflavoured sample. The purpose of this experiment was to see the impact of flavour release in molten chocolate over a 28 day period.

We melted 4 x 400g batches of chocolate at 50 degrees Celsius, mixed flavour8 into each batch at the relevant dosage and agitated them for 5 minutes. Each batch was then poured into a pre-warmed glass bottle and stored in a temperature controlled incubator at 50 degrees Celsius as shown below.

In Test
The samples were then checked for any perceptible odour release every 7 days and gently re-agitated for 30 seconds before being placed back into the incubator.

Results:

The table below states the results over a 28 day period.

Observation:

The results of the test confirm that after 28 days all three flavours exhibited excellent stability, with no perceptible odour even when the chocolate had not been mixed for some time. Observations during the testing period highlighted a slight separation of oil from the bulk chocolate mass due to the lack of continuous agitation. This can however be attributed to the chocolate’s high oil content, and not to the flavour8 as this occurred in the control as well as the test samples.
