DDW offers a specific, proven elderberry colouring for raspberry vinaigrettes.
To achieve the stability required in ambient dressings or dips, manufacturers need to either reach a pH below 4.2 or cook the product. Colourings which are stable in ambient salad dressing also work in refrigerated dressings, although the reverse is not always true. Anthocyanins, lycopene and caramel colour are some recommended sources of naturally derived colour for refrigerated dressings.
A common heat stable colouring in dressing is turmeric. Most of the carotenoid colourings – beta-carotene, lutein, annatto and lycopene -- are found in dressings. Balsamic vinegar may contain Class IV caramel colour. Chlorophyll provides a green hue to spinach or a green goddess dressing/dip.
Because salad dressings are a balance between water and oil systems, solubility requirements determine DDW’s colouring selection. If the dressing manufacturer does not perform their own emulsions, DDW offers oil soluble products and our EmulsiTech™ line of Natural Color Emulsions.
The chemical structure of carotenoid colouring provides oil solubility.
