Working with Nature and Technology

While there is an unbroken demand for vibrantly coloured foods, consumers have become increasingly suspicious of artificial and so-called “natural additives”, considering them a potential threat to their health and that of their children.

GNT is the pioneer in the field of Colouring Foods. With more than 30 years of experience in providing a full range of colours, we are in the unique position to offer you an easy-to-use product and any support you may need in developing applications using fruit and vegetable concentrates.


Colouring Foods generally have a characteristic taste related to the raw materials. The dosage levels required typically have no impact on the taste of the finished product. We help our customers select the appropriate EXBERRY® product and, if necessary, make minor adjustments to the formulation.


At GNT, we process nearly 30 different fruit and vegetable varieties to give you just the shade you need. Many shades are available, among them stable reds, greens, yellows and oranges – and also shades of blue.



EXBERRY® Colouring Foods offer good to excellent light stability. When the packaging is transparent or contains a window, stability to light during storage is a critical consideration.



EXBERRY® Colouring Foods are typically water-soluble or water-dispersible. Nevertheless, they may be used in applications for which oil-soluble colours are typically required. We will be pleased to work with you to find the perfect solution for your application.

Heat stability

Generally speaking, EXBERRY® Colouring Foods demonstrate very good stability to heat and can be used successfully, even when quite extreme heat processes such as high boiling, pasteurisation, etc. are used. Please do not hesitate to ask us about the specifics – we are here to help.


Colouring Foods containing red fruit and vegetable concentrates are typically pH sensitive, while other shades are less influenced. The colour shades of such pH-dependent Colouring Foods may vary in application. GNT’s technologists can provide expert advice in this respect.


With more than 35 years of experience in the food industry, GNT has great know how not only in developing and manufacturing stable and intensive Colouring Foods but also in the production of various food and drink applications like confectionery, bakery products, beverages, dairy products and others.

The GNT food experts are able to advise their customers on all questions relating to the application of EXBERRY® Colouring Foods and assist in taking into account diverse factors that could have an influence on the colour performance, such as heat-treatment, pH levels, possible oxidation, packaging of the final food or beverage product or the climatic conditions of the country it will be sold in.

For this purpose we offer numerous workshops to our customers in our application centres. Each workshop focuses on a special product type and gives detailed insights in technical issues like colour influencing factors and how to deal with them.

The program of the workshops contains theoretical talks as well as practical hands-on sessions in which the attendees can experience the performance of EXBERRY® Colouring Foods themselves.

Both the attendees and the GNT specialists perceive these workshops as valuable events to gain useful information and to strengthen the relationship.
