You ask - we answer!
Here you can find a list of the most frequently asked questions about our confectionery and the related answers. Have fun reading them and expanding your product knowledge!

Why does a grey film form on the chocolate-coated marzipan products?

If chocolate is stored at too higher a temperature (> room temperature) and then cooled down again, a white or grey film may form. This film consists of fat crystals and does not constitute any serious variation in quality. The product is still completely fit for consumption. Only the appearance has suffered a little.

Why may confectionery products be heavier or lighter than indicated on the packaging?

Unfortunately, it is not possible for every product to have exactly the same weight.
The production of foodstuffs is always also subject to variations in the production process. These variations cannot be avoided and are, therefore, regulated by the law. The German Pre-packaging Regulations stipulates that the products may not fall short of the nominal filling quantity (e.g. 150g bag) as a statistical average, and lays down the tolerable negative errors that may not be exceeded for the individual product. To this end, Zentis has included a statistical weight check, using calibrated scales, in the production process.

What does GDA mean?

GDA means Guideline Daily Amounts. The Guideline Daily Amounts (GDAs) are based on the recommendations of an international scientific body. The GDAs are guidelines for the average daily amounts of calories, protein, carbohydrates, sugar, fat, saturated fat, fibre and sodium required by healthy adults (and children).

The daily requirements vary according to sex, age and physical activity. For example, a man needs more nutrients and more calories than a woman.

Recommended GDAs  Women  Children (5-10 years)
Calorific value (kcal) 2000 1800
Protein (g) 50 24
Carbohydrates (g) 270 220
of which sugars  (g) 90 85
Fat (g) 70 70
of which saturates  (g) 20 20
Fibre (g) 25 15
Sodium (g) 2,4 1,4
Do you also hold plant visits?

Zentis GmbH & Co. KG's premises have grown in line with its activities since they opened in 1917. Constant increases in production made an expansion of the premises necessary, but they soon reached their limits.

Therefore, today we have to accommodate state-of-the-art production facilities in a limited space.

We are also subject, as is every food production company, to strict statutory and in-house hygiene regulations and safety requirements (risk of accidents in the area of boiling/ filling at high temperatures, danger of slipping due to moisture/ condensation water etc.).
Please appreciate that it is not possible, for these reasons, to take groups of visitors through the production facilities and, at the same time, to guarantee the appropriate level of safety for guests and the high quality of our products.

Do you have a factory outlet?

We do not have a factory outlet. However, it is possible to visit our staff outlet store on Jülicher Strasse in Aachen.

The opening times are as follows:
Monday to Friday from 11:30 to 16:30.

Is it also possible to purchase goods in small quantities directly from you?

Unfortunately, there is no provision for a sale and dispatch of smaller quantities.
