Industrial Donut Production

Industrielle Donut Produktion

What makes the quality of
donuts and berliners?

Donuts and ball donuts are still in vouge and consumers are always searching for new flavors, fancy shapes and decors and smaller portion sizes. Although, donuts and berliners should be juicy, but not greasy, soft with a short bite and with a fine texture.





When producing ring donuts and ball donuts, the shape is important. Donuts and berliners should have a perfect round shape with a slightly curved surface.


A particularly fine crumb structure and a smooth surface characterizes the quality of donuts and ball donuts.

Fat content

The right amount of fat is crucial when it comes to freshness and taste – good if you can control the fat intake.
