The Prüf Nach! standard defines the guidelines necessary to implement our eight values and achieve the highest possible product quality.

Our unrivaled procedural quality management ensures that all aspects of a food product are considered and coordinated as sustainably as possible. The objective is to retain the value and variety of food. 

Preserving the vitality and individuality of food

Many processes take place by the time a raw material becomes the final food product – from cultivation to production to processing. The manufacturing process not only changes the composition of the food, it also reaches into other aspects, such as the order of and interaction between ingredients, what is natural, what is alive.

Primary agricultural production, with only a few exceptions, is geared towards generating the most uniform, compliant products for industrial processing. The preference is for varieties and breeds that are oriented towards market needs and improve the profit margin.

Foods that are produced according to the guidelines in procedural quality management preserve as much of their natural composition and structure as possible. Vitality and nutritional value are retained, while the individuality and complexity of the food can be tasted and smelled. This way both high and consistent quality is preserved.

Foods have many dimensions

All foods originate with plants and animals that are bred, cultivated, gathered, hunted, or fished for nourishment. Every living being constantly interacts with its environment. The reactions to influencing factors are extremely diverse and reflect the living conditions.
As a result, all agricultural products in their unprocessed form bear the signature of the farmer, the region, the soil, the surrounding biosphere, and the climate. 

Typical reactions from plants are the formation of varying degrees of root systems depending on the amount of water or the development of protective mechanisms against predators. Animals react to illnesses by forming antibodies.  The food available also has a major influence – regardless of whether it is animal feed or soil nutrients for plants. Even living things with a relatively similar genetic make up can be very different depending on their origins.

How is procedural quality management implemented?

Companies that introduce procedural quality management like Prüf Nach! have to clarify some critical issues: What are the most appropriate technologies and parameters to preserve the natural character of the raw materials and ingredients? How can the special features specific to the variety and region of the raw material be retained? How can the vitality and complexity of the sensory – perceivable by the senses – qualities of the food be fostered?

This is why every partner in a food’s production chain has to exercise as much care as possible. Defects in raw materials and semi-finished goods cannot – as is common practice these days – be compensated for with technology or ingredients. This requires the close coordination of all partners and a high level of maturity in dealing with food products. Food products are not just a means of nourishing oneself, they represent a complex interplay between living, chemical, and physical factors.
