Herbs and spices are natural products that are cultivated and harvested by hand. Finding and ensuring premium qualities for you is one of our core competencies. Through our direct co-operation with the producers and processors, we guarantee that strict standards are maintained right at the source. This reduces contamination and the risk of mould developing, and also improves the overall microbiological status. Additionally, certain product risks are minimised through the application of the test plans we have for each of our natural raw materials.

Raw material checks

All raw materials, such as spices, herbs, vegetables and functional ingredients, are invariably subjected to a quality control and evaluation when being delivered. After carrying out systematic sampling, we perform extensive chemical, physical and microbiological incoming goods inspections to allow us to ensure that value-determining ingredients are included in the appropriate quantities, and that inferior or unsuitable raw materials do not enter our production process.
The scale of testing carried out at our facility therefore depends on the type and origin of the raw material, as well as its internal risk classification; it also depends on the amount of preliminary testing and monitoring carried out by the supplier. As a result, each of our raw materials has its own test plan in our laboratory data processing system.
We check whether the goods purchased around the world fulfil our requirements, and whether these goods are worth the price being charged for them. We also analyse the value-determining, natural ingredients of our raw materials, such as
  • their flavour components (“essential oils”)
  • pungent substances (“piperine” in the case of pepper)
  • general quality parameters
  • hygienic condition
  • residual moisture (which give information about storability and shelf life)
Hygienic condition, purity and the value-determining ingredients are the requirements for WIBERG product quality. Many raw materials therefore need to undergo at least 20 different tests before they are released for production and permitted to enter processing.
