Development benefits company, client and environment

Thanks to a transparent supply chain, carefully designed operating processes and thorough quality control, we can guarantee the high quality and safety of our products. We actively develop solutions and products that support our customers in their businesses. Open communication with our stakeholders as well as tight cooperation with research institutes and local companies ensure that we are constantly getting new information about our products. This information we use to improve the safety and refining possibilities of our products even further.

The innovative mindset and nature-conservation measures of Honkajoki Oy have received recognition from Finnish authorities.

Active cooperation with research institutes

We tightly collaborate with various research institutes in order to develop processes and practices that are based on agroecological principles and circular economy. The research results are applied to our own production operations as much as possible. We also collaborate with our machine and device suppliers to develop our technological resources and machinery. Our research partners include VTT Technical Research Centre of Finland, the University of Helsinki, Tampere University of Technology, Lappeenranta University of Technology, the University of Jyväskylä, the University of Vaasa and MTT Agrifood Research Finland.

Careful quality control prevents risks

No product is dispatched to the customer without a clean approval from quality control. We actively monitor the quality of raw materials and products, and many different microbiological analyses are carried out on the products. Samples from our product line are taken daily, and each sales batch is carefully reviewed before dispatch. We comply with the monitoring programme, which defines for example the studies to be carried out, the analytical and sampling method and the preventive measures. The monitoring programme consists of statutory procedures for good hygienic practices and production methods. Our laboratory partners are Eurofins Scientific Finland Oy, Seilab Oy, Fin FurLab Oy, as well as the laboratories of Finnish Food Safety Authority Evira.

Sampling methods

The production line is sampled continuously with an active sampling probe.

The collection samples of a sales batch are compiled into a composite sample to be submitted to the self-control laboratory for analysis.

Frequency of checks

Samples from the production line are collected daily.     

The samples are analysed per sales batch. 


The results can be obtained from the lab within five working days.     

The results are delivered electronically to the results service and signed certificates of analysis are delivered by post to the plant.     

The results are kept in a locked cabinet.

Corrective and preventive measures

The production line is cleaned and kept tidy according to the plant’s self-control programme.     

The products are always analysed before delivery to the customer.     

If the limit values for the analysis are exceeded, the product is not delivered to the customer.
