Passionate about onions

Internationalquality


Jonika’s roots lie deep within Zeeland’s clay-rich soil. The company was set up by Joost Nieuwenhuijse in the middle of the last century. Based in the town of Oostdijk, Jonika was envisaged as a grading and packing station for onion growers in the Dutch coastal province of Zeeland. Soon, the onions were being bought by customers all over the Netherlands and far beyond. And the company went from strength to strength. As Jonika grew, it began sourcing onions from beyond its native Zeeland. Today, the onions come from quality growers throughout the Netherlands. And the family firm has become an innovative modern company and a leading player on the global onion market.

Deep roots

the third generation


Our success stems from our passion for onions. A passion handed down from father to son, so that today the company is run by a third generation of the Nieuwenhuijse family. Over the course of Jonika’s history, the focus has gradually shifted from the grading, storage and packaging of onions to the cultivation process itself. Because it is the way an onion is grown that determines its quality. Expert cultivation produces a top-class onion, an onion of the very best quality. A Jonika onion.

Intelligent cultivation


Jonika onions are easily recognised even when they are still in the field. Grown with loving care and only in the most fertile soils, their sturdy green stalks mark them out from the start. Today’s Jonika onion is the successful product of a vigorous and innovative selection policy, in which the environment has been considered every step of the way.

Growing


Our growers work with the very best seed and make extremely sparing use of artificial fertilizers, pesticides and other crop protectors. It is an approach that yields a truly top-class onion. Jonika attaches great value to input from growers. Much of our success is down to maintaining close ties with our growers and listening to their wishes and opinions.

Timing

HarvestingWith tender care


Onions need to be harvested with great care and precision in order to avoid damage. Our growers combine modern machinery with traditional knowledge and skill. Generations of experience go in to choosing exactly the right moment, so that the onions are harvested in perfect condition, ensuring the very highest quality. Equally important is the process of careful selection and transportation to climate-controlled storage sheds.

At Jonika, we have elevated the conservation of onions to a true art. Conservation and storage are specialist procedures, which we perform with the utmost care using modern drying systems. So that our onions retain their taste, shape, colour, skin quality and firmness.

Quality storage

Quality assured


In our warehouse we keep the onions in crates in order to dry them, a phase which is essential for the quality of the onion. The crates guarantee constant quality, in which temperature, ventilation and humidity are the most important conditions. Using innovative technology, we create the ideal climate for keeping the onions in our modern warehouse.

Jonika onions have the best possible protection throughout the time they spend in the ground. That protection continues when they are harvested and move through the various processing phases, during which they are graded, checked and packed.
