In 2022, the simple barns of the past will no longer work, even if you gave everything you had, as evidenced by the painted inscription of this dilapidated barn. universalipic@pexelfarm.



If we want to tell something about the history of potato preservation, we have to go back to the time when the potato was first written about. The first indications of a finding of starch from the potato come from South America. It is said to have been found in that region 12,500 years ago, in present-day Peru and Chile.

One of the most important figures in the history of the European potato was the physician and botanist, Carolus Clusius. Born in French-speaking Flanders, later the Southern Netherlands, this botanist lived from 1526 to 1609.

Through his research, he has made an important contribution to the development of the Solanum Tuberosum variety and the introduction of this potato as a food crop in our European regions. On his wanderings through southern Europe, he became acquainted with many other scientists, especially in Portugal, Spain and Turkey. He took the cuttings of the different varieties with him to his Hortus in Mechelen, and by breeding different varieties were already created. He also brought them to the Hortus in Leiden. In 1594 he became a professor in Leiden, where he headed the Hortus Botanicus until his death in 1609. The Clusius Garden can still be admired next to the entrance building of the Hortus.

Despite all efforts, it took until 1727, when the potato was only accepted as a complete food in Friesland. Due to the important nutritional value of carbohydrates and vitamin C, the potato became increasingly important in times of hunger. In the current time, the potato can no longer be ignored from our daily food, and comes in many variations. Breeding, breeding, protecting and preserving has become a trademark. The Netherlands has now climbed to the number 2 position in the world.

Storing the potato is not so easy to figure out. An Indian tribe from South America, the Quichua, lives in the Andes mountains, mainly in Chile and Peru. She was the first to describe how she could preserve the potato by making flour from it. The Andes Mountains are known for its capricious mountain landscape and the associated large temperature differences. The days are warm, up to 30°C, and the nights cold, down to -10°C. These differences were used for both growth and storage.

When the harvest was taken from the fields, a selection was made between consumption and storage. The lots were split and the lot intended for consumption was divided among the tribes. The batch to be stored was moved to the areas with the coldest temperatures at night, and there the potatoes were spread on mats on the bottom to freeze. The next morning they returned and the potatoes, which had now softened, were pounded into a pulp with bare feet. This pulp was moved to the warmest places in the sun, where the pulp dried into powder. In this way the flour was made from powder, which was kept in barns for years after the harvest, depending on the weather need.

Later in time, ways were found to preserve the potato in its entirety, as we do today. In Colorado, USA, the potatoes were placed in deep, hard-to-reach caves up to 60 meters deep. A constant temperature of 4°C and optimum humidity was maintained here, in order to keep the potato in the best condition. From that period it has been described that there was no discernible difference at all between the new harvest and, the potatoes that had been stored in the cave for 2 years, no color or even no difference in taste. Very special.

In the Netherlands, after the war, often existing sheds were used for the storage of potatoes. Few materials were available and one had to make do with everything available. Simple thatched barns, with only one opening as an entrance door. Tools were pure and mechanical, powered by horse and manpower. Later, tractors and electricity came as drivers for further mechanization.

One of the first companies that specialized in potato storage was owned by the Tolsma family. As early as 1952, this family was active in the north of the country, trading in white goods and installing electricity in the barns of farmers. Later on, electrical installations with fans, and thus the first storage sheds arose. In 1966, in Emmeloord, they started manufacturing ventilation systems and air ducts, an innovation in storage technology at the time. It has now become Grisnich-Tolsma, a specialist in potato storage with a solid reputation all over the world. Another big name in storage technology is Omnivent, located in the town of Zeewolde. This specialist has also been around for a long time, since 1986, and is active worldwide. Omnivent is an important player in the storage technology for food in the broadest sense. Both companies are leaders in the market, each in their field.

This prominent position has not been obtained by itself, the development continues every day. Food preservation is a theme of urgency worldwide, wasting is no longer an expression of luxury….
