Oyster mushroom goes in the “Doubleganger and Zwarma”

Feb 13, 2020

With “Doubleganger and Zwam” sausage rolls, grower Mariëlle van Lieshout from Liessel in the Netherlands wants to encourage consumers to eat more oyster mushrooms. "There are many opportunities, but you have to see them and you have to be patient."

Van Lieshout from Liessel is a busy bee: she has her own oyster mushroom farm, develops innovative ideas for mushroom cultivation with Mobichamp and is a board member of the oyster mushroom association. For the latter, her main motivation is that she wants consumers to eat more oyster mushrooms. The association has a study club to learn from each other in the field of cultivation.

We are trying to develop new products, because only betting on the consumption of fresh oyster mushrooms is not enough. There are many opportunities, but you have to see them and you have to be patient.

RIJP
The entrepreneur has recently joined the RIJP platform developed by farmers, ZLTO and Geodan. The aim is that farm shops, caterers and retail can purchase a diverse package of regional products from farmers from the platform. Such a regional product is the “Doubleganger”, which Van Lieshout came up with together with regional product store 't Streeckhuys in Deurne the Netherlands. It is a hamburger in which half of the meat has been replaced by oyster mushrooms.

“With the Doubleganger belongs the slogan: the only male hamburger that your wife also wants to eat”

The Doubleganger contains less fat, salt and calories and more fiber and taste than a regular hamburger and is a sustainable and healthy choice without consciously eating less meat," says Van Lieshout. 'We use the following slogan: the only male hamburger that your wife also wants to eat. That fits in nicely with that.

Wider range
All breeders who are members of the oyster mushroom association may market the Doubleganger. "We hope that we can reach a larger audience with a limited marketing budget," says the entrepreneur.

Van Lieshout also stood at the basis of the Zwam sausage roll, with a filling of half oyster mushrooms and half pork. 'An additional advantage is that you can store such products in the freezer for six months, while you can only sell oyster mushrooms fresh. With this, we hope to somewhat offset the peaks and troughs in sales in the future. "

Van Lieshout has also found a new destination for the stalk of oyster mushrooms, normally a residual product. The Eindhoven designer Doreen Westphal from Botanic Bites has been pioneering with tapas, saté and sausage from the stalk since 2016. In 2019 she came up with a variant on shoarma meat: Zwarma.

The grower also implements sustainability in other areas: the straw from the cultivation packages goes back on land as a soil improver and the nursery has 343 solar panels, good for a capacity of 100,000 watt-peak.

PlanetProof
The nursery is PlanetProof certified, but Van Lieshout is not interested in organic certification. 'The demand for organic oyster mushrooms is lower than the supply, so that makes little sense. But if that demand grows and I can get a biological substrate, I want to make the switch. " Most oyster mushrooms end up at retail companies in the Netherlands, Belgium and Germany and can be kept for around a week after purchase.

Companies sometimes offer the entrepreneur their coffee grounds to be processed into the substrate for oyster mushrooms. 'I want to think along with that, but then I also expect something in exchange , for example, that they will sell the Doubleganger or the Zwam sausage roll in their canteens. It must be beneficial for both parties. "

As a daughter of mushroom growers, Van Lieshout had a dream: the mushroom farm of the future. 'A mushroom can grow up to 4 percent per hour and therefore a picker has to make many decisions. With smart software I wanted to make harvesting easier and more automated. " It was not possible to get the financing for the own nursery, but the idea did not let her go.

Harvest guide
Together with two partners, Van Lieshout founded software company Advanced Mushroom Research in 2011. The Harvest Guide, developed by them, measures properties such as diameter, bulging of the hat and structure of the mushrooms above a growing bed. Colored lights on selected mushrooms then give picking advice to the picker.

At Koolen Champignons in Slootdorp there is a test setup of the Harvest Guide. With this the initiators hope to interest mushroom farms all over the world. 'The next step is robotization of the picking process. That is desperately needed, because it becomes more difficult to find and retain harvesting staff, "says Van Lieshout.
