Spirulina cultivated in Saxon, Valais
Spiruline-Valais is cultivated in Saxon, in the heart of the canton of Valais, in ponds installed inside greenhouses. A complete ecosystem has been created there to provide favourable conditions for growing spirulina.
In partnership with Agroscope, we carry out regular analyses to monitor water quality and verify the absence of heavy metals and pesticides. Our ponds are filled with natural Alpine water, heated inside the greenhouses by solar energy. Our spirulina is cultivated without products of animal origin, pesticides or herbicides. Spiruline-Valais contains no additives, is not irradiated and is produced without GMOs.
Our spirulina production follows the rhythm of the seasons. Harvesting takes place mainly from April to the end of October, before a winter break.
In short: water, sunshine and life, all coming together to produce a local spirulina cultivated directly in Valais.
Quantity and quality analysis
A cultivation sample is taken from the middle of the pond. With this sample the population density of spirulina is analysed and calculated in order to determine the optimal date for harvesting.
Microscopic analysis
At this stage, a quality control of the spirulina is carried out using a microscope. Every spiral which can be distinguished represents a spirulina.
Harvesting and filtration
The micro-algae is harvested from the pond with a pump and filtered through a fabric of a very fine-mesh.
Pressing the spirulina
Spirulina is then pressed by means of a vacuum pump in an equipped packaging room.
Extrusion into fine strands
The drained biomass is passed through a hydraulic pusher to obtain fine spirulina filaments.
Low-temperature drying
The spirulina spaghetti are dried on a low heat (40 degrees Celsius) in order to preserve cellular integrity. We thus obtain an end produt that is highly nutritious and easily assimilated by the body.
Processing into flakes
The flakes are obtained after a fast grinding of the dried filaments
Packaging on the farm
All the spirulina produced is packaged on the farm. It is provided in opaque, airtight bags or in recyclable cardboard boxes with a bio-sourced and biodegradable compost cap.
Tasting of the final product
You can mix 3g (1 coffee spoon) into honey, yoghurt, cottage cheese, stewed fruit, fruit juice, smoothies… or sprinkle it on toast or salad.
