The production of SWISSOJA tofu

At SWISSOJA, we exclusively work with certified organic soya beans sourced from Switzerland. We stongly support local supply chain due to the severe repercussions of deforestation on animal and plant species resulting from the extensive cultivation of soya beans in South America, primarily for animal feed purposes. SWISSOJA’s products form an integral component of a sustainable diet, dedicated to conserving the Earth’s natural resources.

Growing soya beans in Switzerland has been the focus of intensive agronomic research for several decades, owing to its status as an exotic plant with high thermal requirements. Thanks to our breeding efforts, soya beans have successfully acclimated to the favorable regions of the Swiss plateau. The most optimal production areas are found in the lower temperate sites of the plateau, benefiting from consistent water supply during the summer.

The harvest

From the filed to the mill…

Soya beans are harvested from early September under favorable conditions. By the beginning of October, the pods reach maximum maturity.

The sorting process

The harvested soya beans are transferred to the mill for sorting, cleaning, hulling, and sometimes dehulling as well.

The soaking process

From soya beans to soya juice

Upon arrival at the SWISSOJA production site, the organic soya beans are washed and soaked in water for ten to twelve hours. By the end of this soaking process, the beans have doubled in size.

The grinding process

The swollen and softened soya beans are then ground with water in a lava stone mill.

The boiling process

The mashed soya beans are then boiled in an autoclave

The filtration process

and filtered to separate the residual fibrous material : Okara, from the soya juice, more commonly known as soya milk.

The curdling process

From soya beans to soya juice

The process of transforming soya juice into tofu is similar to making cheese. Just as the artisan cheesemaker adds rennet to coagulate the milk, the tofu master adds nigari to coagulate the soya milk. Nigari is a crystal extracted from seawater, serving as a natural source of marine magnesium chloride and traditionally used in Japan as a coagulation agent. Due to its addition, the soya juice coagulates, forming grains of curd. The gentle stiring separates the curds from the lactoserum.

The pressing process

The curd grains are transferred to a molding mold, where they are pressed into blocks of firm tofu. The blocks are then cut into the desired weight and shape before being cooled in water. This process makes the firm, plain tofu that is widely recognized and appreciated! Flavored tofu is produced similarly, with an additional step involving the incorporation of carefully selected ingredients.

As for the smoked tofu, undergoes ‘cold-smoking’ using certified Swiss-origin beechwood sawdust sourced from the forests of Vaud. old smoking imparts a delicate smoke flavor to the tofu, providing its distinctive and authentic taste without subjecting it to high temperatures.
