The process
Biosa's products are manufactured through a fermentation process, where lactic acid bacteria and herbs are mixed with water and molasses. The lactic acid bacteria convert the sugar in the molasses into organic acids. These organic acids make the products self-preserving, and when the last trace of sugar in the molasses is converted, the fermentation process is complete. Once the fermentation process is finished and the product has been tested and approved, we bottle and label the product. Then it is ready to be sent out to stores around world.

1. Raw ingredients
In our production, we use organic ingredients. Biosa's products mainly rely on four ingredients: lactic acid bacteria, herbs, molasses, and water.

2. Fermentation
Our products are made through a natural fermentation process. Fermentation is one of the oldest methods for preserving products, but the process also has several other benefits.

3. Packaging
In our production, we use bottles made from at least 50% recycled plastic (RPET) to reduce the amount of plastic waste.

4. Quality control
All our products are continuously checked, both by ourselves and by an externally accredited laboratory, to ensure that they meet our high quality standards.

Biosa sources its raw materials from registered suppliers. As part of Biosa's quality management system, our suppliers are regularly evaluated to ensure that we maintain our high standards. We use strains of bifido- and lactic acid bacteria, selected based on their different pH and temperature optima to optimize the fermentation process. Lactic acid bacteria are essential for the fermentation process our products undergo because they produce organic acids, primarily lactic acid and acetic acid, which give our products their unique tangy taste while ensuring that the products are self-preserving.
All of our products are fermented with 19 organic herbs, not only to support the fermentation process but also to impart the products with their unique, rich flavor. During fermentation, the herbs are removed from the mixture, so our products only contain extracts from the 19 herbs. All of our herbs are certified organic.
Biosa’s products are fermented with organic cane molasses, which has a sugar content of about 60%. Molasses is the brown substance left over after the sugar, which later becomes refined white sugar, has been extracted. The high content of easily digestible carbohydrates in our molasses ensures an efficient fermentation process. The lactic acid bacteria convert the molasses into organic acids, primarily lactic acid and acetic acid. The fermentation process continues until all the sugar has been converted, making all of Biosa’s products sugar-free.
2. Fermentation
Fermentation has played a significant role in human diet and nutrition for thousands of years. The fermentation process occurs naturally in an oxygen-free environment, where carbohydrates are converted into organic compounds (such as lactic acid and acetic acid) with the help of yeast, bacteria, or a combination of these.
The benefits of fermentation include the conversion of sugars and other carbohydrates to create natural preservatives directly in the food, as seen in sour foods such as pickled dairy products, kombucha, and kimchi, where microorganisms produce organic acids directly in the product.
The main purposes of fermenting foods are:
- to develop and ensure taste, aroma, and textures.
- to make the product naturally self-preserving.
3. Packaging
All our bottles are made from at least 50% recycled PET (RPET). We encourage everyone to sort the bottles as hard plastic after use, so we can all help keep the recycled in circulation.
All the cardboard we use is produced from recycled paper to the highest extent possible – and can, of course, also be recycled.
There is no doubt that more that can be done, and fortunately, new initiatives in sustainable alternatives are constantly emerging. Therefore, we always try to stay updated on the latest research, challenge traditional thinking, and motivate towards a healthier lifestyle for each other, and our planet – through every choice we make!
4. Quality control
Throughout the production process, we closely monitor the fermentation process. We take samples from each batch, which are sent to a microbiological analysis at an accredited laboratory. This is to ensure feed and food safety and to monitor the development of lactic acid bacteria.
We measure the pH value frequently to ensure that the fermentation progresses as expected. It is an essential parameter as it reflects the production of organic acids (lactic acid and acetic acid). Thus, the pH value serves as an indicator of product quality.
The final part of our quality control occurs during bottling, where we taste-test our human products to ensure they have the desired, unique acidic taste.
As a company, we are also subject to inspections by the Danish Veterinary and Food Administration, which continuously monitor our production.
