We believe the quality of the ingredients directly reflect the quality of the finished product. That is why, at Kettle & Fire, we aim to use the best possible ingredients in order to get the best possible product.
As you know, the two main ingredients to make bone broth are bones and water.
In order to get water with the highest level of purity, we use a filtration process known as reverse osmosis. This is a highly efficient process and it delivers pure water suitable for different applications.
Osmosis does actually occur in nature. This is the process where two solutions are separated by a semipermeable membrane, and the solvent moves from the less solute to the more solute concentration in order to achieve equilibrium. Reverse osmosis is the exact opposite of the osmosis process.
Since water is recognized as a “universal solvent” it contains many dissolved minerals and a many microorganisms - calcium, magnesium, fluoride, oxides and many other chemicals, as well as bacteria and other pollutants. During the process of reverse osmosis (RO), the solvent (in our case the water) is forced by high pressure to pass through a semipermeable membrane leaving the impurities, dissolved minerals and microorganisms in the more concentrated solution, producing pure water.
The filters used in the process of reverse osmosis are made of dense layers of polymer materials, designed in such a way as to only allow the water molecules to pass, containing all other dissolved materials. This process is done using high pressure, ranging from 30 to 250 psi, ensuring that the produced purified water is of highest possible quality, and is suitable to be used in medical, many industrial processes as well as for food production.
The whole process of reverse osmosis uses less energy than other purification processes which enables the conservation of energy and allows for water with the highest possible purity, ensuring that our bone broths will have the highest possible quality.
