There are many advantages of the use of liquid smokes, created by the combustion of hard woods : maple, beech, oak or hickory. However, it is important to specify that the smoke processes using our liquid smokes allow the production of smoked products without bezopiren or tars residues, and without discharges of smoke. So, it is possible to protect the environment , to reduce the duration of smoking cycles and the costs against the traditional smoking process (less cleaning, reduction of insurance polices due to the presence of heat source, etc.).
