Liposome / Encapsulation

Liposomes are bilayer spherical lipid vesicles composed of polar lipids used in the pharmaceutical, personal care, chemical and food industries to encapsulate both hydrophobic and hydrophilic compounds. It is formed as a result of dispersion of polar lipids in a polar medium such as water. It has been observed that the agents encapsulated with liposomes prevent decomposition reactions that can occur with the effect of the external environment, thanks to the interruption of their interaction with the system they are in, and the controlled release of active agents into the environment can be realized, thus the encapsulated compounds such as antimicrobial, antioxidant, vitamins are more resistant to processes such as pasteurization, drying, cooking, frying.

Lyophilization / Freeze Drying

Lyophilization is the freeze-drying process of products. It is generally used for the dehydration of products without losing their basic properties. It is the process of freezing the product completely and sublimating the ice crystals formed under vacuum atmosphere. Since it is an application at low temperatures, it is a drying technique that provides dehydration without damaging the molecular and physical structure of the product. The lyophilization process is carried out in devices called Lyophilizer / Freeze Dryer. It is a preferred method for valuable products with high thermal sensitivity.

It preserves the shape, color and aromatic structure of the dried product.
It provides drying without damaging thermally sensitive products.
It provides numerous alternative preparation and drying opportunities for different product types and quantities.
It provides the opportunity to dry the product in the final product container.
Sterile drying facility is available.
It offers rapid dehydration.

Spray Dryer

Foods in liquid form are converted into powder form by using spray drying. The moisture is removed by spraying (atomizing) the feed into the hot dryer chamber. By spray drying, a spherical powder product with homogeneous particle size distribution is obtained. Drying time is shorter compared to other drying methods and this provides an advantage in drying temperature sensitive products. Spray drying is widely used in the food industry. This is because foods are sensitive to heat and consumers' interest in powdered products.

General Advantages of Spray Drying

It provides drying in a short time. It is important to carry out the drying process in a short time for drying temperature sensitive products. It can work at high capacities. It is low cost. It can be worked continuously systematically. It is easy to gain knowledge and facilitates the processing of new products.

Centrifugal Drying

It is basically a separation method. Using the centrifugal force obtained from the rotational movement, the particles in the sample are separated according to their shape, size and density. Centrifugal force is used for the separation of suspensions containing different densities in two or more phases, ie it can be used for liquid-liquid separation, liquid-liquid-solid separation or liquid-solid separation. It is equally effective in the separation of not only solids but also liquid mixtures.

Supercritical (CO2) Extraction

Supercritical fluid extraction is the process of separating the desired substance from any mixture by extraction with the help of a suitable solvent. The physico-chemical properties of supercritical fluids are between those of liquids and gases. This feature makes supercritical fluids a more effective solvent.

Carbon dioxide is the most preferred fluid/solvent in such processes due to its low critical temperature and pressure, non-flammable and non-toxic properties, and not harming the environment compared to other organic solvents. Supercritical fluid extraction is the most effective method for separation (extraction) and purification processes of heat sensitive compounds. When the extraction process is completed with supercritical fluids, the fluid can be easily separated from the solute by reducing the pressure.
