Freeze-drying (lyophilization) is a special process where frozen raw materials (fruits, vegetables, puree, concentrates) are placed in a refrigerated vacuum and ice crystals in the product are sublimated into water vapor. Thanks to high vacuum conditions and low temperature during the process the cell structure of the original raw material remains intact.
This keeps the original form of food, preserves consistency and nutritional value as opposed to air-dried food products.
VACUUM BELT-DRYING
The continuous vacuum belt dries high viscosity liquids or pasty raw material that is difficult to process by spray drying type at low temperatures and produce the highly soluble dried products in comparatively short time. Required dry matter of final products is regulated by adjustable parameters such as feeding volume, conveying velocity, temperature and pressure. Recommended for heat-sensitive liquid raw materials.
SPRAY-DRYING
The spray drying technology consists of spraying a liquid raw material (fruit or vegetable concentrates, soft extracts) into thin droplets in a chamber where warm air is brought. The water contained in the liquid is instantly evaporated and finally, we get thin powders. Product after dilution in water, regain most of the input material characteristics. Recommended for instant products where powder properties such as good flowability, dispersibility and visual appearance are key parameters.
EXTRACTION
It is a method of separating liquid or solid mixtures with a liquid solvent. The solvents include water (aqueous extraction), methanol, ethanol, ethyl acetate or hexane and others (solvent extraction). The process involves extraction, distillation, concentration, drying and standardization.
All process is designed to give a high recovery of herbal extracts using optimum solvents levels, lesser extraction time, lesser distillation and concentration time. The extracts have intact phytonutrients with high concentrations of phytochemicals in the extracts. Extracts can be produced from leaves, flowers, roots or fruits of plants.
