Freshly cut, young Alfalfa, naturally rich in proteins and grown in Northeastern France, is supplied to our extraction plants. The process involves a series of exclusively physical steps that most favourably preserve the intrinsic qualities of the plant. Result: a healthy and natural product that corresponds to the quality requirements of public health.
Throughout the process, the product is never exposed to synthetic solvents to facilitate extraction or to increase the pigment concentration.
1. Cold pressing
The alfalfa is gathered in several successive harvests from May to October. It is immediately shipped to the factory where the plant matter is fragmented to release its components. It is then pressed to furnish a green juice, rich in proteins and pigments.
2. Heating
The juice is heated to coagulate proteins. A preheating followed by the injection of steam flocculates the majority of proteins, that forms a coagulum. The product is stabilized by chilling at emergence from the dryer.
3. Centrifugation
The product from the above step is centrifuged to separate the coagulum from the liquid part. Pigments (lipophilic) present in the juice are carried with the paste from the protein coagulum.
4. Drying and granulation
The paste is dried on a fluidized air bed and granulated at sufficiently low temperatures to preserve the composition of the CAE.
The average extraction yield is about 7 %. It is improved by:
