Cold-pressed juice
Cold-pressed juice refers to juice that uses a hydraulic press to extract juice from fruit and vegetables, as opposed to other methods such as centrifugal or single auger.
Hemp juice
The preferred procedure is to freeze the freshly cold-pressed juice instantly for preservation. The quality of the juice depends on immediate freezing. The frozen juice can be freeze-dried into a storable powder. Freezing and freeze-drying stabilize the natural form of the cannabinoids as cannabinoid-acids. Another procedure is pasteurization. The ultra-heat-treatment will "activate" the cannabinoids by separating the acid part from the natural cannabinoids. Increasing shelf life of hemp juice can also be achieved by fermentation, using various procedures, preferably by adding yeast/yeast extract and sugar. Using salt is a proven procedure to achieve storability in foods. With regard to hemp juice this can be done by mixing salt with fresh hemp juice, which leads to an easily usable product: "hemp salt".
