Cold-pressed juice
Making cold-pressed juice is a two-step process. The first stage is to shred the fruits and vegetables into a pulp. Typically the shredding process uses a steel rotating disc. Produce is loaded into a large hopper feeding tube and typically falls into a filter bag. The second process is the hydraulic press; this exposes the shredded produce to extreme pressures between two plates. The pressure causes the juice and water content from the produce to drip into a collection tray below, leaving behind the fibre content in the filter bag. The fibre left behind is generally composted, recycled in food products or discarded.
Hemp juice
Hemp juice can be clearly distinguished from other liquid products of the hemp plant. Hemp milk and hemp oil, just like soy milk, are produced from the seeds of the plant. Beverages such as hemp beer use the dried flowers or dried leaves of the plant. When dried parts of hemp are used in water and extract results. Water extraction only contains a proportion of about 10% of hemp ingredients otherwise found in cold-pressed juice. Therefore, cold-pressed hemp juice contains a much higher percentage of valuable ingredients. More importantly, water extraction does not contain any of the important cannabinoids as they cling to the fatty acids of the plant, which are not dissolved in water extraction. Yet, cold-pressed hemp juice does contain the valuable cannabinoids.
These valuable ingredients are also preserved when hemp is juiced in a conventional home blender. This process of juicing is not suitable for industrial hemp because the plant fibers used for industrial applications are too hard to digest for humans.
