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.
Juice
Juice bars share some of the characteristics of a coffeehouse, a soda fountain, a café, and a snack bar, such as providing blended drinks and light food. Juice bars may be standalone businesses in cities, or located at gyms, along commuter areas, near lunch time areas, at beaches, and at tourist attractions. In Mexico, juice bars have become more popular in the 2000s. Mexican juice bars often also sell healthy beverages and snacks.Groups of grape pits dated to 8000 BCE show early evidence of juice production; although it is thought that the grapes may have been alternatively used to produce wine. One of the first regularly produced juices was lemonade, appearing in 16th-century Italy, as an import, after its conception in the Middle East. Orange juice originated in the 17th century. In the 18th century, James Lind linked citrus fruits to the prevention of scurvy, which, a century later, led to the implementation of the Merchant Shipping Act of 1867, requiring all Ocean-bound British ships to carry citrus-based juice on board.
