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.
Tomato juice
Tomato juice was first served as a beverage in 1917 by Louis Perrin at the French Lick Springs Hotel in southern Indiana, when he ran out of orange juice and needed a quick substitute. His combination of squeezed tomatoes, sugar and his special sauce became an instant success as Chicago businessmen spread the word about the tomato juice cocktail.
