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.
Jif (lemon juice)
In the 1950s, Edward Hack had the idea of lemon juice being packaged inside lemon-shaped and coloured containers. Bill Pugh, an English plastics designer, created a prototype based upon Hack's concept. His company then produced and marketed Hax brand lemon juice in the plastic containers, using juice from Sicily. Stanley Wagner of Coldcrops, Ltd. also independently designed a very similar package, which was used for Realemon brand lemon juice, later renamed to ReaLem. An agreement between Hax and Coldcrops led to Hax leaving the lemon juice business, and Coldcrops acquiring the branding rights for ReaLem. Coldcrops was acquired by Reckitt and Colman in 1956, which rebranded the product as Jif.
