The coverage of a Delia Foods factory, a Kewpie subsidiary, introduced the use of manufacturing know-how, including the selection of potato varieties and timing, to improve potato salad.
Staff guided a tour of the Delia Foods factory in Akishima, Tokyo, showing a work area where bags filled with potatoes were neatly lined up.
At the production site, the selection of which potato varieties to use and when is regarded as important know-how directly linked to the quality of the potato salad.
In another room, employees were shown manually trimming potato sprouts as the potatoes moved along a conveyor belt.
Delia Foods is a Kewpie-affiliated company and was introduced as part of a business that holds the leading market share in the potato salad sector.
