Daesang operates through two main pillars: a food business and a materials business, with food accounting for the large majority of revenue.
The food segment is centered on the comprehensive food brand Chungjungone, covering traditional fermented sauces such as Sunchang gochujang, Miwon seasonings, agricultural and marine food products, and frozen and convenience foods, while the kimchi brand Jongga sells kimchi and fresh foods such as tofu.
The materials segment consists of a starch and starch-syrup business with the largest domestic production capacity, plus a bio business producing MSG, nucleic acids, lysine, arginine and tryptophan.
Overseas, Indonesian and Vietnamese subsidiaries handle starch-syrup and food sales, while Netherlands-based Daesang Europe B.V. supplies Chungjungone and Jongga products along with amino acids such as lysine across Europe.
In the United States, the company expanded its local distribution network through the acquisition of food company Lucky Foods, and Germany-based Amino GmbH serves as a platform for higher value-added medical-grade materials.
Its meat distribution subsidiary Hyesung Provision partners with global packers including Cargill, JBS and NBP to supply chilled and frozen meat and processed meat products domestically.
The domestic lysine and starch-syrup markets are dominated by a small number of players—Daesang, CJ CheilJedang, Samyang Corp and Sajo CPK—giving a relatively stable competitive structure, though this oligopolistic position has recently drawn Korea Fair Trade Commission antitrust scrutiny.
At its March 2026 annual general meeting, Daesang added the acquisition, management, licensing and sale of intellectual property and other intangible assets to its business purposes, opening the door to brand- and patent-based new businesses.
