Woodeumgee Farm Corporation has successfully mass-produced Korea's first stevia tomato, "Tomango", and established a smart farming system to produce the tomato. The company produces and distributes tomatoes grown in its self-developed semi-enclosed glass greenhouse. In 2021, the company exported about 300 tons of smart farm tomatoes to Japan, and supplied samples to Hong Kong, Singapore, and the United Arab Emirates. The area used for cultivation is 11 hectares, the size of 13 soccer fields. In 2020, the company's sales amounted to KRW 23 billion, and in 2021, sales doubled to KRW 48 billion, while operating income amounted to KRW 10 billion. The company focused on expanding and investing in its facilities in 2022, and the sales reached KRW 45 billion with a slightly decreased operating income of KRW 4 billion. This year, the company expects sales of KRW 60 billion and operating income of KRW 9.5 billion. Recently, the company is set to be listed on the KOSDAQ market.

Consumers already knew that tomatoes are good for their health, but they did not eat them often because they were not as sweet as they'd expect. Woodeumgee Farm introduced a technology using stevia, a natural sweetener approved by the U.S. FDA and used to increase the sugar content of apples. Introducing the technology was not easy. They had to throw away 500 kilograms of tomatoes every day during the trial. Despite these failures, the company continued to research and work to develop the original technology. A new way to evenly diffuse stevia in tomatoes using ultrasonic waves for post-harvest processing and immersion was invented, which led to three patents. They named the product "Tomango" because it is as sweet as mangoes. All of the stevia added for sweetness is excreted through urine.
The production process of Tomango involves the sorting of the grown tomatoes by size and ripeness, followed by a primary cleaning. The quality is determined by this step. Of course, the right recipe is just as important. After the primary cleaning, the raw material is treated with stevia and then dried after a second cleaning. The product is then packed and wrapped before shipping. The sweetness of this product is around 20 Brix, but the actual sugar content is very low, around 5 Brix, making it ideal for health and diet. Tomango has been the main product of Woodeumgee Farm's growth, accounting for more than 80% of the company's total sales. The company processes and produces Tomango from its own tomatoes and tomatoes sourced from more than 200 cooperating farms, and the product is sold nationwide. Tomango is so popular that the demand for it outruns the supply.

Woodeumgee Farm successfully built Korea's first 1.9-hectare state-of-the-art semi-enclosed greenhouse in 2019. Currently, the company produces jujube cherry tomatoes, ripe tomatoes, etc. throughout the year in a smart farm facility of about 3.5 hectares. In 2022, the company invested in HACCP facilities and built an automated sorting facility at the second factory to grow European vegetables on about 3.6 hectares. Woodeumgee invested KRW 2 billion to install LED lighting in the greenhouse. It is now possible to grow vegetables in all four seasons without worrying about lack of sunlight, even in cloudy days, rainy seasons and winter. Thanks to information technology, it is easy to control the temperature, humidity and amount of light to provide the best conditions for the plants to grow. This has increased the plant's growth capacity by 25% and doubled the Tomango production from 40 tons to over 80 tons per day.

Tomango boasts world-class quality. The company has laid the foundation for market development both at home and abroad. In Korea, Tomango is distributed through NC Department Store, Kim's Club in Eland, Lotte Mart, E-Mart 24, Mini Stop, Coupang, etc. In January, the company participated in the Korea-UAE business mission. The local response to Woodeumgee Farm and its flagship product Tomango and the construction of smart farms has been positive. Discussions have begun to export to countries in the Middle East and Southeast Asia, as well as Saipan, Hong Kong and Singapore. The company also signed an MOU with the United Arab Emirates to export its proprietary semi-enclosed glass greenhouse.
