Sunnyday exports kimchi seasoning in convenient, small blocks. The product is designed to assist international customers with no prior familiarity with kimchi culture in making their own kimchi. The Kimchi Sunseng Cube is made entirely from Korean agricultural products. The production process involves creating a liquid seasoning, aging it at low temperatures, freezing it at -30°C, and then removing moisture through freeze-drying. The seasoning includes 15 ingredients: red pepper powder, radish, ginger, garlic, green onion, onion, sea salt, anchovy sauce, kelp extract, and glutinous rice paste. Each cube weighs 42 grams (90 kcal).
Making kimchi can be challenging, even for those who are already familiar with it. Once the salting stage is complete, the next step is to prepare the seasoning for flavor and fermentation using a variety of techniques and ingredients, including red pepper powder and anchovy sauce. The key to successful kimchi-making lies in the careful combination of these ingredients. Sunnyday has developed a convenient product that streamlines this complex process: the Kimchi Sunseng Cube. This innovation makes it simple for anyone, anywhere, to create kimchi with minimal effort.

To use the Kimchi Sunseng Cube, simply dissolve one cube in a paper cup of water. In just five minutes, you will have a kimchi seasoning paste ready for use. Mix the paste with the main ingredients, such as cabbage or radish, and allow it to mature at a low temperature. During the fermentation process, the flavor develops and the beneficial kimchi bacteria become highly active. After making kimchi with the Kimchi Sunseng Cube, there will be 100 to 200 million kimchi per gram of kimchi two days later. The growth of these bacteria peaks between two to three weeks after preparation.

The Kimchi Sunseng Cube is a highly versatile product that can be used to make a variety of dishes, including radish kimchi, bean sprout salad, and cucumber salad. The product is available in two versions: the traditional seasoning, which includes anchovy sauce and salted fish, and a vegan version that omits these ingredients. One cube is sufficient to season a standard-sized kimchi cabbage. The product is shelf-stable with a 36-month shelf life and meets all domestic certifications and international standards, including HACCP, HALAL, ISO 2000, VEGAN, and FDA. It was honored with the Food Week Excellence Award at the 2022 Seoul International Food Exhibition.

Videos illustrating the use of the Kimchi Sunseng Cube are available for viewing on Sunnyday’s website and YouTube channel. The product’s effectiveness was demonstrated at its first overseas exhibition in Paris in 2023, where all 210 units were sold within the first two hours. Despite the price of KRW 14,000 per box, visitors who watched the video were quick to purchase without additional questions. Interestingly, the traditional version with anchovy sauce and fish was the clear preference among visitors at the exhibition, with a popularity ratio of 7:3 or 8:2 compared to the vegan version.

Sunnyday began developing the concept of freeze-dried kimchi blocks in 2020. In December 2021, the company launched a kimchi block product using pre-made seasoning from a kimchi factory. To guarantee the distinctiveness of their offering, they unveiled the Kimchi Sunseng Cube with an innovative formula in June 2022. Within a month of its launch, the product was listed on the U.S. Amazon online store. In less than two years, export channels were established to over ten countries. The response from European markets has been exceptionally positive, with growing popularity in regions further from Korea, including the UK, Germany, France, Uzbekistan, the USA, Peru, Ecuador, Australia, Hong Kong, Vietnam, and Singapore. In addition, they intend to expand into Amazon markets in Germany and the United Kingdom in the near future. In 2023 alone, they exported approximately USD 60,000 worth of products to these countries, representing half of their total revenue for the previous year.
