In response to consumers' growing interest in desserts, health foods, and convenience products, Aejuwon ventured into the Hongshi (sweet persimmon) smoothie business. Hongshi Smoothie is a delicious and nutritious dessert that meets consumer preferences. It's a natural food product made from sweet persimmon that preserves the authentic taste of the original ingredient without any added sugar or preservatives. Hongshi Smoothie is a wellnessoriented product, ideal for children's growth nutrition and to alleviate the effects of hangovers, with a vitamin C content ten times that of apples. In addition, it comes at an affordable price, ensuring accessibility for all, and its frozen format simplifies storage and consumption.

Sangju, located in North Gyeongsang Province, is known as South Korea's premier persimmon producer. For centuries, native persimmon trees have been cultivated in this area, producing persimmons and dried persimmons since well before the 15th century. Dried persimmons from Sangju have graced the tables of the royal court since the Joseon Dynasty. Every household in Sangju grows persimmon trees, and Aejuwon  specializes in dried persimmons and Hongshi Smoothie. In August 2010, they established a dried persimmon
factory, and in February 2016, they completed the construction of their Hongshi Smoothie factory.
This factory, which covers an area of 200 square meters, can produce up to 700,000 units. The HACCP-certified Hongshi Smoothie factory has two freezing rooms with a total area of approximately 120 square meters, firmly establishing Aejuwon as a reliable producer in the heart of Sangju, the top persimmon producing region.

Aejuwon's Hongshi Smoothie is an ideal choice because it is deliciously sweet, nutritious, and low in calories. With no added sugar or preservatives, it can be enjoyed as a smoothie when thawed or as ice cream when frozen. For a twist, it can be enjoyed as a Hongshi Latte by simply adding milk. It is also a versatile ingredient, making it an excellent jam substitute in various dishes, or even an ingredient in red pepper paste, using Hongshi instead of artificial sugar. Made entirely from domestically grown sweet persimmons, it contains 100kcal per
150ml, has no preservatives and must be stored at or below -18°C. It is safe to consume for up to 24 months from the date of manufacture. It contains 7% carbohydrates, 20% sugar and 1% protein, with zero fat, saturated fat, trans fat, cholesterol and sodium. Aejuwon's unique patented process ensures convenient packaging in a pouch containing pure sweet persimmon. Packaging options include 20, 30, 50 and 60 units.

The production process of Hongshi Smoothie involves thawing washed and peeled frozen sweet persimmons, a meticulous process that takes about 2-3 days. The sweet persimmon harvest season typically falls between late October and early November and lasts about 20 days each year. Actual production begins in early November with a daily capacity of 6,000 units. Operating for 20 days per month, Aejuwon can produce 12,000 units per month, or 144,000 units per year. The raw sweet persimmons and the finished smoothies are carefully stored at or below -20°C to maintain their quality. As Hongshi Smoothie is a product made entirely from persimmons, its production cost fluctuates based on the yield of persimmons. In June 2020, Aejuwon received HACCP certification for its persimmon washing and metal detection processes, underscoring its commitment to food safety. In addition, in April of the same year, they secured a patent for the "manufacturing method of frozen Hongshi smoothie." Notably, they also export their products to the Netherlands via Sangju City.
