Freezing Green Apples

The fruits are neatly cylindrical with regular and plump shapes, boasting a fruit shape index of 0.90, which gives them extremely high recognizability. The average weight of a single fruit is about 296 grams, with a uniform fruit diameter of ≥ 7 cm. The thick and sturdy fruit stems ensure excellent storage and transportation performance, with the transportation loss rate far lower than that of ordinary varieties. The peel is thin, smooth and rust-free, presenting a bright yellowish-green color and covered with a layer of natural fruit wax that endows it with a soft, gentle luster. Free from obvious blemishes, the overall appearance is fresh and elegant, perfectly catering to the aesthetic demands of high-end markets.

The flesh is crisp, tender and firm, bursting with abundant juice with every bite. There is almost no rough texture from the peel, making it more flavorful when eaten with the peel on. The soluble solids content reaches 16%–17.48%, with the sugar content stably maintained at 16–17 Brix and titratable acid content only 0.30%–0.32%, resulting in an ideal balance of sweet and sour flavors. Rich in 68 types of aromatic substances, it exudes a strong natural fruity aroma, mixed with a faint osmanthus and honey fragrance that lingers on the palate. The flavor becomes even more refreshing and mellow after refrigeration.

It is rich in vitamin C, dietary fiber, and various minerals including potassium and zinc. Each 100 grams of flesh contains 6.82 milligrams of vitamin C, and the dietary fiber helps promote intestinal health. The variety exhibits outstanding stress resistance, with significant tolerance to diseases such as Alternaria blotch and anthracnose, along with wide adaptability that ensures robust and high-quality growth. It also has excellent storage and transportation properties: the weight loss rate is only 1.22% after 120 days of storage at 0℃, and it can maintain its crisp texture even when kept at room temperature for two weeks, fully meeting the requirements of cross-border cold chain logistics.

As a late-maturing variety, the fruit development period lasts more than 180 days. After harvesting, the fruits undergo standardized procedures including pre-cooling, grading and sorting. Dwarf dense planting cultivation and Internet of Things (IoT) monitoring technology are adopted to achieve full-process control from pollination, water and fertilizer management to harvesting and storage. The storage period in controlled atmosphere (CA) warehouses can exceed 4 months, enabling year-round stable supply and ensuring consistent availability for overseas markets.
