Longpai Preserved Duck Egg

Last updated 2026-11-10 — The soft-shelled preserved duck egg from Pinghu has a history of over 250 years and is a unique product in the world, standing out as an outstanding and excellent local specialty of China. During the Qing Dynasty, Pinghu preserved eggs were listed as tribute items and exported to Southeast Asia. Over its long history, before liberation, it won international awards three times, and since the 1980s, it has received more than ten provincial and ministerial-level quality recognitions. It is truly a rare and delightful delicacy. The soft-shelled preserved duck egg from Pinghu is made by cracking fresh duck eggs and preserving them in high-quality glutinous rice mash. The shells are soft, the shape of the eggs is full and plump, the texture is tender, and the flavor is rich and aromatic with a long-lasting aftertaste. During the preservation process, the content of amino acids and soluble sugars increases, giving the preserved eggs their sweet and delicious taste along with easy digestibility. As fresh duck eggs are preserved in the mash, alcohols, sugars, organic acids, and salt from the fermenting rice gradually seep into the eggs, triggering a series of physical and chemical reactions. The proteins in the egg white and yolk gradually denature and coagulate under the prolonged effect of alcohol and organic acids, producing fragrant lipid compounds. The sugars and salt in the mash not only give the preserved eggs a pleasantly balanced savory taste but also dehydrate the yolk, making it crumbly and oily. They are not only delicious to eat, but when served as a side dish, they offer a more distinctive flavor compared to century eggs, with a strong aroma of wine, a well-balanced saltiness, and a delicious taste that lingers after eating. Pinghu preserved duck eggs are rich in nutrition, containing all 18 essential amino acids required for human metabolism. Regular consumption can promote growth and development, sustain vitality, and is especially beneficial for fetal development in pregnant women. Practical experience has shown that Pinghu preserved duck eggs have various benefits, including stimulating appetite, aiding digestion, and improving blood circulation. (Pinghu)
