Red-heart Salted Egg

Last updated 2026-11-09 — Salted duck eggs, known as "Qingguo" (green fruit) due to their bluish-green shells and smooth, round appearance. Legend has it that during the Qing Dynasty, there were many workshops around the lakes producing preserved eggs and Qingguo (salted duck eggs), which were transported by land and water to the regions of Beijing, Tianjin, and Baoding. These products were highly favored in the markets, with some even exported overseas. Among them, the red-heart salted egg enjoys an especially long-standing reputation — it has a well-balanced salty taste, a fragrant aroma, and is considered an excellent calcium-rich food for summer. It can be stored at room temperature for up to 100 days. The highlight of this product is its red egg yolk and rich nutrition. It is high in fat, protein, and various amino acids essential to the human body. It also contains a variety of minerals such as calcium, phosphorus, and iron, along with essential trace elements and vitamins, all of which are more easily absorbed by the body. With a moderate level of saltiness, it is suitable for all ages.
