Gaoyou Salted Duck-egg Processing

Gaoyou salted duck eggs have a defined GI product boundary, while the local processing network also includes firms whose individual GI rights are not established here. A 2021 provincial approval list names Gaoyou Red Sun Foods and Gaoyou Lianmin Foods; 2025 sampling records show their cooked salted eggs or egg products. A 2024 State Post Bureau report also visits Lianmin's e-commerce packing operation. Local reporting describes Gaoyou Qinyou Egg Products making salted eggs and yolks, but this record does not claim Qinyou holds the GI emblem. The three are separate companies with roles in processing, online fulfilment and heritage-brand products. Older industry-value reports are not current company figures. Buyers should check egg origin, curing time, heat treatment, microbiology, package integrity, shelf life and the exact product covered by any GI mark.
