Ledu Purple Garlic Growing and Black-Garlic Processing

Ledu purple garlic has a defined protected area, but growing bulbs, handling garlic shoots and making black garlic are different businesses. The national IP authority's 2026 mark-user list separately names Haidong Ledu Shengou Garlic Cooperative and Haidong Ledu Yongxiang Garlic-Shoot Cooperative, with different registration codes. Field reporting describes Shengou's growing and sales and Yongxiang's growing, storage and marketing. Qinghai Hong'en Technology was reported in 2021 as purchasing local garlic and processing black garlic; that dated account does not establish its current output or permission to use the mark. The existing province-wide cool-vegetable export entry concerns mixed fresh vegetables, whereas this entry is confined to Ledu garlic. Buyers should check origin and harvest lots for fresh bulbs, plus ingredients, processing dates and food licences for black garlic; older selenium and green-food claims are not a substitute for current tests.
