CHINA King Oyster, By Roel Dreve
Raw materials stacked outside.
Accompanied by my able translator Iris Chen, working as a volunteer for the Mushroom Days, we first made our way to Fujian Jiatian Agricultural Development Co.,Ltd., not far from Zhangzhou, neighbouring the special economic zone (Xiamen). Here, in the Jingc- heng Mushroom zone in Nanjing county, we received a friendly welcome by General Manager Rongchi Wang and vice manager and chief technician Jiajin Yang. Fujian Jiatian was founded in 1993 and has been at the forefront of industrialised agricultural development in the region, and the research and promotion of edible fungi ever since, working closely with governmental and (organic) certification organisations, and coopera- ting with Taiwan’s agricultural sector. It has a registered capital of 6 million US Dollars and covers an area round 13 hectares. Jiatian produces several fresh and dried mushrooms; white back black fungus, mini oyster mushrooms, abalone mushrooms (Pleurotus cystidio- sus) among others. Some are processed into seasoning products and mushroom snacks and extracts. By far the core activity of the company however, is the production of King oyster mushrooms on a gigantic scale.
120.000 bottles per day Based on industrialised bottle production, Fujian Jiatian has built a new, large-scale automated and totally enclosed hygienic (no insects, no pests, no chemicals) factory for Pleurotus erengyii in two stages. The first of which is 3000 m2, the second 4500 m2, with a total capacity of 3.6 million bottles in 126 growing rooms (20.000 bottles per room). Total production amounts to 120.000 bottles per day, 39 million per year. Different raw materials are used; saw dust, corn cob, wheat bran, corn flour etc. The managers showed us the whole pro- duction process, from mixing the raw materials, filling the bottles, sterilization, cooling, inoculating, spawning, scratching, growing, harvesting, cooling and packa- ging. The company uses both solid and liquid spawn. According to the managers, liquid spawn has a few advantages; the mycelium growing speed is very high, the contamination rate is low and the fruiting bodies are consistent. The King oyster mushrooms produced have small fruiting bodies, the caps are a little black and thick, the mushroom is dense and has optimal fla- vor. The end product looked very well indeed and the
Kingsize Company
During the 7th Chinese Mushroom Days, I had the chance to visit some of the best and largest mushroom growing operations in Fujian on November 19th, one of which produces King oyster on a very big scale.
Liquid spawn is used at Fujian Jiatian.
