“I didn't expect that before we could eat the crayfish, the shrimp shells could also be used as chitin, but I didn't expect shrimp shells to be worth more than shrimp.†Qian Mu crayfish, Zhaonao Village, Xiongkou Town, Qianjiang City, Hubei Province At the breeding base, 48-year-old fish farmer Zhao Yuping said with rough and dark hands.
Qianjiang enjoys the reputation of “Hometown of Chinese Crayfish†and “The First City of Chinese Crayfish Processing and Exporting†and is currently the largest processing and export base of freshwater crayfish in China. In 2016, Qianjiang produced 450,000 mu of crayfish, produced 73,500 tons of output, and had a total output value of 18 billion yuan (RMB, the same below), with an export value of 150 million US dollars.
Tao Zhonghu, chief engineer of the Qianlong Lobster Industry Development Bureau, said that the edible portion of a crayfish is less than 20%. Therefore, about 80% of shrimp shells become waste in the traditional lobster processing and production process. More than 100,000 tons of shrimp shells are a waste of resources, but also pollute the environment.†Tao Zhonghu said.
In order to make crayfish shrimp shells “waste and treasureâ€, in 2007, Qianjiang Huashan Aquatic Food Co., Ltd. (hereinafter referred to as “Huashan Companyâ€) and Wuhan University jointly established the Chitin Engineering Technology Center and successfully extracted them from shrimp shells. Out of chitin, glucosamine hydrochloride and other products.
Tao Zhonghu introduced that chitin is a substance extracted from crustacean shells such as shrimps and crabs. It has a variety of physiological functions, and has anti-cancer and anti-cancer effects, tumor cell metastasis, and improves human immunity and liver detoxification. Widely used in food, medicine, health care and other fields.
In 2009, Huashan invested 415 million yuan to build a project to process 100,000 tons of waste shrimp shell extraction ammonia and shrimp fish processing resources, and successfully obtained the “Jian†number approval. “The company currently has an advanced chitin health product workshop with an output value of RMB 2 billion in 2016.†said Liu Shizheng, director of Huashan's office.
Tao Zhonghu said that chitin and other shrimp shell derivatives have very important development value and application value. The added value of these derivatives will be 10 to 100 times higher than the original, and the direct benefits of the expected value of conversion will exceed tens of billions yuan, and will be new. There are nearly 100,000 jobs added.
Prior to planting shrimp rice, Zhao Shuping had a net income of only 15,000 yuan per year. After Qianjiang promoted the “shrimp and rice co-production,†he transferred the land in his hands, and then passed the “return package†method to have the right to operate 20 acres of shrimp rice fields. Today, the annual income can reach 260,000 yuan. , nearly 20 times more than before.
Zhao Yuping told reporters that part of the crayfish he breeds will be shipped to the trading center and sold to shrimp dealers or restaurants, and the other part will be sold to Huashan for further processing. "Till July of this year, I had nearly 200,000 gross income, plus the late shrimp rice, this year has more than 260,000 yuan income." He said.
Crayfish collected from farmers, shrimp meat is processed into packaged foods such as shrimp balls and brine shrimps, sold throughout the country and exported to Europe and the United States. The rest of the shrimp shells are processed by Huashan Company and processed into derivatives such as chitin. And these are currently required to be completed manually.
“The work of manually peeling the shrimp is a bit difficult, but the working environment is good and the wages are good.†Worker Li Yong, who is nearly five years old, said that when the crayfish was “off seasonâ€, he would farm at home and he would come at other times. Huashan company and other aquatic products processing enterprises do stripping shrimp workers, the monthly salary is about 6,000 yuan.
According to Liu Shih-chieh, the buzz of catering makes the market for crayfish bullish, and 50 kilos of crayfish can only produce 1 jin of chitin. Therefore, according to the current market price, the price of 1 metric tons of chitin is 100,000 yuan, and it is generally exported. To Europe and the United States. Therefore, the wages of workers are naturally not low.
“Qianjiang will spend 5 to 10 years to build a chitin deep-processing industry cluster with an output value of 22 billion yuan. It will transform the crayfish industry from traditional agricultural product processing to the biological high-tech industry, and build it into a chitin industry in China and the world. All '." Qianjiang Municipal Party Committee Secretary Huang Jianxiong said.
