Seaweed helps Qingdao’s marine economy stay afloat


[CGTN]
6/14/2018


What do beer, sausages, ice cream, facial masks, and toothpaste have in common? To the undiscerning eye, they're the bare essentials for any pajama party. But for those familiar with the "blue economy" of Qingdao, the link is crystal clear: seaweed.

In the coastal Chinese city, facing the Yellow Sea, aquaculture is a flourishing industry – and seaweed is the catch of the day, every day. But beyond a small circle of chefs, botanists, and chemists, few are interested in the plant whose all-too-familiar pungent "rotten egg" smell puts beachgoers and swimmers off, and even fewer are aware of its economic significance.

China's appetite for the "grass of the sea" dates as far back as the sixth century, and as a rich source of calcium, iodine, iron and vitamins A, C, B and E, seaweeds have cemented their place as an invaluable ingredient in kitchens and food factories.

China's crave for kelp

Estimates by market research firm Global Market Insights put the per capita consumption of seaweed in China at up to 2.5 kilograms annually – one of the highest in the world.

The acquired taste for the aquatic plant has placed China at the heart of a multi-billion-dollar industry, whose growth was boosted thanks to a burgeoning global demand as more health-conscious people introduce algae to their diets.

Global seaweed production more than doubled between the 2000-2014 period to reach a total of 27.31 million tons (in wet weight), according to the Food and Agriculture Organization (FAO). China is the world's largest algae producer, accounting for nearly 58 percent of the global output, and tops the list of the biggest seaweed import markets.

But seaweed is more than a nutritious addition to tofu soup, a crunchy salad topping and an indispensable ingredient for sushi. Its active substances have also caught the attention of a sprawling range of industrial sectors – from papermaking and textiles to cosmetics and pharmaceuticals.

"When we talk about seaweed, we always think of kelp, wakame or nori. But actually, seaweed appears everywhere," Jiang Jinju, a researcher at China’s State Key Laboratory of Bioactive Seaweed Substances, told CGTN.

Jiang's work centers on exploring the different ways algae can be exploited in the food industry and beyond.

"The reason seaweed has such a wide range of applications in the food industry is because of sodium alginate," the researcher noted.

The industrial importance of seaweed comes from its biological structure.

The long chains of polysaccharides (molecules consisting of a number of sugar units) in the cell walls of seaweeds not only allow the plant to adapt to the movements of water in its habitat but also make it industrially interesting.

More than chemistry

Alginate is one of the derivatives of these polysaccharides, also known as hydrocolloids, and possesses viscous properties, which makes it ideal as a thickening agent.

"This feature is especially useful in yogurt, beer and other beverages," pointed Jiang.

Under other physiological conditions, alginate can also form gels, making it handy in the making of sausages, canned meat, and jelly, as well as a useful component in edible packaging and food coating processes.

The laboratory where Jiang probes commercial prospects of algae belongs to Bright Moon Seaweed Group, the largest manufacturer of alginates in the world, with an annual output of 16,000 metric tons, accounting for 30 percent of global production.

The Qingdao-based company is contributing to the thriving hydrocolloid segment of the seaweed processing industry, which in 2013 was worth 1.2 billion US dollars, according to the World Bank Group, driven by a widening scope of commercial utility of seaweed extracts.

These derivatives are ideal biomaterials in masks, moisturizers, and make-ups; textile dyes; paper products; animal feed and pet food. They can be included in fabrics for eco-friendly sustainable clothing; and used as fertilizers to enhance the resistance of crops to fungi and insects.

The same advantageous properties that make seaweed extracts an asset in soap and sauce making allow them to be of great use in the pharmaceutical field.

Their high absorbency, adsorption, and gelling characteristics have given seaweed a medical value, with alginate gauzes and sticking plasters providing a breathable, moist alternative to traditional sterile dressings, accelerating wound healing and alleviating pain.

Seaweed compresses "can rapidly stop the bleeding, and won't cause damage when changing the wound dressing," Jiang stressed.

Shoring up China's ‘blue economy'

The versatility of seaweed and its contribution to a raft of industries are expected to continue driving demand.

The global commercial market of processed algae stood at 10.31 billion US dollars in 2015, according to Grand View Research. The San Francisco-based business consulting firm predicts a compound annual growth rate of 8.9 percent from 2016 to 2024 when the market value would reach 22.13 billion US dollars.

China, whose long-lasting taste for seaweed nurtured an advanced scientific expertise in its cultivation and industrialization, has been riding the wave of positive outlook of the algae industry.

The State Council approved in 2011 a development plan in the eastern province of Shandong with the aim of tapping into the area's bountiful sea resources. The "blue economic zone" was a lifeline for marine industries, and seaweed became a buoy to the local economy.

For Qingdao, one of the most important central city of Shandong Province and a city with a meandering coastline spanning 800 km, the blueprint presented an ocean of opportunities.

Local authorities invested in a series of projects to build on the city's historical strengths in shipbuilding, marine equipment manufacturing, and fisheries, and improve its marine chemical industry, ocean transportation, and seaweed processing sectors.

Efforts to modernize the city's industrial chain and billions of yuan invested in hundreds of projects and key enterprises seem to have paid off.

Oceanic industries accounted for over a quarter of Qingdao's GDP in 2016 – the year the city joined the elite "trillion-yuan club," up over 220 percent from 2012, when the marine economy generated some 110 billion yuan.

China, already the main exporter of refined hydrocolloids in the world, is projected to continue leading production activities of alginates through 2024, along with India, and power demand for seaweed production, according to Global Market Insights.

The humble seaweed has gone from being a staple on dining tables to a mainstay of Qingdao’s economy, working its way up from the bottom of the sea to the top of the industrial value chain.

朱易 : 馬鞍峰教會的增長及其深遠影響 (1) 
許多前來參加每年一次牧師研討會的牧師感到(2003年人數達到二十五萬之多),他們正經歷著一場由華理克牧師主導的改革運動,他們好像又回到了激動人心的馬丁路德改教運動的時代,不同的是他們可以與領導今天這場改革的領袖相遇和交談。

華理克牧師認為馬丁路德時代的改革是讓教會清楚教會所相信的是什麼,這也是我們今天還在傳講的資訊和教義,而今天的改革是讓教會清楚教會要做什麼


第二次宗教改革的呼聲 
新興教會的運動是教會的第二次宗教改革, 它將徹底改寫教會歷史, 並開創全新的教會時代.

朱易 : 馬鞍峰教會的增長模式和教會市場法的危機 (1) 
除了“目標導向”的增長公式,許多牧師認為華理克牧師還有增長的秘訣,但華理克牧師認為他的增長策略其實是十分簡單,歸納起來只有三條.

不少學者持懷疑的態度, 他們認為“目標導向”不過是將傳統的基督教原則作了不同的包裝。




《断背山》风头正健,价值观江河日下 (1) 
对基督徒而言,这部影片只不过是一个用艺术包装起来的同性恋合理的说教。但这一次,基督徒却无法用忽略它的存在的方式来反击它,他们必须寻找新的方法来坚守传统的战线。


朱易: 他的正面思維影響了全世界 (1) 
但是斯凱勒在教會界配受尊重,除了他在教堂的建造上獨樹一幟外,他的人品和神學上也頗為出色。他是少數幾個沒有醜聞的電視布道家之一,而讓他成為非主流教會和許多基督徒仿效的對象的原因是,他的講道著重正面信息,用正面思維看問題。
