Inulin, soluble dietary fiber "" pure inulin, prebiotics zero added two-way regulation "...... Search for inulin on the Internet, these dazzling product information is coming, natural, safe and other product characteristics are consistent with the current trend of people's pursuit of health. Inulin, one of the world's three recognized prebiotics, high-quality water-soluble dietary fiber, is currently the most promising gastrointestinal probiotics products. So, how does it regulate the intestinal microecology? What is the current market situation? How can it develop better in the future? The editor will take you to see what relevant people in the industry say.
Dual efficacy favored by consumers
Inulin, commonly known as inulin, is a reserve polysaccharide in plants. The degree of polymerization is between 2 and 60. It is a kind of natural fructan mixture composed of D-fructofuranose through β-2,1 glycosidic bond. It is mainly derived from plants and has been found to have more than 36000 kinds. Inulin, like starch, is an energy substance of organisms and is a very ideal functional food ingredient. It is also a good raw material for the production of fructooligosaccharides, polyfructose and other products. In nature, inulin is widely distributed. Plants that people eat daily, such as garlic, onion, green onion, banana, wheat, etc., contain inulin. Inulin has the dual effect of dietary fiber and prebiotics.
According to the Hong Kong Center for Food Safety, the world's inulin is currently divided according to the raw materials used, mainly chicory and Jerusalem artichoke. Europe basically uses chicory as raw material to produce inulin, China mainly grows Jerusalem artichoke, and most domestic producers use Jerusalem artichoke as raw material to produce inulin.
Inulin, in the international requirements of its water-soluble dietary fiber content is not less than 90%, China's national standard is not less than 86%. It has long been called the "seventh major nutrient" by the nutrition community-inulin, which is a dietary fiber, and has both prebiotic effects. Due to the lack of enzymes that decompose inulin in humans and animals, inulin is usually not absorbed by the stomach and small intestine after being ingested by the human body, but it will be fermented by bifidobacteria and lactic acid bacteria in the colon, thereby promoting intestinal probiotics Production, improve the intestinal microecological environment, so it is called an important bifidobacterium proliferation factor. Inulin is fermented and utilized by beneficial bacteria to produce short-chain fatty acids, which reduce the pH value in the intestine, thereby promoting the body's absorption of minerals and improving constipation. Before the end of the intestinal tract, inulin itself is fermented into short-chain fatty acids and lactate, depleting cholesterol in the body and inhibiting its use in the liver. Dirty inside the synthesis.
American scientists Yamashita had 18 patients with hyperlipidemia eat inulin for two weeks, 10 grams per day, the results found that total cholesterol decreased by 7.9, low-density lipoprotein cholesterol decreased by 10.4; for 4 weeks in 12 young healthy men daily Add 15 grams of inulin to the breakfast, total cholesterol decreased by 8.2, triglycerides dropped by 26%. Studies have found that long-term consumption of inulin is beneficial to reduce blood lipids, block the formation of cardiovascular disease channels, and prevent serious consequences such as coronary heart disease.
It is worth mentioning that due to the low sweetness of inulin, which is about 20% of sucrose, after the human body ingests inulin, it basically does not decompose or absorb through the oral cavity, stomach and small intestine, and only produces very little heat (about 6.28 kJ/g), which will not affect the blood sugar level. Therefore, inulin can be used as a new type of sweetener for diabetic patients, and is known as the new healthy glycogen in the 21st century. In addition, inulin can also replace fat. When it is completely mixed with water, it will form a creamy structure, which produces a smooth taste and full flavor, so it is deeply loved by consumers.
Prospects for organic certification trend is good
In view of the excellent probiotic properties of inulin, inulin has been widely used in dairy products, flour products and functional foods, which can improve the nutritional value and sensory characteristics of food, supplement dietary fiber needed by the human body, and reduce food calories. According to the survey data, inulin and its related products have become a considerable industry in Europe, while in China, there are only more than ten enterprises engaged in large-scale production of inulin, with an annual output of less than 100000 tons and an annual import of 200000 tons from abroad. The huge market gap makes the market potential of inulin very considerable.
The production of inulin in China is still a new industry, and the application of inulin is being vigorously promoted in beverage, health food and other industries. Nowadays, people's daily food is mainly composed of high-protein, high-fat, high-sugar and high-salt foods. The incidence of diabetes, high blood pressure and other diseases is rising rapidly. Eating a certain amount of inulin every day can play a certain preventive role. The probiotic function of inulin has been confirmed by a large number of scientific experiments. From the future development trend, inulin, a natural food ingredient with multiple functions, will have a broader development prospect. It is expected that the future inulin market will increase at an annual rate of 6.6%.
In recent years, the consumption boom of organic food is sweeping the world. It is gratifying that Jerusalem artichoke has good stress resistance and strong growth force, cold and drought tolerance, and can realize the production of organic inulin without fertilization and medicine. At present, the Jerusalem artichoke cultivation of Chongqing Jiaowang Natural Products Co., Ltd. has obtained the organic certification of NOP(The National Organic Program, National Organic Project) in the United States, and the inulin produced has also obtained the organic certification of NOP and EU in the United States. Yang Lichen, an engineer of the company, said that the production technology of inulin manufacturers in China is developing rapidly. As an enterprise, it should keep up with the hot spots of global health consumption and contribute to the human health industry.
According to Global Market Insights Inc. Data show that, driven by people's consumption awareness and regulatory regulations, global prebiotic sales in 2015 were $3.31 billion, and are expected to exceed $7.5 billion by 2023, with a compound annual growth rate of 11.6 per cent. In terms of sales volume, from 2016 to 2023, global prebiotic sales are expected to grow at a compound annual rate of more than 9%, with sales reaching 1.359 million tons. This indicates that inulin with prebiotic function will have great potential.
Standard first standard industry development
The research time of inulin in China is relatively short, and it has just started in the 1990 s. It was approved as a new food raw material in 2009, and its dosage and application scope are also limited. The new food raw material stipulates that the daily dosage of inulin does not exceed 15 grams and cannot be used in infant food. However, in the United States, inulin is recognized as GRAS(Generally Recognized as Safe) substance by the US Food and Drug Administration (FDA), and its scope of application is not limited.
In view of the new food raw material status of inulin, the consumption of inulin in China is still limited, coupled with the high price and the lack of promotion, so far, the total consumption of inulin in China is about 300000 tons, and its dairy products and health food are the main end users of inulin. It is reported that at present, there are mainly three companies in the world that produce inulin industrially, namely, Orafti of Belgium, Warcoing and Sensus, a subsidiary of Cosun Group in the Netherlands. Its total annual output accounts for more than 90% of the total output of inulin in the European Union.
How to further expand China's share in the world inulin market? Relevant experts pointed out that Chinese inulin production enterprises should first narrow the quality gap with imported inulin, increase domestic inulin exports, and improve inulin industry standards.
It is understood that from the perspective of market prospects, inulin, as a soluble dietary fiber, has been widely used in the fields of food and beverages, dietary supplements, health foods, and special medical foods. However, due to the lag in the formulation and revision of relevant product standards in my country, its market norms Development is restricted. Song Quanhou, vice president of the China Institute of Food and Fermentation Industry, said, "Inulin and other dietary fibers play an important role in controlling blood lipids, lowering blood sugar and regulating intestinal function, but the application of inulin in the food industry has not been effectively promoted. In order to make people eat healthier, the formulation and improvement of relevant standards urgently needs to be accelerated."
