A correct understanding of dietary fiber China's dietary fiber industry prospects

Many people, like me, have a lot of questions about dietary fiber. Because the parts included in dietary fiber are very complex, and the detection method used has not yet been standardized, its exact definition has not been determined. However, as the "seventh largest nutrient", the superior physiological efficacy and processing characteristics of dietary fiber are being paid more and more attention, so whether for ordinary consumers or production enterprises, it is necessary to correctly understand dietary fiber.is dietary fiber?1998
the American Grain Chemist Association (
AACC
) established a special committee on dietary fiber definition.

, 1999
84

AACC
Annual Meeting on Dietary Fiber The definition is discussed and finally defined as follows:dietary fiber refers to edible plant-based components, carbohydrates and similar substances that are resistant to digestion and absorption of the human small intestine and partially or completely fermented in the large intestine of the human body, including polysaccharose, oligosaccharies, lycope and related plant substances. Dietary fiber has one or more physiological functions, such as intestinal urination, regulation and control of blood sugar concentration, blood lipid reduction, etc.The definition given from
AACC
defines the main components of dietary fiber, which is an edible plant ingredient rather than an animal component, and the components of dietary fiber measured according to current analytical methods are broadly divided into the following categories:total Dietary fiber (
TDF
): Includes all parts such as non-
starch
polysaccharides, ligands, resistant starches (including regenerative and modified starch) and Merad reaction products.soluble dietary fiber (
SDF
): including hydrogels such as gels and some hexafiberin.insoluble dietary fiber (
IDF
): including cellulose, ligands and some hemiculose.Non-starch polysaccharides: After the starch is removed from food samples, residues are dissolved into neutral sugars with acid water, and then the sum is quantitatively detected with gas chromatography (
GLC
) or high-efficiency liquid chromatography (
HPLC
), i.e. non-starch polysaccharides, or by enzymatic methods, including cellulose, semiculose, fructose, and soluble non-fibrous polysaccharides.dietary fiber is coarse fiber?many people have misconceptions about dietary fiber, and even think that coarse fiber is dietary fiber. In fact, the term dietary fiber did not appear in nutrition until
1970-
, when only "coarse fiber" was used to describe indigestible, absorbed food residues, and only partial cellulose and tyrinin. It is generally believed that coarse fiber on the human body does not have a nutritional effect, and even eat more will affect the human body on food nutrients, especially the absorption of trace elements, adverse to the body, has not been paid attention to. Since then, through a series of investigations and studies, especially recently, it has been discovered and recognized that "non-nutritional" substances that cannot be digested and absorbed by the human body are closely related to human health and play an important role in preventing certain diseases of the human body, such as coronary heart disease, diabetes, colon cancer and constipation.Dietary fiber includes insoluble fiber and soluble fiber, coarse fiber taste poor, including most cellulose, part of hemglass and heminose, mainly insoluble fiber, water-soluble fiber taste better, the use is also relatively extensive. It should be said that coarse fiber is part of dietary fiber. Dietary fibers embody compounds that cannot be digested and absorbed; There are many ingredients, such as polysaccharies, that belong to dietary fiber, but not coarse fiber. Dietary fiber is a concept that comes from nutrition, emphasizing that the part cannot be digested and absorbed; The so-called coarse fiber multi-fingered woody, after ingestion will absorb water expansion, increase stool volume, stimulate intestinal peristalsis. Too much intake can cause dry stools, constipation, and excessive intake can hinder mineral absorption.prospect of China's dietary fiber industry?2005
, China's
nal food enterprises
in the international trend driven by the introduction of a lot of fiber-rich healthy food,
at the end of 2005
sales exceeded
50
billion yuan, but compared with Europe, the United States and Japan, the gap is very large!China has a population of 3 billion, in addition to the poor areas in the west, about
10
billion people should supplement dietary fiber, according to
6
grams per person per day, the annual need for
2.
2 million tons of dietary fiber. If you consider that there are about
,
women and more than
,
million elderly people in our country who suffer from constipation for a long time, another
36
million overweight or obese people,
1.66

million patients with hypertension,
1
70 million people with abnormal blood lipids, more than
97 million
people with diabetes, their special needs for dietary fiber, then the annual demand for dietary fiber is no less than
3 million tons
China's annual output of dietary fiber is now less than 10
10 million
of 10 million tons. Therefore, China's potential market for dietary fiber is very large, the market prospects are very broad, need to be developed.the development of dietary fiber market, enterprises should jointly form a joint force, starting from two aspects. First, enterprises jointly called on the government to include dietary fiber in the nutrition label of the basic nutrient range, and second, the joint implementation of dietary fiber science project, publicity, improve awareness of dietary fiber. china

2014
2nd China Dietary Fiber Industry Summit Forum will be held on

, beijing Jingrui Hot Springs International
Hotel
held, this forum not only includes the above two aspects of the purpose, but also will be the dietary fiber industry there are many questions to explore and seek solutions, including: dietary fiber standards, different types of dietary fiber how to develop different industry standards? How to solve the problem of the detection deviation of dietary fiber in the detection of dietary fiber? How is the purity of the extracted dietary fiber measured? At the same time, the Forum will invite
dairy
enterprises,
beverage
enterprises and
other food
enterprises, etc., to discuss the application of dietary fiber in the food industry. The Forum hopes to call on dietary fiber standard-setrs to improve the accuracy and operability of the standard and facilitate the development of the industry from the practical point of view of enterprise operation.
