Detailed Introduction to Probiotics and Prebiotics
Posted by kiko on December 9th, 2020
It is generally believed that prebiotics provide "food" to probiotics, which can be decomposed and absorbed by beneficial bacteria in the intestines, and promote the growth and reproduction of beneficial bacteria. The familiar bifidus factor is a prebiotic that promotes the growth of bifidobacteria in the intestine.
Prebiotics are non-digestible food ingredients that can have a beneficial effect on the host by selectively stimulating the growth and activity of one or several bacteria, thereby improving the health of the host.
Synbiotics refer to preparations in which probiotics and prebiotics coexist and play a synergistic effect.
Types of prebiotics
Prebiotics mainly include various oligosaccharides or oligosaccharides (composed of 2 to 10 molecules of monosaccharides), and more generally, functional oligosaccharides.
Functional oligosaccharides include isomalt-oligosaccharides, galacto-oligosaccharides, fructooligosaccharides, lactulose oligosaccharides, lactulose, soybean oligosaccharides, xylo-oligosaccharides, palatinose, coupled fructose and the like. Among them, gentian oligosaccharides are not sweet but have a soft refreshing bitter taste, and the others all have varying degrees of sweetness, which can be used as a functional sweetener to replace or partially replace sucrose in food. So far, there are more than 1,000 kinds of functional oligosaccharides known, and only a few foods in nature contain natural functional oligosaccharides, such as onions, garlic, mango husk, asparagus, etc.
Prebiotics also include non-carbohydrate substances. In theory, any substance that can reduce harmful bacteria and promote the proliferation of healthy bacteria or increase beneficial metabolism can be called a prebiotic. Therefore, some organic acids and their salts, such as gluconic acid and calcium gluconate, and some Chinese herbal medicines such as ginseng, wolfberry, astragalus, etc. or tea extracts, can also act as prebiotics.
The role of prebiotics
Oligosaccharides are difficult to digest by the human body. At the same time, tooth decay, obesity, hyperlipidemia, diabetes, etc. are closely related to excessive sugar intake. The effect of this prebiotic is mainly reflected in helping to improve the intestinal flora. The main side effects of oligosaccharides are flatulence and bloating in people who are sensitive to oligosaccharides.
