Original title: Chinese Academy of Thermal Sciences has made important progress in the research of jackfruit polysaccharides regulating intestinal microbes and short-chain fatty acid production
Recently, the Chinese hot drink ASTRI Hong processed and Engineering Research team discovered pineapple honey pulp of biologically active polysaccharide has a regulating intestinal flora and promote intestinal micro- biological fermentation produces short-chain fatty acids and other intestinal prebiotic effect
Jackfruit is known as "Tropical Treasure" and "Queen of Tropical Fruits".
As a typical tropical fruit tree that integrates fruits, woody grains and precious materials, it is found in the tropical, tropical, and tropical areas of China, such as Hainan, Yunnan, Taiwan, Guangdong and Guangxi.
A large number of cultivation in subtropical regions
At present, the world's jackfruit planting area is about 4 million mu, with an annual output of more than 8 million tons
The current planting area of jackfruit in China is more than 500,000 mu, with an annual output of more than 1 million tons.
Hainan Province is the main production area of jackfruit in China, covering an area of more than 300,000 mu.
It has become one of the important ways for Hainan farmers to increase their economic income
In recent years, research in the field of jackfruit processing and functional evaluation has attracted more and more attention from researchers
The intestine is an important place for the body to digest, absorb and metabolize nutrients, and is colonized with hundreds of billions of intestinal microorganisms
Polysaccharides can be utilized by the intestinal flora, interact with intestinal microbes and selectively increase the number of beneficial microbes in the intestinal tract, and play its role in regulating intestinal health
The processing and engineering technology research team of Xiangyin Institute studied the regulation of jackfruit polysaccharides on the intestinal microbes of mice through metagenomics, and analyzed the short-chain fatty acids in the intestinal contents (including acetic acid, propionic acid, butyric acid, valeric acid, etc.
) ) Changes
The research results show that jackfruit polysaccharides can regulate the Bacteroidetes, Firmicutes, Proteobacteria, Cyanobacteria, Actinobacteria and Molliobacteria in the intestine.
(Tenericutes) and other intestinal flora
GC analysis results show that jackfruit polysaccharide can promote the production of short-chain fatty acids such as acetic acid, propionic acid and butyric acid in the intestine
The results of this study can provide a theoretical basis and scientific basis for the development and application of polysaccharide prebiotics
Related research results "Polysaccharide from Artocarpus heterophyllus Lam.
(jackfruit) pulp modulates gut microbiota composition and improves short-chain fatty acids production" were published in the TOP journal of the Chinese Academy of Sciences JCR "Food Chemistry" (IF=6.
