2results about How to "Reduce pectin content" patented technology

The invention relates to a leaf-moistening and re-drying method for reducing the pectin content of flue-cured tobacco and a product thereof, and the method comprises the following steps: detecting the initial pectin content in tobacco leaf raw materials, and then treating by adopting a specific leaf-moistening and re-drying process according to the tobacco leaf raw materials with different pectin contents, so that the pectin content in the flue-cured tobacco product is remarkably reduced, and the yield of the flue-cured tobacco product is improved. The method effectively reduces offensive odor substances in the flue-cured tobacco product, reduces loss of aroma substances in tobacco flakes, improves the content of aroma components, softens smoke, reduces irritation, improves smoking comfort, remarkably improves the quality of the flue-cured tobacco product, and has important significance in improving the processing level of tobacco leaf raw materials and the application value of the product.

A strain of *Aureobacterium wanduense* producing pectinase and its applications, characterized in that: the strain is named 159, and its classification is named... Chryseobacterium wanjuense The specimen, with accession number CGMCC No. 37744, is deposited at the China General Microbiological Culture Collection Center. This invention also provides its optimized culture method and application technology for pectin degradation in aged tobacco, addressing the problems of low pectin degradation efficiency and lack of specific functional strains in existing tobacco aging processes. Compared with existing technologies, this invention has the following outstanding advantages: it is the first to screen and verify the ability of *Aureobacterium wanduense* strain 159 to efficiently degrade pectin in aged tobacco, expanding the application scope of *Aureobacterium* in tobacco processing and providing the tobacco industry with a novel microbial resource and green processing technology.
