L-Rhamnose (Rham, Rhamnose) is a naturally occurring deoxy sugar. It is commonly bound to other sugars in nature and exists in many plants. Most of suppliers extract the L-Rhamnose from some special plants, usually the sophora flower. Their products are commonly light yellow in color and sometimes low purity. Moreover, the production capability is limited for the uncontrollable factors in planting.

Zhejiang Shengda Zijin Biotech Co., Ltd. manufactures the L-Rhamnose by a new technology of natural biotech fermentation, and we possess the invention patents of fermentation, separation, purification and application for L-Rhamnose, which were developed by fermentation experts, few manufacturers are able to produce L-Rhamnose by fermentation on this planet. Meanwhile, our producer Zhejiang Silver Elephant Bio-engineering Co.,Ltd. (another subsidiary of Shengda Bio-pharm, stock code: 603079) whom has rich experience and proven technology in Biotransformation and fermentation separation & purification system. So far, we are the very sole mass producer of high quality L-Rhamnose by fermentation in China.

Advantages:

1. Higher quality, less heavy metal ions and pesticide residues by fermentation than extraction.

2. Less allergenicity, suitable for cosmetic addition.

3. Large production capacity since fermentation does not rely on season, or other planting conditions.

4. This production is bio-based, low-carbon and sustainable developing.
