High quality oat-beta-glucans with a large range of Mw and extremely Mw distrivution are available now!

Background
In 1998, the Food and Drug Administration (FDA) issued its final rule allowing health claims to be made on the labels of foods containing soluble fiber from whole oats (oat bran, oat flour and rolled oats), from that time, there have been an increasingly number of researchers to put effort in research, development and application of oats.

Current Research
Many researches demonstrated that Oat-beta-glucan is responsible for lowing cholesterol and protecting against the heart disease. And because beta-glucan is a main component of oats, it has an ability to enhance the digestion for humans. In the area of Health, it also has a putative immunomodulatory activity, which is commonly used in the natural cancer supplement. In the cosmetic domain, oat-beta-glucan is usually added into lotions and shampoos due to its repairability of skill cells, wrinkles reduction, protection against UV damage and hair strength improvement. Hence more researchers have focused on the development and application of oat-beta-glucan.

Challenges
However, so far it is little known about mechanisms for its currently clear functions. And the challenges we faced are four problems as followed:
1. Why OBG is bioactive?
2. How is bioactivity influenced by structure?
3. Which structural feature is truly significant for the bioactivity?
4. How OBG is modified to control and enhance the bioactivity?

Additionally, during the researches, there are usually controversial or inconsistent trial outcomes resulting in unconfirmed conclusions.

Difficulties and Solutions
How do we solve these problems? And what difficulties do we have to overcome? One of the difficulties in developing carbohydrate polymers is the heterogeneity of samples resulting from the quality and consistency of the products. That is why Putus is providing a great opportunity to revisit oat-beta-glucan.

Putus applied new techniques to provide OBG standards with variety of molecular weights and extremely narrow polydipersity, which are very important characteristics to govern both physical and practical applications and establish structure-bioactivity relationships.

Putus offers PS-OBG, a new carbohydrate polymer molecular weight (Mw) standards with Mw ranged from 10,000 to 1,400,000 and Mw distribution (MwD) of 1.01 to 1.05. Compared to the currently available polymer standards Pulullan and Dextran (Mw ranged from 5900 to 788,000), PS-OBG demonstrated a larger Mw range which facilitate the Mw measurement of very large polymers. Pullulan and Dextran are universally used as polymer standards because so far there is no commercially available beta-glucans that are comparable with Pullulan and Dextran with regards to the narrow Mw distribution. The PS-OBG produced by Putus demonstrated an extremely narrow MwD of 1.01-1.05. For the standards with Mw below 200,000, the MwD can reach 1.001-1.005.

What is more, Putus is also offering beta-glucans from barley and wheat as well as galactomannan with different branching ratio from Fenugreek (FNG), Guar (GG), Locust bean (LBG) and Tara (TG) of high qualities. To know more, visit and contact us by
