This research was done through collaboration with Kobe University and reported in the joint conference of 8th Asian Cyclodextrin Conference and 32th Cyclodextrin Symposium (Kumamoto, May 14~16, 2015).
Our company has an attract attention technology in functional food and personal care fields which raises the water solubility, stability and bioavailability of functional ingredients by using the inclusion property of cyclodextrin (CD).
Because of its high water solubility and non-digestible property, αCD can be taken as a water-soluble dietary fiber. Indeed, daily feed intake of αCD shows some anti-metabolic syndrome effects, improvements of the intestinal environment and anti-allergy effect. We also reported some interesting results supporting those effects (* please refer to the newest result of research "16th", "42th", "44th" and "50th" of our homepage for details.).
In this study, we report a new knowledge of αCD function on the mechanism of selective decreasing effect on serum saturated fatty acids by αCD supplementation.
Functions of αCD (human trial)
Selective decreasing effect on serum saturated fatty acids by αCD supplementation.
The effects of αCD to solubilities of fatty acids in fed-state simulated intestinal fluid (FeSSIF) were explored.
Result 1 Precipitation effect of αCD from the FeSSIF including fatty acid.
The precipitate was generated from the sample containing fatty acid and αCD.
Result 2 Decreasing effects of αCD on the fatty acid solubility (saturated vs unsaturated)
αCD decreased the solubility of saturated fatty acid (C18:0) more effectively than that of unsaturated fatty acids (cis-C18:1, C18:2).
It is well known that absorption of fatty acids is achieved by dissolving in the small intestinal fluid.
So, from these results, αCD has a possibility on the selective absorption of fatty acids relates by the decreasing of the solubilities of fatty acids in the small intestinal fluid.
⇒ In the present study, one of the mechanisms of selective decreasing effect on serum saturated fatty acids by αCD supplementation was clarified.
