Development of a bidirectional mass transfer device with food component ratio modulation function

Abstract

There are a wide variety of food ingredients, including molecules that "enhance" and "inhibit the function of certain bioactive substances" - unknown molecules! Since its physiological activity is exerted in a complex system in which - coexists, the component ratio is the key. In order to optimize the expression of bioactivity, it is necessary to change the component ratio freely, however, there is no such thing. Thus we have developed a bidirectional mass transfer device. In this device, when a solution with different component ratios is sent to the upper and lower flow paths in the filter, a low molecular weight substance moves in both directions in the upper and lower flow paths due to the balance between the diffusion rate constant and the flow velocity. By changing the delivery time, the component composition on both sides can be varied step by step. In this article, we will report on the performance of the device.

We have shown that this device has the ability to change the component ratio of the solution flowing to one side reproducibly by dialyzing the circulating water on the other side.
