Food Engineering, Membrane Separation Engineering, Chemical Reaction Engineering
We are taking an engineering approach to the study of separation technology, responsive technology, and measurement technology with the objective of contributing to the maintenance and promotion of health through food, securing the safety and reliability of food, and creating a sustainable society based on the effective use of food-related resources.
Separation technology is involved with the elucidation of the separation characteristics and the fouling mechanism when applied to liquid food products. The specific object is membrane separation technology for reverse osmosis, nano-filtration, and ultrafiltration, which is now attracting attention as an energy-saving, mild food product separation technology. In addition, we are attempting to create a new and efficient membrane separation system based on these results.
In the field of responsive technology, we are developing a new device capable of producing biodiesel fuel using no catalysts by the continuous injection of methanol vapor under normal pressure into oils. We are conducting basic research into the methyl esterification of oils. We are also conducting research into the measurement and evaluation of the states during different chemical reactions using extremely weak light. The results will be incorporated as the basis for the development of new measurement technology that will contribute to securing the reliability of food.
- Membrane separation technology
We have developed a new technology for the refinement of antioxidative dipeptides and anserine-carnosine at optional purity using the membrane separation technology for chicken extract (ultrafiltration and nano-filtration), and ion-exchange chromatography. There is a diversity to the active oxygen generated in organisms, and each anti-oxidant agent acts only on a specific active oxygen species. The peptide anserine-carnosine has a strong anti-oxidative effect on the CIO type, while polyphenols derived from plants, carotenoids and caffeic acid analogs have a strong anti-oxidative effect on OH type, and vitamin C has a strong anti-oxidative effect on ONOO type. This demonstrates that the appropriate distribution of food materials containing these substances will enable improvements in the preparation of anti-oxidative food products.
- Biodiesel fuel production
The only production method of commercialized biodiesel fuel is the conversion into fatty acid methyl ester (FAME) by the alcoholysis of plant oil using alkali catalysts. The effective use of the byproduct glycerin, however, requires a purification process that removes the alkali catalysts. This is an obstacle to cost reduction.
We are conducting basic research into the methyl esterification of oils and the development of a new device that can produce FAME without the use of a catalyst (the superheated methanol vapor method). The refinement of the byproduct glycerin and the cleaning of the reactive products are unnecessary, so reduced production costs are anticipated.
- The evaluation of food products using weak light measurement
Weak light is emitted from food materials in conjunction with chemical reactions. Detecting this weak light enables the measurement of the quality of the sample materials. Our objective is to easily detect the degree of degradation and anti-oxidation, the primary indicators of food material quality, without the requirement of a complex chemical analysis.
In addition, we are also conducting research into the rapid discrimination of the irradiation history of food materials by the application of light measurement.
