Title: **Hirokazu Maeda: A Pioneer in Emulsifying Agents**
Introduction
Hirokazu Maeda, based in Izumisano, Japan, is a distinguished inventor known for his contributions to the field of emulsifying agents. With a remarkable portfolio of 30 patents, Maeda has focused on developing innovative solutions that enhance the stability and effectiveness of emulsions, particularly those derived from natural polysaccharides.
Latest Patents
Among Hirokazu Maeda's latest patents are two significant inventions:
1. **Polysaccharides and protein conjugate, and emulsifiers and emulsions containing it**
This invention addresses the need for emulsifying agents of natural polymer type, particularly polysaccharide types. While these emulsifying agents offer excellent emulsion stability, they often fall short in emulsifying power and tend to produce emulsions with larger particle diameters. Maeda's innovation introduces a polymer-type emulsifying agent combining high emulsifying power with the ability to achieve smaller emulsified particle diameters. Specifically, it includes a composite of a polysaccharide with a protein containing at least 10% proline and a molecular weight of 50,000-80,000 Da.
2. **Carboxylic acid and amino acid or amino condensate reactants and manufacturing method therefor**
This patent outlines a novel manufacturing method for creating carboxylic acid and amino acid reactants. The process is notably straightforward and avoids the use of toxic substances, providing a safe solution for producing these reactants. The method involves heating a mixture of carboxylic acids and amino acids or their condensates in an aqueous system at temperatures ranging between 100°C and 180°C, without dissipating the water.
