| Outline of Final Research Achievements |
In order to effectively utilize perilla proteins, an unused food resource, we measured their emulsifying activity. Perilla proteins had 2.9-times higher emulsifying activity than soy protein isolates (SPI), which are a widely used plant protein in the food industry. Perilla proteins were divided based on differences in solubility into albumin, low-molecular-weight globulin, and high-molecular-weight globulin fractions, and the emulsifying activity of each fraction was measured. As a result, the low-molecular-weight globulin fraction was found to have the strongest emulsifying activity. The main protein of the low-molecular-weight globulin fraction was a monomer of approximately 12,000 kDa, and this molecule may be composed of 2 disulfide-bonded subunits of approximately 6,000 kDa.
