Latest Patents

One of Toyoda's latest patents is a process for the manufacture of fermented milk. This innovation involves a method that allows for a controlled acidity increase during the storage and transportation of fermented milk. By inoculating raw milk with a nisin-producing lactic acid bacterium, specifically Lactococcus lactis subsp. lactis, along with other lactic acid bacteria, Toyoda's process ensures that the nisin produced suppresses the growth of bacteria that contribute to acid formation. This control over acidity helps maintain the quality of the product during its shelf life.

Another significant patent involves lactic acid bacteria that produce an antibacterial substance. This patent discloses the use of Streptococcus salivarius subsp. thermophilus and its variants, which are capable of producing a peptide or protein that acts as an antibacterial agent. The use of these bacteria as starters in the fermentation process inhibits the growth of other lactic-acid-forming bacteria, thereby preventing taste and flavor variations in the final product.
