  • Mixtures with stabilising properties
    Patent number: 11219230
    Abstract: The present invention primarily relates to novel mixtures with stabilizing properties, particularly for avoiding, reducing or delaying the formation of sensorially undesired flavours and/or tastes in oxidative degradation processes or autoxidative processes or reducing, avoiding or delaying oxidative processes in one or more oxidation-sensitive compounds, particularly autoxidative processes, their use in specific preparations as well as novel preparations and methods of producing such preparations. Additionally, herein described are methods for decreasing, avoiding or delaying the formation of sensorially undesired flavours and/or tastes in oxidative degradation processes or autoxidative processes or for decreasing, avoiding or delaying oxidative processes in one or more oxidation-sensitive compounds, particularly autoxidative processes.
