  • Storage stable tomato - based sauce
    Patent number: 4840806
    Abstract: The present invention relates to a tomato-based sauce which is stable during frozen storage. By reducing the initial pH of the sauce to 4.2 or less and buffering the sauce and freezing, oxidative failure of the sauce can be substantially reduced. The prevention of oxidative failure reduces both color change and flavor change of the sauce with time.
