We use pasteurized egg whites (powder) as an ingredient in our product. After egg white powder is mixed with water and invert sugar (liquid sugar), we have to use it with in 4 hours. If it passes that threshold, we discard it. Recently we purchased a big egg slurry machine that can mix for us in big volume. In this case, after the mixing it will sit longer than 4 hours.
So my question is, what is the shelf life of powdered egg whites after it is mixed with water and liquid sugar? Can anyone provide me with a source or information on this. Is it safe to keep it longer than 4 hours, like 10 or 24, hours?
Your response is much appreciated!
