What is vegetable broth's problem?

[Kali]

6. broths are by nature nutrient rich liquid.

once open they are subject to spoilage by bacteria. they are almost a perfect medium for growing bad stuff. freeze what you can't use up and it will be fine. I find chicken broth to be fine for at least 10 days if promptly closed and refrigerated.

if you have the freezer space try making your own. the flavor is much better and then you know what is in it. save up veg peels and scraps in the freezer again. I also do this with meat scraps and bones. no need to shop separately just for broth ingredients.
