Q
Can powdered milk have a problem with mold?
Answer(s)
A
Mold requires some moisture to grow. It only needs a little, such as in bread. If the powdered milk is kept dry in a bag or can, mold will not typically grow. If you are referring to home food storage, it is best to store powdered milk in a sealed #10 can using oxygen absorbers.

- Are jars that have air bubbles in them after bottling, safe?
- I have a question regarding commercially canned tomatoes. I have read on your website that the nutritional value of vegetables may not be maintained after the expiration date. I have heard somewhere that tomatoes are an exception, and there could be a problem with the tomatoes that would not be able to be detected, and that they should just be discarded at the expiration date for safety's sake. Is this true?
- I've read that dry pack food storage products expire within x amount of years depending on the product. My parents purchased a LARGE quantity (over 100 cases of #10 cans) of assorted dry pack 28 years ago from Desert Supply Company; wheat, cornmeal, powdered milk, eggs, instant potatoes etc. I'm having a hard time coming to terms with throwing it all out. Can you please confirm that this is wasted product or is there anything salvagable.. and if so for how much longer would it be good? It has been stored in a dry/dark cool basement.
- We canned some tomato product (pizza sauce) using a combination of roma tomatoes and regular tomatoes. Some of the tomatoes had blossom rot, which I cut off. We did not do anything to increase acidity and canned them in a steam canner. Now, I'm reading things online about botulism and canning and low acidity and I'm freaked out. Should I discard my sause? If any botulism toxin exists, will boiling the sause for 10 minutes before use be sufficient to salvage it?
- This is a food storage question. I have called Iams and Purina re cat food storage. They could not tell me how long I could store their dry food product in an oxygen free envirenment. I would like to store the food in 6 gallon buckets to which an oxygen absorber has been added. I have several members in my ward who are interested in this answer. Do you have any experience with this?
- Someone told me steam canners should not be used for canning tomatos. Is this true? On your tomato canning instructions it only refers to hot water bath or pressure canning. I've always used my steam canner and love it.
