Review: Preserve bread - I just received this and used it in the loaf of bread that I made yesterday so it's a little early for me to really give it five stars but I did it appears in what I've been using the last few days it does work. That was good information to know on how to preserve your homemade bread.
Review: You get a lot of it, and most people only need a little of it. - I've been trying to bake my own bread lately. A full-size pullman loaf lasts me about a week. Naturally, the quality starts to suffer toward the end of the loaf. As the temperatures get warmer, I decided to food-science my way to better bread. CalPro effectively inhibits the growth of bread mold and ropey bacteria. And you really don't use much of it. In commercial pre-sliced bread the limit is 0.1% of the total weight. That means 2.2 grams in a 2.2kg loaf of bread. A home kitchen probably doesn't have the spore load of a commercial bakery, i'm not pre-slicing, and it doesn't have to stay around near as long as commercial bread. At a level of 0.5g in 2.2kg of dough i absolutely cannot taste it, but the texture of the bread does seem to hold up a little better toward the end of the loaf. A heel left in a bag in the back of the cupboard didn't mold for weeks. I could go down to 0.3%. And yet I have a pound of it. Regardless of the best-by date, it will probably still be CalPro in a decade if it's kept dry and out of sunlight.

## Questions & Answers

**Q: How do I know what I am getting? I need calcium propionate but this says or sodium?**
A: I had the same issue. My research said Calcium propionate is better for bread and sodium for cakes. The research said that sodium propionate interferes with raising. I needed it for bread. I assume I got sodium. My bread does not rise as well as before but 1 teaspoon in my bread does stop the mold.

**Q: Will this keep bread soft as well?  Or just keep mold away?**
A: It made no difference in my GF bread except cut down on the mold. Randy

**Q: what is the legal limit I can use of this in food?**
A: Legally there is no limit but good practice within the baking industry would suggest .5% or less by weight.  For example no more than 5 gm per kilogram of flour.

**Q: How much do i put in for two loaves bread?**
A: I read that 0.1% of the weight of the flour should be used. I weighed one cup of flour to be about 125 grams. So I decided on 125 milligrams. If you use 3 cups of flour for a loaf, 0.375 grams of calcium propionate would suffice. One eighth of a teaspoon of it weighed about 0.37 grams. So for two loaves you could use 1/4 teaspoon. I decided to use less though. So I use 1/8 teaspoon for one or two loaves. It seems to work for me.

### ⭐⭐⭐⭐ A very little bit goes a long way.
*by S***1 on November 11, 2024*

I use a tiny amount of this (1.5% by weight of the flour used in my baking product) that successfully deters the growth of mold past the date it is being consumed (about 10 days maximum). Works like a charm for homemade bread, which without this, starts to mold in 5-6 days. Now now thrown away moldy bread, it is all eaten before there is any hint of mold. The key with using this food-safe is to use as little as possible. I first tried using 1%, and although mold growth was noticeably retarded, it started to appear after 7 days, so I upped the next batch to 1.5% by weight of powder. That allows the bread to remain mold free for at least 10 days (always consumed by then, have not gone longer). The 1lb bag I bought should last for years and years if kept dry. Very cost effective stuff.
