Foaming

Post by badflash »

I get a load of bakery waste from the grocery each week. They are loaded with sugar, so I figured I'd give it a shot. It ferments like crazy, but foams like nobody's business. I think it is the icing. I tried Fermcap S but it doesn't touch it. NOVOZYMES CONVERTASE AG300L seems to do a good job converting the cakes and cookies. Anyone got a solution to the foaming?

Give it room.
Sometimes adding fat or oil reduces the foaming, but I guess in bakery waste there is fat enough.
Maybe some acids might help. Or tannin?

Don't think your pigs will care if it foams....

Most cereal grains won't foam too bad in the fermenter even with glucoamylase enzymes added. Perhaps you're trying to make "a silk purse out of a sow's ear". "Free" food scraps are not always the best fermentables.

The sugar is no good for the pigs. I need to reduce it before I give it to them. I will try using a bucket instead of a fermenter.

Boil the load of waste in water and then stick it in the freezer...the sugar with be dissolved and the fat from the icing will form a hard crust on top that can be removed with ease, then ferment as normal.

If you have an ice chest large enough for a 5 gal bucket, you could fill it with 10lb of regular ice or 1/2lb dry ice, if you can get if near you...my moto is "never let free sti# go to waste"

Between buying a freezer and dry ice, the free stuff isn't so cheap...
