What should Lactobacillus serum smell like?

DankTankerous · Jun 15, 2021

A friend of mine gave me some LaB that smells like bad breath (halitosis) and I made some that smells like rich cheese. Last time I made LaB serum it smelled like cheese and carried the scent and a 4.0 pH for two years even without any sugar mixed it. The new batch has organic brown raw sugar and has that smell.

What “should” it smell like?

11. LAB culture should have a sweet odor; if the odor becomes unpleasant (rotten) after it has been stored, discard it and make a new batch

Ok cool, I gave some of that bad LaB (unbeknownst to me) to my cats and their crap smelled like the bad breath LaB (I didn’t pick up the shit and smell it, I just have an incredible sense of smell). I knew something wasn’t right because if anything it should make it smell less not worse. Thank you for your help

I use molasses in mine and it always smells sweet. If it smells bad it is bad

Was there by chance any dairy in this? Milk, cream, and butter contain lipase enzymes which produce the smell of aged type cheese like parmesan from even the smallest amount of fat present. Ask anyone whose tried to make a bar of homemade soap from butter fat. It's like rubbing yourself with a chuck of vile vomit. Lola

Excellent with the 4.0 pH. It's what LABs do. They eat sugar and poop lactic acid making it very difficult for other microorganisms to compete and survive because of the low pH. That should be shelf stable for a very long time under reasonable environmental conditions.

Oh yes, whole organic milk.

Mine tends to have a cheesey smell to it, after I add the molasses to make it shelf stable it has a sweeter smell.

I wish I could get unpasteurized organic whole milk for my other hobby - cheese making. Sadly that is illegal here, so need to compensate by adding extra calcium, etc. But yeah, that's where your smell comes from. It should be good as an additive to a very nice salad dressing, or if you must add it to your plants. Lol

Where are you that unpasteurized milk is illegal? In Australia is it illegal to sell it but not illegal to use it to make cheese. Just one of our many ridiculous laws.

We have a Jersey house cow and am looking at getting some Nigerian Dwarf Goats. Both make excellent milk and cheese.

I'm in Canada. I'm not sure, but oddly it seems we can import European cheeses made from unpasteurized milk, but we can't make it here. I suspect the law comes from simple cost-benefit analysis. The testing burden would be increased for products made from unpasteurized milk, so the government agency would just prefer to avoid it all together due to increased costs, while directing its quality assurance towards imports.

If you know a small private diary here, then you can get unpasteurized milk. It's kinda like growing 5 or 6 plants instead of your 4 legal plants. You won't get jail time, but a slap on the wrist (fine) might hurt some folks. I know some small distributors have been busted for it here in Ontario though over the past years.
