Starter Culture Bactotoferm- FR M-52 (need help)
-
Robin05 So 72-90° is recommended for fermentation for use with this. I would get it up into that range and within 24 hours you should start to see some drop but if you are down on the 67° side of that scale it is going to be sub-optimal.
-
Robin05 It usually takes mine a couple of days to get down to 5.0 I try and keep my temps around 70-72°.
-
I made a small batch of sausage and I used the recommended amount of Bactoferm F-RM-52 and 0.8% dextrose. The sausage is hanging in a controlled environment: 67 - 73 F and 85% humidity. The initial pH was 5.8. After 10 hours, the pH is still at 5.8. How long should it take for the pH to drop to 5.0 or lower?
Robin05 it can take 2-4 days to reach the lower ph. Naturally the lower the temperature the slower the fermentation, but with 52 it will produce a better product at the lower end of the temperature range. I would not go below 70f as that is really below the value of the culture.
-
My max temp is around 75 because at higher temperature I can’t maintain humidity and I need the humidity to avoid case hardning
Robin05 to avoid humidity issues simply wrap the sausage in cling film and the sausage will not dry out thus no case hardening. Once fermentation is complete remove film and process as desired.

mrobisr Cling film? Are you talking about a plastic wrap or is this something I am unaware of? Remember I’ve only made 3 batches of cured sausage. Was planning on using 2021 to work on it but then everything kept going insane! Hopefully, 2022-23 will allow me the time to learn the process better.

Jonathon yes sir plastic wrap or as a brand Saran wrap

Robin05 the recipe you have calls for cure #1? We’ve (my brother and I) always used cure #2 for all our dry cured products.
-
Ronald Dore if it’s a short cure <30 days or cooked as Robin mentioned in another post then cure #1 is the right cure.
-
Sorry I missed this conversation. The pH will dip faster in slightly higher temps and humidity. I normally try to keep my humidity at 90% and temps 75F. To achieve the 90% I just wrap each sausage in plastic wrap and put it in my warmest room in the house

mrobisr Agreed. Didn’t realize there was another post on this topic. Thought he was going for a fully dry cured product.

Understood, here’s that other conversation.

The dry sausage is in a collagen casing and then wrapped in saran wrap for the fermentation phase only, to maintain the very high humidity necessary for fermentation. The little mini one to the side is to measure the ph of meat so I don’t have to puncture the cased sausage. Once fermentation is complete the wrap is removed and the meat is put into a drying chamber. -
When doing dry sausage there are two totally different steps that make the meat safe and flavorful. Don’t confuse the fermentation process with the drying process they are completely different and have different goals.
You have to maintain 90% or higher RH for proper fermentation verses 80% RH in a drying chamber. Since fermentation lasts typically
days at a set temp it just easier and just as effective to wrap for high humidity then place the “cased” meat in and actual chamber for the months of drying.Ultimately if a person had unlimited space and money a separate fermentation chamber and drying chamber would be perfect, but for the home charcuterie maker I have found that keeping the fermentation process simplified is just as effective. If my sausage reaches the 4.9-5.2ph then I have achieved my goal of a safe product. PH keeps the meat safe, the high humidity allows for the fermentation to accomplish the lower PH, and the casings simply hold the meat together no more or no less.
Casings are not a barrier to pathogens in dried sausage products, with or without a casing the process still remains the same for a safe product.
