Hi folks,
I don't post here often, but I come now to seek for your help.
I've been growing Tempeh for almost a year now and I have overcome different problems through experience, but I can't seem to find the cause of this problem:
Sometimes the mold just grows on the outer rim of the cake, and leaves the insides uncolonized - sometimes it get contams in there, which I've learned to avoid and aren't present on this small batch.
The only possible explanation I can think of is that the inside gets more of its own heat and hinders growth, whereas the outer parts stay cooler and have more favorable conditions for full growth.
Could this be the reason? If yes, how can I alleviate this problem?
Is it maybe because the strain's got old? and weak?
This picture is taken after 60 hours of inoculation, but it was already like this after 40 hours.
Please, share your thoughts and experience - what can I do for the mold to colonize the full cake as perfect as it does on the outer parts.
Any insights are deeply appreciated!
Many thanks in advance
