Fermentation and Color Change

[murray]

Thanks for the reply. Ive got them in the fridge and they smell good, not off or anything so ill let them run their course. To test the ph I was going to use a ph probe, is there any harm in cutting one of the zip ties off to temporarily gain access?

Some of the casings are loose as the sausages all lost between 19.4% and 21.9% in the first 72 hours (32mm casing) Does that seem like too much? Half the weight loss in the first 3 days or is that normal? The 50mm casings lost about 12.7%.
