My cousin and I made up our fourth batch of snack sticks and this is the second batch that we dehydrated (at 150 F). He mentioned that when squeezed they oozed something yellow and cheese-like and I suspect it's fat (there was no cheese added to the mix).
I'm thinking we just way overdid the fat content. The recipe suggestions are to use 7# of venison to #3 of pork trim. Assuming an up to 50% fat content on trim the max of the recipe would normally be around 15% fat. When we did this last batch we did all 9 lbs pork shoulder (assuming 20% fat) and 1 lb fat back making 28% fat if my math is correct. For normal sausages this ratio normally would be fine for me but I think the heat+dehydration did me in. Definite greasiness in the throat after eating.
Edit: With additional introspection I also realized that we dehydrated at least 30% weight loss which would have jacked the fat content into the stratosphere. At least they're still tasty!
Apologies for the bad picture, I was at a stop light....
