HELP - how do I prevent the fat from rendering out
That is correct. I should have stated that the instantized (agglomerated) milk has a higher level of solubility that the non-instant type. Instant milk contains more undenatured whey proteins than non-instant, which has a fewer amount and results in better binding qualities in sausage.Bob K wrote:They both are water soluble. The powder just takes longer, so may retain more water during processing time. It is also less expensive.

So if you read the article, you will see that the two types differ in the way they are prepared. Non-fat instant milk solids are prepared using high heat. And the reason why it has better binding properties is because preheated whey protein can form cold-set gels, that improve water binding and texture. (Rodrigo Tarté, Ingredients in Meat Products
