I recently received almost 6 lbs of Z-Trim, and was wondering if anyone had any recipes or has used it qualites, properties, etc. Z Trim is a corn-based, zero-calorie fat substitute that can replace up to half the fat in a food, seemingly without altering its taste or texture. FiberGel Technologies, a subsidiary of Z Trim Holdings, bought the rights to develop Z Trim in 2002. Since then, the company has been finessing both the product and the manufacturing process. As a food ingredient, Z Trim is a gel formed from 96 percent water and 4 percent fiber derived from corn hulls, a by-product commonly fed to cattle or added to dog food. Wrongly identified by some as an interesterified fat, Z Trim is not any kind of oil or fat, let alone a modified one. Nor is it a gum, such as carrageenan or xanthan gum, which can affect the texture of reduced-fat foods.
