In April 2004, Smucker introduced "Crisco Zero Grams Trans Fat Per Serving All-Vegetable Shortening," which contained fully hydrogenated palm oil blended with liquid vegetable oils to yield a shortening much like the original Crisco. From January 24, 2007, all Crisco shortening products were reformulated to contain less than one gram of trans fat per serving; the separately marketed trans-fat free version introduced in 2004 was consequently discontinued. As of 2010[update], Crisco consists of a blend of soybean oil, fully hydrogenated cottonseed oil, and partially hydrogenated soybean and cottonseed oils. According to the product information label, one 12 g serving of Crisco contains 3 g of saturated fat, 0 g of trans fat, 6 g of polyunsaturated fat, and 2.5 g of monounsaturated fat. It is claimed that this reformulated Crisco has the same cooking properties and flavor as the original version of the product.
According to the FDA, "Food manufacturers are allowed to list amounts of trans fat with less than 0.5 gram (1/2 g) per serving as 0 (zero) on the Nutrition Facts panel."
The process of hydrogenation adds hydrogen atoms to unsaturated fats, eliminating double bonds and making them into partially or completely saturated fats. However, partial hydrogenation, if it is chemical rather than enzymatic, converts a part of cis-isomers into trans-unsaturated fats instead of hydrogenating them completely. Trans fats also occur naturally in a limited number of cases: Vaccenyl and conjugated linoleyl (CLA) containing trans fats occur naturally in trace amounts in meat and dairy products from ruminants, although the latter also constitutes a cis fat.
According this this, I would say that the world hydrogenated and trans fats are NOT the same.
