Another object of the invention is to provide a process and apparatus of the above character in which the steam can be recirculated and reused without being condensed into liquid water. This process can be carried out at relatively low pressures and is preferably carried out at or near atmospheric pressure or in vacuo. When operating at or near atmospheric pressure, excellent hydrolyzation is obtained even though the amount of water in the gaseous phase, i.e., steam is not much greater than that required stoiehiometrically (3 mols of water for each mol of fat). A common type of hydrolysis occurs when a salt of a weak acid or weak base (or both) is dissolved in water. These saponification reactions can be one step or two step process. (i) CH3CH2COOH In a preferred embodiment, this gaseous phase can be in the form of superheated steam. It affects millions of people worldwide, and the number of diabetes patients is increasing at an alarming rate. If the unsaturated fat contains multiple double bonds, then it is known as polyunsaturated fat. Production of omega 3, 6, and 9 fatty acids from hydrolysis of Effects of acute and chronic exercise on fat metabolism. The steam thus preheated is introduced as superheated steam into the reactor 11. This chemical process continues during frozen storage, though more slowly at lower temperature. In biological hydrolysis, the water molecules react with large biomolecules and break them into smaller components. 3. A (i), (ii) and (iii) only Fat oxidation rates increase from low to moderate intensities and then decrease when the intensity becomes high. [q2Y;({1X7^S- 1m0 7X2@ nG3adN%4;ob;5;FTpV9&Uo@Ab6FXP>D. Suitable feeding means 16, such as a T, is provided on the inlet end of the reactor l0.
