MSG, or monosodium glutamate, is a common and widespread additive in food used mainly for flavor enhancement, but also for preservation. MSG has been used for well over a century as a food additive, but in the last couple of decades anecdotal claims of illness have been linked to MSG consumption.SG is the salt form of glutamic acid, which is a naturally occurring amino acid. Seaweeds and many other plants and vegetables contain glutamic acid.
From Wikipedia, the free encyclopedia. Auto-defrost, automatic defrost or self-defrosting is a technique which regularly defrosts the evaporator in a refrigerator or freezer. Appliances using this technique are often called frost free, frostless or no-frost.
Newer refrigerators may include: 1  Automatic defrosting. 2  A power failure warning that alerts the user by flashing a temperature display. 3  Chilled water and ice from a dispenser in the door. 4  Cabinet rollers that lets the refrigerator roll out for easier cleaning. 5  Adjustable shelves and trays.
