Abstract
Abstract Combinations of sodium chloride or potassium chloride with certain other salts provide a greater degree of water binding in meat products than they would be expected to have based on Raoult's Law. In addition, these salt combinations provide highly palatable products such as chicken, ham and shrimp when rehydrated prior to consumption. Preferred salt combinations contain sodium chloride and alkali metal citrates in a weight ratio of from 3:2 to 2:3 at a level of from 6 to 13% based on the total weight of the product which contains from above 30 to 45% water. The preferred process includes the steps of infusing the meats with an aqueous solution of the salt combinations and drying the infused meats to the desired moisture under conditions which avoid surface hardening.
