  • Publication number: 20160058060
    Abstract: The invention provides a multi-component homogenous co-crystallized low sodium salt product for food and pharmaceutical use. The salt product of the invention is essentially segregation-free, has low hygroscopicity and is free-flowing. It has good microbial depression properties and good taste. It supplies the functionality of salt (NaCl) in processed foods and it also maintains the microbial safety, nutritional value and taste. The salt product of the invention includes an alkaline and alkaline earth metal chloride component and an ammonium chloride component. An alkaline metal is potassium (K), and optionally also sodium (Na). An alkaline earth metal is Magnesium (Mg) or Magnesium (Mg) and Calcium (Ca) having the sum of the molar ratios 1. The invention provides also a process to produce the salt products of the invention.
