Abstract
A novel salt composition and a corresponding method of manufacture are described herein. The salt composition is formed from a plurality of salt crystals with a surface area of at least 0.19-0.23 m2/g and a Hall density of less than 0.8 g/cm3. In some embodiments, at least a portion of the salt composition has a hopper cube morphology.

A salt composition comprising a plurality of salt crystals with an edge length between 10 μm and 150 μm, a BET surface area of at least 0.19-0.23 m2/g, and a Hall density of less than 0.8 g/cm3, wherein the plurality of salt crystals comprises a first portion having a mature hopper cube morphology, a second portion having a simple hopper cube morphology, a third portion having a hollow cube morphology, and a fourth portion having a solid cube morphology.
A method for forming a salt composition, the method comprising:
- providing an antisolvent solution;
- adding a salt solution to the antisolvent solution to form a supersaturated solution, wherein the salt solution has a concentration greater than 15 wt % solute, and wherein the mass ratio of the salt solution to antisolvent solution is in the range of 1:20 to 1:1.25;
- and
- crystallizing the supersaturated solution to form the salt composition with a plurality of salt crystals with an edge length between 10 μm and 150 μmm, a BET surface area of at least 0.19-0.23 m2/g, and a Hall density of less than 0.8 g/cm3, wherein the plurality of salt crystals comprises a first portion having a mature hopper cube morphology, a second portion having a simple hopper cube morphology, a third portion having a hollow cube morphology, and a fourth portion having a solid cube morphology.
A food product comprising:
- an outer surface;
- and
- a salt composition applied to the outer surface of the food product, wherein the salt composition comprises a plurality of salt crystals with an edge length between 10 μm and 150 μmm, a BET surface area of at least 0.19-0.23 m2/g and a Hall density of less than 0.8 g/cm3, wherein the plurality of sodium chloride crystals comprises at least one of a first portion having a mature hopper cube morphology, a second portion having a simple hopper cube morphology, a third portion having a hollow cube morphology, and a fourth portion having a solid cube morphology.
