Claim 6:
7. The method as claimed in claim 1, wherein by using the salt-repellent technique, salt-free ice crystals are produced without the need for washing the crystals due to the use of a salt-repellent additive selected from the group consisting of surface-active agents, including sodium lauryl sulphate, sodium lauryl ether sulphate, and glycols such as ethylene glycol, propylene glycol, polyethylene glycol, glycerine and alcohols such as isopropyl alcohol, methyl alcohol, ethyl alcohol, normal butyl alcohol, isobutyl alcohol, benzyl alcohol, and esters such as ethyl acetate, methyl acetate, butyl acetate, amyl acetate, benzyl acetate, ethyl benzoate, butyl butyrate, acetoacetate, and ketones such as dihydroxyacetone, methyl ethyl ketone, propanone, acetophenone, benzyl phenome, and butanone and chemical reagents such as fructose, silver nitrate, sucrose, cyclohexylamine, and propylamine.
