Attempts were made to manufacture evaporated milks containing up to 40 per cent. of total solids. Heat coagulation was prevented either by adding 8 to 10 per cent., on a solids basis, of dried milk which had had 60 per cent. of its calcium removed by treatment of the original milk with Ambezlite IR-100, or by adding 70 to 85 oz. of disodium phosphate per 1, 000 Ib. of evaporated milk containing 40 per cent. of solids. However, noticeable mineral deposits were found a few days after sterilization in all products containing 32 per cent. or more of solids. The pH decreased with increases in the total solids whereas the percentage destruction of optically active lactose appeared to be unrelated to the solids content.
