ABSTRACT
Citrus molasses was produced in Florida on a commercial scale during the canning season of 1941–1942 with a production of 2500 tons. During 1942–1943 this was increased to about 4700 tons. Approximately one-half of domestic blackstrap molasses was unavailable for feeding purposes due to its retention for manufacture of war materials. Hence citrus molasses filled a need in the manufacture of mixed feeds. The supply of citrus molasses has been insufficient to meet the demand of the mixed feed industry.
RECOVERY OF CITRUS MOLASSES
From a survey made by the Department of Agricultural Economics of the Florida station it was determined that 67.5 per cent of bulk citrus fruits remains as peel, rag, and seed, from the canning of hearts, juice, and citrus concentrate. This residue or fresh pulp contains about 85 per cent of moisture mostly as bound water, or water of constitution.
Addition of calcium salts to the fresh pulp liberates the bound water.
