Products were manufactured from cull oranges rejected from processing plant grading lines. Cull fruit juice yields were 20% less than from sound fruit. Frozen concentrate had a detectable stale fruit off‐flavor. Total reducing sugars were 10% higher and vitamin C was 8% lower in the juice from the cull fruit, while color, cloud and viscosity were about the same as in juice from sound fruit. The aldehyde content of cold pressed oil from cull oranges was too low to meet U.S.P. specifications. Dried pulp cattle feed and molasses yields from culls were greater than from sound fruit. Crude protein content of the cull dried pulp was 6.6% and total sugars (reducing and sucrose) of cull fruit molasses was 58%; while the cull orange molasses had a viscosity of over 20,000 c.p.
