Orange (fruit) orange juice between the São Paulo and mid-south Florida areas makes up roughly 85% of the world market. Brazil exports 99% of its production, while 90% of Florida's production is consumed in the United States. Orange juice is traded internationally in the form of frozen, concentrated orange juice to reduce the volume used so that storage and transportation costs are lower. Oranges, whose flavor may vary from sweet to sour, are commonly peeled and eaten fresh or squeezed for juice. The thick bitter rind is usually discarded, but can be processed into animal feed by desiccation, using pressure and heat.
Orange juice the cloud through centrifugation. The previously mentioned cloud makes up a large part of the suspension. If the suspension in orange juice is not stable, the cloud particles can flocculate which causes the suspension to physically decompose. The cloud can break apart and the citrus juice will clarify if the suspension becomes unstable. The activity of pectin methyl esterase increased the interaction between pectin and cloud proteins, which led to protein-pectin flocculation. The insoluble material of the cloud clumps in conditions above 70 °C and at a pH of 3-4 at which proteins coagulate and flocculate. Cloud flocculation is enhanced
