Orange production in Brazil Brazilian reals. Orange production in Brazil Brazil is a major producer of oranges. The orange was introduced to Brazil by the Portuguese around 1530. According to the statistical database of the United Nations Food and Agriculture Organization, 702,200 hectares of oranges were harvested in 2013; this is down from 836,041 hectares in 2003. Brazil is also the world's largest exporter of orange juice. According to the United States Department of Agriculture, the country shipped 1.2 million metric tons of orange juice in 2012—twelve times more than the United States, the world's second-largest exporter. In 2013, it was reported that many
Orange juice at pH 3.5 and can result in clarification, which is undesirable in orange juice. The suspension is unstable when the zeta potential is less than 25 mv in magnitude. Zeta potential is a measure of the magnitude of electrostatic forces between particles, which affect repulsion, and attraction between particles. A low zeta value signifies that the repulsive forces will not be able to overcome van der waals attractions between cloud particles and thus begin to agglomerate. Agglomeration of cloud particles will prevent free flow characteristics, which is essential in the juice. A high zeta potential will inhibit particle-particle agglomeration and
