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 by heating the juice for 1 minute at 90 °C. Interactions of pectin The solution behavior of pectin is strongly influenced by a number of factors including hydrogen bonding, ionic character, and hydrophobic character. Hydrogen bonding is favored when pH is less than pKa while the ionic character is favored when pH is greater than pKa. Ionic character relies on free carboxyl content, the presence of cations, and is favored at a high water activity. Charge-charge repulsions along with the presence of neutral side chains are essential in inhibiting intermolecular association among pectin molecules. The methyl ester content in orange
