Sweet Orange, or Citrus sinensis (also called Citrus aurantium dulces), is a fruiting tree that belongs to the Rutaceae family of citrus plants. Originally, the Sweet Orange tree was believed to be a form of the Bitter Orange tree or Citrus aurantium amara and was referred to as Citrus aurantium var sinensis. It is believed that oranges were first obtained from trees native to China but the exact origin of the Sweet Orange is unknown as it does not grow anywhere in the wild. Botanists believe that Sweet Oranges occur as a natural hybrid of the pomelo (Citrus maxima) and the mandarin (Citrus reticulata) citrus trees and originated somewhere in the southwest region of China.
Sweet Orange trees are evergreen and typically grow to be around ten to twenty-five feet in height, but can reach up to fifty feet at a mature age. They have grayish-brown bark and slender branches that grow evenly around the tree, forming the shape of a hemisphere. The leaves of the tree are oval-shaped and dark green with a glossy surface and grow to be around three to four inches. Sweet Orange trees produce small white flowers that grow individually or in small clusters and are beautifully fragrant. Sweet Orange fruits are round with a thick, almost leathery rind that changes from green to orange in color as the fruit ripens. In warmer climates, the rind can retain patches of green color or even stay entirely green. The rind of the fruit is dotted with glands that contain the essential oil. On the interior side of the orange's rind is a layer of spongy white tissue commonly referred to as the “pith”. The flesh of Sweet Orange fruits forms in a dozen wedge-shaped segments that are each covered in a thin translucent membrane. Each section contains two to four seeds, and juice-filled pulp, which can range from yellow to red.
Sweet Orange Essential Oil has been used for thousands of years in folk remedies across China, India, the Middle East, and the Mediterranean to help naturally boost the immune system and relieve symptoms associated with colds, flu, fatigue, depression, and many other ailments. In China, oranges are a significant part of traditional medicine, even today, as they are believed to symbolize good fortune. The Sweet Orange was mentioned in Chinese literature as early as 314 B.C. Sweet Oranges are believed to have been introduced to the Iberian Peninsula during the tenth century. This idea is supported by the existence of complex irrigation techniques that are specifically adapted to support orange orchards. Sweet Oranges did not spread into the Mediterranean until the beginning of the fifteenth century when Portuguese and Italian merchants brought the trees into the area. Soon after, the Sweet Orange was recognized as an edible fruit but was considered a luxury item afforded only to the wealthy. By the middle of the seventeenth century, oranges were well known throughout Europe, with many European aristocrats having private orangeries at their estates. Louis XIV, king of France built a particularly grand Orangerie at the Palace of Versaille as he had a great love of orange trees. This allowed the year-round cultivation of oranges for food for the court.
It was Spanish travelers that eventually brought the Sweet Orange to the Americas. In 1493, on his second voyage, Christopher Columbus brought orange seeds and may have planted them in Hispaniola. During the Age of Discovery, sailors from many different countries would plant citrus trees, including oranges in places along their trade routes. This was done to help sailors consume more citrus to prevent scurvy, as oranges are high in vitamin C and do not spoil easily. Oranges were spread to South America and Mexico during subsequent expeditions in the sixteenth century and eventually made their way into Florida in 1565 when Pedro Menéndez de Avilés founded St Augustine. Orange trees were spread across North America over the next two centuries by missionaries and explorers. Orange trees finally made it to the Hawaiian islands in 1792. A botanist named Archibald Menzies collected orange seeds in South Africa and raised the seedlings onboard a ship during his travels, later giving them to several Hawaiian chiefs. The Sweet Orange was grown widely throughout Hawaii until the arrival of Mediterranean fruit flies stopped its cultivation in the early twentieth century.
Unlike many other fruits, the Sweet Orange does not continue to ripen once harvested. This means that the fruit must be harvested at the right time to ensure maximum ripeness and essential oil yield. Oranges are still harvested by hand in some cases but many oranges cultivated for essential oil production are mechanically harvested with the use of limb shaking machinery or air jets. Sweet Orange, like many other citrus essential oils, is extracted from the rinds of the fruit through cold pressing. To process oranges for extraction, the rinds are removed from the fruit and can be punctured, ground, or chopped before being pressed. Cold pressing protects antioxidants and their beneficial aspects of the oil from being destroyed by heat. The resulting essential oil is thin, can vary from yellow to deep orange, and has a sweet, fresh citrus aroma.
Sweet Orange oil is a byproduct of the juice manufacturing industry. There are two types of extractors. One method of extraction scrapes the outer layer of the orange peel, water is added and the essential oil is separated in a centrifuge. The fruit then goes to a juice press. Another method of extraction uses sliced oranges. The half orange slices are then pressed. The result is a mixture of juice and essential oil which is then separated in a centrifuge
