Fruit and vegetable juices are very good sources of the essential
nutrients. Orange and grapefruit contains nutrients, micronutrients,
vitamins and a mineral profile that is low or free of sodium while being
high in potassium.
Most citrus cultivars are free of lipids, contain high levels of
vitamins C and contain folate acid, thiamin, and to a lesser extent
vitamin B6, niacin and riboflavin.
Vitamin C is relatively stable in citrus product during processing and
storage. In addition to vitamin C or ascorbic acid, citrus juices also
contain vitamin B complex and provitamin A.
Orange is rich in vitamin C and potassium and low in sodium. Grapefruit
juice contains a lower concentration of folate, thiamin and niacin than
orange juice.
The juice of citrus fruit contains about 0.4% ash. The ash content of
orange juice was generally the highest in immature fruit and gradually
decreased as fruit maturity progressed.
