**2. Chemical composition of citrus fruits**

Valuable natural chemicals in citrus fruits are an excellent source of different nutrients like carbohydrates, fiber, mineral elements, and vitamins required for the human body, including vitamins C, vitamins B, potassium, phosphorous, and other elements (**Table 1**). Citrus fruits contain an impressive list of other essential nutrients both glycaemic and non-glycaemic carbohydrates (sugar and fiber).

Vitamins A and E, B vitamins (thiamine, riboflavin, and niacin), minerals, and antioxidants such as flavonoids, vitamin C, phenolic compounds, and carotenoids are many nutrients present in citrus fruits. They also contain dietary fiber, which has a positive stimulatory effect on the immune system, cardiovascular, and digestive systems [17].
