Khalal- Which is full-size and crunchy.

Rutab- Which is ripe and soft in variety.

Tamar- Which is ripe and sun-dried.

It is seen that during the ripening process the fruit starts losing its moisture content and its sugars are converted to glucose and fructose.

The moisture content of fresh date is between 37.6 and 50.4 g/100g. The moisture content of dried dates is between 7.2 and 9.5/100gm.

Nutritive Value of Dates

Dates contain 70% of carbohydrate. It includes sugars, sucrose, glucose, and fructose. Sugars found in dates are easily digested. It helps in the release of energy. Glucose and fructose which are present in date flesh are readily absorbed during the process of digestion. It helps in the rapid elevation of blood sugar levels.

  • It provides 3150 calories of energy per kilogram.
  • It contains 15 salts and minerals.
  • It has 5.6% of proteins.

It contains vitamin A, A1, B, B1, B2, B3, B5, B6, and C as well as a variety of amino acids. These vitamins and minerals help the body produce hemoglobin, which is a protein in red blood cells that binds to oxygen and carries oxygen from the lungs to tissues.

It contains potassium which is an essential mineral that helps in proper muscle contractions. Potassium is also necessary for a healthy nervous system. Soluble fiber has been shown to help control diabetes by decreasing high blood sugar as well as lowering high cholesterol, specifically low-density lipoprotein (LDL) cholesterol. Insoluble fiber increases the body’s ability and the rate at which food is processed through the digestive system. The flesh of dates contains 0.2 /0.5% oil, whereas the seed contains 7.7 /9.7% oil.

It is a good source of fiber. The main fibers are cellulose, hemicelluloses, pectin, lignin, and insoluble proteins. Insoluble fiber is the major component of dietary fiber in dates. Dates are a good source of dietary fiber. It has both soluble and insoluble fibers.

  • It contains minerals mainly calcium, iron, fluorine, and selenium.
  • It has antioxidant properties.
  • It protects against cancer.

The protein content of date fruit is between 1-3%. It is seen that protein and lipid contents increase after drying. This occurs as a result of the loss of moisture.  The average protein content of fresh and dried dates is 1.50 and 2.14 g/100 g. Lipids are found in the skin of date.

The average lipid content is about 0.14 g/100 g in fresh and 0.38 g/100 g in dried dates.  The date seeds are also a rich source of dietary fiber (73.1 g/100 g), phenolics (3942 mg/100 g), and antioxidants (80,400 μmol/100 g) and therefore could potentially be considered as an inexpensive source of dietary fiber and natural antioxidants.

The date flesh and seed both contain a wide range of saturated and unsaturated fatty acids. The saturated fatty acids include capric, lauric, myristic, palmitic, stearic, margaric, arachidic, heneicosanoic, behenic, and tricosanoic acids. Unsaturated fatty acids include palmitoleic, oleic, linoleic, and linolenic acids.

Dates contain high levels of selenium, copper, potassium, and magnesium, moderate concentrations of manganese, iron, phosphorus, and calcium, and small quantities of boron. It is the ideal food for patients with high blood pressure as it contains a high amount of potassium and low sodium content.

It also contains boron which is useful in the treatment of cancer of the brain.  The date can be used as a practical supplement for iron deficiency without any side effects such as nausea, headache, and anorexia that may occur with iron tablet supplements.  At least six vitamins (thiamine, riboflavin, niacin, ascorbic acid, pyridoxine, and vitamin A) have been reported to be present in dates in visible concentrations. Dried dates can be regarded as a moderate source of vitamin riboflavin, pyridoxine, niacin, and folic acid. Thiamine, ascorbic acid (vitamin C), and vitamin A are present in relatively low concentrations in dried dates.

Dates contain various types of phytochemicals such as carotenoids (beta-carotene, lycopene, lutein, zeaxanthin, neoxanthin, etc.), the phenolics, mainly the cinnamic acids and their derivatives (ferulic, sinapic, syringic, vanillic, gallic, caffeic, protocatechuic, coumaric acids, and their derivatives such as dactilyferic acids, etc.), flavonoid glycosides (luteolin, methyl luteolin, quercetin, and methyl quercetin) flavones, flavonols (catechin, epicatechin), flavoxanthin, anthocyanins. The concentration of these phytochemicals decreases as the maturity of fruit increases.

It is a good source of phenolics.
