Peanut butter

Peanut butter is made from peanuts, or peanuts. Contrary to the name "peanut", the peanut fruit is not a nut. Botanically speaking, the peanut fruit is a bean. It grows on an annual legume grass. After pollination of the flower, its peduncle lengthens, sinks into the ground, and already underground an ovary is formed on it. Peanut fruits ripen inside a non-opening bean pod, which contains 2 to 4 fleshy seeds.

What happens

Peanut oil is obtained by cold pressing ground ground nuts.

It is unrefined and refined. The unrefined oil is dark red in color and has a rich, nutty flavor. The refined product has a straw-yellow color and a delicate taste, and, in turn, is divided into deodorized and non-deodorized.

The method of cold pressing, in which the raw material is not affected by any chemicals or temperature, produces the most useful oil, which can be used both in cooking and for medicinal purposes.

Chemical composition

This peanut product contains lipids (consisting mainly of unsaturated fats and phytosterols), vitamins, minerals, polyphenols (resveratrol), aromatic acids (p-coumaric), proteins and carbohydrates.

There are few proteins and sugars in this oily product - the so-called traces. All of them remain in the bean cake after the oil has been pressed. A small amount of the amino acid betaine (up to 1.5 mg per 100 g of oil) enters the oil from peanut proteins.

Oil contains 95-97 g fats, of which up to 83% are unsaturated. Among unsaturated fats, omega-9 and omega-6 fatty acids make up the largest amount in peanut butter - up to 45%, which is about 150% of the daily requirement of the human body for them. The most useful omega-3s are contained in it in a small amount - 0.006 g per 100 g of fat (less than 1% of the daily requirement).

Unsaturated fatty acids
Name Content per 100 g, grams
Oleic omega-9 37.6-47.2
Eruc omega-9 1.0-1.2
Linoleic omega-6 30.0-31.0
Gadoleic omega-9 1.7-1.8

A positive feature of the fat composition Peanut butter is characterized by a high content of phytosterols - 0.44 g, which is about 150% of the daily requirement of the human body for them.

Name Content in 100 g, milligrams
Beta-sitosterol 260.0-330.0
Campesterol 68.0
Stigmasterol 1.4

Peanut butter is a source of fat-soluble antioxidant vitamin E (over 120% of the daily requirement) and biotin (160%). It also contains many B vitamins, which are involved as coenzymes and catalysts in lipid, water-salt and protein metabolism, promote hematopoiesis.

Name Content in 100 g, milligrams
Vitamin B1 (thiamine) 1.28-1.48
Vitamin B2 (riboflavin) 0.22-0.27
Vitamin B4 (choline) 1.0-1.1
Vitamin B5 (pantothenic acid) 3.5
Vitamin B6 (pyridoxine) 0.69
Vitamin B9 (folic acid) 0.48
Vitamin PP (nicotinic acid) 37.8
Vitamin C (ascorbic acid) 10.6
Vitamin E (alpha tocopherol and gamma-tocopherol) 33.4-37.0
Vitamin H (biotin) 0.08

richer than the fruits of this plant themselves: a lot of macro- and microelements after pressing the oil remain in the cake. But minerals important for the life of the human body also pass into vegetable oil: manganese (up to 80% of the daily requirement), magnesium (up to 40%), copper (up to 25%), iron, zinc and selenium.

Obesity can develop when consuming peanut products, including peanut oil.

A significant predominance of omega-6 over omega-3 fatty acids when this fat is consumed in large quantities can cause a paradoxical hypercholesterolemic effect.

Peanut oil is a food that is difficult to digest. It can cause allergies: according to statistics, up to 0.6% of Americans are allergic to peanuts and peanut products. An allergy to peanut butter is manifested by a hypersensitivity reaction, which, if precautions are not taken, can result in anaphylactic shock, including to other foods.

Incorrect storage of peanuts before extracting oil from them can lead to the accumulation of plant poisons in them - aflatoxins. Aflatoxins have dangerous actions for the human body:

  • hepatotoxic (impair the functioning of the liver);
  • embryotoxic (contribute to the occurrence of mutations in the tissues of the embryo until its death);
  • teratogenic (cause fetal malformations);
  • mutagenic (increase the likelihood of oncopathologies);
  • immunosuppressant (suppresses the immune system).

Peanut butter is not recommended for pregnant or breastfeeding women. It is also undesirable to use it for people suffering from:

  • bronchial asthma;
