Lactic acid, hydrochloric acid and digestion process

lactic acid111 Lactic acid is a natural product that promotes the enhancement of metabolism in humans or animals. The product is biologically safe. Its formation occurs as a result of fermentation of lactic sugars, in particular in milk, wine or beer.

lactic acid222 Lactic acid is actively used in the food industry, it acts as an antioxidant and preservative. It is officially authorized for use, and without any restrictions. Its application is quite extensive:

  • milk processing industry,
  • fish and meat processing, oil and fat,
  • in veterinary medicine it is used as an antiseptic and anti-bodily preparation,
  • it is included in the composition of canned forages to better store them.

Preservative E270 is used in the preparation of

  • solid cheeses,
  • kefir,
  • yogurt and mayonnaise,
  • of other lactic acid products.

It is also used in the confectionery industry and in the production of some non-alcoholic beverages.

Application in the food industry is quite legal, and it can be applied without any restrictions, not only in our country, but also in other European countries.

The value of the product lies in the ability to preserve the freshness of the products for a long period and prevent the development of pathogenic fungi and bacteria in them.

It is allowed to include E270 in products intended for baby food.


is found You can meet it in its natural form as part of fermented milk products. It is formed by kneading and standing a yeast dough. For the preparation, fermentation of the sugar solution and milk waste using lactic acid bacteria is used.

lactic acid333 Product E270, actively used in the food and processing industry, is a representative of a group of carboxylic acids, it looks like a transparent, non-precipitating liquid, has a specific smell and a characteristic acidic taste. Presence of it in the composition of canned food prevents occurrence of processes of fermentation and development of pathogenic microbes.

In living organisms lactic acid is produced as a result of the splitting of glucose, which is a source of energy for the work of muscles and the brain.

The more a person works, the more the amount of it is produced by his body. For an adult male the production of 120-150 g per day is considered the norm. Excess it is excreted through the kidneys.

Lactic acid, hydrochloric acid and digestive organs of a person

Foods that include E270 are especially useful for people who have abnormalities in the digestive system and gastrointestinal tract.

lactic acid As for the process of digestion, the main component of its gastric juice is hydrochloric acid. It is produced by the lining cells of the fundal glands located in the body of the stomach and on its bottom. The concentration of hydrochloric acid produced by the covering cells is about 160 mmol / l, but the acidity of the gastric juice itself can vary due to changes in the number of functioning covering cells. Also, the alkaline components present in the gastric juice, which contribute to the neutralization of hydrochloric acid, have a large effect on this index.

In the human stomach, the presence of other acids is noted, but in very small amounts.

In particular, when carrying out laboratory tests, lactic acid can be found in the human gastric juice. Its appearance is the result of the active vital activity of streptococci, enterococci, lactobacilli and other types of lactic acid bacteria. All of them can exist only if there is no hydrochloric acid in the stomach.

Thus, in the case of detection in the gastric juice of lactic acid indicates a significant decrease in production in the stomach of hydrochloric acid, or even its complete absence. The detection of lactic acid in the stomach contents may be a symptom of a progressive cancer of the stomach.

But the real picture and a correct assessment of the patient's condition can be obtained only if the state of acidity is determined simultaneously in different parts of the esophagus, stomach, duodenum. Diagnosis of the disease can only be if there is information about the change in acidity in time, the graphs of these changes, their dynamics after taking medications and the necessary stimulants.
