The term juice comes from the Latin word sucus. The concept refers to liquid of vegetable or animal origin that is obtained by distillation , cooking or Pressure .
Juice is usually used as a synonym for juice , which is a fluid generated by squeeze or crush a fruit, a flower or something similar . Juices or juices are very important in food.
The fruit juices For example, they are popular all over the world. These juices are extracted by pressing or liquefying a fruit , such as orange, grapefruit, grape, lemon or apple. Natural juices, squeezed from fresh fruit and without the addition of preservatives, have beneficial nutritional properties for the body.
Because of the difficulties of getting and squeezing fresh fruits every time you want to drink juice, it is common for people resort to packaged fruit juices . In this case, the product goes through various processes and has additional substances that make them no longer so positive for health.
He vegetable juice It is another healthy alternative, although less consumed than fruit juice. He carrot juice and the beet juice (beet) are two of these options .
It is called gastric juice , on the other hand, to a combination of secretions of the gastric glands that is formed with sodium chloride, hydrochloric acid, water, potassium chloride, mucus, enzymes and bicarbonate. This fluid allows the bolus of food to be transformed into quimo , a paste whose ingredients are absorbed by the body and its wastes, expelled.
In other words, we can define gastric juice as a combination of secretions of the different specialized epithelial cells. Two other names he receives are Gastric acid and, the most technical of the three, secretion gastric.
In fasting, gastric juice consists of a solution of sodium chloride with potassium and hydrogen in small amounts. Once we eat food, the concentration of hydrogen increases to considerable levels and that of sodium decreases until about 2 liters of hydrogen chloride are produced with a pH whose value minimum is 1.
It is important to note that a pH of value 1 is three million times lower than that of blood. Chloride secretion takes place against the electrical gradient and against the concentration. In this way, parietal cells have an ability to secrete acid which is linked to active transport.
Gastric juice secretion is the most important stage of the digestion , since when the food bumps into the lithic enzymes and with a low pH it dissociates into collagen fibers and the phenomenon known as proteolysis, that is, the proteins present are denatured. At the same time that the stomach contracts and produces a mechanical action, what is mentioned above constitutes the chemical action.
The mucus is a slippery and viscous gel that we find as a coating of the mucous surfaces of the stomach and the intestine The gels called mucins, formed by glycoproteins, are what gives them their characteristic features.
In the gastric juice we find several enzymes, but the most important is pepsin, which can be defined as a heterogeneous protein group that has the function of denaturing proteins. Among the others, which have well-defined functions, the gastric lipase also stands out, with great effectiveness against triglycerides with fatty acids whose chain It is jelly and short.
In the symbolic sense, finally, it is named as juice the useful or profitable from something , either immaterial or material: "Let's get juice this weekend!", "I'm going to try to get the most juice out of tonight's talk.".
