The idea from insoluble , from the Latin language (insolubĭlis), mentions what cannot be dissolved . The verb dissolve, on the other hand, refers to undo a compound through the dissociation of its components or, more specifically, to separate the particles that are introduced into a liquid so that they are incorporated into it .
When something can be dissolved, it receives the qualification of soluble . The solubility Therefore, it is a quality of these substances, which dissolve in other materials called solvents .
On the contrary, substances that do not dissolve are mentioned as insoluble. It is important to keep in mind that solubility is linked to various factors, such as Pressure and the temperature .
He oil for example is insoluble in water . If we introduce both liquids in a bottle and shake it, we will not be able to create a homogeneous mixture: we will always notice that the two substances are kept separate. This is because each water molecule has a negative pole and another positive pole, while the oil lacks polarity (it is neutral). In this way, the oil does not dissolve in water since it does not register or repulsion or attraction to its molecules.
The concept of insoluble is also used with respect to that which cannot be clarified or resolved . An economist, to name a case, can argue that the problem of unemployment is insoluble in a region due to the particular characteristics of the market . A sociologist, meanwhile, believes that violence in an unequal society is also an insoluble scourge.
Since this word has two well-defined meanings, its synonyms must be grouped into two separate lists. With regard to the idea that charges in the field of chemistry , we can replace it with inseparable, indissoluble, resistant and firm; for its meaning as "something impossible to solve", we have impenetrable, impossible, irresoluble, incomprehensible and indecipherable. The most used antonym for the first case is soluble; in the second they can be used explicable and decipherable.
This concept also appears in the gastronomic field and is of great interest to experts in nutrition . Talk about food fibers to make reference to a group of components that the digestive system of the human being is not able to digest and, therefore, cause effects of great importance in the organism. They can be divided into soluble and insoluble fibers, according to their degree of water solubility, and each subgroup has different properties.
To know which one suits us in each case and in what food find it, we will see below some relevant data and their main differences. Broadly speaking, we can say that the best known soluble fibers are mucilages, gums and pectins, while insoluble ones that stand out are hemicellulose, lignin and cellulose.
The foods in which we can find insoluble fiber are nuts, grapes, broccoli, cabbage, chard, spinach, seeds , wheat bran and lettuce. Soluble, on the other hand, is present in carrots, citrus fruits, apples and barley.
Insoluble fibers are very effective in controlling the levels of cholesterol in blood, thanks to its union with bile acids to enhance its excretion. Of those mentioned above, the most recommended in this case is lignin. Constipation is another condition that can be treated through the consumption of insoluble fiber.
On the other hand, soluble fiber causes a delay in gastric emptying, thanks to which the period between each meal and the elevation of blood glucose is reduced. Individuals who need to control the glucose level can find an ideal product in soluble fiber.
