Scientists continue to study the benefits of probiotics on the human body, but preliminary research shows that probiotics may aid digestion, reduce inflammation and bloating, and even ease symptoms of lactose intolerance and other maladies.
Parents must guard the health of a child who is lactose intolerant by carefully managing the child's diet to avoid foods that will result in symptoms while providing foods that contain necessary nutrients for the child's health and growth.
This test is not administered to infants and very young children because of the risk of dehydration from drinking the lactose-containing liquid, which can cause diarrhea in those who are lactose intolerant, resulting in dehydration.
Using the liquid form of lactase enzymes, children can add a few drops in their milk, put the milk in the refrigerator and drink it after 24 hours, when the lactase enzymes have reduced the lactose content by 70 percent.
Lactose is thus found to be glucosido-galactose and melibiose a galactosido-glucose.
The fat (which when separated we know as butter) and the lactose constitute the carbonaceous portion of the milk regarded as food.
For example, various sugars - lactose, glucose, saccharose, &c. - are added to test the fermentative action of the bacterium on these substances; litmus is added to show changes in reaction, specially standardized media being used for estimating such changes; peptone solution is commonly employed for testing whether or not the bacterium forms indol; sterilized milk is used as a culture medium to determine whether or not it is curdled by the growth.
Of especial note is the transformation of maltose by maltase into glucose, and of cane sugar by invertase into a mixture of glucose and fructose (invert sugar); other instances are: lactose by lactase into galactose and glucose; trehalose by trehalase into glucose; melibiose by melibiase into galactose and glucose; and of melizitose by melizitase into touranose and glucose, touranose yielding glucose also when acted upon by the enzyme touranase.
Milk sugar, lactose, lactobiose, C12H22011, found in the milk of mammals, in the amniotic liquid of cows, and as a pathological secretion, is prepared by evaporating whey and purifying the sugar which separates by crystallization.
Under these conditions the lactose decomposes into dark-brown fission products, the fat loses its emulsified condition and separates out as cream which cannot be made to diffuse again even by shaking, and the albuminoids are converted into a form very difficult of digestion.
