Difference between alkaline and acidic
Alkaline vs Acidic:
While food is categorized in to many groups, acidic and alkaline prevails two of the top most categories of food. Learning the difference between alkaline and acidic foods is of extreme importance in canning and also in balancing one’s diet as well. While in canning, acidic and alkaline food are processed in different ways, too much of both these types of food can affect the PH levels of urine and also cause disorders such as systemic acidosis and severe alkalosis.
What is alkaline?
Food which belong in the upper half of the PH range which is 7.1 to 14, are normally categorized as alkaline food. The human body needs to absorb 50%-80% of its daily alkaline requirement from food which in turn helps the body to maintain the equilibrium of body’s acid base. Alkaline food can be listed down as certain citrus fruits, watermelons, papaya, mango, grapes, melons, pears, apples, banana, kiwis, peaches, pineapples, cherries, avocados, certain vegetables such as parsley, spinach, okra, broccoli, squash, celery, green beans, carrots, beets, lentils, tomatoes, cabbage, cauliflower, turnips, certain oils such as grape seed oil, olive oil, canola oil and also cheeses, nuts and other things such as goat cheese, hazelnuts, chestnuts, raw sugar, wild rice, etc.
While canning, alkaline food must be processed in a pressure canner in order to heat the food to hotter than the temperature of boiling water and eradicating any harmful substances which can prove hazardous to health.
What is acidic?
Acidic food is categorised as all the food which has a pH less than 7 and thus, they belong to the lower half of the PH scale. An acid can thus be defined as a substance with a tendency to donate hydrogen ions (H+) and is thus defined as a hydrogen donor. It is usually a litmus test which determines whether a solution is acidic or not as an acidic solution is known to turn the litmus paper pink. Some examples for acidic food are blueberries, prunes, cranberries, white bread, pasta, wheat, pork, beef, shellfish, ice cream, peanuts, beer, alcohol, string beans, kidney beans, walnuts, plums, store-bought juices, rye bread, brown rice, organ meats, eggs, cold water fish, pumpkin, eggs, sesame seeds, corn oil, sunflower seeds, fatty dairy products, honey, margarine, lima beans, skinless potatoes, navy beans, pinto beans, canned fruits, oats, white rice, cashews, coffee, pistachios, wine, turkey, chicken and lamb.
In the canning process, acidic food are processed by boiling in a waterbath as it is the recommended way for making acidic food safe.
What is the difference between acidic and alkaline?
The best way to determine whether a certain substance is acidic or alkaline is through a litmus test. A strip of paper coated with Litmus, a purple dye which is made from lichens is dipped in to a solution in order to determine the above factor. An acidic solution is known to make the litmus paper pink whereas an alkaline solution will turn it blue.
Also, food is divided in to acidic and alkaline categories according to their PH range. A food with a PH range of 7 or below and thus belonging to the lower half of the PH scale are considered to be acidic whereas food with a PH range of 7 and above are considered to be alkaline. These food are known to affect the PH range of the urine when consumed. Some examples of acidic food can be listed as certain berries, certain beans and mostly meat products whereas alkaline food can be listed as mostly vegetables with a combination of certain nuts and fruits as well.
The canning process regarding the acidic and alkaline food are also different. While acidic food are processed for canning by boiling in a water bath, alkaline food require to be processed in a pressure canner in order to be canned. This is so because certain properties in certain food must be treated in different ways in order to be processes.
Also, consuming too much alkaline food is said to be causing severe alkalosis whereas an excessive consumption of acidic food causes systemic acidosis. Having an alkaline rich diet is considered as beneficial to health as it is known to reduce the risk of degenerative disorders such as osteoporosis, heart disease, cancers, etc by preventing too much acid from accumulating in the blood stream.
