Why does chewing a piece of bread develop a sweet taste in a while?

our saliva has an enzyme that reacts with the starch and makes it taste sweet

Digestion is the biochemical breakdown of food into constituents units with the help of hydrdolytic(digestive) enzymes.While chewing, the taste buds send stimulation and the outcome is the secretion of saliva by the parotid, submaxillary and sublingual glands. Saliva contains ptyalin which breaks down polysaccharides into disaccharides.Mucus of the saliva helps degglution( swallowing). In the stomach, gastric glands secrete propepsin which works in the acidic medium. It breaks proteins into dipeptides or peptides.So, in the mouth there is a  partial carbohydrate digestion and in the stomach there is a partial protein digestion. Mastication and churning are mechanical processes.

Things like smoking, alchol, and alot of meat and protene can make you taste a little bitter. You probobly just taste really sweet because you eat alot of vegitables.

Blood cells contain hemoglobin which carries oxygen. When blood breaks down, iron is released and causes a metallic taste in mouth. Bleeding can be from the gums, sinuses or nose. The taste can get especially bad when someone has post nasal drip and the dried blood sticks to the back of the throat. If bleeding gums are the cause there is often bad breath associated with the bad taste.\n\nAnother uncommon reason for a metallic taste in mouth is due to small electric currents in the mouth. When two types of metals are used in two different dental fillings a battery can be created. Some believe that it's due to the mercury leakage from dental silver/mercury fillings.\n\nMany oral or IV medications such as thyroid medicine, penicillin, and lithium can give a metallic taste in mouth. When someone is allergic to a specific food, the food can often be detected even in extremely small amounts. Food allergies, such as with sulfur dioxide, can also cause this. Some gastrointestinal disorders can be aggravated by food allergies and cause burping, dry mouth, thirst, rectal itching and a metal taste. High protein diets can cause benign dietary ketosis. This has also been associated with a metal taste.\n\nChemotherapy, radiation therapy, or cancer itself can cause a metallic taste in mouth. It has also been associated with B 12 deficiency, zinc deficiency, Bell's palsy, Strep throat and Sjogren's disease along with anything that causes dry mouth. \nhttp://www.atlantadentist.com/metallic_taste_in_mouth.html\n\nAND:\n\nA metallic taste in the mouth can be caused by infections of the mouth or teeth, skin conditions that affect the mucous membranes in the mouth such as lichen planus, or other problems, such as Crohn's disease.\n\nA metallic taste also may be caused by a substance present in the mouth. Medications that are chewed, rather than swallowed, may cause a temporary metallic taste at the back of the tongue. Other medications, such as Flagyl, tetracycline, penicillamine, Biaxin, ethambutol, biguanides, or allopurinol, can cause a metallic taste because they get into the mouth through salivary secretions or directly from the blood. http://www.sjmercyhealth.org/110333.cfm

Sweet-ish...it makes it taste different. There are a number of things that can do this...lots of fun to research :)\n\nAlmost forgot...the effects happen after about 1/2 hour & don't last for a very long time...maybe an hour or so...

I am not a professional, but I can tell you what I do know.  Bacteria and yeasts live in people's mouths.   In fact, it is principally yeast that contributes to plaque.  That's why sugary foods are not good for your teeth.  Yeasts feed on sugar.  The more sugar you eat, the more yeasts you will have in your mouth.  If the person who gave you oral sex eats a lot of sugar, drinks a lot of beer (which is fermented with yeast) and has poor dental hygene, he likely has large colonies of yeasts in his mouth, and may have passed on some to you.  If you also have a poor diet and eat a lot of sugar, you are creating an environment in your body that helps these organisms grow.

B, chemical and extracellular. Fungi excrete digestive enzymes into the bread itself, so that the fungi can then suck up the gooey bits of bread and digest it themselves.

It sounds like an allergic reaction to something you've eaten or put on your lips. This happens to my sister whenever she eats anything with nuts inside. It started in adulthood for her, she used to eat them fine before. Keep track of when this happens and write it down what you've eaten or done. Good luck!

To expand on the previous answer, the food getting stale is usually a result of evaporation. The air sweeps in and carries the moisture out, thus leaving your favorite soft snack crunchy.

It's because sugar is addictive.

Water with a use by date is offten stored in plastic.  The plastic slowly melts into the water and after awhile the water will taste like plastic/rubber.  You often get this taste when drinking out of a hose.\n\nI thinking the high setting on toasters is more for Pop Tarts than standard bread.

Upon ingestion, a bitter, acrid, burning taste is sometimes noted.
