Research

This is all of my research for my question - Does the pH of saliva affect the taste of food'?

This is the pH scale and examples of substances which are of that pH level.
1-6 = Acidic, 7 = neutral , 8-14=alkaline

pH1= Hydrochloric Acid
pH2=Lemon Juice,Gastric Acid,Vinegar
pH3= Grapefruit,Orange Juice, Soda
pH4= Tomato Juice, Acid Rain
pH5= Soft Drinking Water, Black Coffee
pH6= Urine , Saliva
pH7= Pure Water
pH8= Sea Water
pH9= Baking Soda
pH10= Great Salt Lake, Milk of Magnesia
pH11= Ammonia Solution
pH12= Soapy Water
pH13= Bleach, Oven Cleaners
pH14= Liquid Drain Cleaner'

Saliva usually has a pH chemical level of between 6.0 and 7.4.

You need saliva to taste food because enzymes dissolve the chemicals in food and only then can you taste the food.Enzymes is a substance contained in saliva that dissolves the chemicals in food.

Many researchers say that the pH of your saliva does affect the taste of food. This statement is correct because when you brush your teeth using toothpaste which has a pH level of ph8 - ph9 which is alkaline and then you drink some orange juice which has a pH of 3 - 4 the taste is extremely different from when you drink it when the pH of your saliva is neutral.
