Acids
Numbers that represent an acid on the pH scale
0-6
Numbers that represent a base on the pH scale
8-14
pH nature in our mouth
6.2-7.6
Slightly acidic to basic
Name 2 examples of why we measure pH
Microbial stability, preservative efficacy, Taste, and Odor, Also consistency between batches
Example of an acid made at our company
ACV, Juices, list is endless
Bases release these ions when water
Hydroxide ions
pH nature in our stomach
1.5-3.5 Acidic
pH stands for
potential of Hydrogen
pH nature of lotions
Slightly acidic to neutral
Acids release these ions when dissolved in water
Hydrogen ions
Bases found in everyday life
Baking soda, baking powder, bleach, detergents etc
pH nature of skin
4.7-5.75 Slightly acidic
Ways to measure pH
pH meter and pH paper
Dairy product that uses pH for production
Cheese
One example of ingredients/RM used in our batches to acidify the formula
Citric acid, malic acid, ascorbic acid
Example of a base made at our company
Chlorophyll
Reason for pH nature of stomach
Break down food, kill harmful bacteria
Most accurate pH is measured at
Room temperature
True or False. pH is important for food quality not food safety
False
pH below which most common food pathogens don't grow
4.5
Example of a base we tested today
Egg whites
Reason for pH nature of skin
Keep moisture in, Keep bacteria out
pH Meter measures these ions
Hydrogen ions
2 examples of why pH is important in foods or personal care because
It affects Microbes, Flavor, Texture, emulsion stability, proteins, starches/CHO
