Frequently Asked Questions
Why does lemon juice prevent browning of cut fruits and vegetables?
Browning results from oxidation of compounds in fruits and vegetables. The acidic environment of lemon juice (pH ~2) slows oxidation. Additionally, vitamin C in lemon juice is an antioxidant that prevents the browning reaction by reacting with oxygen first.
Is all vinegar the same, or do different types have different acidity?
Different vinegars have varying acetic acid content. Distilled white vinegar is about 5 percent acetic acid. Apple cider vinegar is similar. Balsamic vinegar from Italy may be less acidic but has complex flavors. The acidity affects preservation strength and flavor profile.
How do antacids work to relieve stomach acidity?
Antacids contain bases like calcium carbonate or aluminum hydroxide that neutralize excess stomach acid through acid-base reaction. This raises pH of stomach contents, reducing irritation. They do not reduce acid production, only neutralize existing acid temporarily.
