Does marinating do anything?

Summary by Krater

This video investigates whether marinading meat works, examining the science behind acid marination and how it affects meat proteins. The video concludes that while marinades only penetrate the outer millimeters of meat, they successfully impart flavor without requiring deep penetration, and suggests marinating for shorter times or diluting acidic marinades to prevent a mushy texture.

Answers: Does marinading meat actually do anything?

• Marinades and brines
• Meat tenderization
• Acid marination science
• pH levels in meat and marinades
• Food science and cooking techniques

Ingredients

• chicken breast
• steak
• tofu
• lime juice
• garlic
• cilantro
• oil
• blue food coloring
• potatoes
• carrots
• maple syrup
• mustard
• salt
• white wine

What it concludes

• Marinades do not penetrate deep into meat, typically only reaching between 1 and 3 millimeters.
• Acidic marinades denature proteins on the outer surface of meat, chemically cooking and softening them.
• Marinades fix flavor into the outer millimeter or two of meat, allowing surface flavors to remain even after wiping or cooking.
• Over-marinating meat in straight acidic juice for too long breaks down the outer fibers too much, resulting in a mushy texture.
• Diluting acidic marinades with water prevents the repulsive mushy texture caused by over-marinating.
