Aim: I want to find out how long meat can be preserved?

Method: Try to preserve meat with salt, sugar, and honey.

Which of these ingredients will preserve the meat the best?

1. Put 1 piece of beef the size of a potato into a zip-lock bag and then put salt into the bag. 

2. Then put the next piece of beef same size as the last into a zip-lock bag and then put sugar into the bag.

3.Finally put the last piece of beef the same size as the last two into a zip-lock bag and then put honey into the bag. 

Equipment:

• Honey
• Meat
• Salt
• Sugar
• Sanitary Gloves
• Zip-lock Bags/Sandwich Bags

Honey Meat:

Honey Meat

Looked:The Honey meat look like a disgusting piece of juicy meat

Felt: Sticky & Squishy 

Smelt: It smelt like honey

Sound: It sound like a piece of rubbish being scrunched up

1 week later

The meat smelt so bad that I can't can't explain it 

The meat looked like human feces

It felt hard, sticky and squishy

Conclusion:

• Meat must be dry to preserve
• Salt can kill bacteria.
• Salted meat smells better than the rest.

Discussion: 

Why does salted meat smell better than sugar and honey meat?

 Because salt is usually paired with meat.

Why can salt kill bacteria?

Because salt dries out meat.

Why was my meat disgusting?

Because there was still moisture on the meat which caused the smell.

The next part of my investigation is to redo the procedure but hang up the meat.
