Aim:
I want to find out how lang meat can be preserved.
Method:
Try to preserve meat with honey,salt,sugar
and vacuum sealing.
1. Take three pieces of meat and add some honey to the first one, sugar to the second one and salt to the third.
2.Put all three pieces in plastic bags with zip-lock.
3.Keep meat in the bags for one week.
4. By the end of the week see which piece of eat is in a better condition.
Equipment:
- 3 pieces of meat (beef, 2 x 10 cm)
- honey
- sugar
- salt
- 3 plastic bags with zip-lock.
Observations:
After one day of experiment - The salty piece of meat smells rotten. It's colour is brown.
One week later - The piece of meat with honey looks the worst and also smells the worst. It looks sticky and has a terrible smell. The one with salt looks and smells the best.
The answer to this is that salt kills bacteria and it also dries meat, so bacteria can't spread.
Conclusion:
The experiment has shown that the salt preserves meat better than honey or sugar. Salt dries out the bacteria, that is why bacteria disappears. Next time we should try to preserve meat in different amounts of salt to see how much salt is needed to dry out bacteria.
Hi Rojan-I really enjoyed reading your post. What I liked is that how you use that picture in your post,And explained all the steps of the experiment.Next time you should write about the results of the experiment a little bit more. :)
