acetic and citric (1 Viewer)

[Steven12]

what did you guys write for acetic and citric acid?

i put acitic acid is used in vinegar for food flavouring and citric in orange juice. man i am doomed aint I?

 

[sub]

acetic is vinegar isnt it? its for preservation of the food, cos bacteria's die...and not harmful to humans cos its weak acid.
correct me if im wrong

 

[tennille]

acetic acid and citric acid are used as food acids to make the food have a sharper taste. Citric acid can be used as an antioxidant, preventing the oxidation of food. microbes cannot withstand an acidic envronment, hence, these acids act as a preservative.

 

[Steven12]

you are, but i am just not what citric acid is for, i mean which part of the F_(*king syllabus was that in?

 

[tennille]

the third section of the acidic environment thing. secondary source.

 

[The Bograt]

They can be added to food to alter it's taste, or provide a chemical reaction to achieve texture (BS). Also used to preserve food since some bacteria and microbes cannot live in an acidic environment.

yeah, i said the sharper taste too...but how many ppl add citric acid to stuff? i kno ppl do for acetic. i sed makes the food more sour? is that right?

 

[KungPow]

I didn't refer to them specifically. I just talked about them both as a whole, compared to HCl

 

[L45er]

Yeh citric acid is in heaps of foods.
I just cranked out the name of the organism (Clostridium Botulinum - trying to impress...lol) which can release deadly toxins into food. But it can't live in acidic conditions, hence thats is why they are used.

 

[tennille]

jeez, i should have made up my own words- then maybe i could have gotten away with it. "ldnfiererhfutos bacteria can create stuff that kills...". I wish i did mention bacteria...then that might impress the markers to give a decent result. But its too hard to remember... hehhe

 

[The Bograt]

hehe when I was talking about cationic detergents I busted out with cetyl trimethyl ammonium bromide

 

[tennille]

lol...i rkn people could get away with that...

 

[golferjim]

i put that both the acids aid digestion as the stomach works best in acidic environments(HCl)

 

[bloodysunday]

yeah i put all the flavouring and preservative stuff plus i said that you could make esters out of the acids which are good flavouring additives

thats not what the q asked was it??

 

[tennille]

it said something like describe the use of acetic acid and citric acid as a food additive...something like that.

 

[tennille]

actually, it says "explain the use of acetic and citric acids as food additives"

 

[sub]

so writing abt esters and shit is not expected right? cos i din do taht

 

[scruffy012]

acetic is ethanoic acid

i put that they are used to preserve the foods so that they would last longer and kill bacteria and some crap like that.

yeah thats similiar to what i wrote, and i wrote that citric was used for something.............. i duuno what


scruffy

 

[tina_goes_doo]

I said they were used as preservatives and as a food additive due to its "sour" taste. Very lame and was the last question i did.
