Cox Apples

abbysd2000 — 2019-07-24 12:28:58 UTC

96 hours of apples! Using bicarbonate of soda, lemon juice, iron tablets and just water as a control.
I think I labelled lemon juice and control the wrong way round, or these results are quite surprising!

Various Vitamins

2019-08-04 16:42:10 UTC

From left to right: control, vitamin D, vitamin B, multivitamin, calcium and magnesium.

Vitamin c, ferrous sulphate and control

2019-08-10 19:29:40 UTC

Surprisingly although the iton stained the outside inside it was the least decayed while the vitamin c was the most decayed (maybe it was an old tablet though)

Apples after 96 hours

2019-08-12 11:47:38 UTC

I used vitamin D and vitamin C as well as a control of just water. The control and the vitamin D apples went black at similiar rates (D was slightly slower), but the vitamin C apple looks almost as good as day 1!

Control, A-Z multivitamins and vitamin C

2020-07-21 11:34:11 UTC

I was very pleased with my results, the browning of the left spoke clearly shows oxidation, the blackening of the middle apple shows the effect of the traces of crude oil and heavy metal in the A-Z multivitamins and minerals and the unchanged nature and healthiness of the right apple shows the wonderful antioxidant properties of the vitamin C tablets

Braeburn apple after 6 days

miaowkatgirl — 2020-07-26 21:11:24 UTC

Left to right: control, vitamin c tablet and multivitamin tablet.

The control apple had some brown patches and the multivitamin apple blackened, the tablet also seemed to encourage mould growth. The vitamin c apple doesn't seem to have any browning, but the tablet contained a dye which stained the apple red.

Vitamin C vs AZ

2020-08-07 14:03:17 UTC

Control (left) had the most oxidation occur followed by AZ which was very close to Vitamin C and both had virtually no browning happen. Only left for 48hrs if left longer there may have been a more clear distinction between AZ and vitamin C.

Vitamin C Experiment

2020-08-11 14:13:20 UTC

I think this worked really well! Each apple slice was 10g. The slice in just water browned; the slice in Vitamin C did not brown at all (though it took on an orange-yellow colour from the vitamin C tablet!); and the slice in the multivitamin went black within a few hours.

In this experiment five slices of apple were put in vitamin C, E, multivitamins, water and axposed to air for 10 hours.
Results:
You can appreciate in the photo the antioxidant power of vitamins.
The slices of apple that were put in vitamin C and E were the ones that kept their freshness.
The one that got a stronger brown color was the one exposed to air.

The apple in contact with free radicals is clearly deteriorated and presents an orange color (PHOTO 3). On the contrary, the apple in contact with antioxidants retains its yellow color and itself seems to have been preserved (PHOTO 1). The apple in tap water, in contact only with air, also shows a little deterioration on the edges, but not as much as the first (PHOTO 2).

2021-07-24 11:54:40 UTC

I have also come to the conclusion that vitamin C is the most effective antioxidant because throughout the 4 days, the apple placed in water containing vitamin C didn't brown, whereas the one in water (which acted as a control) did and the one placed in A-Z multivitamin water went even black!

from left to right: control, vitamin c and multivitamin. the apple with vitamin c oxidised the least as expected, whereas the apple with multivitamin oxidised the most; not sure if the colour is due to the multivitamin itself or just due to oxidation. - JN
