Sulfites are sulfur-containing compounds used for centuries to prevent discoloration and reduce spoilage during the preparation, dehydration, storage
A recent study highlighted that organic acid such as ascorbic acid, citric acid, and malic acid found in unripe grape were responsible for lowering the enzyme
When fruits and vegetables are bruised, cut, peeled, diseased, or
Overall, endogenous AsA content and redox status were linked to differences in the browning susceptibility of potato, and a high level of endogenous AsA prevents browning of fresh-cut potato
Ascorbic acid-2-phosphate (AAP) and -triphosphate (AATP) showed promise for cut surfaces but were ineffective in juice
Once the ascorbic acid gets used up, the oxygen will start reacting with the
Other reductones will react similarly

Each molecule contributes to the prevention of enzymatic browning
Anti-browning agents, such as ascorbic acid (AA), citric acid (CA) and cysteine, have been reported to prevent the browning of fruit and vegetable products (Gunes and Lee 1997)
Yes, you can stop apples from turning brown by immersing them in lemon juice
This will help keep it from oxidizing and the avocado will not absorb the water
This will limit the fruit’s exposure to oxygen and help slow down the browning process
The effect of ascorbic acid [AA (40 mmol L-1)] and oxalic acid [OA (2 mmol L-1)] on browning of litchi fruit was investigated under 5% CO2 + 1% O2 controlled atmosphere (CA) and compared with air Prevent Browning Apples, when cut and exposed to air, darken quickly
Your best bet: Citric acid or potassium bromate
