What is the effect of water on browning of apples?
Salt water slows the dehydration (browning of apples) because it is an acid.
Is squeezing lemon juice on fruit to stop it going brown a chemical reaction?
Squeezing lemon juice on fruit to prevent browning is not a chemical reaction, but rather a physical reaction. The citric acid in the lemon juice slows down the oxidation process that causes the fruit to turn brown by acting as an antioxidant.
Brushing the cut edges of fruit with lemon juice can prevent the darkening efffect that contact with air can cause?
Yes, brushing the cut edges of fruit with lemon juice can help prevent enzymatic browning, which is a reaction that occurs when the fruit's flesh is exposed to air. The acid in the lemon juice slows down this reaction by denaturing the enzymes responsible for browning. Additionally, the vitamin C in lemon juice can act as an antioxidant, further inhibiting the discoloration process.
How does lemon juice preserve foods?
Lemon juice helps slow down or prevent the oxidation of food, but I have heard little about preserving it. Peel an apple and dip it in acidulated water (water and lemon juice) and the apple won't turn brown (for a while).
Why does lemon juice stop oxidation PS really urgent answer tonight 19th May if poss?
Lemon juice contains carboxylic acids as Citric and Ascorbic acids they form a thin layer of metallic citrate or carboxylate which prevents the absorption of water ,carbondioxide and oxygen so further oxidation of metal becomes stopped.
Why does sugar keep cut apples from browning?
Browning is polyphenol oxidase (PPO) react with oxygen which form "Rust" Coating freshly cut apples in sugar can reduce oxygen diffusion and thus slow the browning reaction.
Does juice lose chemical energy or kinetic energy in a freezer?
In a freezer, juice loses kinetic energy as the cold temperature slows down the movement of its molecules. The chemical energy in juice remains constant unless it undergoes a chemical change, such as freezing or thawing, which can affect its molecular composition.
What effect does lemon juice have on catalase enzymes?
Lemon juice does not have much effect on a catalyse enzme. If you were to measure it on a scale of 0 to 3 then it is more than likely going to be a zero or 1/2.
Is drinking bottled water or juice between alcoholic drinks reducing your BAC?
Drinking non-alcoholic drinks and consuming food while drinking alcohol slows the absorption of alcohol into the blood.
What does insulation materials contain trapped?
Insulation materials contain trapped air or another gas that reduces heat transfer by convection and conduction. The trapped air acts as a barrier that slows down the movement of heat through the material, helping to maintain a consistent temperature.
What slows down the evaporation of water from an egg?
The porous shell of an egg acts as a barrier that slows down the evaporation of water. Additionally, the egg's egg white and egg yolk contain proteins that can help reduce the rate of evaporation. Finally, the egg's outer membrane can also contribute to minimizing water loss.
How do you get so fat even though Im not eating enough?
Your metabolism slows down, or to a halt. Your body starts eating at your muscle, not the fat. You contain the fat and lose only muscle.
