The lemon juice keeps the apple from oxidizing.
If you are working with fresh fruit and would like to keep it from turning brown, place it in an acidic water bath. That is one-quarter cup of apple cider vinegar or one-quarter cup of lemon juice per quart of water. Mix it together, and as you are slicing your fruit, add it to the water bath. It will keep everything from turning brown.
No. It just becomes a lemon with orange juice inside it. It's still a lemon and its seeds will still produce nothing but lemon trees.
When you put lemon juice on a piece of paper, then place the paper on a heat source, the parts soaked with the juice will burn faster and turn a dark brown. This chemical reaction is based upon the properties that define acids and bases. The paper with the acid lemon juice is weakened by the acid, and will burn faster.
Yes, sugar does dissolve in lemon juice. Lemon juice primarily consists of water, and since sugar is soluble in water, it can dissolve in the acidic environment of lemon juice as well. The acidity of lemon juice may slightly affect the rate at which sugar dissolves, but overall, it will still dissolve effectively.
Apples turn brown when exposed to oxygen, a process called enzymatic browning. Liquids that contain acids, such as lemon juice or vinegar, can help slow this browning process by lowering the pH and inhibiting the activity of the enzyme polyphenol oxidase. Other liquids, like water or soda, don't prevent browning effectively, but can still cause oxidation if they allow oxygen to reach the apple's surface.
Umm it gets sweeter..?
a normal lemon would yield about 3 tablespoons or 45 ml of juice. Inserting a fork would produce a better yield than microwaving it or rolling it against a counter but still a reamer would still be the best.
Yes, lemon juice can react with magnesium ribbon. The citric acid in lemon juice can react with magnesium, producing hydrogen gas and magnesium citrate. This reaction may be less vigorous than with stronger acids, but it still demonstrates the reactivity of magnesium with acidic solutions.
Water can slow down the browning of apples by creating a barrier that limits the exposure of the fruit to oxygen, which is necessary for the enzymatic reaction that leads to browning. However, if apples are not kept submerged, they will still be exposed to air, allowing oxidation to occur. Additionally, moisture on the surface may help reduce browning temporarily, but without complete submersion, the apples will eventually brown due to oxygen contact. To minimize browning effectively, it's best to combine water immersion with other methods, such as adding lemon juice or using airtight containers.
No, it has gone off.
Apples go brown in the presence of oxygen. Boiling means that the apple doesn't come in contact with oxygen.
After you zest a lemon, chances are good that the lemon is still perfectly fine. You can use the juice as flavoring (in tea is really good) atop / in food or in drinks. If you cut the lemon, you can also use it as a garnish.
