If you have been looking at different ways to preserve your food, you may have come across the term “canning”. This method of preserving foods has been around since the early days of man. It is a great way to store food for later use. In fact, it can be used to preserve food for up to a year! There are many types of canned goods available today, including tomatoes, corn, beans, peas, and many other types of food.
However, there are some foods that do not work well when preserved by this method. For example, bananas will turn brown if they are canned. This is due to the fact that bananas contain a substance called an enzyme called bromelain. Bromelain is a type of protease which breaks down proteins into smaller pieces. When these proteins are broken down into small pieces, they tend to stick together and create a brownish color. This is why bananas turn brown when canned.
One solution to this problem is to add some lemon juice to the food before you put it in the canning jar. This will prevent the bromelain from breaking down the protein. Another option is to add citric acid to the food before you put the food in the jar. Citric acid is a natural preservative which is found in oranges. This will also prevent the bromelain form breaking down the protein.
Another thing to consider when canning is what fruits and vegetables to mix together. Some fruits and vegetables are naturally acidic and will react with each other. These include citrus fruits like lemons, limes, and oranges. This is why mixing orange juice with other fruits like apples or peaches is not recommended. If you want to mix citrus fruits with other foods, you should first add some lemon juice to the fruit mixture. You can also add some citric acid to the mixture as well.
Finally, you need to consider the time frame of your preservation. Bananas and apples will turn brown very quickly once they are exposed to air. This is why you should only keep them in the refrigerator after you have made your fruit salad. This will ensure that they do not turn brown.
