1. You can soak the apple in salt water, spray some white vinegar on the surface of the apple, and brush some honey on the surface of the apple to prevent the oxidation reaction on the surface of the apple from contacting the air, thus ensuring that the color will not turn yellow. Go to the sun when the weather is very hot, and don't let the apples have water on them, so that the dried apples won't change color.

2. In order to prevent the apple from discoloring, it needs to be baked in an oven preheated to 180-200 degrees for 10 minute. In order to add baking nets to evaporate water, the water on the surface of apples will wrinkle or become smaller after evaporation. Adjust the oven to 100- 120 degrees, bake for 30 minutes, and then take it out of the oven to cool. Low-temperature baking is to dry the water in apples. If the temperature is too high, the surface is easy to zoom, and the burnt apple slices are bitter and unpalatable. Put it in a fresh-keeping box and soak it in cold storage for one day. One day later, take out the pineapple slices and put them on the shelf, with a hot plate under them, and bake at 200 degrees Fahrenheit for about 3-4 hours. It was dry when I went out, but it was still soft in the middle.

3. To dry the apple slices, prepare a big basket. Sprinkle apple slices on the basket and put them on the indoor balcony for 2-3 days. During the drying process, turn the apple slices over every few hours and rotate the basket to ensure that each apple slice is evenly dried. Don't peel the dried apples. Before making, be sure to clean up the pesticides and dust that may remain on the apple skin with a small toothbrush. Key points: One advantage of making dried apples without peeling is that dried apples with apple skins taste more chewy and fragrant after drying.

Dry apples must choose sunny and dry weather. Autumn and winter in the north are especially suitable. Before drying, watch the weather forecast in advance to ensure that the weather will be fine in the next three days. When it rains on cloudy days, dried apples will be moldy and hairy. However, some friends recommend using a fruit dryer or oven, which is fast and convenient. These are also good choices.
