For the first apple slice, firstly, the apple was washed, peeled and the inner core was removed, and it was cut into small pieces with a thickness of 0.2 cm per month. The cut pieces were soaked in water, and a few drops of lemon juice were squeezed in the water to prevent the apple slice from oxidation. After 20 minutes, take out the apple slices and put them on a baking tray covered with tin foil, so that the distance between the slices is as large as possible. Then put the baking tray into the oven and bake at 100 degrees Celsius for one and a half hours. Fragrant and crisp dried apples are ready, fresh, natural and healthy, without any additives.
The second is banana chip, which is similar to the process of making apple chip. First of all, peeled and sliced bananas can be placed directly in a baking tray covered with tin foil without soaking. Then, sprinkle some sugar evenly on the banana slices, and then put them in a baking tray for baking. However, unlike apple slices, you have to bake at 40 degrees Celsius for 45 minutes, and then bake at 100 degrees Celsius for 10 minutes. Bananas are rich in nutritional value, and can play a role in defecation when eaten in moderation.
The third is pineapple slices, which are peeled and washed, cut into small slices below 1 cm, placed in a basin filled with warm water, sprinkled with a little salt, stirred slightly, and soaked in salt water for 20 minutes to remove astringency. Take it out after 20 minutes, drain it, put it in a baking tray and bake it in an oven at 70 degrees Celsius for two hours. Friends who like hard and crisp can extend the baking time.
The fourth is purple potato chips, which are rich in starch and low in fat, and can provide a lot of energy for human functional activities, which is beneficial to diabetics. First, clean the raw purple potato, peel it and cut it into 5 mm slices, then dry the water in the slices, and then spread these slices on the plate one by one, so as not to stick together. Then put the plate in the microwave oven for heating, take it out after two minutes, turn the other side over, put it in the microwave oven for heating, and take it out again after two minutes to check whether the two sides of the sheet are slightly white. Poke the chopsticks to see if they are cooked. That's enough.
Are fruit and vegetable chips nutritious?
Experts say that the real dried fruit is the natural state after the fruit is dried and dehydrated, without adding sugar, salt, oil and any food additives such as jujube, raisins and dried longan. Compared with fresh fruit, dried fruit lost some water and vitamins (such as vitamin C), but also concentrated minerals, dietary fiber, antioxidants and other components. Therefore, when you can't eat cold foods such as colds and coughs, you can use dried fruits as the "body body double" of fruits.
However, not all dried fruits are healthy. Experts say that crisp fruits and vegetables, preserved fruits and candied fruits are not "concentrated fruits". The dry fat content of natural fruits is mostly below 1%, while fruit and vegetable chips are usually fried at low temperature, not only the fat content is as high as 10% to 20%, but also the nutrients such as vitamins are almost lost by frying. Preserved fruit takes fresh fruit as the main raw material and ingredients such as sugar or honey. In addition to the sugar of the fruit itself, there are many added sugars, so the calories are high. Sour and salty preserves are the most unhealthy. Because they need to add a lot of sugar and salt in the production process, such as the most common preserved plum, dried tangerine peel, additives, Chen Pidan and so on. The sodium content is generally above 500mg/ 100g, while the standard of sodium intake stipulated in the Dietary Guidelines for China residents is no more than 2300 mg per day. Some candied fruits have many additives.
Experts suggest that from the perspective of dietary collocation, it is far better to treat dried natural fruits without additives as snacks than all kinds of biscuit cakes with high fat and sugar. Although dried fruits are relatively healthy, don't eat more. The Dietary Guidelines for China Residents suggest that you can eat 200 to 350 grams of fresh fruit every day. If you occasionally use dried fruit instead of fresh fruit, try not to exceed 30 grams a day.
