For the first apple slice, firstly, clean, peel and core the apple, cut it into small pieces with a thickness of 0.2 cm per month, soak the cut pieces in water, and squeeze a few drops of lemon juice in the water to prevent the apple slices from oxidation. After 20 minutes, take out the apple slices and put them on the baking tray covered with tin foil, so that the distance between the slices is as large as possible, then put them in the oven and bake at 100℃ for one and a half hours. Crispy dried apples are ready, fresh, natural and healthy, without any additives.
The second is banana slices, similar to the production process of apple slices. Peel and slice bananas first, and put them directly into 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 them at 40 degrees Celsius for 45 minutes, and then bake them at 100 degrees Celsius 10 minutes. Bananas are rich in nutritional value, and moderate consumption can play a laxative role.
The third kind is pineapple slices, peeled, washed, cut into small slices within 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. They can provide a lot of energy for human functional activities and are beneficial to diabetics. First, the raw purple potato is washed, peeled and cut into 5 mm slices, then the water in the slices is dried, and then these slices are laid flat on the plate one by one, and the slices should not be next to each other to avoid adhesion. 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 plate are slightly white. Poke the chopsticks to see if they are ripe, 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), and 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 the three types of dried fruits, namely, fruit and vegetable chips, 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 a lot of added sugar, so the heat is very 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 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 diet, it is far better to treat dried natural fruits without additives as snacks than all kinds of high-fat and high-sugar biscuit cakes. Although dried fruits are relatively healthy, don't eat more. The Dietary Guide for China Residents suggests 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.
