1. Microwave ovens mainly use electromagnetic waves to heat food. After electrifying, the electric energy turns into microwaves and is transmitted to food, and the heating effect is achieved mainly through the violent vibration of molecules in food. This is a process from the inside out, and the heating speed is faster than that of the oven.
However, because the high-speed vibration of food molecules will also lead to the rapid loss of water and nutrition, the food heated quickly by microwave oven generally has less water and a dry and hard taste.
2. The heating tubes of electric ovens are almost all exposed design, which mainly uses the heat radiation of heating tubes to heat food. This is a more traditional heating method. Through the high temperature in the oven, heat is transferred from the outside to the inside of the food, and the food is mainly heated by thermal energy.
Contrary to microwave heating. The oven can better retain the original moisture and taste of food during the heating process, and the heating mode from outside to inside can make the food crisp outside and tender inside, and the heating is even and transparent.
Generally speaking, ovens are widely used and cost-effective. If you like cooking and baking, you can buy an oven.
Matters needing attention in purchasing oven
Select the oven type. Electric ovens on the market can usually be divided into three types: automatic type, temperature control timing type and simple type. For ordinary families, it is enough to choose the temperature control timing type, because this type of function is more complete and cost-effective. For families who only bake food occasionally, the ordinary simple type is the most suitable. If you are a family that needs to use different baking cooking methods, you can choose the higher-grade automatic type, which has various baking functions, but the price is more expensive.
2. Select the capacity as required. Generally speaking, it is better to choose a household oven of more than 30 liters. If you already have a baking foundation, you can also choose a larger oven as needed.
3. Check the airtightness of the oven carefully. Good sealing of the oven can reduce heat loss. The oven door is mostly open up and down, so it is necessary to carefully test the lubrication degree of the box door. The door of the box should not be too tight, otherwise it is easy to burn if it is forcibly opened; But it should not be too loose to prevent it from falling off accidentally during use.
4. Look at the material of the oven liner. The materials of the inner container are generally galvanized, aluminized, non-stick coating and enamel. Among them, enamel is better, non-stick coating is easier to clean, and galvanized coating is slightly worse.
