How to judge whether glass cookware can use microwave oven

Ordinary glass bowls cannot be placed in microwave ovens, because they cannot withstand high temperatures, so it is easy to crack and damage the microwave. But if it is a high-temperature-resistant glass bowl, it can be heated in a microwave oven, which can well guarantee the performance of the microwave oven and its own safety.

Microwave cooking instructions

According to the characteristics of the food: the initial temperature of the food, the higher the temperature of the food itself, the shorter the cooking time; the heating time in summer is shorter than that in winter; the adjustment of the amount of food. The amount of food is directly proportional to the heating time. The more food, the longer the heating time; the density and water content of the food; the selection of containers and the arrangement of the food. Generally speaking, a shallow, round and straight-sided container holds food, heating faster and evenly, and should be preferred. Because microwave heats the outer food faster, the thick and thick parts should be placed outwards, and the small parts should be arranged in the middle of the container. It is placed radially in the dish so that the thick part that is not easy to be cooked can absorb more microwave energy.

Heat the glass lunch box for a few minutes

It is generally recommended to heat for 5 minutes. If the glass lunch box is used for heating, the time is too long, it will easily cause the loss of water in the food, resulting in the loss of too much nutrients in the food, which will affect the taste. If the time is too short, the heating is not uniform, and the food will be partly cold. In this case, the time is generally recommended to be about 5 minutes. When heated in a microwave oven, part of the water in the food will evaporate. It is better to add one or two spoonfuls of water before heating.
