How to prevent food from cooling down

Preventing food from cooling down can be achieved by using insulated containers, adjusting the packaging method, controlling cooking time, utilizing residual temperature reasonably, and heating in stages.

1. Use insulated containers.

Choose insulated lunch boxes or stew pots with good sealing to contain food, which can effectively delay heat loss. Stainless steel vacuum insulated containers have good insulation effect and are suitable for carrying out. When dining at home, you can first heat the plate with hot water before serving food, or use an electric heating plate with heating function.

2. Adjust the packaging method

Store the main food and dishes in layers to avoid rapid cooling caused by water evaporation. Soup based foods are recommended to be served separately in a thermos and poured with rice before consumption. Large pieces of meat can be cut into thin slices or small pieces to shorten the heat dissipation time. Deep mouthed bowls are more conducive to insulation and have a better covering effect than flat plates.

3. Control cooking time

When stir frying, use high heat and fast frying to reduce heat dissipation time. Stewed foods can extend the juicing time and increase temperature. After steaming food, turn off the heat and continue to simmer for a few minutes to utilize the remaining steam temperature. After frying food, it is necessary to drain the oil and cover it with oil absorbing paper to avoid rapid cooling of the oil and affecting the taste.

4. Reasonably utilize residual temperature

After cooking, the oven can be adjusted to low temperature mode for temporary storage of food. Keeping the rice cooker powered on after cooking can extend the insulation time. Clay pots and pans can continue to dissipate heat even after being removed from the heat, making them suitable for stewing dishes that require insulation. After heating in the microwave, let it stand for two minutes to make the temperature distribution more uniform.

5. Split heating

When multiple people eat in batches, some ingredients can be reserved for secondary processing, such as batch blanching of dishes during hotpot. Soup can be divided into small portions and boiled again as needed. Grilled food can be baked until it is about 80% cooked, and then reheated before consumption. Attention should be paid to oil temperature control when frying semi-finished products again.

Pay attention to adjusting the insulation strategy according to the season in daily diet. In winter, warm the tableware in advance, and in summer, avoid excessive insulation that affects the freshness of ingredients. When choosing insulation methods, it is necessary to consider the characteristics of the food. Leafy vegetables should not be kept warm for a long time to avoid discoloration and flavor change, and starchy foods should be fully heated and sterilized after cooling. Check the sealing of the container when carrying it out, and it is recommended to use leak proof design for soup and other food. Reasonable combination of insulation methods can not only maintain a suitable temperature for consumption, but also maximize the retention of nutrients.
