Do you bring food sour in a thermos cup in summer? Is it not good to use insulated lunch boxes in summer?

In daily life, many people often eat lunch in insulated boxes, especially office workers and students. In summer, the weather is hot and the temperature is high. In general, it is not suitable to use an incubator for lunch in summer. It's hot in summer, so it's easy to spoil rice and breed bacteria with heat preservation boxes. Therefore, it is best not to use an incubator for lunch in summer. Let's take a closer look!

1. Will the rice in the thermos turn sour in summer?

It's hot every day in summer, so it's easy for food to go bad outside, not to mention it's stuffy in a thermos. If the food cooked in the morning is put in a thermos bucket, it is not easy to deteriorate, and even if it is not put, it will breed a lot of bacteria.

2. How to prevent corruption?

Put rice and vegetables into the liner of the insulated lunch box, put the liner into the freezer of the refrigerator, put the liner with food into the insulated lunch box the next morning, and then put it into the insulated bag. After half a day, the frozen food has not completely melted, so it can be heated by microwave oven at noon.

3. Pay attention to bring food with a heat preservation barrel.

1. In order to prevent food from going bad, it is best to cook the food at noon that day in the morning, and put the cooked food into a heat preservation barrel after the temperature drops. If the unit has a refrigerator, it is best to keep the food in the refrigerator.

2. The food taken out of the freezer should be heated to 100 degrees Celsius before eating. The heated food should be eaten within 2 to 3 hours. If stored at room temperature for more than 3 hours, bacteria will multiply in large numbers, and diarrhea, vomiting and other discomfort symptoms are easy to appear after eating.

It is better to separate rice from vegetables, because food will affect each other and accelerate deterioration, especially after rice is soaked in vegetable soup.

4. Precautions for food heating

1. Choose products suitable for microwave heating for lunch boxes used for food. Plastic lunch boxes are easy to smell after heating and cannot be used; Some lunch boxes are made of PP and can withstand the high temperature of 200°c, but if the lid and sealing ring are made of PE and silicone, they are not suitable for heating. Therefore, if the lunch box for heating is made of PE and PVC, it is best not to buy it, which will produce toxic substances after heating. Choose a special lunch box for microwave ovens.

2. When the food is heated, cover the lunch box to prevent excessive evaporation of water. The heating time is controlled at about two minutes. If the food is not hot enough, you can heat it slightly for half a minute to one minute.

5. What food goes bad easily in summer?

(1) bean products

The protein content of bean products is high, but it is easy to turn sour at a slightly higher temperature.

(2) Green leafy vegetables

Green leafy vegetables contain nitrate, which can be easily converted into nitrite if stored for too long or heated by microwave oven, which is a carcinogen. And vegetables taste bad after repeated heating.

(3) Fish and seafood

Fish and seafood stored for a long time are prone to produce protein degradation products, resulting in impaired liver and kidney function, and cannot be stored for a long time in summer.
