Many white-collar workers are people who bring rice to work. They put the love bento in the microwave to heat it up and enjoy it in a few minutes. However, colleagues who bring meals to work may also bring some health risks. Not to mention whether the overnight meals are healthy, there are also many health hazards in the office hot meal appliances. So, which electrical appliance is better to use for hot meals in the office, and which one is better between a steam oven and a microwave oven? Below is the detailed answer for you. 1 What electrical appliances are used for hot meals in the office? Kitchen appliances? Heating speed? Nutritional health? Radiant intensity? Function? Energy consumption compatibility? Advantages? Disadvantages? It can ensure the molecular structure of the food itself, ensure the original taste of the ingredients, and cook the food with natural water vapor. There is no radiation hazard. It cannot meet the production needs of barbecued food. The energy loss is low. Microwave ovens use magnetrons to generate heat, the heating speed is fast, the water and nutrients are lost, and the taste is not good. Microwave food may produce toxic and carcinogenic compounds. When heating food, radiation will be generated, causing greater damage to the human body. Microwave ovens can be used for barbecue food And puffed food consumes a lot of electricity and energy consumption. Iron and aluminum containers cannot be used for heating and heating. Nutrition is reduced or even carcinogenic substances are generated. The electromagnetic radiation large light wave furnace is heated by the principle of far-infrared heating, and the heating speed is very fast. It can quickly cook and maintain the heating efficiency of food nutrition. The high heating time is short, the damage to the food structure is extremely limited, and the light wave oven still has electromagnetic radiation, which is compatible with the function of the microwave oven. The use of metal or metal container lightwave ovens is an upgraded product of microwave ovens. Compared with microwave ovens, it has the advantages of energy saving, health, convenience and practicality. 2 Differences between steam ovens and microwave ovens
1. How to heat foodDifferent types:
The steamer heats the food by pure steam heating, and the heating speed is slow; The molecules inside the food vibrate at high speed to generate heat, but it heats up faster.
2. Food health and nutrition Different:
Steamer It is carried out in the form of heat transfer, without destroying the molecular structure of the food itself, steaming the food in a short time, inhibiting the loss of food nutrients, preventing oxidative deterioration, and maintaining the original taste of the food. The food heated by the microwave oven will lose the original moisture in it, which will cause the hot food to have a dry feeling, which cannot guarantee the nutrition of the food and the original taste of the food.
3. Radiation intensityDifferent:
It is determined by the steam heating principle of the electric steamer itself, and the product uses water steam to cook food. It is an independent body, there is no light wave, microwave, and there is no radiation effect on the food inside and outside. The magnetron of the microwave oven produces radiation not only to the food itself, but also to the surrounding people when it is working.
4. Different functions:
Microwave ovens can be used for barbecue, popcorn, but steam oven If you can’t do it, each has its own advantages in terms of using functions.
3 Are steam ovens easy to use?
1. Look at temperature controlControl:
It is divided into two aspects: temperature adjustable range and temperature control accuracy. Temperature adjustable range: the range of maximum and minimum temperature to be adjusted. Temperature control accuracy: the consistency of the adjusted temperature range with the actual temperature change.
Expert advice:
The biggest difference between the steamer and ordinary steaming tools is that the temperature of the steamer can be adjusted. , such as dough fermentation, homemade yogurt can be achieved with a steamer. For the steamer, the temperature control accuracy is the most important indicator. Whether the food tastes good or not and whether the nutrition can be completely preserved depends on the temperature control accuracy. Therefore, when purchasing a steamer, we should not only pay attention to the adjustable temperature range, but also pay attention to the accuracy of temperature control, so as to steam nutrition and steam health.
2. Look at heatingHeating method:
It is divided into drip heating and independent water tank heating, heating The way affects the cooking speed. Drip heating: There is a heating plate at the bottom. When working, water flows out from the drip port of the plastic water tank and drips on the heating plate, and then heats up to generate steam. Independent water tank heating: There is a heating pipe inside the water tank. The divider of the water tank divides the water in the water tank into two. The heating pipe first heats a small amount of water in it to generate steam for cooking, and there is a small channel at the bottom of the heating cavity. When the amount of water inside decreases, water from the outside slowly flows in to replenish.
Experts suggest:
Drip heating method, the steam generation is very unstable, because the speed of dripping water is difficult to control accurately, when there is no water dripping, there will be no steam generation, at this time The temperature is low. When the water drips down, a large amount of steam is suddenly generated, and the temperature in the box fluctuates suddenly, which is very unstable, and the taste of the food is much worse. The heating method of the independent water tank, the water tank is not only a water storage container, but also has a heating tube inside, which can quickly boil water to generate steam for cooking, and steam can be generated within 2 minutes, which greatly speeds up the cooking speed and saves time. .
3. Look at the steamIntake and exhaust:
It mainly depends on whether the steam box has an air intake and exhaust breath. Air inlet: the inlet of fresh steam. Exhaust port: Exhaust port for excess steam.
Experts suggest:
If there is an air inlet but no air outlet, there is no steam in and out of the circulation, and the steam is easy to be too much, and it is difficult to ensure an accurate and constant temperature. There are air inlets and air outlets, which can ensure the continuous circulation of air intake and air outlet, maintain a dynamic balance, so that the steam is always evenly distributed, the temperature is more constant, and the food is not overcooked or undercooked. Unpleasant smell.
4 What is the difference between a microwave oven and a microwave oven
(1) Heating methodDifferent styles
1. Grilling inside the microwave oven The tube is a magnetron, a microwave generator that generates microwaves that vibrate 2.45 billion times per second, which heat food from the inside out. The barbecue tube of the microwave oven generally uses a copper tube or a quartz tube.
2. The light wave oven is also called the light wave microwave oven. The barbecue tube of the light wave oven is replaced by a quartz tube or a copper tube with a halogen tube (ie, a light wave tube), which is heated by the principle of far-infrared heating. Heat food from outside to inside. The light wave oven also cools quickly, heats more efficiently, and does not burn, thus ensuring the color of the food.
(2) Differences in production costs
1. The cost of copper tubes used in microwave ovens is slightly cheaper .
2. The cost of the light wave tube used in the light wave furnace is only a few yuan more than the copper tube or the quartz tube.
(3) FunctionsDifferences
The biggest difference between light wave microwave ovens and ordinary microwave ovens lies in the A light wave emission source is installed inside, so that the electrical appliance has the important function of light wave heating. At the same time, using light waves and microwaves to heat food will better protect the nutrition of the food, and at the same time, it will have a faster and energy-saving effect. In addition, for people who like grilling food, a microwave oven product with light wave function can easily complete the task of general grilling food, and is faster and more environmentally friendly than ordinary electric ovens.
5 Which is better, a microwave oven or a microwave oven?
In fact, most of the light wave ovens on the market are light wave microwave ovens. The light wave microwave combination oven greatly improves the heating efficiency of microwave ovens and light wave ovens. These two different heating principles are used at the same time to heat together. High-speed cross-heating of food in a closed oven cavity completely solves the phenomenon of uneven heating and uneven cooking in microwave ovens in the past, and the thermal efficiency is higher. And to maximize the nutrient content of the food during the cooking process, avoid to minimize the loss of moisture when cooking the food. The light wave is an auxiliary function of the microwave oven and only works on the grill. Without a microwave, a microwave oven is only equivalent to an ordinary oven. The lightwave ovens on the market are all lightwave and microwave combined ovens. In use, they can be operated with microwaves, alone with lightwaves, or in combination with lightwaves and microwaves. That is to say, the light wave oven is compatible with the function of the microwave oven.
6 Differences between electric steam ovens and steam microwave ovens
Electric steam ovens are a new type of kitchen appliance that has only become popular in recent years. There are many microwave ovens with steam function on the market today, but microwave cooking makes food watery. And the loss of nutrients is too large, and the taste is not good. The electric steam oven does not have the problem of water loss at all. Electric steam ovens have many advantages over microwave ovens, but they are also relatively expensive.
1. Heating methodsDifferent:
The electric steamer is heated by steam heat transfer; The magnetron used in the microwave oven generates high frequency, which makes the molecules inside the food within a certain range vibrate at a high speed to generate heat. There are three main ways of cooking in steam microwave ovens. They are the steam turntable method, the steam jet turning wave method, and the steam turning slope method.
2. Healthy food Different nutrients:
Because the electric steamer is transferred by heat The form is carried out without destroying the molecular structure of the food itself, so that the food can achieve its original taste. Therefore, the degree of damage to the nutrients of the food processed by the electric steamer is lower than that of the products processed by the microwave oven.
3. Radiation intensityDifferent:
It is determined by the steam heating principle of the electric steamer itself, and the product uses water steam to cook food. It is an independent body, there is no light wave, microwave, and there is no radiation effect on the food inside and outside. The magnetron of the microwave oven produces radiation not only to the food itself, but also to the surrounding people when it is working.
4. Environmental protection and electricity saving Different degrees:
It is generally ten times for an electric steamer to process a dish minutes (power consumption is 0.2-0.3 degrees), which is more time-saving and power-saving than microwave ovens. Disadvantages of electric steam boilers: expensive.
7 How to eat healthy meals for office workers
(1) Do not bring overnight mealsdishes
1. Eat overnight lunches The risk of stomach cancer was 3.6 times higher. Because the overnight vegetables are cooked for a long time, the nitrates will be reduced to nitrites under the decomposition of bacteria, which has a carcinogenic effect and cannot be removed by heating.
2. First of all, rice (staple food) and dishes should be served separately and not mixed together. Mixed meals are more conducive to bacterial growth. Secondly, “leftovers can’t be brought. Leftovers are usually touched by multiple pairs of chopsticks, and there is saliva in the dishes. The saliva in the dishes will cause the dishes to deteriorate, or even mildew, which is harmful to the body.
(2) Pay attention to the preservation of the foodStorage time
The lunch box food is really fresh only for two hours. Since you can’t eat overnight dishes, then Is it okay to cook in the morning? Many people tend to ignore the preservation time. The temperature in the car, the time spent on the road, the temperature and time of the company’s placement, etc. will affect the meal when the prepared lunch box is taken to the company. Freshness and nutritional value. The United States has clear regulations for the food industry: food stored at room temperature should not exceed 4 hours, and the longest time of food stored in refrigeration is only 6 hours. According to the requirements of scientific and healthy diet, the food should be cooked after cooking. It must be eaten within 2 hours under normal temperature conditions, and must be discarded for more than 2 hours.
(3) The rice box is best made of porcelain High quality or glass material
Porcelain fresh-keeping box is the first choice. Porcelain has high temperature resistance and natural ceramic ingredients, which is relatively safe. Glass material lunch boxes are also acceptable. Stainless steel lunch boxes are not suitable. If you use inferior stainless steel lunch boxes or Inappropriate use of stainless steel lunch boxes may cause heavy metal hazards. In addition, aluminum lunch boxes are also unhealthy, because aluminum is an element of intellectual aging, and excessive aluminum accumulation in the human body will cause arteriosclerosis, osteoporosis, and dementia in the elderly. If it is a plastic box, there is a triangle with a “5” in the bottom of the box, and “PP” (abbreviation for polypropylene) is also written under the triangle, it can be heated in a microwave oven, and plastic lunch boxes suitable for microwave ovens can also be used.
