Microwave oven

Kitchenaid microwave-ovens are an essential part 微波爐 households and you should know how to take preventive steps in order to properly maintain the microwave oven. This article talks about some basic tips to take care your microwave oven.

Tips To Look After Your Kitchenaid Microwave Oven

o Always cover your food placed in the microwave oven with a covering dish, paper towels or wax paper. This would avoid spatters and keep your oven clean. If there are any spills, they should be cleaned at once and you should regularly wash your microwave oven with a mild detergent and water. While cleaning the oven, do not use abrasive products.

o To remove any odor, you can use a solution of baking soda and warm water to clean the interior of the microwave oven.

o Never use your kitchenaid microwave-ovens for deep-frying, boiling eggs or heating of infant bottles.

o Be very careful while making popcorn in the microwave as there is huge heat buildup inside the oven which can even cause a fire. Follow the exact cooking time as prescribed on the pack; it is better to stick to lower range as higher wattage of the oven can cook the food faster.

o It is very important for you to use only microwave safe bowls and utensils. Some kind of plastics tend to melt inside microwave-ovens, so it is better to use glass utensils to heat food that is going to take longer time to heat. Also, not all glass and ceramics are safe to use inside microwave-ovens. You can take a quick glass test – heat the container in a microwave for one minute. If the container remains cool it is perfect for cooking. If it becomes slightly warm then the container can be used for reheating. If the container becomes hot it is not safe to use it inside microwave oven.

o Do not ever operate empty kitchenaid microwave-ovens as it can sometimes damage the magnetron tube.

o If you find that the inner body of the microwave has developed rusting then it is better to get it checked and repaired by a reputable servicing company.

o Always stick to the instruction manual provided by the manufacturer for operating the microwave oven safely.

o There are some concerns over the use of microwave oven by pacemaker patients because some earlier models of heart pacemakers were found to be interfering with electromagnetic radiations from microwave-ovens. Though the recent technologies have prepared safe pacemakers against such interference, it is still be advisable to consult your doctor if you use a pacemaker.

o For uniform cooking of food, it is better to follow the directions included in the recipe and periodically turn and stir the food while cooking. It is also better to let the food stand after cooking which aids in heat dispersion inside the food.

o Try to avoid metal pans and aluminum foils inside microwave-ovens as they can reflect the microwaves and result in uneven cooking.

Microwave ovens have become an indispensable part of our kitchens. They help in reheating leftovers, defrost frozen foods and make some exciting dishes to impress our guests. Microwave ovens are available in variety of sizes. If you have a bigger family it would be advisable to invest in a large microwave oven so that you would be through with the cooking job in one go.

Over the years, though the popularity of the microwave ovens have increased manifold, still there are some questions over its safety. There are many myths prevalent regarding large microwave ovens and microwave ovens in general. This article gives you the right information and helps you clear your doubts.

The Most Commonly Asked Questions About Large Microwave Oven

o Is heating food in plastic containers dangerous?
Yes, sometimes you would not be able to judge the authenticity of the plastic product that can be used inside a microwave oven for cooking food. When heated at higher temperature continuously, plastic tends to release toxic materials that may harm our body. So, it is always better to avoid plastic containers and instead use glass products for microwave cooking.

o Is the electromagnetic radiation leakage in the microwave ovens unsafe?
This is a common myth that microwaves tend to leak dangerous levels of electromagnetic rays. The standardized products specification requires that all microwave ovens should be equipped with some kind of interlocking systems that automatically stop the production of microwaves the moment the door is opened. If you want to be extra cautious you can stay away from the large microwave oven when in use since microwave energy decreases significantly as you move away from the source. And if you feel you are at danger from microwave ovens then you should start abandoning all the products that radiate electromagnetic radiation such as cell phones, airplanes, computers etc.

o Is it unsafe to boil a cup of water in a microwave oven?
This is true and one of the most dangerous thing to do in microwave oven. When you heat water in microwave oven for too long, the microwaves prevent the formation of bubbles which would otherwise have cooled the water down. As a result, the water becomes too hot and when you put something in it, the heat releases dangerously and this may erupt the boiling water out of the cup.

o Can cooking food in microwave ovens make it unsafe?
When you cook food, irrespective of the method, the cooking always changes the food chemistry. It is a known fact that cooking reduces the amount of nutrients in food. However, studies have suggested that there is no proof that microwaving of food changes the food quality in a harmful manner. In contrast, some people have argued that since microwave cooking is faster than the traditional way of cooking, it may actually retain more nutrients.

Food is the elixir of life. So, care should be taken to have hygienic and nontoxic food. Microwave oven stands there for that purpose. It is a kitchen appliance that cooks food by using microwaves in the electromagnetic spectrum. For shorter wave lengths, there will be more energy in microwaves. This energy in microwaves is ample to vibrate the organic molecules in the food and thereby produces heat. Microwaves judder approximately 2.5 billion times per second. Microwave ovens heat food without affecting the container. Containers made of plastic, paper, glass, ceramic can be used for cooking in microwave ovens, as they are impervious to microwaves as well as they allow the waves to pierce them.

These waves are reflected by metal facades. Because of this, the microwave oven has metal coating inside so as to reflect the microwaves produced by magnetron to pass through the food again and again. Ceramic cook wares are largely preferable. The cookware should be kept open.

Microwave oven requires high voltage transformers for supplying current to magnetron which in turn ignites electrons to produce microwaves of desired frequency, inside the oven. There will be a micro-controller and a cooking chamber to facilitate cooking.

Inspite of having microwave ovens in your kitchens,a good number of you may be unaware of how it works.

It commences its work by passing microwave radiations, which are non-ionizable, through the food item, at a frequency of 2.45 GHz. These microwaves are generated by magnetron, the tube of electrons which is to be had inside the oven. By means of dielectric heating, water, sugar, fats etc. in the food absorb energy from the radiation. Since the microwave ovens use non-ionizable radiations, there won’t be any risk of having cancer. Heat is said to be the movement of molecules. Many polarized molecules in the food like water have both positive and negative charges in them.

Based on the alternating electric field produced by the microwaves, the charges tend to align themselves which leads to the movement of molecules whose collision leads to heat. This heat cooks the food. As the microwave energy is immediately converted into heat, there is no harm of radioactivity in the cooked food. Food with more water content is cooked against the clock in comparison with those with less water. This technique causes the outer layers to get heated up first and foremost and from there, the heat is conducted to the inner layers.

The intensity of penetration of microwaves depends on the frequency and food composition. The lower the frequency, the greater is the rate of penetration.

In conservative ovens, the cooked food and the cookware will be at the same temperature which is not seen in case of microwave ovens. Here the cookware will be cooler than the food, because, the microwaves penetrate the cookware and heat the food first and from that one, the cookware is heated indirectly. The microwave oven expends less energy than conventional ovens, as it cooks faster only the food but not the cookware. These ovens don’t trim down the nutrition value of the food as it cooks more rapidly.

As it depends on the amount of water used, steaming vegetables in microwave oven results in retaining 77% of nutrients, when compared with heating in stove.

Microwave ovens are used in restaurants, homes, industries, as they are both energy efficient and time efficient, supporting good quality. These microwave ovens are normally used for preparing food and reheating old stuffs in few minutes. Microwave ovens have some limitations, as they are not suitable for flavor-enhancing reactions, browning etc. Sometimes, bacterial destruction is not possible if it doesn’t reach the appropriate temperature. This may lead to illness. Apart from these limitations, the role played by microwave oven in day-to-day life is highly appreciable.
