Cooking With Organic Chemistry!


Chef all around the world has been working their ways through the combination of chemistry of food from every different kind of ingredients to produce one of the best recipe. Every single combination is important as the flavour of food changes as the time of cooking, amount of ingredients and other aspect will be counted in cooking. Chemistry reaction has taken place even before you start to cook. The combination of recipe from the preparation of food has caused reaction to occur from the very beginning. This combination of chemistry reaction caused a vital difference from the way it taste, smell, and looks. Cooking oil has been widely use in cooking and as a component of daily food consumption where it used for frying, baking and other types of cooking. It is also used in food preparation and flavoring that doesn't involve heat. Cooking oil is normally in a liquid state in room temperature but some oil are solid state in room temperature and it belong to a group called lipids that does not dissolve in water.  Cooking oil can be extracted from plant and animal.

There are many different type of cooking oil available and each of these cooking oil have different saturation of fats and other factors. Healthy cooking oils play an important part in our healthy eating plan. Some oils are high in saturated and trans fat which can lead to high cholesterol, heart problem and obesity. Good oil contain monosaturated fats and polyunsaturated fats. These fats are good for lowering cholesterol and preventing health problems. Vegetable oils come from many plants. Examples of vegetable oils are lavender, olive, palm, rapeseed and sunflower. The oil contain a lot of energy and are used as food or other uses such as making fuel. Vegetable oils used in cooking because it has a higher boiling point than water which boils at 100°C. The cooked food usually has more energy because some of the oil remains on the food after cooking. Eating healthy vegetable oil is very important as some vegetable oils are better for health than others. Oils containing many unsaturated fats are more healthy than oils with a large proportion of saturated fats. Unsaturated means that the molecule contains one or more double bonds between carbon atoms. Saturated means that the molecule is bonded with single bond with higher hydrogen molecules. In example, palm oil is more saturated than sunflower oil and therefore it's more recommended to consume sunflower oil than palm oil as it is more healthy and less risk on health problems. Vegetable oils is sustainable as fuels for diesel engine depends on their physical, chemical and combustion characteristics as well as the type of engine used and operation conditions. They are biodegradable, non-toxic and have a potential to significantly reduce pollution.
