What is aeration in eggs

In the simplest terms, the purpose of a wine aerator is to force wine to interact with air to accelerate oxidation and evaporation. It does this by sending the wine through a funnel of pressurized oxygen. What is Aeration? Aeration involves perforating the soil with small holes to allow air, water and nutrients to penetrate the grass roots. This helps the roots grow deeply and produce a stronger, more vigorous lawn.

The main reason for aerating is to alleviate soil compaction. Immediately after aeration, your lawn is ripe for overseeding and fertilizing. The holes provide excellent soil exposure for seeds and deliver fertilizer directly to the roots of your grass. Within 48 hours after you aerate you should over seed, fertilize, and water your lawn. The seed, fertilizer, and water will have the best chance to get down into the holes made by the aerator if applied soon after aeration.

You want to aerate the lawn when your grass is in its peak growing period so it can recover quickly—think early spring or fall for cool-season grasses, and late spring through early summer for warm-season grasses.

If you have high-traffic areas or heavy clay soil, you will want to aerate every year. Aeration is simply adding air to a substance. For example beating egg whites creates meringues as air is mixed into the protein contained in the egg whites, creating a foam. Whip egg whites slightly to a foam and then add the sugar in a steady stream. Whip at high speed until the eggs are almost completely whipped and then slow it down for maximum aeration, and finer, more even air bubbles.

Aeration is only successful if the air remains in the batter until it is baked. The steam water vapour causes the pastry to rise. The same process can be applied when you make batters, as well as choux pastry for profiteroles etc. The water in these mixtures turns to steam when the food is cooked in a very hot oven.

Nowhere perhaps is the power of egg white more readily evident than in a meringue. Increasing the acidity of egg whites helps stabilize the foam by loosening the protein structure, keeping the foam elastic and stable enough to entrap air cells, and allowing them to expand when heated, resulting in better volume.

In certain applications whole eggs and egg yolks also increase the volume of foods through the process of aeration, including some baked goods and dairy desserts such as ice cream and custard.

The lecithin in egg yolks is an excellent emulsifier. With the water-loving end of the lecithin molecule buried in the water molecules and the water-hating end buried in the oil molecules, lecithin forms a thin film around tiny drops of oil enabling them to remain suspended in a water-based liquid.

Their ability to hold up to four times their weight in moisture makes eggs a good thickener for sauces, custards and curds.

The proteins in eggs coagulate or set at different temperatures. This results in thickening but it means that eggs must be cooked gently and heated carefully or they will scramble rather than thicken a sauce or other mixture. Lime Pudding Cake with Berries. Aerators are various mechanical devices used for aeration, or mixing air with another substance, such as soil or water. These devices are used to add oxygen to the water. Aerator may also refer to: Floating surface aerators , used in aerated lagoons.

Lung aeration. The effect of pre-oxygenation and hyperoxygenation during total intravenous anaesthesia. The aeration of lung regions identified by computed tomography scans was divided into five categories: over- aeration , normal aeration , reduced aeration , poor aeration , and atelectasis formation. Worms and insects are responsible for soil aeration. The more easily water flows through the soil , the easier it is for your garden plant roots to have access rain water and nutrients the worms have left behind.

Aerating is when air is mixed through or dissolved in a liquid of substance. There are five types of aeration , mechanical,chemical, biological, physical and a combination of more then one.

The powder gets trapped in small air cells created while mixing and then rises when heated. What does OF mean? Aeration is the process of bringing water and air into close contact in order to remove dissolved gases, such as carbon dioxide, and to oxidize dissolved metals such as iron. It can also be used to remove volatile organic chemicals VOC in the water. Some lawns need aerating every year, although most can go two to three years before needing aerating -- which is good, if you don't like the look of brown plugs on your lawn.

You don't have to rake the plugs left by aerating , but doing so gets nutrients back into the soil faster. What does aeration mean in food?
