1. Understanding Food Processing and Eggs

Food processing encompasses a wide range of techniques, from simple washing and packaging to complex industrial modifications. Where do eggs fall on this spectrum? Eggs, in their natural state, are considered minimally processed. However, depending on how they are treated and prepared, they can also be subject to more extensive processing.

1.1 Defining Processed Food

Processed foods are any foods that have been altered from their natural state for safety, convenience, or preservation. This can include washing, cutting, heating, pasteurizing, canning, freezing, drying, mixing, packaging, or adding ingredients like preservatives, flavors, or nutrients. The extent of processing varies greatly, resulting in a wide range of products, from minimally processed whole foods to ultra-processed items.

Minimally Processed Foods: These foods are closest to their natural state and undergo minimal alterations, such as washing, packaging, or simple preservation techniques.
Processed Foods: These foods have undergone some degree of alteration, like cooking, canning, or adding preservatives, but still retain much of their original nutritional value.
Ultra-Processed Foods: These foods undergo extensive industrial processing, often containing many additives, artificial ingredients, and high levels of sugar, salt, and unhealthy fats.

1.2. Where Eggs Fit in: Minimally Processed to Highly Processed

In their simplest form, fresh eggs are considered minimally processed. They are collected, washed, and packaged for sale, with little to no alteration to their natural state. However, eggs can also be subject to more intensive processing methods:

Pasteurized Eggs: These eggs are heated to a specific temperature to kill bacteria like Salmonella, extending their shelf life and improving safety.
Dried Eggs: Eggs can be dehydrated into a powder form for use in baking and other food products.
Liquid Eggs: Egg whites, yolks, or whole eggs can be pasteurized and sold in liquid form, often with added preservatives.
Egg Products: Eggs are used as ingredients in a wide variety of processed foods, such as baked goods, sauces, and prepared meals.

The processing level of eggs depends on the specific product and how it is treated. Minimally processed eggs retain most of their natural nutritional value, while heavily processed egg products may contain added ingredients and undergo significant alterations.
