Can blood be used as a substitute for eggs?

In this brief guide, we will answer the query, “Can blood be used as a substitute for eggs”? and will discuss in what ways egg and blood are similar that can be substituted.

Can blood be used as a substitute for eggs?

Yes, blood can be used as a substitute for eggs.

There is nothing more disgusting than cooking with blood, but the Nordic Food Lab is all about experimenting and breaking boundaries when it comes to food. That’s how they concluded that blood might be used as

Although the notion of utilizing blood as a replacement for eggs intrigues me from a scientific and cultural standpoint, both of which are important to the Even when the complete animal was utilized instead of just a few organs in the past, blood played a significant role in cooking. Its usage as a cooking ingredient has a That impact may be traced throughout Europe, from Scandinavia to France to Poland.

Nordic Food Lab went a step further by testing if blood coagulating qualities might be used in baking in the same way as eggs are.

Most likely you won’t see blood ice cream at any of our ice cream trucks anytime soon, but utilizing blood for food makes more sense than it does now. Swedish researchers estimate that around 70% of blood from piglets ends up in animal feed, pharmaceutical goods, and cosmetic items like cigarette filters.

Composition of blood

Even if the composition of the blood of different mammal species is similar, the volume of blood collected per animalis different.  Pigs, for example, have a blood content of about 3.3 percent of their body weight, resulting in around 2.5 liters of blood.

Blood is a combination of blood cells and serum that is homogeneous. Water (80%) and proteins (17%) such as fibrinogen, albumin, and globulin, as well as glucose, minerals, and hormones, make up the majority of serum (55%).

Approximately 50% of the serum’s total protein content is made up of serum albumin, which is the most abundant and essential in terms of protein composition, it’s comparable to ovalbumin in eggs, which accounts for about 60% of the overall protein amount.

Hemoglobin, an iron-bound protein responsible for the red color of blood cells, is found mostly in red blood cells, although there are also white blood cells and platelets in the serum as well as platelets and thrombocytes. These iron ions undergo chemical processes that are influenced by storage conditions, oxygen availability, and temperature, similar to the color changes that occur in meat. Even though blood is dark purple when vacuum-packed and brilliant red when left out in the sun or foamed up, a heat treatment that causes protein denaturation gives the blood a dark chocolate brown, almost black color.

Properties of blood

Europe’s culinary tradition of using animal blood has a long history, however, it has fallen Because we are interested in (re)valuing those who are hated and forgotten, we had to go a little deeper into the definition of blood as well as its proper handling and Since egg allergy is one of the most common food allergies among children in Europe, we turned to blood for its coagulating characteristics as an egg replacement.

In reality, the protein compositions of eggs and blood are very similar, especially when it comes to albumin, which gives both they’re, for example, one egg white may be substituted with 65g of blood, or 43g of blood can be substituted for one egg yolk (about 33g). Blood-ice cream, ‘chocolate’-blood sponge cake, sourdough-blood pancakes, and blood meringue have all been created using this approach.

Benefits of using blood

As a result of the high bioavailability of heme-iron in blood, it can prevent anemia, which is the most prevalent micronutrient deficiency in the world today It’s no secret that iron may be difficult to eat, but in many cultures, it’s been countered by combining it with strong flavors like herbs and spices. Woodruff and toasted koji were among the newest combinations we explored.

This led to an intriguing conversation on the link between gender, age, and taste.

Blood as an alternative for eggs

Die zunehmende Egg-protein-Allergie, today’s second-most-common food allergy in Europe, affects mostly children but also adults and is one of the strongest arguments for using blood So, in Germany, 8% of youngsters experience an egg response. Around 30-53% of children with food allergies in countries like Spain and France have an allergy to ovalbumin, according to other sources.

When it comes to protein makeup, blood is quite similar to an egg, although, with slightly different sorts of While albumin, the major component of blood protein, is well tolerated, ovalbumin in egg white triggers severe allergic responses in many people. Iron deficiency causes anemia, the world’s most prevalent micronutrient deficit.

Moreover, heme-iron in blood has a 2- to 7-fold bioavailability compared to non-heme iron.
