The world of dairy products can be complex and overwhelming, especially when it comes to understanding the differences between various types of milk. Two terms that often cause confusion are “evaporated milk” and “scalded milk.” While they may seem similar, these two types of milk have distinct differences in terms of their production process, nutritional content, and usage in cooking. In this article, we will delve into the world of evaporated and scalded milk, exploring their unique characteristics and uses.
Understanding Evaporated Milk
Evaporated milk is a type of milk that has been sterilized by heat to remove about 60% of its water content. This process, known as evaporation, involves heating the milk to a high temperature (usually around 145°C) for a short period, followed by rapid cooling. The resulting milk is creamy, rich, and has a longer shelf life than regular milk.
The Production Process of Evaporated Milk
The production of evaporated milk involves several steps:
- Milk Collection and Preparation: Fresh milk is collected from dairy farms and transported to the processing plant. The milk is then pasteurized to kill off any bacteria and extend its shelf life.
- Evaporation: The pasteurized milk is then heated to a high temperature (around 145°C) in a large, shallow pan or evaporator. This process removes about 60% of the water content, resulting in a creamy and rich milk.
- Homogenization: The evaporated milk is then homogenized to ensure that the fat molecules are evenly distributed throughout the milk. This process involves forcing the milk through a small opening under high pressure, breaking down the fat molecules into smaller particles.
- Packaging and Sterilization: The evaporated milk is then packaged in aseptic containers, such as cans or cartons, and sterilized through heat treatment or ultra-high temperature (UHT) processing.
Nutritional Content of Evaporated Milk
Evaporated milk is a good source of protein, calcium, and vitamins D and B12. However, it is also high in calories and fat, especially saturated fat. A 1-cup serving of evaporated milk contains:
- Calories: 170
- Protein: 17 grams
- Fat: 10 grams (7 grams saturated)
- Calcium: 30% of the Daily Value (DV)
- Vitamin D: 25% of the DV
- Vitamin B12: 20% of the DV
Understanding Scalded Milk
Scalded milk, on the other hand, is milk that has been heated to a temperature of around 82°C (180°F) for a short period, usually 5-10 minutes. This process, known as scalding, involves heating the milk to a temperature that is just below boiling point, but not quite hot enough to boil.
The Production Process of Scalded Milk
The production of scalded milk is relatively simple and involves the following steps:
- Milk Collection and Preparation: Fresh milk is collected from dairy farms and transported to the processing plant. The milk is then pasteurized to kill off any bacteria and extend its shelf life.
- Scalding: The pasteurized milk is then heated to a temperature of around 82°C (180°F) for 5-10 minutes. This process denatures the proteins in the milk, making it more suitable for cooking and baking.
- Cooling: The scalded milk is then cooled to a temperature of around 4°C (39°F) to stop the cooking process.
Nutritional Content of Scalded Milk
Scalded milk has a similar nutritional content to regular milk, with a slightly higher calorie and fat content due to the heating process. A 1-cup serving of scalded milk contains:
- Calories: 160
- Protein: 16 grams
- Fat: 9 grams (6 grams saturated)
- Calcium: 30% of the DV
- Vitamin D: 25% of the DV
- Vitamin B12: 20% of the DV
Key Differences Between Evaporated and Scalded Milk
While both evaporated and scalded milk are types of milk that have been heat-treated, there are several key differences between them.

Choosing the Right Type of Milk for Your Recipe
When it comes to choosing the right type of milk for your recipe, there are several factors to consider. Here are some tips to help you make the right choice:
- Consider the texture: If you want a creamy and rich texture, evaporated milk may be the better choice. If you want a smooth and creamy texture, scalded milk may be the better choice.
- Consider the flavor: Evaporated milk has a slightly sweet and nutty flavor, while scalded milk has a more neutral flavor.
- Consider the nutritional content: Evaporated milk is higher in calories and fat than scalded milk, so if you’re watching your diet, scalded milk may be the better choice.
By considering these factors, you can make an informed decision about which type of milk to use in your recipe.
What is evaporated milk, and how is it made?
Evaporated milk is a type of milk that has been sterilized by heat to remove about 60% of its water content, resulting in a creamy and rich texture. The process of making evaporated milk involves heating milk to a high temperature, usually around 145°C (293°F), in a vacuum chamber or under reduced pressure. This causes the water content to evaporate, leaving behind a concentrated milk product with a longer shelf life.
The resulting evaporated milk is then packaged in aseptic containers, such as cans or cartons, and can be stored for several months without refrigeration. The sterilization process also kills off any bacteria that may be present in the milk, making it a popular choice for cooking and baking applications where a long shelf life is desired.
What is scalded milk, and how is it different from evaporated milk?
Scalded milk, on the other hand, is milk that has been heated to a temperature of around 82°C (180°F) to kill off any bacteria that may be present. Unlike evaporated milk, scalded milk is not sterilized to the same extent, and its water content is not significantly reduced. Scalded milk is often used in recipes where a slightly thickened and creamy texture is desired, such as in sauces, soups, and baked goods.
The main difference between scalded milk and evaporated milk is the level of heat treatment and the resulting texture and shelf life. While scalded milk is still a liquid with a relatively short shelf life, evaporated milk is a concentrated product with a much longer shelf life due to its sterilization process.
Can I substitute evaporated milk with scalded milk in recipes?
In some cases, you can substitute evaporated milk with scalded milk in recipes, but it’s not always a 1:1 substitution. Since scalded milk has a higher water content than evaporated milk, you may need to adjust the amount of liquid in the recipe accordingly. Additionally, scalded milk may not provide the same level of creaminess and richness as evaporated milk, so you may need to add additional ingredients to achieve the desired texture.
However, if you’re looking for a substitute for evaporated milk in a pinch, scalded milk can be a decent option. Just be aware of the potential differences in texture and flavor, and adjust the recipe accordingly. It’s also worth noting that scalded milk may not be suitable for recipes where a long shelf life is required, such as in canned goods or shelf-stable products.
What are the nutritional differences between evaporated milk and scalded milk?
Evaporated milk and scalded milk have similar nutritional profiles, with the main difference being the water content. Evaporated milk has a higher calorie and fat content due to its concentrated nature, while scalded milk has a lower calorie and fat content due to its higher water content. However, both types of milk are good sources of protein, calcium, and vitamins D and B12.
It’s worth noting that some brands of evaporated milk may have added ingredients, such as thickeners or stabilizers, which can affect the nutritional content. Scalded milk, on the other hand, is often made from whole milk and may contain more natural nutrients and less added ingredients. Always check the label to ensure you’re getting the nutritional content you’re looking for.
Can I make evaporated milk at home?
Yes, you can make evaporated milk at home by heating milk to a high temperature and reducing its water content. However, it’s not a straightforward process, and it requires some specialized equipment, such as a vacuum chamber or a double boiler. You’ll also need to be careful to avoid scorching the milk or creating a grainy texture.
One way to make evaporated milk at home is to heat milk to 145°C (293°F) in a double boiler, stirring constantly, until it reaches the desired consistency. You can also use a slow cooker or Instant Pot to make evaporated milk, but be sure to follow a tested recipe and take necessary safety precautions. Keep in mind that homemade evaporated milk may not have the same shelf life as store-bought evaporated milk.
What are some common uses for evaporated milk and scalded milk?
Evaporated milk is often used in recipes where a creamy and rich texture is desired, such as in soups, sauces, and baked goods. It’s also a popular choice for making mac and cheese, creamy pasta dishes, and desserts like crème brûlée. Scalded milk, on the other hand, is often used in recipes where a slightly thickened and creamy texture is desired, such as in sauces, soups, and baked goods.
Both evaporated milk and scalded milk can be used as a substitute for heavy cream or half-and-half in many recipes, making them a popular choice for those looking to reduce calories or fat content. They can also be used as a base for homemade ice cream, yogurt, or cheese recipes.
How do I store evaporated milk and scalded milk?
Evaporated milk can be stored in a cool, dry place for several months without refrigeration, due to its sterilization process. However, once opened, it’s best to store it in the refrigerator and use it within a few days. Scalded milk, on the other hand, should be stored in the refrigerator and used within a day or two, as it can spoil quickly.
When storing evaporated milk, make sure to check the expiration date and follow proper food safety guidelines. If you’re storing scalded milk, be sure to label it with the date it was made and use it promptly to avoid spoilage. Always check the milk for any signs of spoilage before consuming it, such as an off smell or slimy texture.
