Can I add milk to my spaghetti sauce?

Yes, you can add milk to your spaghetti sauce. Milk can improve the nutritional profile of the spaghetti sauce, by adding proteins, calcium and vitamins of the B-complex (4).

Milk can reduce the acidity of the spaghetti tomato sauce and become more friendly to individuals suffering from acid reflux disease (1,2). On the other hand, milk will change the flavor of the spaghetti sauce and make unsuitable to vegan consumers (5).

What are the benefits of adding milk to your spaghetti sauce?

The benefits of adding milk to your spaghetti sauce are:

Milk has a buffering effect. That means, upon the addition of milk to a solution, the concentration of free ions in this solution is reduced. Milk proteins contain amino acids, which are able to bind to OH and H+ ions.

As a consequence, a solution that contains milk proteins is less affected by the presence of acidic or alkaline components. The acidity of the tomato spaghetti sauce can be reduced by the addition of milk or other dairy products (1).

Tomato sauce contains a high amount of organic acids, which characterize it as being an acidic product and not suitable for the consumption by individuals suffering from gastroesophageal reflux disease (2). Adding milk to the tomato sauce can reduce its acidity and favor these individuals.

Milk also contains many nutrients, including high valuable amino acids with bioactive properties that favor growth and the immune system, minerals, such as calcium and magnesium, which are important to the bone formation and health, and vitamins, including vitamin A, B1, B2, D and K (4).

What are the drawbacks of adding milk to your spaghetti sauce?

The drawbacks of adding milk to your spaghetti sauce are:

As mentioned previously in this article, milk has a buffering effect and can trap ions from the solution. This can reduce the flavor of the tomato spaghetti sauce. The flavor of tomato and of tomato sauce is a result of the components in the tomato, including sugars, volatiles and acids (3).

About 15% of the dry matter of the tomato is composed of organic acid, including citric, glutamic and malic acid, which characterize the favor of tomato sauce. Milk will definitively mask this flavor.

Another drawback is that milk is not consumed by vegans. The addition of milk to spaghetti sauce will hinder vegans from eating the sauce (5).
