How to Get Rid of Lipase in Breast Milk?

Does freeze drying breast milk get rid of the lipase taste? Freeze drying breast milk is a popular method for long-term storage and preservation. One common concern among breastfeeding mothers is the presence of the lipase enzyme, which can cause a soapy or metallic taste in the milk.

In this article, we will explore whether freeze drying effectively gets rid of or inhibits the lipase enzyme and whether it improves the quality and taste of breast milk.

Key Takeaways

• Freeze drying breast milk is a method for long-term storage.
• Lipase enzyme can cause an unpleasant taste in frozen stored breast milk.
• We will explore whether freeze drying removes lipase, or inhibits lipase, and if it improves milk quality.

Understanding Lipase in Breast Milk

Lipase is an enzyme naturally present in breast milk, and it plays a vital role in the digestion process of infants. Its primary function is to break down fats into smaller molecules, known as fatty acids and glycerol, which are more easily absorbed and utilized by the baby’s body. Lipase ensures that the fats present in human milk are in a form that the baby can adequately digest and absorb.

What is Lipase and Its Function?

Lipase is an enzyme produced in the mammary glands of breastfeeding mothers. It is secreted into freshly pumped milk to aid in the digestion of fats. When the baby consumes breast milk, lipase interacts with the fats in the milk, breaking them down into smaller components. This process, known as lipolysis, allows the baby’s digestive system to absorb the nutrients from the fats effectively.

Without lipase, the fats in breast milk would remain largely undigested, leading to potential digestive discomfort for the baby. Lipase ensures that breast milk is properly metabolized, promoting optimal nutrient absorption and overall growth and development.

Common Concerns with High Lipase Milk

While lipase is an essential enzyme in breast milk, and some mothers may have what is considered to be high lipase breast milk. This can lead to concerns regarding the taste and smell of stored, refrigerated, or frozen milk. Taste and smell are not factors in freshly expressed milk or while nursing. 

Instead, high lipase milk can develop an unpleasant soapy or metallic taste when stored in the refrigerator or freezer. This can be concerning for breastfeeding mothers as it may affect their baby’s willingness to consume the collected milk. Some babies may refuse to drink this stored milk, resulting in wasted breast milk and potential challenges in exclusively breastfeeding.

Mothers may worry about these sensory changes in their stored breast milk, especially if they plan to use expressed milk for bottle feeding or when they are unable to breastfeed directly. However, it’s important to note that high lipase milk is still safe for the baby to consume and does not pose any health risks. The smell or taste changes do not indicate spoilage or decreased nutritional value.

Understanding lipase activity and its potential impact on the quality of breast milk can help mothers make informed decisions about storage methods and address any concerns they may have about the taste and odor of their expressed milk.

Freeze Drying Deactivates Lipase Enzymes: Myth or Fact?

The impact of freeze drying on lipase activity in breast milk has been a topic of interest among breastfeeding mothers. Studies have shown that freeze drying can effectively deactivate the forms of lipase enzyme when proper levels of water activity are achieved, and through the natural sublimation of water, reduces the soapy/metallic and unpleasant taste associated with high lipase milk.

The process of freeze drying involves removing water from the milk, which in turn strips lipase of the vital cellular water it needs to function and prevents further degradation of the milk’s quality. Lipase is still present in the milk and, once rehydrated, will begin to function once again.

To better understand the impact of freeze drying on lipase activity, let’s compare it to other common preservation methods and analyze the results.

Comparing Freeze Drying to Other Preservation Methods

When it comes to preserving breast milk, there are various methods available. This section will compare freeze drying to two common preservation methods: traditional freezing and heat pasteurization. Understanding the differences and benefits of each method is crucial for breastfeeding mothers in making an informed decision about how to preserve their breast milk.

Traditional Freezing vs. Freeze Drying

Traditional freezing, as the name suggests, involves storing breast milk at extremely low temperatures to slow down bacterial growth and preserve the milk’s freshness. While traditional freezing is a widely used method, it has some drawbacks. One of the main challenges is the formation of ice crystals (freezer burn) during freezing and thawing, which can potentially affect the taste, texture, and overall quality of the previously frozen milk.

Freeze drying, on the other hand, is a sublimation process that involves removing water from the breast milk while retaining its nutritional properties. This method offers several advantages over traditional freezing. Firstly, freeze dried breast milk has a significantly longer use by date and is shelf stable compared to frozen breast milk. Additionally, freeze drying avoids the formation of ice crystals, resulting in milk that maintains its original taste, texture, and nutritional integrity when rehydrated.

While freeze drying may require specific equipment and initial investment costs, the benefits it offers, such as improved quality and longer shelf life, make it an attractive option for many breastfeeding mothers.

Heat Pasteurization and Lipase Inactivation

Heat pasteurization (scalding) is a commonly used method to deactivate lipase in breast milk. By exposing the milk to heat at a specific temperature for a set period, the lipase enzyme is denatured, reducing the likelihood of the milk developing a soapy or metallic taste during storage.

Compared to freeze drying, heat pasteurization is a simpler and less time-consuming process. However, it is important to note that heat pasteurization can affect the nutritional content, taste, and quality of breast milk to some extent. High temperatures without accurate temperature control can lead to the loss of certain enzymes and nutrients, potentially impacting the overall nutritional value of the milk. Overheating can also lead to milk curdling and the burning of lactose sugars.

Additionally, some breastfeeding mothers prefer freeze drying over heat pasteurization due to the longer shelf life and better overall preservation of the milk’s nutritional integrity. However, it is recommended for mothers to consult with healthcare professionals or lactation consultants before deciding on a preservation method, taking into consideration their individual needs and circumstances.

Enhance Your Breastfeeding Journey

The process of freeze drying breast milk can effectively deactivate the lipase enzyme, inhibiting its function, and also results in improved quality and taste of the milk. Once rehydrated, the lipase will react and continue to function as intended. 

Companies like BoobieJuice offer freeze dried breast milk services to stop breast milk lipase breakdown. By removing the moisture from the milk while retaining its nutritional properties, freeze drying offers a long-term storage solution without compromising the essential nutrients. 

Freeze dry your high lipase milk early to maximize the taste and aroma of your high lipase milk. This preservation method has been found to be particularly beneficial for breastfeeding mothers who want to ensure the optimal sensory experience of their milk.
