What temperatures do proteins in breast milk begin to break down?

What temperatures do proteins in breast milk begin to break down? Background on Human Breast Milk Proteins Human breast milk contains a diverse array of proteins, including whey proteins (e.g., α-lactalbumin, lactoferrin, lysozyme) and immunoglobulins (e.g., secretory IgA), which are crucial for infant nutrition, immunity, and gut development. These proteins are sensitive to heat, and their denaturation can lead to loss of function, such as reduced antimicrobial activity or altered digestibility. The denaturation temperature varies by protein, influenced by factors like pH, ionic strength, and heating duration, which are often studied in the context of pasteurization for donor milk banking Methodology and Data Sources The analysis draws from multiple scientific studies, with a focus on those directly addressing human breast milk, such as pasteurization effects. Key sources include studies on immunological protein retention and reviews of milk protein denaturation, supplemented by data on cow’s milk proteins where human-specific data are scarce, given similarities (e.g., α-lactalbumin). Temperatures are reported in Celsius, as is standard in scientific literature, with the understanding that these are based on typical experimental conditions like 30-minute exposures. They main protein components of human breast milk are: Whey Proteins (about 60-70%): Lactoferrin: Binds iron and has antimicrobial properties. Alpha-lactalbumin: Aids in lactose synthesis and provides essential amino acids. Lysozyme: Offers antibacterial protection. Immunoglobulins (mainly IgA): Provides immune protection against pathogens. Serum albumin: Plays a role in nutrient transport. Casein Proteins (about 30-40%): Beta-casein: The predominant form, providing essential amino acids and aiding in calcium absorption. Kappa-casein: Helps stabilize casein micelles, important for digestion. These proteins support infant growth, immune protection, and the development of the digestive system. Casein proteins are relatively heat-stable compared to other milk proteins like whey. They don't denature in the same way because they exist as micelles, which are more resistant to heat. However, significant changes can occur at temperatures above 100°C (212°F), especially under prolonged heating or in acidic conditions. Casein coagulation, such as in cheese-making, often relies more on pH changes than heat alone. Temperatures for Onset of Mild Loss of Function of Protein Components Mild loss of function occurs when proteins begin to denature, typically at the lower end of the temperature range where structural changes or reduced bioactivity are detectable. Below, I list the temperatures at which each protein starts to lose function, based on human milk studies or bovine milk data where human-specific data are limited. Temperatures are converted from °C to °F using °F = (°C × 9/5) + 32. I focus on the earliest reported denaturation temperatures, often from studies of pasteurization or thermal processing. 1. α-Lactalbumin : • Onset Temperature : ~64°C (147.2°F) • Details : Denaturation is reversible at this stage; mild loss of lactose synthesis activity begins. • Source : Food Chemistry (2019). 2. Lactoferrin : • Onset Temperature : ~75°C (167°F) • Details : Minimal loss of antimicrobial activity at 75°C; stable below this. • Source : Lönnerdal, B. (2013). 3. Lysozyme : • Onset Temperature : ~80°C (176°F) • Details : Slight reduction in antibacterial activity at 80°C for short durations (e.g., 15–30 seconds). • Source : Lönnerdal, B. (2013). 4. Immunoglobulins (Secretory IgA) : • Onset Temperature : ~56°C (132.8°F) • Details : Earliest loss of immune-protective function at 56–60°C for 30 minutes. • Source : Journal of Dairy Science (1955). 5. β-Casein : • Onset Temperature : ~100°C (212°F) • Details : Caseins are highly heat-stable; mild denaturation only at boiling point or above, with minimal functional loss below 100°C. • Source : Lönnerdal, B. (2003). 6. Bile Salt-Stimulated Lipase (BSSL) : • Onset Temperature : ~60°C (140°F) • Details : Initial inactivation of lipid digestion activity at 60°C for 30 minutes. • Source : Lönnerdal, B. (2003). 7. Amylase : • Onset Temperature : ~63°C (145.4°F) • Details : Slight reduction in carbohydrate digestion activity at 63°C for 30 minutes. • Source : Lönnerdal, B. (2003). Detailed Findings on Denaturation Temperatures Below, we detail the temperatures at which major proteins in human breast milk begin to lose function, based on available research: • Immunoglobulins (e.g., Secretory IgA) : • Research indicates that immunoglobulins are among the least heat-resistant proteins, with studies showing retention of at least 90% at 57°C for 30 minutes, but significant loss (72.3% retention) at 62.5°C for 30 minutes ( Retention of the Immunological Proteins of Pasteurized Human Milk in Relation to Pasteurizer Design and Practice ). This suggests the onset of function loss begins around 60°C, with rapid decline at higher temperatures. • The sensitivity is likely due to the complex structure of immunoglobulins, which can unfold and aggregate under heat, reducing their immune-protective capabilities. • Lactoferrin : • Lactoferrin, an iron-binding protein with antimicrobial properties, shows high retention (at least 90%) at 57°C for 30 minutes, but retention drops to 21.8% at 62.5°C for 30 minutes, indicating significant denaturation above 57°C ( Retention of the Immunological Proteins of Pasteurized Human Milk in Relation to Pasteurizer Design and Practice ). This suggests it begins losing function above 57°C, with notable impact at 62.5°C. • Reviews like “Lactoferrin: Structure, function, denaturation and digestion” ( PubMed ) note its heat sensitivity, but specific human milk data are limited, reinforcing the reliance on pasteurization studies. • Lysozyme : • Lysozyme, an enzyme with antibacterial activity, also shows at least 90% retention at 57°C for 30 minutes, but retention falls to 39.4% at 62.5°C for 30 minutes, suggesting function loss begins above 57°C ( Retention of the Immunological Proteins of Pasteurized Human Milk in Relation to Pasteurizer Design and Practice ). Studies like “Thermal denaturation of recombinant human lysozyme from rice: Effect of pH and comparison with human milk lysozyme” ( ResearchGate ) indicate similar thermostability, with denaturation starting at higher temperatures, but human milk data confirm the 57°C threshold. • α-Lactalbumin : • α-Lactalbumin, a major whey protein involved in lactose synthesis, is relatively heat-stable. While direct human milk studies are limited, cow’s milk studies like “The denaturation of α-lactalbumin and β-lactoglobulin in heated milk” ( Journal of Dairy Research ) suggest denaturation begins around 64°C, with significant loss at higher temperatures. Given its similarity in human and bovine milk, it seems likely human α-lactalbumin starts losing function around 64°C. Implications and Limitations The findings are crucial for practices like donor milk banking, where Holder pasteurization (62.5°C for 30 minutes) is standard but can significantly reduce protein bioactivity. For home use, warming milk above 57°C could reduce nutritional benefits, especially for preterm infants reliant on these proteins for immunity. However, the data are primarily from pasteurization studies with 30-minute exposures, and shorter heating times (e.g., in bottle warming) might delay onset. Additionally, human milk studies are less common than bovine milk studies, so some inferences (e.g., for α-lactalbumin) are based on cow’s milk data, which may not perfectly align due to compositional differences. Conclusion In summary, proteins in human breast milk begin to lose function at temperatures above 57°C, with immunoglobulins, lactoferrin, and lysozyme showing sensitivity above this threshold, and α-lactalbumin being more resistant, starting around 64°C. These temperatures are critical for maintaining milk’s nutritional and immunological properties, particularly in clinical or storage contexts. Notes • Data Limitations : Exact onset temperatures for human milk proteins are often extrapolated from bovine milk or formula studies (e.g., Food Chemistry , 2019) due to limited human milk experiments. Human proteins may be slightly more heat-resistant. • Mild Loss : This refers to the earliest detectable denaturation (e.g., partial unfolding or reduced bioactivity), often reversible for some proteins (e.g., α-lactalbumin). Significant loss occurs at higher temperatures, as noted previously. • Time Dependency : Denaturation at these temperatures assumes typical processing times (e.g., 15–30 seconds for high-temperature short-time, 30 minutes for Holder pasteurization). Shorter exposures may delay onset.

How long can my breast milk be frozen in bags?

We Freeze Dry all of your breast milk shipped to us as long as it is received in a frozen state. CDC Recommends fresh human breast milk is best up to 6 months in a freezer and acceptable consumption up to 12 months. Many breast milk banks discard unused frozen milk after 3 months. Keep your stash safe by Freeze Drying!

We have mothers process milk upwards of 18+ months. It is up to you and your goals. There are many uses for freeze dried powdered milk from bottles, fortifying foods, bath bombs, milk bath powder, lotions and more!

How many ounces per bag?

We will accept most brands of lacations bags in any volume size. We recommend not filling past the bags recommended volume line to ensure bags do not split during freezing.

I have high lipase enzyme milk, can freeze drying help?

Freeze drying your breastmilk can help! The less time breast milk is stored in a freezer, the less time lipase has to breakdown fats. If you are prone to higher lipase, freeze drying can be an affective solution to optimally store your breast milk. Freeze drying removes the water and deactivates the lipase enzyme. This stops the enzyme from breaking down fats and helps retain the overall nutrition while in storage. Freeze drying can also improve the taste and aroma of milk already affected by lipase. The sooner you can freeze dry the breastmilk, the better overall taste, aroma and nutrition for baby. Lock in the nutrition and taste of your babies superfood by freeze drying your stash today while saving space in the freezer! Check out this article and links Freeze Drying vs Freezer

I have information written on my bags, is that saved?

Yes! each bag is individually tracked and documented. Your expression date and notations will be recorded and printed on your rehydration instructions. If you do not have expression dates or notes, no worries, the specific rehydration information will still be present.

My breast milk is frozen in cubes?

We can accept milk cubes. We do require you to place them into common pre-sterilized breast milk bags in the desired serving sizes.

My breast milk is in NICU bottles?

We can accept pre-sterilized NICU plastic bottles that are sealed. We currently are not processing glass bottles. Please contact us as bottles take up additional space and our shipping kits are rated for standard breast milk pouches. Typically NICU bottles require 1.5x-2x the space to ship based on fill. Additional processing fee may apply. Please call / text 602-456-1492 or email ilove@boobiejuice.com to discuss your processing needs.

What age breast milk do you take or should I send?

That’s totally up to you. We have some Moms send their most recent stash to preserve the most nutrients as possible. The sooner breast milk is frozen and then freeze dried, the greater amount of nutrition is preserved. While other Moms send us their oldest milk to provide the extended longevity, prevent further degradation and to make room for more of their stash. If you follow the CDC’s guidelines on expressed breastmilk storage, breast milk is acceptable for 12 months when stored in a freezer.

What brands of breast milk storage bags do you accept?

We accept all readily available pre-sterilized lactation bags designed specifically for infant food storage. All other packaging will not be accepted. Should you have any questions? Please call / text 602-456-1492 or email ilove@boobiejuice.com

How do I know how much milk I have?

For the most accurate measurement, we recommend you use a bathroom scale or kitchen scale and weigh your milk.

With a bathroom scale:
Place a holding container down. Note the weight of the container.
Place all your milk in the container and note the total weight
Subtract the container weight.
Now you have you milk + pouch weight.

You may also count the pouches and subtract out the pouch weight if you wish. Common pouches weigh between .14oz to .2oz. You may weigh you pouch for an exact weight.

Shipping kits provide a range they hold. You will need to have an idea of the total weight of milk prior to shipping. All milk pouches will be weighed and counted on receipt and orders will be pro-rated based on the service selected at checkout.

Local drops offs are weighed in and counted at your drop off time so you have your drop off weight.

How do I update my orders shipping address?

Please email us ilove@boobiejuice.com

How many oz are in each freeze dried pouch?

BoobieJuice on the Go Pouches are created using our contactless, bag for bag process. We freeze dry your original pouches into a new freeze dried pouch. All of your original expression dates, food allergens, times, and even daily affirmations are all transferred on to your new freeze dried pouch. This process virtually illuminates any cross contact exposure. Your milk is not hopped, blended or mixed. Your colostrum pouches are preserved and freshly expressed frozen milk is not mixed with older oxidized and lipase affected milk.You have complete control of your milk, just like your frozen pouches. Your breast milk varies between 80–90% water depending on each unique expression. Nutrition density of breast milk varies from the stage of which you are producing, morning or night expression, diet and personal hydration levels. Your milk is unique to you and your baby’s needs. Our freeze dried pouches are resealable if you only use a portion and you can also rehydrate an entire bag and refrigerate the un-used portion for up to 24 hours. Should you have smaller 1-2oz portions dated in range, we can facilitate merging two small pouches into 1 new freeze dried pouch. Your milk will transfer from pouch to pouch and retain the dates and notes of each pouch along with the total water and total powder amounts on the new pouch.

Using your Freeze Dried Breast Milk

Can I carry on my pouches when flying?

Yes, your pouches contain around 15g of breast milk powder and are clearly marked. No need to refrigerate or keep cool.

How do I reconstitute my powder?

On the back of each BoobieJuice package is the exact water needed to reconstitute your milk to its original nutrition ratios.

Warm clean purified water in a separate container
Measure out the required water amount per instruction on the back of the pouch.
Add BoobieJuice powder to the bottle.
Add the required amount of water to the bottle and swirl.
If clumps remain after a minute of swirling, place the bottle into a warm water bath or under warm running water. Swirl again.
Depending on the fat constitution, it may take up to 5 minutes for the warm water and powder to dissolve. Be Patient.

How long do opened pouches last?

We recommend pressing out all of the air from the unused portion and resealing the portion. Both On the GO and At Home Pouches if properly resealed can be stored up to 30 days after opening. Please keep the pouch at room temperature and out of direct sunlight.

How much powder do I use to fortify foods?

On average there is 20kcal per oz of breast milk. This then equates to an average of .1oz of freeze dried powder. Add as little or as much to fortify foods based on your babies nutritional needs. Keep in mind, each powder pouch is equal to one of your original bottles. Your powder is loaded with beneficial proteins, pre/probiotics, fats, sugars and immune response agents. A power packed nutrition boost for the kcal intake. Your breast milk’s nutrition varies each day due to the time of day expressed and your dietary intake. The nutrition you consume is actively passed through into milk production. Your freeze dried pouches will exhibit the same variations. For specific nutritional density, we offer breast milk nutritional testing through Lactation Lab. Should you be interested in specific nutritional densities, BoobieJuice can help facilitate powder testing or we can send you a testing kit to analyze your fresh milk with recommendation from Lactation Labs!

How much water do I add to my pouches?

Each individual pouch has the specific rehydration requirements for you. A typical 6oz bag will have 0.6 oz of powdered breast milk and will require 5.4fl oz of water. Typically you will see a 90% reduction in a breast milk bag when it is Freeze Dried. See the individual pouch details for specific rehydration needs.

Storage recommendations

Powder Pouches

Store pouches in a cool dry place indoors and out of direct sunlight.
Once a pouch is open, remove as much air as possible and seal the bag closed. Properly resealed bags can last up to 30 days after opening. Keep the pouch at room temperature. Do not place inside a refrigerator.

Rehydrated Breast Milk

Use within 2 hours of rehydration and 1 hour after beginning to feed. Saliva can cause bacteria growth.
If unused within 2 hours, place milk in the refrigerator and use within 24 hours.
Do not freeze re-hydrated milk.
Discard any unused milk after 24 hours.
Sanitize bottles between use.

What kind of water do I use?

We recommend using clean filtered water. Reverse osmosis water or vapor distilled water are great options and have very low to zero total dissolved solids. Total dissolved solids include all organic and inorganic dissolved contaminants including metals, salts, minerals, and ions.

Filtered retail packaged bottled waters are convenient options. Remember, the water you use may have varying levels of trace elements TDS. If you are looking to remove any excess mineral additives distilled water is your best option.

We would recommend staying away from tap water as there are higher total dissolved solids including salts, calcium, chlorine, fluorides, and heavy metals. There are many choices you can make based on your lifestyle and water requirements. Choose what is appropriate for you and your baby.
