Holder Pasteurization Holds Up Well Against Most Germs

Holder Pasteurization Holds Up Well Against Most Germs

There is nothing particularly surprising or complicated about the most common method of making stored milk safer than it would otherwise be. Holder Pasteurization, or HoP, aims to rid milk of potentially harmful germs by heating it to 62.5°C (145°F) for half an hour, and then cooling it back down to room temperature. This method is used by all of the Human Milk Banking Association of North America (HMBANA) milk banks, and differs from the high-temperature, short-time (HTST) pasteurization used in the dairy industry. But these days HoP has some newfangled competitors—potential alternatives to the tried and tested method—suggesting that the time is ripe for a full evaluation of HoP’s performance. This article is the first in a series of five on the topic. Starting at the beginning of this in-depth look, how good is HoP at its core mission: keeping pathogens at bay that could, in theory, find their way into milk and make it their home? Read More...

Milk for Ill and Pre-Term Infants

Milk for Ill and Pre-Term Infants

Unadulterated, fresh, and straight from the breast, experts agree that human milk is the best option for healthy infants. Not only does it provide the macronutrients essential to fuel and build young bodies, it actively stops infants from getting sick by dosing them with immunoglobulins and sugars that are indigestible by humans. A recent review offers a summary aimed at clinicians about how human milk may be modified to cater for the particular needs of pre-term and sick infants. Read More...

Milk’s Bioactive Ingredients Help Wounds Heal Faster

Milk’s Bioactive Ingredients Help Wounds Heal Faster

They say time heals all wounds. But can milk help those wounds heal faster? Noting milk's ability to stimulate and support the development of an infant's immune system, researchers posed the simple, but elegant, hypothesis that milk could accelerate the healing process by enhancing the body's immune response.

A Human Milk Oligosaccharide Protects Against Intestinal Infection and Inflammation

A Human Milk Oligosaccharide Protects Against Intestinal Infection and Inflammation

Sugars found in human milk, called human milk oligosaccharides (HMOs), have various protective effects against intestinal infections. A new study finds that the HMO 2'-fucosyllactose (2'-FL) protects against infection and inflammation caused by the pathogen Campylobacter jejuni. Read More...

Infection-Fighting Formula

Infection-Fighting Formula

There is a plethora of ways in which the composition of infant formula differs from that of breast milk. For one, the latter has a far greater diversity of ingredients, which are still not exhaustively known. But there are also plenty of known constituents of breast milk that are absent from infant formula. One team of researchers is dedicated to figuring out the implications of adding one kind of missing ingredient in particular—milk fat globule membrane (MFGM)—on infants’ health and development. Recently, this group identified some benefits to infants’ abilities to cope with infections when the infant formula they consume contains this supplement [1]. Read More...

The Regenerating Powers of Human Milk Molecules

The Regenerating Powers of Human Milk Molecules

What do breast milk, regenerating flatworms, and infected mice have in common? That might sound like a particularly cryptic riddle, but the answer may improve our understanding of the beneficial properties of breast milk and could potentially lead to new therapies for many diseases. In a new study, Charles Serhan and his team from Brigham and Women’s Hospital identified new chemical signals that help resolve bacterial infections and speed up tissue repair and regeneration [1]. They isolated these molecules from human breast milk, mice with self-limiting bacterial infections, and regenerating flatworms called planaria. Read More...
