Best Deep Freezer for Breastmilk Storage: The Ultimate Guide to Choosing a Small Deep Freezer for Your Breast Milk

One of the most crucial factors in a baby’s health and growth is breastfeeding. It offers a unique mixture of nutrients that can’t be found in another form. Breast milk is the ideal nutrition for a baby’s growing digestive system, and it also serves as protection from several ailments and disorders.

The World Health Organization (WHO) advises continuous breastfeeding for up to two years or longer. According to a study, breast milk helps to encourage healthy brain development and may even aid to decrease up to 50% of the risk of Sudden Infant Death Syndrome (SIDS). [1]

Nevertheless, busy moms struggle to feed their infants on time. In this situation, stored breast milk might be the best energy-efficient source of nourishment for a baby whenever a mom isn’t present. In fact, breast milk has Immunoglobulin A (IgA) and lysozyme components that have an antifungal and antiviral capacity.

Research about thawing frozen breast milk was conducted to analyze the effect of the thawing rate of breast milk, it found that compared to fresh milk, the secretory IgA level of breast milk frozen at -18 °C for two months remained steady following thawing up overnight in a freezer (4 °C for 12 h) prior heating to 37 °C. Furthermore, warming breast milk to 25 °C or 37 °C for 30 minutes after it has thawed in the refrigerator overnight may preserve the secretory IgA levels and lysozyme interaction better than heating it right away after taking it out of the freezer. [2]

With this, deep freezers help keep your breast milk frozen for longer periods of time. In this article, you will learn the best freezer for breast milk storage, the most energy-efficient freezer, and how to preserve freshly expressed breast milk properly.
