Is it Ok to Store Breast Milk in Silicone?

Breast milk is a fresh, living food that, in addition to its nutritional content, has many antioxidant, antibacterial, probiotic and immune-boosting properties for your baby. While these nutritional and health properties change with how and how long it is stored, there is good evidence that breast milk storage is safe and remains the gold standard for infant feeding when direct breastfeeding is not possible. So how to choose the right milk storage bag?

Is it safe to store breast milk in silicone?

During the heating process of breast milk, if the material of the milk storage bag is not safe enough, it will release toxic substances, which may affect the baby's health, so it is necessary to ensure that the materials used in the breast milk bag are non-toxic and harmless.

Food-grade silicone materials that can pass FDA and LFGB certification, can withstand high temperatures of 250°C, and are generally used in baby pacifiers, baby products, medical supplies and electronic products.

As for specific advice on breast milk storage

  1. Usually at room temperature (around 25°C), breast milk can be stored for about 4 hours. If the baby can drink milk within 4 hours, it can be stored at room temperature.
  2. Keep it in an ice pack, and store fresh breast milk in a silicone breast milk storage bag for up to 24 hours.
  3. In the refrigerated state, studies have shown that breast milk can be stored for 48-72 hours at around 4°C. However, if the refrigerator is turned on and off, the temperature will be unstable, so it is best not to exceed 12-24 hours.
  4. Under the freezing condition of minus 18 ℃, breast milk can be stored for 3-6 months.
  5. Frozen at low temperature (minus 20°C), breast milk can be stored for 6-12 months, but it is best to use frozen breast milk within 6 months.
  6. Try to place it as close to the inside of the refrigerator as possible, not near the door. Because during the repeated opening and closing of the door, temperature fluctuations will affect the quality of frozen breast milk.

The refrigerator also needs to meet the following conditions

  1. Need to maintain a constant low temperature: excessive temperature fluctuations will affect the taste and quality of breast milk;
  2. There is a closed sterile space: it is directly mixed with other ingredients in the refrigerator, which is prone to odors and even bacterial contamination.

  3. Use professional disinfection cupboards. If you have a disinfection cupboard at home, you can also wash the silicone breast milk storage bag with water after use, and then put it in the disinfection cupboard to also play a disinfection role.
