Lab Results
Pre- & Post- Freeze Drying
Objective: To study the effects of freeze-drying on the nutritional value of breastmilk and if the process is safe from potential introduction of microbes.
Study Method: Breastmilk from the same donor mother was divided equally into four batches with three batches freeze-dried using BioA Trademark Freeze-drying Technique. The fourth batch was kept frozen at -30degC.
Out of the three batches that were freeze-dried, one was chosen to be sent together with the batch kept frozen for nutritional and microbial testing at SGS Testing & Control Services Singapore, a SINGLAS laboratory. The other two freeze-dried batches were kept in our laboratory for further studies. Note that the freeze-dried breastmilk that was tested was reconstituted at a ratio of 1 : 10.
Results: From the results below, we can confirm that our BioA Trademark Freeze-Drying Technique for processing breastmilk is safe, and no microbes were introduced during the process and nutrients in the milk are kept largely the same compared to frozen breastmilk.
3-Years Accelerated Study
Objective: To study the effect of time on the nutritional value of freeze-dried breastmilk and monitor any potential microbial growth.
Study Method: A previous batch of freeze-dried breastmilk that was sealed in moisture barrier mylar bag was placed inside a laboratory grade oven at 55degC for 120 days to simulate aging for 3 years according to test standard ASTM F1980 – Accelerated Aging Laboratory Testing of Medical Devices. This batch was then submitted for nutritional and microbial testing at SGS Testing & Control Services Singapore, a SINGLAS laboratory. Note that the freeze-dried breastmilk that was tested was reconstituted at a ratio of 1 : 10.
Results: From the results below, when compared to frozen breastmilk from the same mother, there was no microbial growth in the freeze-dried breastmilk that had been accelerated aged for 3 years, and nutrients in the milk were kept largely the same compared to frozen breastmilk.
