By Bhavna KavetiSep 5 2022Reviewed by Susha Cheriyedath, M.Sc. Food fortification with supplements improves the quality and quantity of the nutrients in food. An article published in the journal Scientific Reports presented the preparation of microcapsules loaded with selenium nanorods and probiotics to enhance the nutritional content of stirred yogurts.
The microcapsules were loaded with varying concentrations of Se nanorods and probiotics , had irregular shape and efficiency between 95.25 and 97.27%. These microcapsules could resist the degradation by gastrointestinal juices and showed a minor inhibition effect against Caco-2 and HepG-2 cell lines.
Related StoriesNanorods are nanostructures that are extensively used in fundamental and applied research. These nanomaterials may be prepared from carbon, gold, zinc oxide, and many other materials and are larger in size than individual atoms and small molecules. Probiotics are a group of microbes associated with food to enhance their nutritional value and maintain gut health. Probiotics are highly promoted for their ability to support gastrointestinal health and strengthen the immune system. Currently, the consumption of probiotic cells via food products is in high demand. Probiotics are also considered functional foods that are foods that look like traditional foods yet have established physiological benefits.
The Se nanorod and probiotic-loaded microcapsules showed anti-proliferative activity against Caco-2 and HepG-2 cell lines. The microcapsules concentration of 1000 micrograms per milliliter showed 44.26 and 37.46% inhibition against Caco-2 and HepG-2 cell lines, respectively. Moreover, pure green Se nanorods showed high antimicrobial against both gram-positive and gram-negative bacteria.
Microcapsules loaded with Se nanorods and probiotics had an irregular and rough surface and showed efficiency in the range of 95.25 and 97.27%. The microcapsules were resistant to digestion in the gastrointestinal system, showing maximum probiotic counts after 4 hours in stimulated colonic solution.
