Summary:
Grain-based materials fermented with Propionibacterium
freudenreichii have enough vitamin B12 to be nutritionally
significant. With the help of Lactobacillus brevis in the
fermentation process, vegans can also be guaranteed a sufficient
and safe B12 intake directly from grain-based food, without pills.



FULL STORY ========================================================================== Vitamin B12 is an essential micronutrient that is needed for functions
such as maintaining the nervous system and forming blood cells. However,
B12 is mainly found in food of animal origin. Those who consume only
small amounts of animal products or are vegan must therefore take B12
in the form of pills or eat food to which industrially produced B12 has
been added.


==========================================================================
"In situ fortification of B12 via fermentation could be a more
cost-effective alternative. And as a commonly consumed staple food,
grains are excellent vehicles for enrichment with micronutrients,"
explains Chong Xie from the Faculty of Agriculture and Forestry,
University of Helsinki, about the background of his doctoral dissertation.

Xie used 11 different grain-based materials and fermented them with Propionibacterium freudenreichii -- the only B12-producing micro-organism accepted for food products.

Propionibacterium freudenreichii, the essential microbe in Emmental
cheese, produced nutritionally significant amounts of vitamin B12 in
most of the fermented grain materials. During the three-day fermentation process, rice bran and buckwheat bran had the highest B12 production. The addition of Lactobacillus brevis was able to dominate indigenous microbes during fermentation and greatly improved microbial safety during the fermentation process.
