Rice bran: During enzymatic bioprocessing, enzymes come in contact with the complex interior. Soon after they begin to break the bonds between the complex network and bioactive molecules into small pieces and release the bioactive molecules
This entire process not only enriches me with various easily available bioactive molecules but also
For an easy understanding of how enzymes work, I would like to explain using this picture.
Consider this tightly woven mat as a complex network.
Multiple coloured beads as individual bioactive molecules trapped in the mat.
Different coloured scissors as different enzymes.
By using a suitable scissor, threads responsible for keeping the mat intact and trapping the coloured beads can be cut and release colored beads.
At times, coloured beads can be released efficiently by using single scissors and some time, two or more scissors may be necessary.
Similarly, enzymes work on complex interior and eventually release the trapped bioactive molecules.
Host: Interesting!Have you
undergone through enzymatic bioprocessing?
Rice Bran: Yes. I will share my latest experience. Since 2016, a research group at CSIR- Central Food Technological Research Institute
(CSIR- CFTRI) is working on enzymatic bioprocessing of my red variety (red bran).
At first, the group treated me with enzymes
specialized in breaking the complex network and releasing the bioactive molecules.
The research group used five enzymes having different levels of activity called Endo- xylanases 1 and 2, Cocktail enzymes 1 and 2 and an enzyme mix containing both Endo-xylanase 1 and Cocktail enzyme 1.
The main aim of the research group was to know the efficiency of these specialized enzymes and the type of bioactive molecules released by them.
Host:What did they find out? Rice bran:The research group found that each enzyme was
efficient in releasing a specific bioactive molecule, known to have a strong health beneficial property.
Free radicals are the atoms that cause damage to proteins, lipids, and DNA within healthy human cells. The damage leads to the increased number of diseases such as blockage of blood vessels, the inadequate blood supply to heart, heart failure, Alzheimer’s disease, rheumatic arthritis, cancer, and other disorders of the immune system.
