Inside DETI@ACE TBI: What R&D Actually Looks Like at Phase 0
No glossy labs. No manufactured optimism. This is an honest account of what it actually looks like to run fermentation R&D inside a university incubator — from Run 01 failures to the protocol we have now.
Every startup that touches “biotech” eventually has to answer the same uncomfortable question: where, exactly, is the science happening? For some, the answer involves rented clean-room space in a pharmaceutical hub. For us, at this stage, the answer is DETI@ACE TBI at Adhiyamaan College of Engineering, Hosur.
I want to be honest about what that means in practice, because the biotech founder narrative tends to sanitise early-stage R&D into something that sounds more polished than it is.
What Phase 0 Actually Looks Like
Phase 0, in our context, means: we do not yet have a validated, reproducible fermentation protocol. We have a hypothesis — that LAB fermentation of Ragi and Karuppu Kavuni (Black Rice) substrates can meaningfully reduce phytate concentration and enhance mineral bioavailability — and we are running systematic experiments to test whether that hypothesis holds under controlled conditions.
Run 01 did not work. The inoculation density was off, and the fermentation stalled after six hours. Run 02 taught us something about substrate moisture that we had not accounted for. Run 03 was the first time we got a measurable CO2 evolution curve, which suggested active fermentation but we still had no bioassay data to confirm phytate reduction. Each run costs money, time, and a non-trivial amount of Ragi flour.
Current Status — Apr 2026
We are on Run 05. The protocol has stabilized sufficiently that we are now able to run phytate colorimetric assays post-fermentation. Preliminary readings suggest measurable reduction vs. unfermented control. Formal validation is pending. We will publish those numbers when they are confirmed.
Why We Pitched a TBI Instead of a Contract Manufacturer
The first instinct when building a food product is to go straight to a contract manufacturer: they have equipment, they have process engineers, they have regulatory compliance. But every contract manufacturer we spoke to in the early phase had the same advice — simplify the formula, use extrusion instead of fermentation, use maltodextrin as a carrier. The economics of their business do not accommodate low-volume, slow-process, innovation-led formulation work.
DETI@ACE TBI understood the brief immediately when we pitched the idea. We were not pitching a consumer product — we were pitching a primary R&D programme aimed at understanding whether fermentation could be systematically used to improve the bioavailability of micronutrients in traditional Indian grains. The TBI gave us lab access, mentorship access, and institutional credibility in exchange for being part of India’s growing deep-tech incubation ecosystem.
“If you want to build a cheap product, there are a thousand factories ready to help you. If you want to build something real, you have to own the research environment first.”
The Honest Realities of Incubation
Incubation is not glamorous. The lab hours are shared. Equipment booking sometimes conflicts with other researchers’ needs. There are days where the fermentation run produces nothing useful and you have to start over. The data is messy and inconclusive in ways that no pitch deck ever acknowledges.
But these constraints are, counterintuitively, what make the output credible. Every run we document, every failed protocol, every colorimetric reading — it builds an evidence trail. When we eventually have a validated formula, it will not be the result of a marketing team deciding what nutrients to list on a label. It will be the result of a systematic research process that documented every failure on the way to a result that works.
What Comes Next
Once Run 05 is complete and phytate reduction is formally validated, the next phase is organoleptic testing — understanding what the fermented substrate tastes, smells, and feels like, and whether it can be formulated into a consumable product without destroying the bioavailability gains we are creating in the fermentation step. That problem is harder than it sounds, and we will write about it in detail when we get there.
We are building this in public because we believe the Indian functional food market deserves to see what honest, evidence-led product development actually requires. If that transparency costs us some early credibility, that is a cost we are willing to pay.
