## Overview and value chain

Markers: [EC: Food Supplements Directive 2002/46/EC | OECD: Food Systems | Regulator: FDA (USA), EFSA (EU), NMPA (China)]

Bioactive peptides are short chains of 2–20 amino acids, locked inside large
plant or animal protein globulins in their native state but released as potent
cell-signalling molecules once freed. Unlike bulk dietary protein that serves
mainly as a plastic amino-acid source, these peptides act on receptors in the
gut, immune system, vasculature and muscle, triggering specific metabolic
cascades. The 2026 industry is defined by an AI-discovery revolution:
generative platforms such as Nuritas Magnifier and Brightseed Forager scan
trillions of candidate sequences in plant genomes, predicting bioactivity,
gastrointestinal stability and target binding, and compressing ingredient
discovery from a 5–7 year wet-lab campaign to a matter of months. The
flagship plant peptide complex PeptiStrong, isolated by AI from faba bean
(Vicia faba), down-regulates the muscle-atrophy genes Atrogin and MURF1 and
has cleared FDA GRAS for use in foods, drinks and supplements.

The key directions of bioactive peptides for nutrition are:
1. **AI-peptide discovery (AI-Peptide Discovery):** deep-learning screening of plant genomes for latent bioactive motifs, cutting lead time from 5–7 years to months.
2. **Targeted enzymatic hydrolysis (Targeted Enzymatic Hydrolysis):** controlled proteolysis with bespoke protease cascades that cut the protein only at AI-specified sites, yielding a defined peptide pattern.
3. **Membrane downstream fractionation (Membrane Downstream Fractionation):** tangential-flow ultrafiltration with a sharp molecular-weight cut-off (<3 kDa) that isolates ultra-short signalling peptides from larger allergenic fragments.
4. **Functional nutrition formats (Functional Nutrition Formats):** GRAS-grade peptide ingredients formulated into sports recovery, sarcopenia/longevity, infant and enteral-clinical products.

### traditional feedstock peptides, infant & clinical nutrition, MARA standardization
- **Peptides from traditional feedstock:** research centres, including the Chinese Academy of Agricultural Sciences, derive bioactive peptides from soy, rice, wheat, ginseng and marine organisms, with domestic AI screening platforms for medicinal-herb phytochemistry.
- **Infant & clinical nutrition:** deep-hydrolysis peptides are widely built into hypoallergenic infant formula and enteral clinical-nutrition products for bedridden and post-surgical patients.
- **Standardization & state regulation:** MARA and the National Health Commission are developing national standards for functional peptides to order a fast-growing market and protect consumers from adulteration.

## EU

The European Union prioritizes scientific evidence, safety and environmental sustainability of peptide ingredients, acting as the principal R&D base for fundamental peptidomics research and AI-discovery start-ups.

### R&D base & peptidomics, EFSA health-claim control, Green Deal upcycling
- **R&D cradle:** Nuritas was founded by Nora Khaldi in Dublin with European grant support and the Irish National Institute for Food Research; Ireland and Denmark remain the key fundamental peptidomics centres, alongside University College Dublin research on plant hydrolysates and metabolic-syndrome markers.
- **Strict EFSA control:** health claims for peptides undergo the most rigorous EFSA verification, requiring randomized placebo-controlled clinical evidence that screens out pseudo-scientific supplements.
- **Green Deal agenda:** peptide production is framed as part of the transition to sustainable plant feedstock, with enzymatic upcycling of food-industry side streams from oat, pea and lupin subsidized under Horizon Europe.

## Tech stack and innovations

The AI-peptide stack fuses generative bioinformatics with precision bioprocess engineering, where a 1 °C temperature or 0.1 pH shift at the hydrolysis step can change the protease cleavage site and destroy a batch's bioactivity.

1. **AI platforms and predictive modelling (In-Silico Prediction):**
   - deep convolutional networks analyze plant protein structure to flag fragments that, once released, interact with cell receptors (e.g. down-regulating NF-kB-driven inflammation).
   - digestion simulation filters for resistance to pepsin, trypsin and gut peptidases, keeping only motifs that reach the intestine intact and absorbable.
2. **Precision enzymatic hydrolysis (Precision Enzymatic Hydrolysis):**
   - given the AI cleavage map, technologists deploy commercial proteases (e.g. alcalase, papain, thermolysin) in reactors with tight parameter hold, because a 1 °C or 0.1 pH deviation shifts the cut site.
   - the reaction is arrested by rapid heating to 90 °C for 10 min, irreversibly denaturing the proteases before peptides degrade to inactive free amino acids.

#### Stage 1: AI design and protease selection
The Magnifier platform models the cleavage of faba bean protein and selects a specific cascade of two commercial bacterial proteases that excise the PeptiStrong peptide pattern with minimal formation of free amino acids.

#### Stage 2: Isolate preparation and dissolution
Plant faba-bean isolate with >85% protein is dissolved in deionized water to 10% dry solids, heated to 55 °C and set to pH 8.0 with sodium-hydroxide dosing for the first protease.

#### Stage 3: Directed controlled proteolysis
The first protease is dosed in and hydrolysis runs for 4 hours under continuous mixing, with a pH-stat auto-dosing alkali to neutralize freed carboxyl groups; a second protease then finishes cutting the peptide chains.

#### Stage 4: Thermal inactivation of enzymes
To stop the peptides degrading to inactive free amino acids, the mass is flash-heated to 90 °C and held for 10 minutes, irreversibly denaturing the proteases.

#### Stage 5: Microfiltration and cascaded ultrafiltration
The hydrolysate is cooled to 45 °C, centrifuged to remove insoluble fibre, then pumped through a tangential-flow cascade: a 10 kDa membrane removes undigested protein and denatured enzyme, and a 3 kDa membrane removes mid-size peptides, leaving a permeate of ultra-short signalling peptides under 3 kDa.

#### Stage 6: Concentration, drying and packing
The peptide solution is vacuum-concentrated to 35% solids and spray-dried (175 °C inlet, 80 °C outlet); the light-cream hygroscopic powder at <4% moisture is packed in nitrogen-flushed foil pouches for B2B delivery to sports-nutrition and supplement manufacturers.
