A precision architecture for extending the biological viability of perishable food commodities — with measurable, auditable impact on waste, hunger, and atmospheric carbon.
Post-harvest degradation is not a single event — it is a cascade of interconnected processes: enzymatic oxidation, microbial colonisation, cellular membrane rupture, and ethylene-driven senescence. Legacy preservation methodologies intervene at one or two of these vectors. Our platform is designed to interrupt all four simultaneously.
The Sam Preservation formulation is a multi-modal treatment system — a precisely engineered combination of approved food-safe substances and novel functional actives, designed to create what we term a "Preservation Field": a controlled microenvironment at the cellular interface that dramatically slows the thermodynamic progression toward spoilage.
Unlike ethylene inhibitors or sulphite-based preservatives, our compounds are designed not to alter the sensory profile of treated produce. They operate at the biochemical level, leaving macronutrient integrity, flavour volatiles, and textural properties fully intact — a critical differentiator for premium produce markets where quality standards are non-negotiable.
This approach is informed by extensive research in applied food science, validated through controlled shelf-life trials, third-party microbiological testing, and real-world deployments across tropical, Mediterranean, and sub-Arctic logistics corridors.
Disruption of polyphenol oxidase and lipoxygenase enzymatic activity — the primary drivers of browning, off-flavour development, and cellular breakdown in fresh produce.
A functional surface treatment that creates a selectively permeable barrier against bacterial and fungal colonisation without compromising gas exchange or produce respiration rates.
Targeted interference with ACC synthase — the rate-limiting enzyme in ethylene biosynthesis — to delay the hormonal ripening cascade in climacteric fruit.
Phospholipid bilayer stabilisation through targeted co-factor supplementation, reducing the rate of cellular turgor loss and delaying the irreversible textural deterioration associated with chill injury.
