In brief
Definitions and unit conventions used throughout the FlavoRotor research record.
Core definitions
| Term | Operational definition |
|---|---|
| Taste | Basic gustatory perception such as sweet, sour, bitter, salty or umami |
| Aroma | Olfactory contribution arising predominantly from volatile compounds |
| Flavour | Combined taste, aroma, texture, trigeminal and contextual perception |
| Texture | Mechanical and structural perception measured instrumentally and/or sensorially |
| Recipe | Versioned schedule of measurable cultivation setpoints and actions |
| Biological replicate | An independently grown plant or experimental unit |
| Technical replicate | Repeated measurement of the same biological sample |
| Independent cycle | A cultivation run started at a separate time with a new biological batch |
Required units
| Quantity | Symbol | Unit |
|---|---|---|
| Hydrogen-ion activity | pH | dimensionless logarithmic activity scale |
| Electrical conductivity | EC | mS/cm, temperature reported |
| Photon flux density | PPFD | µmol·m⁻²·s⁻¹ |
| Daily light integral | DLI | mol·m⁻²·d⁻¹ |
| Temperature | T | °C |
| Relative humidity | RH | % |
| Vapour-pressure deficit | VPD | kPa |
| Angular speed | n | rev/min |
| Angular velocity | ω | rad/s |
| Flow | Q | mL/min |
| Concentration | c | mmol/L or mg/L, species stated |
| Fresh/dry mass | m | g |
Reporting rules
- EC is always reported with solution temperature or temperature compensation.
- pH is reported with calibration date, buffers and electrode identifier.
- Light is reported at plant position, not inferred only from electrical wattage.
- Concentration values identify the chemical species and basis, for example mg/L K rather than “potassium EC”.
- Mean values include variability, sample size and the experimental unit.
Metrology source
Accuracy, precision, repeatability, resolution, calibration and uncertainty are used according to international metrology vocabulary and guidance.
