Same relations as the 3D bench:
HMF = 2 + 95 (heat/100)^1.4 limit 40 mg/kg
DN = 32 (1 - (heat/100)^0.9) limit >= 8
moisture <= 20 % (refractive index RI = 1 + 10^(-0.2681 - 0.002243 m))
pollen = 90 (0.55 + 0.4 (1 - heat/140)), syrup: 6 %
Heating raises HMF and destroys diastase together; a syrup sample carries almost no pollen. The verdict passes only if all four tests agree.
