II. Materials and MethodsSample preparation:

Temperature:- 60-65 C dissolve crystalins

- 40 C filtrate- 55 C in vacuum distill water

- 30 C remove air bubble

Measurement: Controlled shear rate test

IV. Conclusion Category and prediction sorting of honey samples

from different floral and geographical origins by

rheometer

Prediction analysis of the honey samples from both

floral and geographical origins showed that PCA had

the worst result and the best result had SVM model Honey can be categorized by viscosity measurement,

so rheometer is a promising and practical tool for the

rapid kind assessment of the honey samples
