Resumo(s)
Mono fl oral Lavandula spp. honey is very appre -
ciated by consumers due to its characteristic and pleasant
aroma and fl avor. Given the economic importance of this
type of honey, it is important to develop a rapid and non -
expensive methodology that allows certifying its quality.
In this context, this study aimed to compare the applic -
ability and accuracy of FTIR - ATR and FT - Raman techni -
ques for the quality evaluation of Lavandula spp. honey.
Calibration models, with PLS regression models, were
obtained for both methodologies concerning the following
parameters: total acidity, reducing sugars, hidroximetil -
furfural ( HMF ) , electrical conductivity, ash, proline con -
tent, diastase activity, apparent sucrose, total fl avonoids,
and total phenolic contents. The calibration models had
high regression coe ffi cients, r
2 ( FTIR - ATR: 0.965 – 0.996;
FT - Raman: 0.983 – 0.999 ) , high ratios of performance to
deviation, RPD ( FTIR - ATR: 5.4 – 15.7; FT - Raman: 7.6 – 53.7 ) ,
and low root mean square errors ( RMSEs; FTIR - ATR:
0.005 – 3.0; FT - Raman: 0.004 – 1.02 ) . These results corrobo -
rate the potentiality of FTIR - ATR and FT - Raman for quality
evaluation and evaluation of the chemical properties of Lavandula spp. honey even though FT - Raman technique
provided more accurate models.
