Cm. Papoff et al., INFLUENCE OF TEMPERATURE STORAGE ON THE F OOD QUALITY OF STRAWBERRY-TREE HONEY (ARBUTUS-UNEDO L), Industrie alimentari, 34(335), 1995, pp. 268-273
Samples of strawberry-tree honey harvested the same day but characteri
zed by different water contents (A = 17.4%; B = 21.2%) were stored for
1 year at these temperatures: +4 degrees, +16 degrees and +25 degrees
C (consequently: A4, A16, A25 and B4, B16, B25). The number of yeasts
and, consequently, the ethanol content increased depending on the sto
rage temperature and on the water content of honey; the initial conten
ts of number of yeasts and ethanol of the fresh and +4 degrees C store
d honey were respectively 0.01% compared to the one of B16 for the num
ber of yeasts, and the 0.75% compared to B16 and B25 samples for the e
thanol, after 1 year of storage. The diastase activity, the HMF conten
t and the index of colour seemed to depend only by storage-temperature
factor and compared to the values of the Fresh and +4 degrees C store
d honey, after I year, they were: diastase activity -35% on average in
A25 and B25, -22% on average in A16 and B16; HMF content over +500% o
n average in A25 and B25; index of colour increased from 84 mm Pfund t
o 114 mm Pfund in A25 and B25. From the different data of the assays,
the refrigeration at +4 degrees C of strawberry-tree honey with high w
ater content results indispensable for long storage.
