Salvia officinalis L.
Common sage, Great sage,
Dalmatian sage,...
Spontaneous perennial plant
characteristic for the rocky pastures of
the Eastern Adriatic sub-Mediterranean
area, especially islands

Sage honey
One of the most appreciated
honeys of Croatia
Reaching highest prices.
Adaptation of the market
interest to the natural
“insticts” of producers
Manipulation – partial
(or complete) supstitution
with honeys of “lower values”

Melissopalynology asessement
• Other nectarous species (total 106):
– Specially useful tool for overall characterization
– Higher representation: – Rhamnaceae
• (A: 22,45 %; B: 20,41 %; C: 34,69 %)
– Followed by Acer, Castanea as well as Myosotis, Prunus and
Rubus
• Pollen spectar of non-nectarous plants (total 35)
– Quercus robur gr., Oleaceae (95,92 %)
– Identified in more than 50 % samples:
• Graminaceae (85,71 %), Plantago (81,63 %), Poterium (71,43 %),
Cupressaceae (69,39 %), Cistaceae (65,31 %), Filipendula (65,31 %) ,

Physical and chemical analysis
Expressed seasonal
influence on distribution of
most of the parameters,
especially for 2007
Heavy influence of climatic
elements on range and level
of the analytical parameters
“favouring ” the honeydew
intake
Honey still keeping its
blossom character
Sensory asessment
Tranined panel assessment:
 Visual properties
 Olfactory properties
 Taste properties
 Tactile properties
 Presence/absence of defects
Comprehensive judgment of
unifloral compliance and
overal sensory quality

aboundance as well as energy consumption, most economic

Sensory assessment
• Visual assessment
– Color intensity: medium to dark
– Color tone: jade (normal color)
• Olfactory assessment
– Intensity of odor: medium
– Description: chemical, medicinal
herbs, gentle, camphor; warm
– Also perceptible:
• Some floral notes of dry and aromatic
flower
• Vegetal green notes (fresh rubbed
leaves)
• Slightly clue of burned or cooked fruit
Sensory assessment
• Taste assessment
–

–
Sweetness: medium
Bitterness: medium
Acidity: medium
Intensity of aroma: medium to medium/strong
• Description of aroma:
– Immediately strongly medicinal and warm, then
floral notes of dry aromatic flowers are
perceived...
– Bitter aftertaste
– Resemblance to medicine, vegetal green
– Distinctive herbs liquor or bitter almond...
– Medium persistence and slightly astringent...
