Use of silver fir (Abies alba Mill.) bark extract for preparation of beekeeping products |
Sekundarni povzetek: |
The purpose of our thesis was to gain new honey analogous beekeeping product by
feeding the bees with fir bark extracts (Abies alba Mill.) and to assess the
suitability of the product as honey in addition to daily human consumption. In this
regard, we first had to determine the appropriate concentration of the extract, by
testing which concentrations would the bees prefere. After finding out an appropriate
concentration, we prepared large quantities of solutions and fed the bee colonies per
supply. The first colony was fed with dry extract and the other with liquid extract, the
third colony only with sugar solution and all three solutions were supplemented with
beetroot juice. The gained product and food were used for further testing with
spectrophotometer, where we found that the quantity of beetroot juice and of the
extract were less in the product. Similar, trend was demonstrated using the
Folin-Ciocalteu's method. We have also carried out sensory analysis of four kinds of
honey, including our product. We demostrated that the bark fir extract was present in
the product, however we would have to devote some attentions to oxidation of
beetroot pigments besides the technolohy of feeding. |

Namen dela je bil pridobiti nov medu podoben čebelarski proizvod s hranjenje
čebel z izvlečkom lubja jelke (Abies alba Mill.) in oceniti primernost proizvoda kot
dodatek vsakodnevni človeški prehrani. Da smo prišli do medu podobnega proizvoda,
smo najprej morali ugotoviti primerno koncentracijo izvlečka, kar smo naredili tako
da smo testni družini na sate postavili posodice z različnimi koncentracijami. Ko smo
ugotovili primerne koncentracije smo pripravili večje količine raztopin in čebelje
družine krmili na zalogo. Prvi družini smo krmili hrano s suhim izvlečkom, drugi pa s
tekočim izvlečkom, tretjo družino smo krmili samo s sladkorno raztopino, vsem trem
pa je bil dodan pesin sok. Pridobljeni proizvod in hrano smo uporabili za nadaljnja
testiranja s spektrofotometrom, kjer smo ugotovili, da je pesinega soka in posledično
izvlečka bilo manj v proizvodu kot v hrani. Podobno smo dokazali tudi s Folin-
Ciocalteujevo metodo. Izvedli smo tudi senzorično analizo štirih vrst medu, med
katerimi je bil tudi naš proizvod. Dokazali smo, da je bil proizvod prisoten v izdelku,
vendar bi poleg tehnologije hranjenja morali nekaj pozornosti nameniti oksidaciji
pesnih barvil. |
