- Pripravili in ovrednotili smo prehranske
dodatke z antioksidacijskimi lastnostmi, ki pri
termi~ni obdelavi in skladi{~enju prepre~ujejo
oksidacijski razpad jedilnih olj. Pri~akujemo,
da bodo te u~inkovine zagotavljale kontrolirano
stabilnost olj in drugih izdelkov na bazi
ma{~ob (majoneza, smetana, mleko, itd).
- Dokon~ali smo projekt »Su{ilnik za programirano
su{enje TLC plo{~«. Izbrali smo ustreznega
proizvajalca, to je podjetje Iskra PIO
d.o.o. iz [entjerneja in skupaj z njim smo
pri~eli tr`iti izdelek. Su{ilnik je pri uporabnikih
dobil zelo pohvalne ocene, ker omogo~a
su{enje v zaprtih in kontroliranih pogojih in s
tem isto~asno izbolj{a ponovljivost analiznih
meritev in pove~a po`arno varnost. Izdelek
ima slovenski patent in je v fazi patentiranja
v nekaterih evropskih dr`avah.
- Za vodotopno obliko koencima Q10 (CoQ10)
smo v letu 2005 vlo`ili mednarodno patentno
prijavo PCT/SI2005/000013 in zanjo v
Sloveniji `e prejeli patent {t. SI 21807. Za
proizvodnjo in tr`enje tega izdelka smo
sklenili pogodbo s podjetjem Valens Int.
d.o.o., Ljubljana, ki je pri~el s tr`enjem
vodotopnega CoQ10 pod za{~itno znamko
Q10Vital. Sodelovali smo pri pripravi
mednarodnega simpozija »Dan koencima
Q10«, ki je potekal 10. novembra 2005 v
Ljubljani. Simpozija se je udele`ilo pribli`no
100 doma~ih in tujih udele`encev. Na
simpoziju smo predstavili vlogo konencima
Q10 v ~love{kem organizmu in prednost
na{ega izdelka v primerjavi z nevodotopnimi
in vodotopnimi oblikami tujih proizvajalcev.
- Pripravili smo pilotno proizvodnjo vodotopnega
Q10. Ob tem, da so na trgu `e prvi
proizvodi narejeni po na{i licenci, smo
nadaljevali z razvojem in testiranjem novih
prehrambenih izdelkov. Pripravili smo mleko,
jogurt, kefir, ~okoladne izdelke, sadne sokove
in celo mineralno vodo obogateno s CoQ10.

- The project »Programmable TLC dryer« was
completed and the firm PIO d.o.o., [entjernej,
Slovenia was selected as a producer of commercially
available instrument.
- The international patent application No. PCT/
SI2005/000013 was submitted for our water
soluble form of Coenzyme Q10 and the
Slovenian patent No. SI 21807 was granted
for the same. Together with our partner
Valens Int. d.o.o., Ljubljana, Slovenia, we
started to sell our product under the name
Q10Vital. We co-organised the International
symposium on Q10, which took place in
Ljubljana on 10th November 2005. Nearly 100
participants attended this symposium. Our
group presented the role of Q10 in human
body and advantages of our water soluble
form in comparison to other products on the
market.
- We succeeded in preparing a pilot production
of water-soluble Q10. While products
made using our licence are already on the
market, we have continued with the development
and testing of new food items. Milk,
yogurt, kefir, chocolate products, fruit juices
and even mineral water were enriched with
coenzyme Q10. All products were then characterized
for their chemical and organoleptic
properties, as well as stability. In addition,
we developed a synthesis for cyclodextrin
complexes with new substances and continued
the search for acceptable carriers for the
water-soluble CoQ10 preparation.
- The stability of polyphenols in juices made
from blackcurrant using different maceration
methods was evaluated. Concentrates from
blackcurrant were also added to strawberry
juices in order to enrich their colour and antioxidant
activity, especially during storage at
room temperature. After processing and during
the storage, these new products were
tested. The content of total polyphenols,
anthocyanins, antioxidant activity, vitamin C
and individual anthocyanins, flavonols and
phenolic acids were measured. Strawberry
