Oleoegelio su čiobrelių eteriniu aliejumi sudėties moduliavimas ir kokybės vertinimas / The Composition Modeling and Quality Assessment of Oleogel With Thyme Essential Oil

Stukaitė, Aurelija 30 June 2014 (has links)
Pėdų grybelis (lot. Tinea pedis) – tai dermatofitų Trichophyton rubrum, Trichophyton mentagrophytes ir Epidermophyton floccosum sukeltas lėtinis pėdų, kojų tarpupirščių pažeidimas, pasireiškiantis odos įtrūkimais, pleiskanojimu, nemaloniu kvapu ir niežuliu. Vaistinio čiobrelio (lot. Thymus vulgaris L.) eterinis aliejus, savyje turintis timolio (36 – 55 proc.), gali apsaugoti pėdas nuo grybelio atsiradimo. Čiobrelių eterinį aliejų patogu įvesti į aliejinę terpę, tačiau aliejinius tirpalus naudoti nėra patogu. Todėl šio darbo tikslas pagaminti lipofilinį gelį, skirtą pėdų grybelio prevencijai. Šis tyrimas apima: 1) timolio kiekio nustatymą čiobrelių eteriniame aliejuje; 2) optimalaus aliejaus ir gelifikuojančios medžiagos santykio parinkimą; 3) pagaminto lipofilinio gelio su čiobrelių eteriniu aliejumi klampos, pH reikšmės ir išvaizdos įvertinimą; 4) oleogelio veiksmingumo nustatymą, atliekant mikrobiologinį tyrimą. Rezultatai: ESC būdu nustatyta, kad čiobrelių eteriniame aliejuje timolio yra 41,06±0,03 proc. Oleogelio pagrindu nuspręsta naudoti alyvuogių aliejų, nes skystojo parafino ir alyvuogių aliejaus mišinys nesudarė stabilios gelinės struktūros. Pagaminti oleogeliai visą stebėjimo laiką (6 mėn.) išlaikė savo išvaizdą – vientisą struktūrą, skaidrumą, šviesiai geltoną spalvą, čiobrelių kvapą ir pusiau kietą konsistenciją. Atlikus pH reikšmės stebėjimus nustatyta, kad oleogelių pH reikšmė reikšmingai nekito ir išliko atitinkanti žmogaus fiziologinę odos pH reikšmę... [toliau žr. visą tekstą] / Foot fungus (lat. Tinea pedis) is a skin disease caused by dermatophytes Trichophyton rubrum, Trichophyton mentagrophytes and Epidermophyton floccosum. The symptoms are cracks, itch, dandruff and unpleasant odor of the feet skin. Thyme (lat. Thymus vulgaris L.) essential oil containing of 36 – 55 percent of thymol can protect feet from fungus. Thyme essential oil is convenient to introduce in oil medium, but oil solutions are uncomfortable to use. Therefore, the aim of this work is to produce a lipophilic gel for prevention of foot fungus. This study includes the following: 1) determining the amount of thymol in the thyme essential oil; 2) determination of the optimal ratio of oil and gelling agent material; 3) pH value and appearance evaluation of the produced lipophilic gel with thyme essential oil viscosity; 4) the effectiveness of the lipophilic gel in microbiological research. The results: using HPLC method it has been found out that thyme essential oil contains 41.06±0.03 percent thymol. It was decided to use olive oil on oleogel basis because liquid paraffin and olive oil mixture didn’t make stable gel structure. Produced oleogels kept the same appearance features for all observation time (6 months) such as homogenous structure, clearness, light yellow color, the smell of thyme and semi – solid consistency. During the measurement of pH values of oleogels, it has been found out that pH values matched human physiological pH value. During the measurement of viscosity of... [to full text]

Reduction of Saturated Fat in Finely Comminuted and Ground Meat Products by use of Canola Oil Organogels and the effect on Organoleptic Qualities, Texture and Microstructure

Wood, John 13 May 2013 (has links)
The main goal of this research was to determine the effectiveness of saturated fat replacement by means of a canola oil oleogel, termed an “organogel”, using ethyl cellulose (EC, 10 cP) as the gelator and sorbitan monostearate (SMS) as a plasticizer. All-beef frankfurters and pork breakfast sausages were used and instrumental tests performed to determine effectiveness were light microscopy, texture profile analysis, Warner-Bratzler shear force, cook loss and smokehouse yield. A trained sensory analysis panel scored for hardness, juiciness, oiliness, and the presence of off flavours. Replacing beef fat (BF) with canola oil (CO) in frankfurters produced a product that was significantly harder (P < 0.05). The gelling of the canola oil lowered the TPA hardness values. Cohesiveness, chewiness and gumminess values were statistically similar to the BF control. Minor changes in L*, a* and b* values were observed, with the organogel frankfurters being lighter than the BF control. Sensory analysis scores showed that 8,10 & 12% EC frankfurters were significantly less hard than the CO control. / Ontario Ministry of Agriculture, Food & Rural Affairs (OMAFRA)
