FORMULASI SEDIAAN SABUN PELEMBAB TRANSPARAN YANG MENGANDUNG MINYAK BIJI BUNGA MATAHARI (Sunflowerseed Oil)

Minyak biji bunga matahari mengandung vitamin E yang dapat dimanfaatkan untuk industri farmasi, termasuk kosmetik. Telah dilakukan penelitian mengenai formulasi sediaan sabun pelembab transparan yang mengandung minyak biji bunga matahari dengan berbagai konsentrasi minyak biji bunga matahari (0, 5, 10, 15%b/b). Penelitian ini bertujuan untuk membuat formulasi sediaan sabun pelembab transparan dengan berbagai konsentrasi minyak biji bunga matahari (Sunflowerseed Oil) untuk melembabkan dan melembutkan kulit. Penelitian dilakukan dengan mengamati stabilitas fisik sediaan sabun pelembab transparan yang meliputi stabilitas fisik sediaan sabun pelembab transparan yang meliputi stabilitas fisika (organoleptis, homogenitas), uji stabilitas kimia (pH), dan pengujian terhadap sukarelawan menggunakan alat Skin Analyzer. Hasil penelitian menunjukkan bahwa sediaan sabun pelembab transparan mulai memberikan efektivitas melembabkan pada formula yang mengandung minyak biji bunga matahari 5% (F1) dan pada formula F2 (10%) merupakan formula yang paling disukai karena nyaman dalam penggunaannya. Hasil penelitian juga menunjukkan bahwa sediaan sabun pelembab transparan dengan konsentrasi 5%, 10% dan 15% aman digunakan.Kata kunci : minyak biji bunga matahari, sabun transparan, skin analyzer

Effects of storage condition on the physicochemical characteristics of sunflower seed oil

Sunflowerseed oil needs a low-temperature and dark condition to remain flavor by reducing the changes of 3-methyl-2,5-furandione, hexanal and 2-heptenal.

Pengaruh Temperatur Terhadap Degradasi Pigmen Tomat dalam Beberapa Jenis Minyak Nabati Komersial

The study of vegetable oils fortified with crude extract of carotenoid pigments from tomatothat contains lycopene as dominant antioxidant compounds becomes an interesting researchto be done. The aim of this research is testing the stability of the pigment of tomatoesextracts in the vegetable oil treated on some temperature levels. Spectroscopy method isused to measure the respond of pigment stability in fortified vegetables oils which treated bytemperature from 250C to 700C. Before the measurement is done by a spectrophotometerwhich connected to the thermostat, as much as 1 mg of extract pigment of tomatoes in crystalform was weighed for per sampel, then dissolved into 10 ml palm oil, coconut oil, sunflowerseed oil, and canola oil separately. The results showed that the temperature treatment causesthe value of the optical absorption decreased, which means that the pigment moleculesexperienced instability. The amount of impairment of the optical absorption withtemperature treatment from 250C to 700C at a wavelength of 482 nm, respectively, are: palmoil (Abs = 0.201); coconut oil (Abs = 0.213), sunflower oil (Abs = 0.232); and canola oil(Abs = 0.260). Decreasing value of absorbance (Abs) also indicates the lycopenedegradation that formed the derivatives molecule of this pigment.Keywords: fortification, lycopene, vegetable oil, temperature, tomato

Pancreatic enzyme secretion in response to test meals differing in the quality of dietary fat (olive and sunflowerseed oils) in human subjects

The aim of the present study was to investigate in human subjects whether or not the ingestion of two liquid meals that differed only in their fatty acid composition (due to the addition of olive oil (group O) or sunflowerseed oil (group S) as the source of dietary fat) would lead to differences in the pancreatic enzyme activities secreted into the duodenum. The experiments were performed in eighteen cholecystectomized subjects who, during the 30d period immediately before surgery, modified their habitual diets in such a way that their fat composition would reflect, as far as possible, that of the experimental meals. Lipase (EC3.1.1.3), colipase, amylase (EC3.2.1.1), chymotrypsin (EC3.4.21.1) and trypsin (EC3.4.21.4) activities were measured in duodenal contents aspirated before and after the ingestion of the test meals. The plasma levels of secretin and cholecystokinin (CCK) were also examined. Duodenal enzyme activities were similar in resting conditions. No significant differences were revealed in postprandial enzyme activities, except for lipase activity, which was higher in group O, probably in relation to the greater plasma CCK concentrations observed in this group. In the absence of enzyme output data, we should not exclude the possibility that the type of dietary fat will affect human pancreatic enzyme secretion to a greater extent than is evident from the present study, for instance through a flow-mediated effect, as we previously observed in dogs.

Effect of dietary fats rich in lauric, myristic, palmitic, oleic or linoleic acid on plasma, hepatic and biliary lipids in cholesterol-fed hamsters

Effects of different dietary fats on plasma, hepatic and biliary lipids were determined in male golden Syrian hamsters (Mesocricetus auratus) fed on purified diets for 7 weeks. Diets were made by blending different fats containing characteristic fatty acids: butter (14:0 + 16:0), palm stearin (16:0), coconut oil (12:0 + 14:0), rapeseed oil (18:1), olive oil (18:l) and sunflowerseed oil (18:2). In all diets except the sunflowerseed oil diet dietary 18:2 was held constant at 2% energy. Total fat supplied 12% of energy and cholesterol was added at 4 g/kg diet. Plasma cholesterol and triacyglycerol concentrations were increased by dietary cholesterol. After 7 weeks, plasma cholesterol concentrations were highest with the palm Stearin, coconut oil and olive oil diets (8·9, 8·9 and 9·2 mmol/l) and lowest with the rapeseed oil and sdowerseed oil diets (6·7 and 5·5 mmol/l) while the butter diet was intermediate (8·5 mmol/l). Hepatic cholesterol concentration was highest in hamsters fed on the olive oil diet and lowest with the palm stearin diet (228v. 144 µmol/g liver). Biliary lipids, lithogenic index and bile acid profile of the gall-bladder bile did not differ significantly among the six diets. Although the gallstone incidence was generally low in this study, three out of 10 hamsters fed on the palm stearin diet developed cholesterol gallstones. In contrast, no cholesterol gallstones were found with the other diets. Rapeseed and dowerseed oils caused the lowest plasma cholesterol and triacyglycerol concentrations whereas olive oil failed to demonstrate a cholesterol-lowering effect compared with diets rich in saturated fatty acids. Since 18:2 was kept constant at 2% of energy in all diets, the different responses to rapeseed and olive oils could possibly be attributed to their different contents of 16:0 (5·6 %v. 12·8% respectively). Other possible explanations are discussed.
