Since the rose water is used in food, pharmaceutical, and cosmetic products, its microbiological control is necessary. Conventional pasteurization methods cause undesirable changes in taste, smell, medicinal properties and nutritional value with decreasing the amount of essential oil, because of high temperatures. In this study, the effects of the microwave power, temperature, ultrasound power,...

Geranium oil is known as a floral substitute of rose essential with its pungent rose-like odor and one the most valuable oils. Favorable quality properties make geranium exigible for food industry applications. This study determined chemical fingerprint using robust vibrational spectroscopy techniques (Fourier transform infrared Raman spectroscopy). The mid-infrared characterization was accompl...

The essential oil yield stability of damask rose (Rosa damascena Mill.) as an important medicinal and aromatic plant in different environments has not been well documented. In order to determine appropriate stability parameters, six statistics were studied for essential oil stability of 35 Rosa damascena landraces in seven locations (Sanandaj, Arak, Kashan, Dezful, Stahban, Ke...

A major concern (or opportunity?): The price of oil was growing very rapidly, from $28 in 2003 to $38/barrel in 2005 and occasionally to above $80 in 2006 and peaking at $147 in 2008, but then precipitously dropping to $40 by the end of 2008. The peak price is 1–2 orders of magnitude higher than the cost of extraction, possibly meaning that financial speculation is overwhelming supply and deman...

Four years ago, as the temperature of rhetoric in the food-versus-fuel debate rose with the prices of corn and oil, Farm Foundation asked three economists from Purdue University to take an objective look at the complex forces that were driving food prices. While oil prices are not at 2008 levels this summer, drought and high temperatures are pushing corn and soybean prices to record levels, and...

This research was aimed at investigating the antioxidant and antibacterial activity of Bunium persicum, Eucalyptus globulus, and rose water on multidrug-resistant Listeria species. The antibiotic resistance of Listeria spp obtained from seafood samples were determined by the Kirby-Bauer method. The antioxidant and antibacterial activity of the essential oils and extracts were evaluated using fe...

PURPOSE An oil in water emulsion of 0.01% all-trans-retinoic acid (tretinoin) was prepared and clinically evaluated in dry eye patients. METHODS The ophthalmic emulsion consisted of 10% of arachis oil and 90% of the hydrogel of Carbopol 940. To evaluate retinoic acid emulsion clinically, a placebo-controlled, open-labeled, randomized study was performed with 22 dry-eye patients. Symptoms were...

Pulses of oil were added to completely mixed reactors fed with dairy cow manure and food waste, after achieving a stable performance at an organic loading rate of 4.6+/-0.1gCOD/(l(reactor) day), an oily waste effluent from a canned fish processing industry was fed in the form of pulses. The oil concentration rose up to 9, 12, 15 and 18gCOD(oil)/l(reactor,) after the pulse feeding in the reactor...
