introduction: active packaging is one of the innovations in food packaging industry that would be a respons to the changing needs of consumers and markets. in this technique, materials such as adsorbents oxygen, moisture, carbon dioxide, ethylene and carbon dioxide-releasing flavor compounds, antimicrobials, antioxidants and various aromatic compounds are used. in the last decade, great attenti...

The essential oils isolated from basil (Ocimum sp.), chamomile (Chamomilla recutita L.), thyme (Thymus vulgaris L.) and oregano (Origanum sp.) were analysed rapidly and non-destructively applying different vibrational spectroscopic methods (ATR-IR, NIR and Raman spectroscopy). Whereas NIR spectroscopic data can be interpreted only by application of chemometric algorithms, IR and Raman spectra o...

The purpose of this project is to propose a quick and environmentally friendly alternative to measure the quality of oils used in food industry. There is evidence that repeated and indiscriminate use of oils in food processing cause physicochemical changes with formation of potentially toxic compounds that can affect the health of consumers and cause organoleptic changes. In order to assess the...

Crude oil is one of the most important energetic resources in the world. It is used as raw material in numerous industries, including the refinery-petrochemical industry, where crude oil is refined through various technological processes into consumer products such as gasoline, oils, paraffin oils, lubricants, asphalt, domestic fuel oil, vaseline, and polymers. Oil-derived products are also com...

Hydrocarbon oils of the alga Botryococcus braunii, extracted from a natural "bloom" of the plant, have been hydrocracked to produce a distillate comprising 67% gasoline fraction, 15% aviation turbine fuel fraction, 15% diesel fuel fraction, and 3% residual oil. The distillate was examined by a number of standard petroleum industry test methods. This preliminary investigation indicates that the ...

In the petrochemical industry, certain elements are known to impact the performance and value of the final product, while others have detrimental effects on petroleum refining processes, as in the case of elements which can deactivate or poison catalysts. Consequently, there are several ASTM methods on the elemental analysis of oils, lubricants and fuels. Multi-Element Analysis of Petroleum Cru...

The authentication of extra virgin olive oil and its adulteration with lower-priced oils are serious problems in the olive oil industry. In addition to the obvious effect on producer profits, adulteration can also cause severe health and safety problems. A number of techniques, including chromatographic and spectroscopic methods, have recently been employed to assess the purity of olive oils. I...
