vegetable oils and fats have a big contribution in our diet as cooking or frying oil, salad oil or in food products formulation. they are important from nutritional and economical point of views. their authenticity is a serious issue since old time. some edible oils and fats such as olive oil, cocoa butter and milk fat are so expensive which makes tempting to adulterate them with other lower pr...

In this study, the subcritical butane extraction process of fenugreek seed oil was optimized using response surface methodology with a Box-Behnken design. The optimum conditions for extracted oil from fenugreek seed was as follows: extraction temperature of 43.24 °C , extraction time of 32.80 min, and particle size of 0.26 mm. No significant differences were found between the experimental and p...

Seeds are another product in addition to leaves (raw materials for teas) of tea (Camellia sinensis L.) plant. The great increase of tea consumption in recent years raises the challenge of finding commercial applications for tea seeds. In the present study, supercritical carbon dioxide (SC-CO(2)) extraction edible oil from tea seed was carried out, response surface methodology (RSM) was used to ...

Hexane, the common solvent for extraction of edible oils from seeds is no more considered safe due to the presence of solvent in oil and also solvent vapour, a hazardous air pollutant. We have carried out the experiments with bahera (Terminalia bellerica Roxb) and flax seed (Linum usitatissimum ) oil as these oils are highly used in food for their nutraceutical values. The extraction of edible ...

Castor (Ricinus communis L.) is a fast growing plant of marginal and moderately saline land widely spread throughout tropical regions. It is cultivated at arid coastal sandy belt and inland waste land of Pakistan for obtaining oil from its seeds, which being of medicinal importance is an economical commodity. Facing a great shortage of mineral diesel, scientists are nowadays actively working fo...

Background: Edible film is a food packaging that can be eaten directly and have protection function of outside contamination. The purpose of this research is to know how about the effect of using a glycerol plasticizer to film whey-konjac edible films that enriched with clove essential oil. Methods: A completely randomized design was used by different clove essential oil including P10, 0% clov...

Using urban household-level survey data from 1992 to 1998, we provide estimates of final demand for edible vegetable oils and animal fats in three regions of China based on the LinQuad incomplete demand system. For each region, the demand for the major “staple” oil is price inelastic. The demand for “condiment” or flavoring oils is more price responsive. All edible oils and fats have positive i...

Nowadays, food contamination by mineral oil (MO) is a very important issue and its presence in edible oils is widely documented. Mineral oils are hydrocarbons mixture of petrochemical origin containing mainly two families of compounds, namely mineral oil saturated hydrocarbons (MOSH) and mineral oil aromatic hydrocarbons (MOAH). The most used approach for mineral oil analysis is liquid chromato...

Energy conservation is important for most of the developing countries, including rest of the world. The rapid depletion in world petroleum reserves and uncertainty in petroleum supply due to political and economical reasons, as well as the sharp escalations in the petroleum prices have stimulated the search for alternatives to petroleum fuels. The situation is very grave in developing countries...

Recently, sesame oil is highly appreciated by consumers due to its sensory qualities, antioxidants activity and nutritional benefits, despite its high price. Also, the detection and quantification of adulteration both are problem with increasing importance in the consumer’s health and food industry. The goal of this study was to use Fourier transform mid-infrared (FT-MIR) spectroscopy coupled w...
