Oilseeds and edible oils are two of the most sensitive essential commodities. Oilseeds are important sources of edible oils of nutritional, industrial, and pharmaceutical importance. Groundnut, mustard/rapeseed, sesame, safflower, linseed, niger seed, castor are the major traditionally cultivated oilseeds. Soybean and sunflower have gained high importance in recent years, while coconut is most ...

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...

Edible oil seed crops, such as rapeseed, sunflower, soyabean and safflower and non-edible seed oil plantation crops Jatropha and Pongamia have proved to be internationally viable commercial sources of vegetable oils for biodiesel production. Considering the paucity of edible oils and unsustainability of arable land under perennial plantation of Jatropha and Pongamia in countries such as India, ...

The effect of repeated heating process on edible oils namely, sesame oil (SO), sunflower oil (SFO) and palm oil (PO) with and without antioxidant, tertiary butyl hydroquinone (TBHQ) have been evaluated using ultrasonic velocity. The changes in physico-chemical properties of edible oils has been studied during repeated heating at 180 ± 5oC for 4 hrs/day and for 4 days. The effect of antioxidant,...

Adulteration of edible oils has attracted attention from more researchers and consumers in recent years. Complex multispecies adulteration is a commonly used strategy to mask the traditional adulteration detection methods. Most of the researchers were only concerned about single targeted adulterants, however, it was difficult to identify complex multispecies adulteration or untargeted adulteran...

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...

Edible oils and fats are among the most abundant cooking ingredients in the world, and are an important part of a healthy balanced diet, especially if they are high in omega-6 and omega-3 polyunsaturated fatty acids. Rather than just the total fatty acid compositions, the analysis of individual lipid species within these oils and fats have become increasingly important. Within the past decade s...

Biodiesel is an alternative source of energy in diesel engines in its neat form or as a blend with conventional diesel fuel. The raw feedstock costs represent a lot of the overall biodiesel production cost. Therefore, the employment of waste oils or non-edible oils (which do not compete with edible oils) as feedstock for biodiesel production are presented as the best alternative. However, the p...

A method for determination of palmitic acid in edible oils by the near-infrared spectroscopy was addressed in this paper. 56 samples were collected in the experiment. In terms of concentration content gradient method, 44 samples were selected for modeling set and 12 for testing set. This paper described the utilization of PLS for establishing a quantitative analysis model for predicting the con...
