Until the 1990s the major edible oil consumed in Tamil Nadu state was peanut and sesame oil. The technological, economic and policy changes thereafter induced dynamism in consumer demand for food, including edible oils. In this study, the household demand for individual edible oils based on present consumption was assessed and forecasted for 2015 and 2020 for Tamil Nadu. Due to constraints in the secondary data published by National Sample Survey Organisation (NSSO), the primary data was used. The Almost Ideal Demand System (AIDS) model was employed to estimate the income (expenditure) elasticities and in turn used to project the demand for edible oils and associated products like ghee and butter. The overall edible oil demand is expected to grow at 7.0% per annum in Tamil Nadu, with the highest growth of sunflower oil (8.7%) followed by other oils (7.8%), sesame oil (6.6%), peanut oil (6.6%) and palm oil (3.1%). The demand for total edible oil in rural Tamil Nadu increases from 3.14 lakh tonnes (2009-10) to 5.3 lakh tonnes (2020), whereas, in urban areas, it increases from 3.24 lakh tonnes to 5.45 lakh tonnes. The non-traditional oil like sunflower oil and other oils (soybean, corn, rice bran, palm oil) has made inroads in the consumption basket and will continue to dominate in the future. Hence, concerted efforts like increasing seed replacement rate, increasing the intensity of adoption of improved technology and appropriate price policy are required to increase productivity of non-traditional crops besides promoting traditional crops (peanut and sesame) to meet the growing edible oil demand in the state.

Food is a basic part of our existence and nourishes the body. The Indian consumer underwent a remarkable transformation in their consumption pattern. Food consumption and expenditure on different commodities is an important area of research for economists. The NSSO data (68th round) was used to derive different demand elasticity for different food groups in Tamil Nadu. The income elasticity derived from the Quadratic Almost Ideal Demand System model revealed that the food group, milk and vegetables are necessary goods in rural households but luxury goods in urban households. The meat was necessary good in urban households but luxury goods in rural households. The uncompensated own price elasticity showed the demand reacted elastically to own price changes for meat, edible oils, and nuts in rural households, milk, egg, vegetables, fruits, nuts and oil in urban households. The uncompensated cross-price elasticity showed milk and beverages were substitutes in both rural and urban households. Similarly, meat and egg in rural, milk and egg, fruits and nuts in urban households were substitutes. The compensated own price elasticity showed nuts and oil in rural and urban households, meat in rural and milk, egg, vegetables and fruits in urban households, were elastic to the price change. The compensated cross-price elasticity showed, fruits, and nuts, egg and meat, meat and fish, appeared to be moderately strong substitutes, cereals and vegetables were complements in rural households, whereas vegetables and edible oils, fruits and vegetables, were substitutes, the commodity group’s fruits and nuts, milk, and egg, were complements in urban households of Tamil Nadu. The study recommended policies such as appropriate technology development to enhance the productivity of oilseeds and meticulous planning of the quantum of edible oil to be imported and rationalization of distribution of edible oils through Public Distribution System, exclusively to the households living under the poverty line to meet the growing demand for edible oil.

Fatty acid analysis of the five types of locally consumed edible oils (n = 22) was carried out using a Gas Chromatograph (G.C) equipped with a Flame Ionization Detector (FID) and stainless steel packed column. The results showed that sunflower oil contained the highest percentage of long chain mono and polyunsaturated fatty acids (91.49 ± 1.91 %) compared to soybean oil (81.14 ± 1.49 %), mustard oil (86.80 ± 3.07 %), palm oil (53.30 ± 0.36 %) and coconut oil (7.12 ± 0.51 %). Two varieties of mustard oil, low erucic (= 5 %, n=3) and high erucic acid ( >14 %, n=2) and two varieties of sunflower oil, high linoleic-low oleic (61-66 % & 22-27 %, n=2) and low linoleic- high oleic (29-38 % and 53-63 %, n =3) were found. Sunflower oil with the highest percentage of mono and polyunsaturated fatty acids especially the high linoleic- low oleic variety appeared to be superior and most suitable edible oil for mass consumption.

Since rice bran oil (RBO) is well-known by consumer and more expensive than other oils, some RBO is adulterated with other cheap oils, such as cottonseed oil (CO), palm oil (PO), sunflower oil (SFO) and soybean oil (SO). The types and content of FAs in RBO changes great after adulterated, this will seriously affect the quality of the rice and the people health. In this study, GC was used to detect the change of fatty acids (FAs) after adulterated with those inferior oils. The analysis will provide a reference for the RBO adulteration problem.

Deep frying is the process of immersing food in hot oil at a temperature of approximately 180°C. During deep frying, different chemical reactions are taking place, resulting in changes in the physicochemical properties of the frying oil, eventually leading to harmful health effects on the consumers. Nevertheless, based on economic feasibility, both the domestic and industrial levels tend to repeatedly use edible oils for deep frying. Thus, the current study aimed to evaluate physicochemical and nutritional parameters of commercially available coconut oil, palm oil and sunflower oil and to investigate the effect of repeated deep frying for the physicochemical and nutritional parameters of the studied oil samples. Thereby, the optimum number of frying cycles for each type of oil was also investigated. In order to achieve that, using coconut, palm and sunflower oils, potato and fish were fried separately for five repeated frying cycles. As per the results, regardless of the frying material, the relative density, colour, peroxide value, free fatty acid value of coconut oil, palm oil, and sunflower oil were increased significantly with increase the number of frying cycles whereas the smoke point and moisture content was found to be significantly decreased. In contrast, the number of cycles suitable for repeated frying is varying upon the frying material. Accordingly, coconut oil has proven to be used for three frying cycles of potato and five frying cycles of fish: palm oil for one frying of potato and two fryings of fish without adversely altering their physicochemical and nutritional properties. Conferring to the obtained results, the use of unsaturated oil like sunflower oil on repeated frying is not recommended.

The present study focuses potentiality of biodiesel production in Bangladesh from non-edible oil. The increasing demands of energy are consumed by using fossil fuels which are non-renewable and will be depleted within 150 years from now if this growth rate stays but if this rate increases further the depleting time will decrease from the estimated one. Because of low reservation of crude oil, Bangladesh has to import oils from other countries, these costs a lot. About 95% of these demands can be meted through biodiesel. Biodiesel prepared from both edible and non-edible oils. After meeting demands of edible oil of the country it is impossible to produce biodiesel from edible oils. But it is possible to meet the biodiesel demand of the country almost 100% through non-edible oil derived biodiesel. Arable lands of Bangladesh can’t be used for the growing purposes of non-edible oil seeds, but if rail and road sides are used there is no need for extra lands. After surveying lands for this purpose it seems that Bangladesh can get a total amount of 47750 Km of road and rail side areas for the cultivation of non-edible seeds. Among these forest seeds Nageswar, Pitraj, Sultana champa Ponyal, Rata, Oil palm, Chaulmoogra, Bakul, Kusum, jaina have sufficient oil content along with plenty of growth in Bangladesh. Cultivating these seeds 1100000 tones of biodiesel can be produced on the basis of their oil content and yield. Which decreases the amount of imported crude oil as well as meets the oil demand of the country, thus Bangladesh can be able to save about $6 billion per year means a great economic savings that can be used for the development of the country.

Nir Reflectance Spectroscopy

The visible and near-infrared (Vis-NIR) reflectance spectroscopy was utilized for the rapid and nondestructive discrimination of edible oil adulteration. In total, 110 samples of sesame oil and rapeseed oil adulterated with soybean oil in different levels were produced to obtain the reflectance spectra of 350–2500 nm. A set of multivariant methods was applied to identify adulteration types and adulteration rates. In the qualitative analysis of adulteration type, the support vector machine (SVM) method yielded high overall accuracy with multiple spectra pretreatments. In the quantitative analysis of adulteration rate, the random forest (RF) combined with multivariate scattering correction (MSC) achieved the highest identification accuracy of adulteration rate with the full wavelengths of Vis-NIR spectra. The effective wavelengths of the Vis-NIR spectra were screened to improve the robustness of the multivariant methods. The analysis results suggested that the competitive adaptive reweighted sampling (CARS) was helpful for removing the redundant information from the spectral data and improving the prediction accuracy. The PLSR + MSC + CARS model achieved the best prediction performance in the two adulteration cases of sesame oil and rapeseed oil. The coefficient of determination (RPcv2) and the root mean square error (RMSEPcv) of the prediction set were 0.99656 and 0.01832 in sesame oil adulterated with soybean oil, and the RPcv2 and RMSEPcv were 0.99675 and 0.01685 in rapeseed oil adulterated with soybean oil, respectively. The Vis-NIR reflectance spectroscopy with the assistance of multivariant analysis can effectively discriminate the different adulteration rates of edible oils.

Abstract Objective: Cooking oils (edible oils) are vegetable oils which are extensively used for cooking in India. These edible oils are rich in triglycerides, sterol, tocoferol, carotenes and pigments. Upon frying, edible oils gives rise to formation of free radicals and other harmful agents. The degraded products of oils generated while cooking produce unfavorable effects. The present study was designed to evaluate the effects of reused edible oils (sunflower oil and palm oil) on vital organs of experimental animals. Materials and Methods: Wistar rats were fed fresh and reused edible oils - sunflower oil and palm oil (15 gm oil/100gm of feed consumed) and control group received normal food and water for a period of 8 weeks. The parameters studied include changes in physicochemical properties of reused oils, change in body weight of animals, plasma lipid profile, biochemical parameters and histopathological examination. Results: The result showed the change in physicochemical characteristics of reused oils. The animals fed with fresh and reused palm oil significant increase the body weight while reused sunflower oil fed group showed decrease significantly. The biochemical parameters, SGPT (serum glutamate–pyruvate transaminase), SGOT (serum glutamate- oxaloacetate transaminase), and ALP (alkaline phoshphatase) were increased in reused oils fed groups. The histopathological study showed the change in size of liver, heart, kidney and testes cells in reused oil groups. Conclusions: From the present study, it can be concluded that reused sunflower oil and palm oil, can be toxic and can cause considerable damage to the vital organs of the experimental animals.

Background: Cerebrovascular diseases (CBVDs) and diabetes mellitus (DM) are interrelated and cumbersome global health burdens. However, the relationship between edible oils consumption and mortality burdens of CBVDs and DM has not yet been evaluated. This review aims to explore correlations between per capita mortality burdens of CBVDs and DM, as well as food consumption of palm or soya oils in 11 randomly selected countries in 2005, 2010, and 2016. Methods: After obtaining data on food consumption of palm and soya oils and mortality burdens of CBVDs and DM, correlations between the consumption of oils and mortality burdens of diseases were explored. Results: There was a positive correlation between the consumption of soya oil with the mortality burden of CBVDs in Australia, Switzerland, and Indonesia, as well as the mortality burden of DM in the USA. The consumption of palm oil had a positive correlation with the mortality burden of DM in Jordan only. Conclusions: Food consumption of soya oil in several countries possibly contributes to the mortality burden of CBVDs or DM more than food consumption of palm oil, which could be a possible risk factor in the mortality burdens of CBVDs and DM.
