Vegetable fats and oils

alleviate the oxidative damage leading to improvements in physiological attributes for the plant growth under salinity. Key words: Canola, inorganic nutrients, Nitrose oxide, proline, salinity, Zea mays Introduction Vegetable oils are, and have been an important component of the human diet for a long time. Nowadays, the four major vegetable-oil producing crops (oil-palm, soybean, rapeseed and sunflower, respectively) cover about 270 million hectares, with a production of 170 million tons, and accounting for approximately 75% of the world total production (FAO, 2013). In general, Egypt 's production of vegetable oils, covers only a small portion of its current demand. According to Hassan and Shafique (2011), Egypt’s self-sufficiency of vegetable oil declined from 95 % in early 1960’s, to less than 30 % in 2004, leading to increase the importation of processed vegetable oil and semi-processed oil-seeds. In 2011, Egypt spent about 1.875 billion US dollars on importation of vegetable oils combined (FAOSTAT: Egypt. 2011). The United States Department of Agriculture, division of Foreign Agriculture Service (USDA-FAS), reported in 2013-2014 that Egypt’s total oilseeds planted area only covers 3-5% of Egypt’s total edible oil consumption. Expanding into edible-vegetable oil production in Egypt is limited due to limitation of agricultural land and water supplies. Out of about 3.7 million hectares available for food production, it is estimated that 3.2 million hectares are dedicated…

This guide will explain some of the most common oils available and their proper uses. The most important qualities of oils to consider include smoke points, saturated vs. unsaturated, and flavor, all of which will be explored in this article. Vegetable Oil This is one of the most common oils used in kitchen. Made from a blend of oils refined from vegetables, seeds, and nuts, vegetable oil is inexpensive and useful for many different types of cooking. This oil has a mild flavor which is ideal…

During this lab, I compared the properties of both regular and light margarine, before and after melting. First, we took both of the margarine samples and put them in a hot water bath to melt them. This separated out the components within them- making it easy to measure their percentage value. I found the regular margarine to be made up of 14.5% solids, 64.2% oils, and 21.3% water. Next, I used the same method as before, and found the percentage of each component of the light margarine to…

been studied that saturated fats increase cholesterol. Mono-unsaturated (one carbon double-double bond) and polyunsaturated (more than one carbon double-double bond) found primarily in vegetable oils, tend to lower cholesterol and therefore better for your health. Higher cholesterol elevates the chances of getting coronary heart disease. Back in the 1950’s, it was discovered that animal fats could be substituted with vegetable oils in the substance we know as margarine. This meant that…

looking at commercial alternatives to trans-fat use in processed foods, there are four factors to consider. These factors include: performance, availability, economics, and safety. Currently, there are many alternatives under development, such as: modified hydrogenation, genetically modified seeds, interesterification, fractionation and blending, butter and animal fat, natural saturated oils, natural unsaturated oils, and other fat substitutes. Partial hydrogenation of vegetable oils is…

Lipids have a significant energy role, but also a fundamental role in the composition of the membranes of cells, nuclei, and nervous tissue. Focus on these fats and the foods that contain them. Edible fats Dietary fats should be present in the daily diet at 2-3 g / kg bodyweight per day (30-35% of total energy intake). But this rate is very easily exceeded because lipids are not always visible. The hidden fats are those that are contained in foods that do not appear fatty: meat, cold meats,…

"Our study shows that a Mediterranean diet rich in vegetable fats such as olive oil and nuts had little effect on bodyweight or waist circumference compared with people on a low-fat diet. The Mediterranean diet has well-known health benefits and includes healthy fats such as vegetable oils, fish and nuts." High-fat Mediterranean diet does not cause weight gain, study finds Researchers found that people whose diets were rich in olive oil and nuts lost more weight than those on low-fat regime.…

and many other things. Since I will be talking about these things, I will be giving examples of each subtopic. The food pyramid is made up of 5 groups. The five groups are grains, vegetables, fruits, dairy, and protein. Common vegetables such as, carrots, cabbage, lettuce, green beans, peas, broccoli, cucumber, and kale all gives the body vitamins and minerals to help the body function and to keep…

engines that is made from renewable biological sources like vegetable oils, animal fats, and microalgae. Since its main feedstock is a vegetable oil or animal fat, biodiesel is generally considered to be renewable. There are four primary ways known to make biodiesel – (1) direct use and blending, (2) microemulsions, (3) thermal cracking and (4) transesterification. Although the main use is the transesterification of vegetable oils and animal fats, all four ways are going to be discussed through…

Butter v/s Margarine Keyonn Finch Daymar College I use butter in almost everything I cook like fish, eggs, cakes, cookies, pork chops without flower etc. It’s high in fat and I’m the last person to be eaten cause of my high blood pressure. In our history books it says butter was founded 4,500 years ago back in ancient time when everything was done by hand. Butter can be salted or unsalted and it spreads on toast so smooth. My mom and I fuss all the time when cooking eggs…
