Nutritional Facts of Rapeseed

There are two main types of rapeseed oil: culinary and industrial. The culinary version,also known as canola oil, is used in the kitchen for cooking. Industrial rapeseed oil is mostly used in the chemical and automotive industries.:-

Is Rapeseed Oil Healthy?

Rapeseed oil is widely used around the world. It's famous for its affordability and versatility as a cooking oil and is commonly found in salad dressings, fried foods, and baked goods.Rapeseed oil is naturally low in saturated fat and high in unsaturated fat, which is excellent for your health.It’s an excellent source of vitamin E — a strong antioxidant, which can support eye and skin health.Rapeseed oil is also a great source of an omega-3 fat known as alpha-linolenic acid, which provides numerous heart health benefits like lower blood pressure and a decreased likelihood of heart attack.

Possible Downsides of Rapeseed Oil

Genetically modified. Most rapeseed oil sold in grocery stores is genetically modified. Growers genetically modify plants to produce higher yields and more affordable products.There is some concern about genetically modified foods and their effect on antibiotic resistance, allergies, and cancer. However, most research does suggest that genetically modified products are generally safe.If you want to avoid genetically modified foods, buy rapeseed oil that’s labeled as GMO-free or certified organic by the United States Department of Agriculture (USDA).

Benefits of Rapeseed Oil

Versatility. You can use it for roasting, frying, deep-fat frying, baking, marinades, dipping, drizzling, and sauces.High cooking temperature. Rapeseed oil has a high smoke point, which means it won't burn until about 400 degrees F. That makes it a good choice for frying mushrooms or roasting vegetables.etc

Transesterification of rapeseed oil

Synthesis of fatty acid methyl esters from rapeseed oil was carried out in a fixed bed continuous flow reactor at 60 °C with 1 g of catalyst pellets, a molar methanol to oil (triglyceride) ratio of 40 and at liquid hourly space velocity of 6.5 h-1.

Liquid Biofuels for Power Generation/Combined Heat and Power

Diesel and heavy fuel oil can be replaced with liquid biomass fuels like rapeseed oil, palm oil, tallow, and tall oil. Palm oil has become very sensitive from a public relations point of view due to all the media coverage around palm plantations and their negative impact on biodiversity, orangutans, etc.

Biobased Oils

Biobased lubricants are primarily crop based including vegetable oil, rapeseed oil, sunflower oil, coconut oil, and soybean oil. These are all considered biodegradable fluids. Biobased lubricants, in particular crop-based grease products, can have poor low-temperature performance and degradation at high operating temperatures, so that needs to be considered in drive machinery applications.

Conclusion

NaOH/bentonite was investigated as a solid alkaline catalyst for transesterification of rapeseed oil. The catalyst showed high catalytic activity and 99% FAME yield was achieved. The optimum parametric conditions were found to be 1:20 catalyst ratio, 6 wt.% of catalyst amount, and 4 hours reaction time. Numerical optimization predicted 96.9% FAME yield.

Sterilization and Radiation Resistance

This “green stabilizer” is a rapeseed oil-based amine oxide with a molecular weight of 580–610 and melting point of 85–105°C. With long alkyl side chains that make it compatible with polyolefins, it is said to resist color development under UV and gamma radiation, with no problems with hydrolytic stability.

Biodiesel from plant oils

Several countries produce biodiesel from rapeseed oil, palm oil, and soybean oil. In the United States, biodiesel is produced mostly from soybean oil. Other vegetable oils and animal fats such as canola, camelina, and jatropha constitute a small fraction of biodiesel feedstock. Soybean seeds yield about 18% oil and the remaining meal, which is the primary product of soybean and sold as a highly nutritious animal feedstuff. Because of the high yield of the meal, this coproduct may provide better monetary returns per ton of seed than the oil used in biofuel production.

Fed-batch into CSTR Experiment (Fitting and model evaluation dataset)

The reactor was charged with 1980 g of rapeseed oil and 0.525 equivalents (eq.) methanol based on the oil in the reactor. One equivalent corresponds to the stoichiometric amount of alcohol needed to convert all fatty acid residues in the oil to biodiesel (i.e. 1 mol oil : 3 mol alcohol). When the reaction mixture reached the reaction temperature, the reaction was then started as a fed-batch operation.
