Rapeseed is the worlds number two oil seed crop ranking behind soybeans and a head of cotton seed, peanuts and sunflower seeds. The oil from it has the best fatty acid composition of all vegetable oils.
Canola is genetically improved rapeseed, has low composition of erucic acid and glucosinolates and hence called 'double-low'. In global production rapeseed and canola now rank second with 45 million metric tons produced or 15%of world oil seed production of 286.2 million tons.
1. Rapeseed meal for protein production; The protein from the meal can be solubilized and precipitated out by using different mechanism of protein precipitation .Table salt and cold water can be used in this process The protein isolate has an excellent balance of amino acids and useful functional properties for applications in both food and non-food sectors. More on this
2. Paper: Rapeseed meal proteins isolates showed good interaction with paper fibers .The effect of rapeseed protein was investigated on the mechanical properties, stiffness and strength of recycled paper .Therefore they could be used to improve mechanical properties of recycled paper.
3. As personal care ingredients .As a plant ingredient in cosmetic or other body care applications in which animal based ingredients might be undesirable’s 20 % and 40% ethanol-water mixture was used to test the raw material solubility which makes their way in cosmetics products possible."...It whips and foams like an egg white and that means it functions as binding ingredient ''.This is big benefit when one look at the package food industry.
4. Rapeseed meal as fertilizer; the concern is competitive market with very low price .The meal has to have slightly higher value than traditional fertilizer .Therefore, there is no used for specific properties of the meal.
Field experiments under controlled conditions show fast mineralization nitrogen contained in the meal .The results caused be too fast growth before winter in the case of early seeding and an important risk of leaching during winter.
5. Rapeseed meal as combustion martial; the calorific value of or power of the meal is roughly equal to the ones of anthracite and charcoal; 17,500kJ/kgas compared to 20,000kJ/kgof coal and anthracite. The auto inflammation point of rapeseed meal is relatively of high value (nearly 700 degree centigrade) The main thermal characteristics of the meal allows its utilization as material for combustion .As content is relatively low and its calorific value is approximately equivalent to the ones of charcoal.
6. Rapeseed meal for bio gas production; Rapeseed meal can be fermented in a biogas plant to produce biogas. Co-fermentation with liquid manure is used yielding a gas converted to heat and power by small combined heat and power plant .Certain studies show a gas yield of 350lit/kg meal.
The above figure shows the rest of the applications. These applications could be studied separately as investigatory project ideas on rapeseed meal.
Investigating the feasibility of establish a Oil Seed Rape grain Biorefinery in Scotland UK. The handling capaicity would be 100,000 MT of grain per year. We own a patented Bio Fuel methodology that makes use of Bio Ethyl Acetate and this could form part of the oil extraction/expelling process. Yes, I think protein extraction methodology applied to RMC could have major economic values for multiple sectors.
ReplyDeleteThanks for the comment. Your suggestion of final project idea is practical.
Deletethanks you sir.please new chemical engg simple project idea given to me
