CANOLA OILGood for Every Body!

Introduction

Canola oil is made from canola seed, Canola oil is extracted from tiny canola, which is massively grown in North America especially in regions of Western Canada . Canola was bred naturally form its parent rapeseed in the early 1970. However, the canola is not rapeseed due to the fact that their nutritional profiles are totally different. Canola oil has been used in cooking world widely because it contains lowest level of saturated fatty acids, is high in monounsaturated fatty acids, which have been shown to reduce blood cholesterol levels, and has moderate levels of essential polyunsaturated fatty acids; Moreover, canola oil is cholesterol-free. there are many scientific report shown that Canola oil is good for health.

How to Produce the Canola Oil

The production of Canola oil involves mechanical pressing and extraction process, and further processing to remove impurities.

Cleaning:


Graded seed is cleaned by many different way, such as ,air aspiration , indent cylinder cleaning, sieve screening and a combination of theses cleaning in order to get rid of foreign material.

Preconditioning:


Seed is preconditioned using mild heat treatment, and moisture is then adjusted to improve subsequent oil extraction.

Processing:


Canola seed is next crushed and flaked and then heated slightly. These processes help to maximize oil recovery. The canola flakes are then "prepressed" in screw presses or expellers to reduce the oil content from about 42% in the seed.

Canola oil extraction:


Press cake which results from seed processing is next subjected to one of two types of oil extraction to remove much of the remaining oil. Oil may be extracted using either hexane ("solvent") extraction or by "cold-pressing" (also referred to as "expeller pressing").

Oil refining:


The extracted oil calls crude oil because it contains various compounds that must be eliminate to make sure a product with good stability. Different ways are used to these by-products including water precipitation or organic acids in combination with water. After water precipitation and/ or organic acid processing, the oil still contain color compounds which must removed to attract the consumer. Color compounds are removed by bleaching. Oil is bleached with the natural, diatomaceous clay instead of harsh chemicals.Deodorization is the final step in the refining of all vegetable oils, including canola. Deodorization involves the use of the steam distillation to remove any residual compounds.










What is Canola?

Canola is not a natural plan since Canola was developed through traditional plant breeding from rapessed in 1970s. Plant scien-tists used traditional plant breeding methods to eliminate the unhealthy nutrition of Erucic acid and Glucosinolates in rapeseed. The name of Canola took Can from Canada because it was invented by Canadian and Ola from oil low acid. In other words, Canola is a coined word. There is an extremely strict regulation to define the name of Canola. The oil made of Canola seeds must be less than two percent erucic acid and less than 30 umoles glucosinolate. Otherwise it can’t be called Canola oil.








Where is Canola Grown?

Canola is grown primarily in three Prairie Provinces of Canada , Alberta , Saskatchewan , and Manitoba . But it is planted in Ontario and the Pacific Northwest, north central and south eastern United States as well. Canada is the biggest single producer in the world. Nevertheless, the EU member countries combined grow more Canola than Canada . Rapeseed grown in china is more than Canada ’s canola production. Canada's canola industry contritubed $13.8 billions to Canadian economy. More than 52,000 Canadian farmers grow canola – largely as full-time farmers and in family farm businesses. They depend on canola to generate between one third and one half of their revenues

Why Scientists Strongly Recommend to use Canola Oil Instead of Other Cooking Oil?

Canola’s appearance is almost the same as Rapeseed; however, the ingredient is extremely different between each other. Canola is low in saturated fat, a source of omega-6 fat, high in omega-3 fat, high in monounsaturated fat and cholesterol and trans fat free. In comparison to all the cooking oil in the supermarket, Canola has the lowest level of saturated fat (7 percent), it is relatively high in monounsaturated fat (61 percent), and canola oil has a moderate level of polyunsaturated fat (32percent). After traditional plant breeding methods, the canola becomes a healthy food for us; furthermore, the U.S Food and Drug administration authorized, in October 2006, a qualified health claim for canola oil base on its high percentage of unsaturated fats. The claim stated: “limited and not conclusive scientific evidence suggests that eating about one and a half tablespoons (19 grams) of canola oil daily may reduce the risk of coronary heart disease due to the unsaturated fat content in canola oil.

Argument with Canola

Canola is a genetically invented plant developed from the Rapeseed plant; therefore, it is not natural. Rapeseed oil is poisonous to living things and is an excellent insect repellent. In England and Europe between 1986 and 1991, rape oil caused a disease called Mad Cow disease when animals were fed with rape oil; consequently, Rapeseed is not healthy food for living things. So far, many scientists still have argument about that canola is genetic plant and was developed from poisonous rapeseed although Canola’s ingredient is extremely good for human.

Conclusion

From what have been described on above, the canola is healthy oil for our human consumption and it is one of largest business in Canada. In the future the Canola oil will be developed to enhance nutritional qualities, safety for mankind and the canola oil industry will be booming.
