Module 9-oil seed species (canola) Flashcards
what is canola production like in Canada
Canola is Canada’s largest oilseed crop
what acids are found in canola oil
Canola is a low erucic acid rapeseed, containing less than 2 percent erucic acid in contrast to the 45 percent erucic acid in rapeseed from which canola was developed
what is erucic acid
Erucic acid is a monounsaturated fatty acid that imparts a bitter taste to the rapeseed oil and meal and, at one time, was believed to increase risk of heart disease in humans
what are modern cultivators low in
Modern cultivars are also low in thioglucosides (glucosinolates).
what is thioglucosides
Thioglucosides are toxic anti-nutritional sulphur compounds
what are the physical characteristics of conola seed
The canola seed is small, round and black, yellow-brown or yellow
how much oil is contained in a canola seed
The seed contains 45 percent oil
what was a recent global production of canola oil
Global production of canola oil was just under seventy million tonnes in 2020
how many tones of canola was produced in the worlds larges producer in recent years
the world’s largest producer, Canada, harvested eighteen million tonnes in 2020
can canola be dehulled prior to oil extraction
The small canola seed cannot be effectively dehulled prior to oil extraction
since The small canola seed cannot be effectively dehulled prior to oil extraction what does this mean
the meal produced from the hulls is a by-product of the extraction process
what is the nutritional composition of canola meal
Canola meal is high in fibre and low in protein
although the protein of canola meal is low why is it still good quality protein
the protein is high quality comprised of a good balance of nutritionally essential amino acids
what cost more canola meal or soybean meal
Canola meal is lower in price than soybean meal
what is the thought of canola meal when fed to animals
canola meal has a lower inclusion rate in feeds for beef, swine and poultry
why is canola meal not a fan favourite for animal feeds
The meal contains glucosinolates and other negative factors that affect nutritional value, colour and palatability and limit inclusion rate in feed
is canola meal or protein used for human consumption
Canola meal or protein is not currently used in the production of foodstuffs for human consumption.
what is canola oil used for
Canola oil is considered to be a general purpose oil used in salads, as a frying oil, a food ingredient, in the production of margarines and shortenings and in biodiesel production
is canola oil considered healthy? why or why not
The low saturated fatty acid content in canola oil supports its designation as a “healthy” vegetable oil
what can happen if you refrigerate canola oil
Refrigeration can cause some precipitation of fat because of the oleic acid content, similar to that found in olive oil
what much be done to liquid canola oil for oxidation instability and what is it due to
Liquid canola oil must be brush hydrogrenated to compensate for oxidative instability due to linolenic acid content.
who has joined forced to work on canola and whats there goal
Plant breeders and genetic engineers have joined forces to continue the evolution of canola into a higher quality oilseed
what new canola seeds are being produced
New fatty acid profiles, including lines high in saturates, very high in oleic acid or low in linolenic acid, have been developed, and new lower fibre, clear-seed-coated (so-called “yellow-seeded”) varieties are soon to be commercialized. High erucic acid varieties are currently in production. High erucic acid rapeseed (HEAR) is grown under contract to supply demand for erucic acid used in the production of lubricants and plastics. In addition, canola-quality Oriental mustard (Brassica juncea) is under development
what will the new varieties of canola help contribute to
This will make new, higher yielding varieties of canola with enhanced drought, heat, and disease resistance available.
