“…Most of the changes described here are explained by the unique FA profile that brassicas have. In this study, the FA profile from diets (Table 1) showed that brassicas have high contents of FA with >20 carbons, which is in agreement with previous research on different brassica species (Sharafi et al, 2015).…”

In humid temperate regions, forage turnip (Brassica rapa ssp. rapa) and forage rape (Brassica napus ssp. biennis) are common fodder crops used for dairy cattle during the summer season. However, there is little scientific information regarding the use of brassicas and their effect on the fatty acid (FA) profile in blood, milk, and milk products. The aim of this study was to evaluate the effect of forage brassica supplementation in dairy cows on the FA profile of blood plasma, milk, and cheese, and on the sensory characteristics of Chanco and Ricotta cheeses. Twelve multiparous dairy cows (Holstein Friesian) were housed and submitted to a 3 × 3 replicated (n = 3) Latin square design with 3 treatments (control, turnip, or rape) in 3 periods of 21 d each (14 d of diet adaptation and 7 d of measurements). The control diet consisted of 16.20 kg of grass silage (Lolium perenne), 2.25 kg of soybean bran, and 2.25 kg of commercial concentrate, all on a dry matter (DM) basis. In the treatments with forage brassicas, 24.15% of the total DM was replaced by turnip or rape; thus, they consisted of 12.25 kg of silage, 2.25 kg of soybean bran, 1.2 kg of concentrate, and 5 kg of turnip or rape (DM basis). A principal components analysis was performed on the results of the cheese sensory evaluation. Supplementation with turnip or rape modified the profile of FA in blood plasma and milk, increasing the saturated fraction, mainly short-and medium-chain FA, and decreasing the mono-and polyunsaturated FA. In the sensory evaluation, diet did not affect any of the 18 attributes evaluated. However, in the principal components analysis, cheeses made with milk from animals fed turnip and rape were differentiated by increased odor, flavor, spiciness, bitterness, and acidity. Overall, brassicas can be used as an alternative forage source with no negative effects on sensory characteristics of cheeses.

“…). Seeds such as cruciferous mustard ( Brassica juncea ), radish ( Raphanus sativus ), Chinese cabbage ( Brassica campestris ), white flax ( Camelina sativa ), rapeseed ( Brassica napus ), meadowfoam ( Limnanthes alba ), rocket grass ( Eruca sativa ), and nasturtium ( Nastrutium officinale ) contain large amounts of C 20 or longer chain unsaturated fatty acids (Table ). Mustard seed oil contains more than 40% erucic acid (C22:1, ω ‐9), which can produce 1‐decene and 13‐tetradecenoic acid.…”

“…Unlike Canola, its ancestral cauliflower and turnip seed oil contains more than 40% erucic acid. Black mustard ( Brassica nigra ), Brassica juncea (a hybrid of black mustard and turnip), and Brassica carinata (a hybrid of black mustard and cauliflower) also contain a large amount of erucic acid . On the other hand, breeding studies were carried out to increase the content of erucic acid as the value for industrial applications, such as the raw materials for polymer production, increased, and a 72% lecithin variety was developed .…”

Bio‐oil contains plant, animal, fish, and micro‐algae oil, and more than 200 million tons are produced annually. However, many edible and non‐edible bio‐oils are still under development, and their value and feasibility have yet to be determined. The vast majority of bio‐oils produced in the world have a very high unsaturated fatty acid content (70–98%), which could be used as a renewable, eco‐friendly alternative to petroleum. Hydrolysis (or transesterification) with ethylene metathesis technology converts unsaturated fatty acids to C4–C30 oil fragments. These oil fragments are a sustainable chemical technology used in chemical industry platform technology and carbon dioxide abatement green chemical technology, and as a petrochemical substitute. These platform chemicals also have their own market but are used as raw materials for other products (polymers, surfactants, synthetic lubricants, plasticizers, other specialty chemicals, general purpose chemicals, biofuels, etc.). The biodegradability and biocompatibility of the polymeric materials made from the oil mean that it is also possible to develop diverse functional products with high added value such as toothpaste, dandruff treatment shampoo, and melanin pigment removal cosmetics, medical and shape memory polymer materials. According to the cradle‐to‐gate analysis for environmental impact and economics, the total carbon dioxide emission reduction per ton of soybean oil was estimated to be 1.5 kg kg−1 products. Moreover, the metathesis of soybean oil ($680/ton) with additional raw materials ($237.4) will generate a value that is 7.5 times higher at $6857. Due to the biodegradability and biocompatibility of the products made from bio‐oils, it is expected that various functional products with high added value will be developed and that industrial applicability will be greatly expanded in the near future. In addition, for the development of various derivatives, fusion and cooperative research in chemical fields such as catalytic engineering, organic chemistry, polymer chemistry, maintenance chemistry, and reaction engineering are essential. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd

“…In general, rapeseed oil contains ∼7% saturated fatty acids (including palmitic acid and stearic acid), and high amounts of monounsaturated fatty acids with a significant fraction of oleic acid (∼61%). It also contains an important amount of polyunsaturated fatty acids with significant fraction of linoleic acid (∼11%) and a-linolenic acid (∼21%) (Sharafi et al, 2015).…”

Genetic variability is a prerequisite for any plant breeding program, and mutagenesis is a proven way of creating new variation within a crop germplasm. Novel genetic variability in rapeseed was induced by gamma rays, Ethyl Methane Sulphonate (EMS) and combined mutagen treatment, using various doses and concentrations. The objective was to evaluate and compare the obtained M 2 mutants for important quantitative traits in two contrasted environments. Data on phenological, morphological and agronomic parameters were recorded. A large variability was observed and mutagenic treatments had a significant effect on all traits studied. Compared to control plants, mutant genotypes derived from seeds treated with low EMS concentrations during moderate time were earlier and characterized by a higher number of pods per plant. For high concentration of EMS during long time and for combinations of physical and chemical mutagens, a significant decrease in plant height and stature was noticed, as compared to control. Besides, plants derived from gamma rays-treated seeds exhibited the highest 1000-seed weight. The novel induced variability may be integrated in rapeseed breeding program as a new germplasm with improved agronomic traits. Particularly, EMS1-7-stable mutant may be exploited to develop efficiently and quickly a new rapeseed cultivar with some desirable traits. The present study highlights once more the possibility to bring novel genetic diversity for rapeseed desirable traits improvement through mutation breeding.

La variabilité génétique est essentielle pour tout programme d'amélioration de plantes et la mutagénèse s'avère une technique incontestable d'induction de nouvelle variabilité génétique dans les germoplasmes des cultures. Chez le colza, une nouvelle variabilité génétique a été induite après traitement de semences par les rayons gamma, l'EMS et leur combinaison, en utilisant différentes doses et concentrations. L'objectif de cette étude est d'évaluer et comparer les mutants M 2 obtenus pour des caractères quantitatifs, dans deux environnements contrastés. Les paramètres étudiés sont d'ordre phénologique, morphologique et agronomique. Une grande variabilité a été observée et les traitements mutagènes ont eu un effet significatif sur tous les paramètres. Les mutants qui proviennent d'une faible concentration d'EMS, durant une période modérée, sont plus précoces et ont un nombre de siliques plus élevé que la variété témoin (non traitée). Par contre, des mutants dérivés de forte concentration d'EMS, pendant une longue période, et de la combinaison d'EMS avec les rayons gamma, ont montré une réduction significative de la hauteur et de la vigueur des plantes.
