Valorization of camelina oil to biobased materials and biofuels for new industrial uses: a review

Abstract

This review gathers current research work, and strategies for valorization of an emerging non-food camelina oil seed crop into renewable polymers building blocks for industrial applications, current challenges, and future opportunities.

Oil Bodies from Chia (Salvia hispanica L.) and Camelina (Camelina sativa L.) Seeds for Innovative Food Applications: Microstructure, Composition and Physical Stability

“…The lipid content of the chia seeds used in this study was 35.3 ± 0.2 g/100 g, which was in accordance with the literature [9,45,46]. The camelina seeds contained 42.1 ± 1.6 g/100 g of lipids, also in agreement with previous reports [18,19]. Both the chia and camelina seeds are rich in oil and are therefore suitable oilseeds for the preparation of foods such as oil-in-water emulsions.…”

Improving the Barrier and Mechanical Properties of Paper Used for Packing Applications with Renewable Hydrophobic Coatings Derived from Camelina Oil

“…Camelina oil from an emerging oil seed crop Camelina sativa contains a high proportion of the unsaturated fatty acids linolenic acid (40%), linoleic acid (23%), oleic acid (16%), and eicosenoic acid (15%) . For this reason, camelina oil was chosen to be used as a hydrophobic coating material for paper substrates after its grafting with maleic anhdride.…”

“…To fill this gap, the current study was carried out to explore the utility of camelina oil as a renewable hydrophobic coating material after its single-step modification with maleic anhydride in the absence of solvent or any additional catalyst. Camelina oil has the potential to replace petroleum-derived coatings and additives because it is renewable, nontoxic, and highly unsaturated. , Maleic anhydride, as a source of alkenyl succinic anhydride, is known to increase the hydrophobicity of the material or product . Newly developed maleic anhydride-grafted camelina oil, as a sustainable hydrophobic coating material, was characterized and evaluated for its hydrophobicity, mechanical, and moisture barrier properties on paper substrates that could potentially be utilized in the paper packaging industry.…”

Eco-Friendly Photoreversible Adhesives Derived from Coumarin-Functionalized Epoxy Soybean Oil

“…Vegetable oils are one of the eco-friendly feedstocks extensively used as an alternative starting material for synthesizing a variety of polymeric networks due to their abundance, low toxicity, biodegradability, and low cost. − Moreover, they are highly adaptable and reactive because oils from various sources include numerous functional groups, including double bonds and hydroxyl and ester groups, which are suitable for a variety of chemical processes. , Soybean oil (SBO) is the second most available vegetable oil next to palm oil, with a global production of 62 million tons in 2021–2022, and is used for food and industrial applications. , SBO contains nearly 80% of unsaturated fatty acids such as oleic acid, linolenic acid, and linoleic acid, which are easily converted to epoxy groups in the presence of hydrogen peroxide and acid . Epoxidized soybean oil (ESO) is used as a green plasticizer for various polymers, such as polylactic acid , and polyvinyl chloride , and is also used to synthesize epoxy resins. − Further, ESO can be modified with acrylic acid, allyl alcohol, and hydroxyethyl acrylate to synthesize coatings, foams, and adhesives via an efficient free radical polymerization. ,− Moreover, several hydroxylation processes can convert ESO into polyols to manufacture polyurethane. − However, to date, only a few efforts have been made to synthesize reworkable (healable) polymer networks using ESO .…”
