“…One of the main advantages of camelina compared with oilseed rape is the extreme drought tolerance, also at germination phase [10]. The presence of mucilage in camelina seeds, which account for about 7-10% of the seed mass [24], might confer this oilseed crop a great ability to overcome drought stress at early seedling stage. Unfortunately, when camelina seeds are processed for feed uses, the mucilage sticks to the cake lowering its value, causing slow fat assimilation in the livestock [25].…”

One of the main advantages of camelina (Camelina sativa (L.) Crantz) is its wide environmental adaptability and extreme drought tolerance. The availability of both winter and spring camelina biotypes, characterized by different seed sizes, raises the question about possible differences in their response to drought stress at the emergence stage. To address this, a germination test was set up in controlled conditions, comparing six winter and six spring genotypes with differing seed sizes (ranging from 1.83 to 0.88 g/1000-seeds) under increasing levels of osmotic stress (0, −0.4, −0.8, −1.2, −1.4, −1.6 MPa) using polyethylene glycol (PEG). Camelina withstands mild level of osmotic stress (−0.4 MPa) without significant decrease in germination. Even at −1.2 MPa after 10 d, it still had 75% germination. Significant differences in germination were observed between biotypes, where spring biotypes performed better than winter ones. Shoot and radicle lengths were significantly diminished by imposed osmotic stress, but shoot growth seemed more impacted. In general, spring biotypes had longer shoots and radicles than winter ones. Seed size played a role in the response of camelina to drought, but it depended on biotype and stress level imposed. In particular large seeded spring types had the highest germination percentage and resulted less impaired by osmotic stress, otherwise among the tested winter types the small seeded ones were the best performing. The presented data could be useful for breeding purposes for selecting the appropriate camelina type for sowing in drought-prone regions.

“…It is important to highlight that the methodology proposed in the present work for mucilage extraction only implies the use of a stirring device and high‐intensity ultrasound equipment, allowing the process to be easily scaled to higher volumes. In fact, a recent work reported the feasibility to scale up ultrasound processes by using tubular reactors with continuous or recirculation operation modes, which showed high extraction yields of another seed mucilage: Camelina sativa 26 . Additionally, the time of ultrasound treatment proposed in the present work was very low compared with other studies 16,17 …”

BACKGROUND The application of chia mucilage still remains restricted due to the difficulty in achieving high extraction yields. The effect of ultrasonic‐assisted extraction (UAE) conditions (temperature, seed:water ratio and time) on the rheological properties of chia mucilage extracts and the relation to the proportion of translucent phase (TP) and opaque phase (OP) of the mucilage in the extract were evaluated. RESULTS UAE allowed the efficient extraction of chia mucilage from chia seeds. The desired overall optimal combination to maximize both yield and apparent viscosity was achieved at a seed:water ratio 1:10, a temperature of 25.3 °C and 53.7 min extraction time; the optimal conditions to obtain the maximum yield and minimum apparent viscosity were a seed:water ratio close to 1:20, temperature of 48.8 °C and 208.4 min extraction time. CONCLUSION The results obtained in the present work demonstrated that the differences in rheological properties of chia mucilage extracts are due to the extraction methods used. Therefore, it is possible to modulate the extraction conditions in order to obtain different characteristics of the mucilage, maintaining a high extraction yield. © 2022 Society of Chemical Industry.

“…The beneficial role of these ingredients in digestion is confirmed by long-term human consumption of bread enriched with camelina seeds available in the Danish supermarkets in various recipes (Zubr 2010). When extracted, fibers are valued as supplements in the human diet, while mucilage can easily find pharmaceutical and food applications (Fabre et al 2020;Ubeyitogullari and Ciftci 2020). Due to the presence of bioactive compounds with beneficial effects on human health, oil produced from cold-pressed camelina seeds is extremely valuable (Ubeyitogullari and Ciftci 2020; Schmidt and; Pokorný 2005) since the majority, but not all, of them are soluble in oil.…”

Promoting crop diversification in European agriculture is a key pillar of the agroecological transition. Diversifying crops generally enhances crop productivity, quality, soil health and fertility, and resilience to pests and diseases and reduces environmental stresses. Moreover, crop diversification provides an alternative means of enhancing farmers’ income. Camelina (Camelina sativa (L.) Crantz) reemerged in the background of European agriculture approximately three decades ago, when the first studies on this ancient native oilseed species were published. Since then, a considerable number of studies on this species has been carried out in Europe. The main interest in camelina is related to its (1) broad environmental adaptability, (2) low-input requirements, (3) resistance to multiple pests and diseases, and (4) multiple uses in food, feed, and biobased applications. The present article is a comprehensive and critical review of research carried out in Europe (compared with the rest of the world) on camelina in the last three decades, including genetics and breeding, agronomy and cropping systems, and end-uses, with the aim of making camelina an attractive new candidate crop for European farming systems. Furthermore, a critical evaluation of what is still missing to scale camelina up from a promising oilseed to a commonly cultivated crop in Europe is also provided (1) to motivate scientists to promote their studies and (2) to show farmers and end-users the real potential of this interesting species.
