The Stability

Abstract Camelina sativa is well known due to high content of polyunsaturated fatty acids in its oil. Till now this oil has been studied mainly for applications as raw material for synthesis of resins, biodiesel and hydrocarbon fuels. This study examines the oxidative stability of cold-pressed Camelina sativa (also known as camelina, false flax or gold-of-pleasure) oil and its extracts of spices. Despite the high content of polyunsaturated fatty acids, Camelina sativa oil appeared more rigid against oxidation than rapeseed or flax oil. Extracts of different spices were prepared by maceration in camelina oil at room temperature for 24 h. The stability of extracts was determined under accelerated oxidation conditions and monitored by peroxide values. Most of the tested additives (e.g., bay leaves, allspice, clove, barley sprouts, coriander, ginger) did not influence or even decreased oxidative stability of the oil. However, oil with thyme additive demonstrated remarkably higher stability then Camelina sativa oil alone. Press-cakes of camelina seeds were extracted with two polar solvents (ethanol or water) and their mixtures under variable conditions (room temperature or reflux). Prepared polar extracts of press-cakes were characterised by total polyphenol content (Folin–Ciocalteu method) and antiradical activity against 1,1-diphenyl-2-picryl hydrazyl and galvinoxyl.

Storage Term

One of ways of developing the confectionary industry is a search for raw material resources with a high content of nutrients, useful for the human organism. A promising type of such raw materials is non-traditional oil seeds, especially chia seeds. The aim of the study was to estimate the oxidative stability of the lipid complex of creamy-shaken candies with chia seeds at storage. It is noted, that lipase of chia seeds doesn’t manifest activity in an acid medium. That is why chia seeds introduction to creamy-shaken candies (with рН<6,0) doesn’t accelerate hydrolytic disintegration of their lipid component at storage. A type of jelly-former, used at candy production (agar-agar, pectin, modified starch), doesn’t influence the accumulation dynamics of free fatty acids in candies. It is noted, that the lipid component of creamy-shaken candies, produced with agar-agar and pectin, is characterized with the equal dynamics of a peroxide value. The accumulation of peroxide compounds in starch products takes place slower. It has been established, that despite the high content of polyunsaturated fatty acids, the lipid component of candies with chia seeds comparing with control is characterized by less inclination to oxidation. It is noted, that at the 30th day of storage relative changes of peroxide value indices of products with supplements are 1.00 and 0.81 against 1.85 and 1.49 in control samples on agar-agar (pectin) and starch respectively. The braking effect of chia seeds on oxidizing processes is conditioned by the high content of tocopherols and phenol compounds (quercetin, coffee, chlorogenic acids, rutin, polyphenol compounds) with antioxidant properties in them. It has been established, that during the studied storage term products didn’t gain a rancid smack, testifying to the accumulation of secondary oxidation processes. The structure and color of the studied samples of candies didn’t also change. That is during the normative storage term (60 days) creamy-shaken candies with chia seeds correspond to normative requirements by organoleptic parameters and quality ones of the lipid complex.

The aim of the present study was to determine the effect of supplementing the diets of broiler chickens with Camelina sativa oil or cake as a source of polyunsaturated fatty acids (PUFAs) on their growth performance, fatty acid profile, and sensory quality of meat. The 456 Ross 308 broilers aged 21–42 days were divided into 3 groups with 4 replicates of 38 birds in each. Chickens in the control group I (CTR) were fed a standard grower–finisher feed mixture containing 60 g/kg rapeseed oil. The experimental components, C. sativa oil—CSO (group II) or cake—CSC (group III), were included in a diet based on wheat and soybean at 40 and 100 g/kg, respectively. The use of Camelina oil and cake as feed components did not have a significant effect on the growth performance of the chickens. Analysis of the fatty acid profile in the lipids of the breast muscles showed that Camelina oil and cake reduced the content of monounsaturated fatty acids (p < 0.05) but increased the content of n-3 polyunsaturated fatty acids, especially α-linolenic acid (C18:3) (p < 0.01). Furthermore, both components reduced the ratio of n-6/n-3 PUFAs in the breast muscles (p < 0.01). Sensory analysis revealed that Camelina oil had a beneficial effect on meat juiciness, whereas Camelina cake slightly worsened the flavor and tastiness of the meat. In conclusion, supplementing the diet of broiler chickens with Camelina oil or cake can be an efficient method for modifying the fatty acid profile of the meat lipids in a beneficial way, without any negative impact on the growth performance of the chickens. According to the dietetic recommendations for humans, broiler chicken meat with a higher level of PUFA n-3 can be a good alternative source of these fatty acids in the human diet. Furthermore, Camelina oil improved the juiciness of breast meat.

Inflammatory Effect

Polyunsaturated fatty acids (n-3 PUFAs) are long-chain polyunsaturated fatty acids with 18, 20 or 22 carbon atoms, which have been found able to counteract cardiovascular diseases. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), in particular, have been found to produce both vaso- and cardio-protective response via modulation of membrane phospholipids thereby improving cardiac mitochondrial functions and energy production. However, antioxidant properties of n-3 PUFAs, along with their anti-inflammatory effect in both blood vessels and cardiac cells, seem to exert beneficial effects in cardiovascular impairment. In fact, dietary supplementation with n-3 PUFAs has been demonstrated to reduce oxidative stress-related mitochondrial dysfunction and endothelial cell apoptosis, an effect occurring via an increased activity of endogenous antioxidant enzymes. On the other hand, n-3 PUFAs have been shown to counteract the release of pro-inflammatory cytokines in both vascular tissues and in the myocardium, thereby restoring vascular reactivity and myocardial performance. Here we summarize the molecular mechanisms underlying the anti-oxidant and anti-inflammatory effect of n-3 PUFAs in vascular and cardiac tissues and their implication in the prevention and treatment of cardiovascular disease.
