The deep red colour of the fruits of Palisota barteri results from a high content of Carotenoids. The main pigment now has been identified as β-Citraurin. It is esterified with the saturated fatty acids from C4, C6 ... up to C18. The main fatty acid is lauric acid. Minor pigments are Zeaxanthin and Cryptoxanthin, both esterified in the same manner as β-Citraurin, and β-Apo-8′-carotinal, β- and ξ-Carotin and a very small amount of Lycopin.

Dikiri, an abnormal type of coconut found mainly in the southern part of Sri Lanka, was analyzed for its proximate composition, dietary fiber, minerals, vitamin C and fatty acid profile. Pectin was isolated and characterized (moisture, ash, acetyl value, methoxyl value, equivalent value) from dikiri coconut. Dikiri coconut contains 38.91± 0.9%, 2.95 ± 0.2%, 58.21± 3.6%, 17.62 ± 0.2%, 6.63 ± 0.3% and14.59% dry matter, ash, crude fat, crude fibre and carbohydrate respectively. The main dietary fiber components of Dikiri coconut were pectin and hemicellulose while that of normal coconut was cellulose. Lignin content was significantly lower in the kernel of dikiri coconut(3.98±0.9) than normal coconut kernel(6.14±0.7%). Equivalent weight, methoxyl value, moisture, ash and acetyl value of dikiri pectin were 1052.7 ± 11.08, 8.72 ± 0.25, 85.8 ±1.65, 0.8 ± 0.04 and 0.09 ± 0.01 respectively. The main mineral found in dikiri was potassium. Vitamin C content of dikiri coconut was 2.32 mg/100g. The fatty acids composition of dikiri was similar to normal coconut and saturated fatty acids constituted nearly 90% of total fatty acids and lauric acid is the main fatty acid followed by myristic acid.

The efforts to modify the fatty acid composition of milk have intensified with health conscious nutrition coming to the forefront.This experiment of ours was designed to investigate to what extent the natural-based feed additives, such as oilseeds, can influence the fatty acid composition of cow’s milk.Further information was gained about feeding of oilseeds in specific amounts to be fitted into the technology of a large-scale dairy farm in practice. The feed supplements were whole, untreated rapeseed and whole, untreated linseed, as part of a total mixed ration. In case of saturated fatty acids when supplementing with whole rapeseed the most significant change was observable in the concentration of the caprylic acid, capric acid, undecylic acid, lauric acid, myristic acid, stearic acid. In case of unsaturated fatty acids the quantity of oleic acid enhanced considerably. When observating the feeding with whole linseed the concentration of many saturated fatty acids lowered (caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid). The quantity of some unsaturated fatty acids was showing a distinct rise after feeding with linseed, this way the oleic acid, α-linolenic acid, conjugated linoleic acid, eicosadienoic acid. The aim of the study was to produce food which meets the changed demands of customers, as well.

The earthworm Eudrilus eugeniae is a well-known source of protein in animal feeding but there is lack of information on its fatty acid profile. This study aimed to determine its nutrient components and fatty acid profile. Earthworms were bred in substrate containing organic matter; peanut powder was added in the experimental group diet. The nutrient components (protein, ash, and minerals) of the adult worms were determined according to the Kjeldahl method and by atomic absorption spectrophotometer. The fatty acid profile was determined by gas chromatography / mass spectrometry. The dry-matter protein content significantly increased in worms fed peanut powder (p < 0.05) as did the minerals measured. The main fatty acid families had similar proportions in the groups. In the saturated fatty acids, C12:0 and C18:0 were present in higher proportions in both groups, whereas in monounsaturated fatty acids, C18:1ω9 prevailed. Significant differences (p < 0.05) in polyunsaturated fatty acids were observed between the two groups. An increase in the proportion of ω6 and ω3 was observed in the experimental group compared to the control. This study showed that peanut powder significantly influenced nutrient components of E. eugeniae. The fatty acid profile of this species was similar to that of most animals. Earthworms’ diet can be altered to improve the nutritional value of E. eugeniae.

This study aimed to detect the fatty acid profile and oxidative stability traits of hazelnuts dried using three different methods: artificial drying (AR), concrete ground (CN), and grass ground (GS) during 12 months of storage (2013–2014) at 20–25°C and 70–90% relative humidity. As expected, monounsaturated fatty acids (MUFA) were the main fatty acid group (81.75–83.59%) followed by polyunsaturated fatty acids (10.20–11.48%) and saturated fatty acids (5.38–6.96%). Samples dried in AR had more MUFA (83.59%) than sun-dried (CN and GS) samples. Following the drying process, the lowest peroxide value (PV) and the highest ratio of oleic-to-linoleic acid (8.27%) were recorded in samples dried in AR. At the end of storage, the PV was lower in samples dried in AR than on CN and GS methods. The results of this research showed that the AR method is the best for drying hazelnut. This research, therefore, recommends the AR method for drying hazelnuts on a commercial scale.

SummaryPlatelet aggregation and its relation to fatty acid composition of platelets, plasma and adipose tissue was determined in 196 randomly selected, free-living, 40-49-year-old men in two regions of Finland (east and southwest) with a nearly twofold difference in the IHD rate.There were no significant east-southwest differences in platelet aggregation induced with ADP, thrombin or epinephrine. ADP-induced platelet secondary aggregation showed significant negative associations with all C20-C22 ω3-fatty acids in platelets (r = -0.26 - -0.40) and with the platelet 20: 5ω3/20: 4ω 6 and ω3/ ω6 ratios, but significant positive correlations with the contents of 18:2 in adipose tissue (r = 0.20) and plasma triglycerides (TG) (r = 0.29). Epinephrine-induced aggregation correlated negatively with 20: 5ω 3 in plasma cholesteryl esters (CE) (r = -0.23) and TG (r = -0.29), and positively with the total percentage of saturated fatty acids in platelets (r = 0.33), but had no significant correlations with any of the ω6-fatty acids. Thrombin-induced aggregation correlated negatively with the ω3/6ω ratio in adipose tissue (r = -0.25) and the 20: 3ω6/20: 4ω 6 ratio in plasma CE (r = -0.27) and free fatty acids (FFA) (r = -0.23), and positively with adipose tissue 18:2 (r = 0.23) and 20:4ω6 (r = 0.22) in plasma phospholipids (PL).The percentages of prostanoid precursors in platelet lipids, i. e. 20: 3ω 6, 20: 4ω 6 and 20 :5ω 3, correlated best with the same fatty acids in plasma CE (r = 0.32 - 0.77) and PL (r = 0.28 - 0.74). Platelet 20: 5ω 3 had highly significant negative correlations with the percentage of 18:2 in adipose tissue and all plasma lipid fractions (r = -0.35 - -0.44).These results suggest that, among a free-living population, relatively small changes in the fatty acid composition of plasma and platelets may be reflected in significant differences in platelet aggregation, and that an increase in linoleate-rich vegetable fat in the diet may not affect platelet function favourably unless it is accompanied by an adequate supply of ω3 fatty acids.

Abstract Background Cottonseed is one of the major sources of vegetable oil. Analysis of the dynamic changes of fatty acid components and the genes regulating the composition of fatty acids of cottonseed oil is of great significance for understanding the biological processes underlying biosynthesis of fatty acids and for genetic improving the oil nutritional qualities. Results In this study, we investigated the dynamic relationship of 13 fatty acid components at 12 developmental time points of cottonseed (Gossypium hirsutum L.) and generated cottonseed transcriptome of the 12 time points. At 5–15 day post anthesis (DPA), the contents of polyunsaturated linolenic acid (C18:3n-3) and saturated stearic acid (C18:0) were higher, while linoleic acid (C18:2n-6) was mainly synthesized after 15 DPA. Using 5 DPA as a reference, 15,647 non-redundant differentially expressed genes were identified in 10–60 DPA cottonseed. Co-expression gene network analysis identified six modules containing 3275 genes significantly associated with middle-late seed developmental stages and enriched with genes related to the linoleic acid metabolic pathway and α-linolenic acid metabolism. Genes (Gh_D03G0588 and Gh_A02G1788) encoding stearoyl-ACP desaturase were identified as hub genes and significantly up-regulated at 25 DPA. They seemed to play a decisive role in determining the ratio of saturated fatty acids to unsaturated fatty acids. FAD2 genes (Gh_A13G1850 and Gh_D13G2238) were highly expressed at 25–50 DPA, eventually leading to the high content of C18:2n-6 in cottonseed. The content of C18:3n-3 was significantly decreased from 5 DPA (7.44%) to 25 DPA (0.11%) and correlated with the expression characteristics of Gh_A09G0848 and Gh_D09G0870. Conclusions These results contribute to our understanding on the relationship between the accumulation pattern of fatty acid components and the expression characteristics of key genes involved in fatty acid biosynthesis during the entire period of cottonseed development.

AbstractThe metabolic impact of circulating fatty acids (FAs) in patients requiring hemodialysis (HD) is unknown. We investigated the associations between plasma triglyceride (TG) FAs and markers of inflammation, insulin resistance, nutritional status and body composition. Plasma TG-FAs were measured using gas chromatography in 341 patients on HD (age = 55.2 ± 14.0 years and 54.3% males). Cross-sectional associations of TG-FAs with 13 markers were examined using multivariate linear regression adjusted for potential confounders. Higher levels of TG saturated fatty acids were associated with greater body mass index (BMI, r = 0.230), waist circumference (r = 0.203), triceps skinfold (r = 0.197), fat tissue index (r = 0.150), serum insulin (r = 0.280), and homeostatic model assessment of insulin resistance (r = 0.276), but lower malnutrition inflammation score (MIS, r =  − 0.160). Greater TG monounsaturated fatty acid levels were associated with lower lean tissue index (r =  − 0.197) and serum albumin (r =  − 0.188), but higher MIS (r = 0.176). Higher levels of TG n-3 polyunsaturated fatty acids (PUFAs) were associated with lower MIS (r =  − 0.168) and interleukin-6 concentrations (r =  − 0.115). Higher levels of TG n-6 PUFAs were associated with lower BMI (r =  − 0.149) but greater serum albumin (r = 0.112). In conclusion, TG monounsaturated fatty acids were associated with poor nutritional status, while TG n-3 PUFAs were associated with good nutritional status. On the other hand, TG saturated fatty acids and TG n-6 PUFAs had both favorable and unfavorable associations with nutritional parameters.

An optimal fatty acid (FA) profile during pregnancy, especially docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), is essential for the health of the mother and child. Our aim was to identify the socioeconomic and maternal lifestyle factors associated with serum FA concentration in pregnant women. A longitudinal study was conducted on 479 pregnant women, who were assessed during the first (T1) and third (T3) trimesters of pregnancy. Data on maternal characteristics, food consumption, and lifestyle were collected. Serum FA concentrations were analysed by a gas chromatography–mass spectrometry combination. The multiple linear regression showed that high educational level and older age were significantly associated with higher EPA and DHA concentrations and lower values of n-6/n-3 and arachidonic acid (AA)/EPA in T1 and/or T3. Regarding diet—fish and seafood consumption increased EPA concentration and reduced n-6/n-3 and AA/EPA values in both trimesters, whereas its consumption increased DHA concentration only in T1. Smoking was associated with lower DHA concentration in T1 and higher values of n-6/n-3 ratio in both trimester. Overweight and obesity were associated with higher values of n-6/n-3 ratio and AA/EPA ratio in T1. A statistically non-significant association was observed with saturated fatty acids (SFA) and monounsaturated fatty acids (MUFA). In conclusion, high educational levels, older age, fish, seafood consumption, and/or non-smoking, are factors that influence better omega-3 polyunsaturated fatty acid (n-3 PUFA) profile in both trimesters of pregnancy. Further research is needed to go in-depth into these findings and their health consequences.
