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.

Objective: Wild indigenous fruits are believed to be extremely nutritious, contributing a great deal to the general health of the tribal and rural population. To validate this claim, systematic studies are required to estimate their nutritional composition. The objective of the study was to analyze the fatty acid composition of Syzygium zeylanicum (L.) DC. var. zeylanicum.Methods: The fatty acid composition of S. zeylanicum var. zeylanicum fruits were analysed by GC-MS/MS.Results: The major fatty acids were cis-oleic acid (43.47±0.62 %) and linoleic acid (31.14±0.35%). Total monounsaturated fatty acids in the sample was 44.21%. Omega-6, omega-7 and omega-9 fatty acids were detected. The polyunsaturated fatty acids in thefruits were linoleic acid (31.14±0.35 %) and arachidonic acid (0.15±0.22 %), whereas 24.51 % of the total fatty acids were saturated. The ratio of unsaturated to saturated fatty acids was approximately 3:1. The order of abundance of fatty acids, in some of the healthiest oils, viz. olive, canola, peanut oils is, Oleic acid>Linoleic acid>Palmitic acid>Stearic acid and the same order was observed in the present study.Conclusion: Fruits of S. zeylanicum var. zeylanicum too shows a healthy balance between unsaturated and saturated fats.

Fold Change Analysis

Interest on the enrichment of poultry meat with n-3 fatty acids has increased given its important role in human health. Flaxseed is the main sources of n-3 fatty acids, and contains between 45 to 71% of total fatty acids of the oil as α-linolenic acid. This paper reviews the plausibility of n-3 enrichment. Its focus is on the processing of flaxseed and begins by summarizing the benefits of supplementation on broiler performance. The literature on altering the FA deposition in different tissues is then reviewed, and the factors that affect the incorporation of n-3 PUFA into edible tissues of poultry are investigated. Flaxseed supplementation caused a reduction in the abdominal fat pad, and the main fatty acid deposited in the tissue is LNA. The use of fold-change analysis allowed interpreting and determining the variation of results within experiments that do not report data in similar units of measure. The fold change analysis identified three categories of desaturation response to feeding flaxseed to broilers, resulting in different values for EPA and DHA in both breast and thigh tissues: high, medium and low fold-changes. The use of flaxseed oil, whole or ground flaxseed 14 to 21 day before slaughter is recommended to poultry producers as feeding strategies to optimize n-3 enrichment, without compromising animal performance. Enriched DHA deposition could be accomplished feeding whole flaxseed.

Main Fatty Acid

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.

Chloroplasts, isolated from fresh spinach (Spinacia oleracea L.) were treated with four concentrations of each 2-chloro-4,6-bis(ethylamino)-s-triazine (simazine) or 2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine (atrazine) to determine the influence of these herbicides on the free fatty acid content in isolated chloroplasts. The treated chloroplast solutions were sampled at 0, 5, 15, 30, 60, and 120 min following treatment. Results indicated that most herbicide treatments increased free fatty acid content in isolated chloroplasts when compared with the zero concentration treatments. The increased fatty acid content was similar for most concentrations of simazine and atrazine. Results of individual fatty acid analyses indicated that the increase in total fatty acids was a result of increases in concentration of unsaturated rather than saturated fatty acids.

The triglyceride composition of the fat base of margarine used in the technology of flour confectionery products (FCP) includes up to 70 % monounsaturated acids, up to 25 % saturated ones. It has been established that for a more complete assimilation of FCP, a fat-intensive product should contain these fatty acids in equal proportions and should not contain trans-isomers of fatty acids, the main source of which are partially hydrogenated vegetable oils. Trans fats contained in margarines can cause the development of many diseases. It is known that the fat of sunflower flour is represented by unsaturated acids: linoleic (≈70 %) and oleic (≈18 %), which are of great physiological importance. The aim of the research was to optimize the fatty acid composition of cottage cheese bagel through the use of flour from sunflower seeds. The nutritional value of raw materials has been investigated. Tests of several variants of modification of cottage cheese bagel recipe in the process of baking laboratory samples have shown the advantage of sunflower flour in comparison with wheat flour in terms of the amount of fat, proteins, dietary fiber. The possibility of replacing 15 % of wheat flour with flour from sunflower seeds with a decrease in margarine by 19.8 % in bagel technology has been established. The product of the modified prescription composition contain more polyunsaturated fatty acids (by 28.4 %), of which linoleic - by 29.9 %, γ-linolenic - by 50 %, docosahexaenoic - by 20 %, eicosatrienic - by 35 %; less saturated fatty acids (by 6.2 %), of which caprylic - by 14.0 %, lauric - by 13.9 %, capric - by 10.7 %, myristic - by 9.6 %, butyric - by 9.1 %, palmitic - by 6.7 %; fewer transisomers of fatty acids (by 8.7 %), of which transisomers of oleic acid - by 9.6 %, linolenic - by 33.3 %. The proposed development has good consumer properties, and is characterized by a high content of protein (by 11.6 %) and dietary fiber (by 7.2 %).

The Impact

Cobia, Rachycentron canadum, is an important recreational marine fish of growing popularity in the aquaculture industry. Knowledge of the impact of environment on their fatty acids (FAs) utilization may contribute to the understanding their feeding in culture condition especially as cobia is been considered for low salinity culture. This study investigates the variations in the fatty acid contents of cobia from Dungun coast, Malaysia with respect to the changes in seasons and feeding intensity. Saturated fatty acids (FAs) comprised the majority of FAs in muscle, followed by monoenes, total poly-unsaturated fatty acids (PUFAs) (n-3) and then total PUFAs (n-6) with no seasonal variation in the quantity. A similar trend was observed in liver but total saturated FAs was significantly higher during the inter-monsoon while total monoenes significantly accumulate during monsoon. During low feeding intensity, there was a significant accumulation of PUFAs (n-6) in the muscle tissue (P < 0.05). Gut content analyses showed that cobia significantly increased the consumption of mollusks during the inter-monsoon (P < 0.05), although bony fishes dominated their diet throughout the year with no significant seasonal differences (P > 0.05). Our results suggest that cobia lipids are composed of a significant quantity of omega-3 and omega-6 FAs, which are considered to have important health benefits. While the environmental variability especially salinity fluctuations and prey abundance that accompany seasonal changes have a significant impact on the nutritional composition of cobia in Malaysian waters, their nutritional quality is maintained.

Fatty Acid Compositions

Lipid classes and fatty acid compositions of the farmed (F-C. gigas) and wild (W-C. gigas) pacific oysters, Crassostrea gigas, in Nha Trang, Vietnam were investigated for the first time. The results indicated that the lipid classes and fatty acid components of these oysters were insignificantly different. The total lipid of both studied oysters included six lipid classes, namely phospholipid (PL), sterol (ST), free fatty acid (FFA), triacylglycerol (TG), monoalkyldiacylglycerol (MADG), and hydrocarbon-wax (HW) in which TG and PL were dominated with the values of 48.4%, 41.8% for TG and 19.0%, 20.3% for PL in F-C. gigas and W-C. gigas, respectively. The fatty acids (FAs) content of F-C. gigas and W-C. gigas was similar. The saturated fatty acids (SFAs) content was 48.2% in total fatty acids (TFAs) of the F-C. gigas and 44.7% in TFAs of W-C. gigas, in which 16:0 was dominated in SFAs of both oysters with the value of 24.2% in F-C. gigas and 22.0% in W-C. gigas. The contents of monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (PUFAs) were 18.3%, 20.5% for MUFAs and 31.7%, 34.7% for PUFAs respectively in F-C. gigas and W-C. gigas. These MUFAs compositions contained 16:1n-7, 16:1n-5, 18:1n-9, 18:1n-7, 20:1n-11, 20:1n-9 and 20:1n-7, among them fatty acids 16:1n-7 (7.2% in F-C. gigas, 6.3% in W-C. gigas) and 18:1n-7 (6.6% in F-C. gigas, 7.4% in W-C. gigas) were the main MUFAs. PUFAs in these two oysters consisted of long-chain n-3 and n-6 fatty acids, in which 20:5n-3 (EPA) and 22:6n-3 (DHA) were dominated with the values of 12.7%, 13.9% for EPA in F-C. gigas and 6.5%, 6.0% for DHA in W-C. gigas.

The objective of this work was to evaluate suplemenation of vitamin C during feed training of giant trahira fingerlings. An experiment was established in a complete random design with seven treatments (0.0, 17.5, 52.5, 87.5, 122.5, 175.0 and 350.0 mg vitamin C/kg diet) and four repetitions. Giant trahira fingerlings (2.8 ± 0.2 cm) were distributed in 6-L aquaria at the density of 6 fish/L. A basal diet was formulated with 44.0% of crude protein and vitamin C and bovine heart were added in it daily. After 20 days, biometry of fish for evaluation of weight and length gains, rates of survival and cannibalism and uniformity of final length and for macroscopic observations of clinical signs of deficiency or excess of vitamin was carried out. After biometry evaluation, ten fish from each tested diet were collected for analysis of the fatty acid profile which was compared to profile of fish at the same life stage fed forage fish collected from breeding fishponds. Data on growth performance and fatty acid profiles were submitted to analyses of polynomial regression and uniformity of the final length was evaluated by the Bartlett test. There was a significant difference only for uniformity in final length and fatty acid profile of the carcass. Supplementation with 52.5 mg vitamin C/kg diet provided a greater uniformity of the final length of the fish. Fish from breeding fishponds presented lower concentration of PUFA (polyunsaturated fatty acids) and higher concentration of saturated fatty acids compared to fish trained to accept dry diets.

Pork meat samples were inoculated with high or low levels (106 or 103 CFU/g) of Salmonella Enteritidis, vacuum packaged, exposed to γ radiation (1.0, 2.5, and 4.7 kGy), and stored for 1 month at 4 ± 1°C. In highly contaminated samples, the target strain was completely eliminated only by the 4.7 kGy radiation dose, whereas in samples at the lower contamination level, 2.5 kGy was sufficient to eliminate Salmonella Enteritidis. The highest of the applied radiation doses reduced the aerobic microflora and extended the sample's refrigeration shelf life by at least 2 weeks. The fatty acid profile of pork meat was not significantly affected by any of the applied radiation doses. Irradiation increased the proportion of saturated fatty acids (SFA) and decreased the content of the polyunsaturated fatty acids (P &lt; 0.05). Irradiation also affected negatively the proportions of the nutritional indexes ω-6/ω-3, SFA/monounsaturated fatty acids, and SFA/polyunsaturated fatty acids. The proportion of the trans fatty acids C18:1ω-9 t9 and C18:2 t9,t12 in the total fatty acids was nearly doubled (90 and 86%, respectively) in the samples that had been exposed to 4.7 kGy. None of the applied radiation doses changed the lightness (L* value) of the meat, but redness (a*) and yellowness (b*) increased, particularly for the samples treated with 4.7 kGy.
