The present study was conducted to assess the effect of supplementation of peanut paste with 0, 10, 20, 30, 40 and 50% sesame seed paste on the fatty acid profile and oil stability of butter made from the blends. Packaged samples from each blend were stored at ambient temperature (27±2oC) for 12 weeks and analysed for oil separation, peroxide value (PV) and acid value (AV) at four weeks interval. Unblended peanut and sesame seed butters served as control samples. The result showed that apart from behenic acid that was not detected in sesame butter oil, the other eight fatty acids detected in peanut butter oil were also found in sesame butter oil but in varying quantities. Oil extracted from 100% peanut and sesame seed butters contained slightly below 20% saturated fatty acids (SFAs) and slightly above 80% unsaturated fatty acids (UFAs). Palmitic, palmitoleic, oleic, linolenic, arachidic and behenic acids decreased while stearic, linoleic, and eicosenoic acids increased with increase in sesame paste supplementation. Butters made from blended pastes had higher percentages of SFAs and polyunsaturated fatty acids (PUFAs) but lower percentage of monounsaturated fatty acid (MUFAs) than 100% peanut butter oil. Oil separation, PV and AV significantly (P = .05) increased with storage time. Quantity of oil separated at week 12 ranged from 1.05% to 3.19%. The rate of peroxide formation decreased with increase in sesame paste supplementation. Consequently, at week 12, while 10% sesame paste supplemented butter recorded 263.12% increment in PV, the value for 50% sesame paste supplemented butter was 143.01%. The treatment had no effect on acid value during storage. At week 12, the AV increment for the butters from the blended pastes ranged from 179.59% to 181.82% while the values for 100% peanut butter and 100% sesame butter were 183.72% and 119.64% respectively. The study has shown that butter of high unsaturated fatty acids with delayed onset of oxidative deterioration could be produced from peanut paste supplemented with sesame seed paste.

AbstractThis study quantified the fatty acid profile with emphasis on the stereo-specifically numbered (sn) 2 positional distribution in TAG and the composition of main phospholipids at different lactation stages. Colostrum milk (n 70), transitional milk (n 96) and mature milk (n 82) were obtained longitudinally from healthy lactating women in Shanghai. During lactation, total fatty acid content increased, with SFA dominating in fatty acid profile. A high ratio of n-6:n-3 PUFA was observed as 11:1 over lactation due to the abundance of linoleic acid in Chinese human milk. As the main SFA, palmitic acid showed absolute sn-2 selectivity, while oleic acid, linoleic acid and α-linolenic acid, the main unsaturated fatty acids, were primarily esterified at the sn-1 and sn-3 positions. Nervonic acid and C22 PUFA including DHA were more enriched in colostrum with an sn-2 positional preference. A total of three dominant phospholipids (phosphatidylethanolamine (PE), phosphatidylcholine (PC) and sphingomyelin (SM)) were analysed in the collected samples, and each showed a decline in amount over lactation. PC was the dominant compound followed by SM and PE. With prolonged breast-feeding time, percentage of PE in total phospholipids remained constant, but PC decreased, and SM increased. Results from this study indicated a lipid profile different from Western reports and may aid the development of future infant formula more suitable for Chinese babies.

The objective of this research was to assess the effects of including oil-rich feedstuffs in diets for lactating goats on the fatty acid (FA) profile of their milk. Thirty-six Murciano-Granadina goats were randomly assigned to three treatment groups, namely a control diet (CTRL), a diet based on whole rapeseed (RS), and a diet based on pumpkin seed cake (PSC). The diets were composed of 1 kg hay (70 % Italian ryegrass, 30% alfalfa) and 1.24 kg concentrate, and were formulated to be isoenergetic and isonitrogenous. Milk yield and its contents of protein, fat and lactose did not differ significantly among the groups. However, including oil-rich feeds in the diet altered the fatty acid profile of the milk significantly, decreasing its saturated fatty acid (SFA) content and increasing its content of unsaturated fatty acids (UFAs). Effects on polyunsaturated fatty acids (PUFAs), conjugated linoleic acid (CLA), and the n-6 to n-3 ratio depended on the source of dietary lipids. The PSC augmented diet increased the relative amount of PUFAs and fatty acid methyl esters (FAME) in milk (+25 %) significantly In comparison with CTRL, whereas the RS diet produced a limited and statistically insignificant increase (+7.5%). The concentration of CLA was higher in milk from does fed the PSC diet, whereas the n-6 to n-3 ratio was lower in milk from does fed RS. These preliminary results form the basis for developing premium dairy products that are enriched in fatty acids that are more favourable for human health.

Abstract Background: Amount of fat and carbohydrate in maternal diet during gestation and lactation has permanent effects on fetal metabolism. SIRT1 is a nutrient-responsive histone deacetylase that modulates the lipid and glucose metabolism in response to energy stress and extends life span. Herein, we assessed the effects of carbohydrate and fat distribution in a maternal isocaloric diet on fetal gene and protein levels of SIRT1, as well as liver fatty acid profile. Twenty C57BL/6 female mice were inseminated and randomly received the AIN 93G isocaloric pair-fed LF-HC (16% and 64% of calorie as fat and carbohydrate) or HF-LC (48% and 32% of calorie as fat and carbohydrate) diet during gestation and lactation. After weaning, all offspring received LF-HC diet up to the adolescence. Liver tissue were extracted for final analysis. Results: SIRT1 gene and protein levels were lower in both sexes born from HF-LC-fed mothers than LF-HC-fed one, significant differences were only observed between males in the gene expression (p<0.001) and females in protein level (p<0.001). Saturated fatty acids and cholesterol were increased while unsaturated fatty acids decreased at the liver of male and female offspring born from HF-LC-fed mothers (p<0.001). Conclusions: Maternal dietary fat and carbohydrate distribution, regardless of calorie intake, modify the offspring hepatic fatty acid profile, as well as SIRT1 gene and protein expression which effects on life span.

AbstractMarine fish are a good source of unsaturated fatty acids, high nutritional value protein, vitamins and minerals. Baltic herring is one of the most frequently caught fish in Poland(1). It was demonstrated that the fishing season has an effect on the content of individual fatty acid fractions(2).The aim of the study was to analyse the fatty acid profile of Baltic herring flaps originating from two fishing seasons.The study material were flaps of Baltic herring (Clupea harengus) originating from two fishing seasons (April-June following spawning and October-December prior to spawning). For each fishing season, six batches of raw material were examined (n = 6). From each batch, flaps were taken from ten fish. The flaps were comminuted and thoroughly mixed to prepare an experimental sample from which adequate weights of analytical samples were taken. The quantitative and qualitative analysis of the fatty acid composition was conducted following the cold muscle lipid extraction with a mixture of chloroform : methanol (2:1). Fatty acid methylation was carried out with a chloroform : methanol : sulphuric acid mixture (100:100:1). The separation of fatty acids was performed by gas chromatography. A one-factor variance analysis method with Duncan's test (P ≤ 0.05) was used to evaluate the variation of mean values.The fishing season does not significantly affect the content of saturated and unsaturated fatty acids. Differences were found during the analysis of the individual groups of unsaturated acids. The amount of monounsaturated fatty acids in herring before spawning (25.27%) was significantly lower than that after spawning (35.91%) (P ≤ 0.05). The content of polyunsaturated fatty acids before spawning (43.99%) was significantly higher than that after spawning (33.49%) (P ≤ 0.05). Most changes in the fatty acid profile occur in the highly unsaturated fatty acids (HUFA). The most important change due to the health-promoting properties for humans is an increase in the amount of EPA from 6.24% to 9.84% after and before spawning, respectively. Analogous changes were demonstrated for DHA, whose amount increased from 9.64% to 24.56%. The obtained results demonstrate a more favourable fatty acid profile in herring caught before spawning.

Abstract Indian major carps are the widely consumed fish species of Pakistan, being a cheap source of proteins and unsaturated fatty acids, they are good for cardiovascular health. Water pollution due to discharge of untreated industrial waste water into water bodies contaminates this precious source of nutrients. The present study therefore, was aimed to assess deterioration of fatty acid profile of three Indian major carp species due to different concentrations of industrial wastes. The water samples were collected from the river Chenab at the site where it receives industrial wastewater via Chakbandi drain. After exposure to 1.5%, 3.0%, and 4.5% dilutions of collected water in different aquaria it was observed that proportion of unsaturated fatty acids in selected fish species were decreased significantly as the intensity of the dose increased (P < 0.05). Conversely the level of saturated fatty acids increased with the increasing dose of treatment (P < 0.05). These findings suggest that untreated wastewater not only deteriorate the fatty acid profile of aquatic animals but also these toxic substances can reach human body through fish meat and pose further health hazards. Therefore, it is highly recommended that industrial effluents should be treated before they are dumped into water bodies.

The objective of this study was to determine the chemical characteristics of sliced beef dendeng and ground beef dendeng circulating in Malang city, i.e., fat content, fatty acid profile, moisture content, water activity and total calories. The quantitative descriptive analysis was used as research design. The data obtained were analyzed statistically by using the calculation formula according to the method used. The sliced dendeng and ground dendeng circulating in Malang city was used as sample. Beef dendeng circulating in Malang city had a fat content of 3.43-6.77%, moisture content of 19.56-27.50%, water activity of 0.69-0.84, and total calories of 93.38-136.77 kcal. The sliced beef dendeng with the best chemical characteristics (closed to national standard) was tested for fatty acid profile analysis. About 37 fatty acids were identified, consisting of 19 saturated fatty acids and 18 unsaturated fatty acids. It was concluded that both types of beef dendeng circulating in Malang city had different fat content, fatty acid profile, moisture content, water activity and total calories. These differences were influenced by raw materials, spices and processing used.
