Stage of lactation (SOL) is a major factor affecting several characteristics of milk such as fatty acids content and composition, protein and main minerals content. These variations may have important quantitative and qualitative consequences on the characteristics of cheese. The aim objective of this study was to analyse the effect of lactation stage on the fat and fatty acids composition of the artisanal camembert type-cheese made from cow’s milk collected in Mostaganem region (Algeria) and provided from three stages of lactation (early, mid and late). In this study and for each stage of lactation, the fat and fatty acid composition of camembert type-cheese were analysedand evaluated. Results showed that the total lipids were related to the stageof lactation (p<0.05), ranging from 14.6% for the 3rd SOL to 23% for the 1stSOL. The fatty acids composition of Camembert-type cheese showed a highpolyunsaturated fatty acids percentage dominated by ω6 and ω3 fatty acidsrepresented by linoleic and α-linolenic acids. Indeed, they recorded maximum values of 2.53% and 0.6% respectively, for the Camembert made withthe milk of the 1st SOL (p<0.05). Concerning monounsaturated fatty acidsclass, oleic acid is found to be the most important fatty acid with a maximumpercentage (26.1%) in Camembert of the 1st SOL (p<0.05). Finally, this studyconcluded that the stage of lactation plays a determining role on the biochemical composition of the camembert type-cheese, particularly on lipidsand essential fatty acids.

The effect of the stage of lactation, the number of foals and age of the mare on changes in the fat content and fatty acid composition of colostrum and milk of primitive Konik horses was investigated. Colostrum and milk samples from 12 lactating mares were collected at the beginning of lactation, on the days 1 and 2 after foaling and then, starting from the first month of lactation, at 4-week intervals up to the sixth month of lactation. Significant differences were observed in fat content as well as the composition of some analysed fatty acids between colostrum and milk of mares of the Konik breed. The number of foalings and the age of mares did not have a statistically significant effect on the fat content in milk and had only a slight effect on the fatty acid composition. Milk produced by mares of the Konik breed is characterized by a considerable content of polyene fatty acids with 18 carbon atoms, a low ratio of n-6 fatty acids to n-3 fatty acids as well as low, highly advantageous values of atherogenic and thrombogenic indices.

Sicana odorifera seeds, from an ancestral Cucurbita growing in Paraguay, possess important biowaste after fruit pulp use. However, there are reports that its infusions can reduce and cure the symptoms of viral diseases such as hepatitis, denoting its medicinal properties. The recovery of nutrients and bioactive molecules from its bio-residues has potential uses in the industrial sector with high added value as functional food ingredients. In S. odorifera species, although it is not a fruit for mass consumption, it is precisely the lack of a market for its biowaste that has limited its integral use. Based on this, the centesimal composition, oil characterization, and fatty acids profile of the kurugua seeds from two accessions (atropurpurea (black) and reddish) were studied. Kurugua seeds have been subjected to a cold extraction with a hydraulic press from dried whole seeds, and ISO and AOCS standard methods were used for analytical determinations. The major components in the centesimal composition of kurugua seeds were lipids, dietary fiber, and proteins. The oils presented iodine, saponification, and refractive indices characteristic of preferentially polyunsaturated oils. The major component in the fatty acid profile was linolenic acid, an important essential fatty acid in the diet. Although the characteristics of kurugua oil, demonstrate its potential application in the food industry as a polyunsaturated oil, source of essential fatty acids, future studies on stability and sensory analysis for food applications are suggested, with great possibilities for the food safety framework.

Liver is recognized as a valuable source of nutrients in human nutrition but there are a few reports of the lipid profile of chicken liver. The aim of work was to determine fat content as well as fatty acids composition of raw chicken liver. The study was carried out on three chicken breeds (New Hampshire, Plymouth Rock, Rhode Island) obtained from National Research Institute of Animal Production in Balice. Total fat was determined by Soxhlet method and the fatty acids profile was performed with gas chromatography method on a Varian 3400. Fat content of chicken liver ranged from 2.65 to 10.07 g/100g depended on the breed. The predominant saturated acid (SFA) in all samples was palmitate (C16:0), followed by stearate (C18:0). Oleate (C18:1) was the major monounsaturated fatty acid (MUFA) in all samples, followed by palmitooleate (16:1). n-3 fatty acids in chicken liver were comparatively lower than SFA and MUFA. The predominant polyunsaturated acid (PUFA) was linoleate (C18:2). Arachidonate (C20:4) was the second most important n-6 fatty acid. Fatty acid content also varied between breeds of chicken. It has been demonstrated that conjugated linoleic acids (CLA) is found in chicken liver.

Abstract Objectives To investigate the fatty acids composition in different lactation stages of human milk in China. Methods A large cross-sectional study was conducted and lactating women (n = 6481) within 0–330 days postpartum were recruited in China between 2011 and 2013. Human milk sub-samples (n = 1135) were randomly selected for fatty acids analysis in the original study. The sample size of colostrum, transitional milk, and mature milk were 160, 177, 798 respectively. Fats were hydrolyzed and fatty acids methyl esters were analyzed using gas chromatography. Results The content of oleic acid, the highest level fatty acid in human milk, was 36.63%, 34.53% and 35.12% of total fatty acids in colostrum, transitional milk, and mature milk, respectively in China. The content of palmitic acid was about 23.69%, 21.90% and 20.82% in colostrum, transitional milk, and mature milk, respectively. Saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids accounted for 36.99%, 39.14% and 23.49% of total fatty acids of mature milk, respectively. The content of linoleic acid and arachidonic acid was 20.47% and 0.54% in mature milk, respectively. The content of eicosapentaenoic acid (EPA) and docosahexenic acid (DHA) was 0.06% and 0.28% in mature milk, respectively. In addition to lactation stage, the fatty acids content differed significantly among various regions, nationalities, or mode of delivery. (i.e., Regions (city vs rural): oleic acid: 33.8% vs 36.4%; linoleic acid: 22.88% vs 17.21%; arachidonic acid:0.64%vs 0.59%; DHA: 0.42% vs 0.26%; EPA: 0.09% vs 0.04%. Nationality (Han vs Minority): oleic acid: 34.40% vs 36.59%; linoleic acid: 21.69% vs 16.54%; arachidonic acid:0.64%vs 0.57%; DHA: 0.38% vs 0.24%; EPA: 0.08% vs 0.04%.). Conclusions Oleic acid is the most abundant fatty acids in human milk of China. In addition to lactation stage, the fatty acid concentrations vary among different regions and nationalities in China. Funding Sources This study was supported by Beijing Natural Science Foundation (S160002), the National Key R&D Program of China (2017YFD0400601) and the National High Technology Research and Development Program of China (863 Program) (2010AA023004).

Polyunsaturated fatty acids (PUFAs) comprise about 35-40% of the total lipid content from green algaeChlorella, reaching up to 24% linoleic acid and 27% α-linolenic acid inC. vulgaris. Also, microalgae nutrient composition may be modulated by changes in the culture medium, increasing fatty acid and microelement concentrations in the algae biomass. PUFAs, such as α-linolenic (n-3) and linoleic (n-6) acids, as well as its derivatives, are considered essential for dietary consumption, and their ability to regulate body chemistry has been recently explored in depth. A balanced fatty acid consumption is shown to counteract the negative effects of western diets, such as chronic inflammation and glucose intolerance. In this brief commentary, technological and practical uses ofC. vulgarisare explored as means to improve dietary quality and, ultimately, human health.

The objective of this study was to determine the chemical composition, fatty acid profile, and values of healthy indices of milk from a specialized farm of Polish Coldblood mares of different ages, birth orders, and lactation stages. Milk samples (n = 48) were collected for analysis in weeks 10, 15, and 25 of lactation from mares aged between five and 14 years. The study showed that the stage of lactation has a significant effect on the fatty acid (FA) profile of the milk produced on the farm. The highest concentration of monounsaturated and polyunsaturated FAs was found in milk produced from the 15th week of lactation. The milk was also characterized by low values of atherogenic and thrombogenic indices, which indicate the health benefits of milk with respect to the content of fatty acids and their potential to prevent or cause atherosclerosis and thrombosis. The study also found a significant correlation between the number of foalings (birth order), the fatty acid profile, and atherogenic index of milk produced on the farm. The findings from the study indicate that it is possible to modify the fatty acid profile of bulk tank milk through appropriate management of the age structure of the herd of mares. To confirm this dependence, the study will be continued on a larger group of mares.

The species Astrocaryum aculeatum (Arecaceae) is known in the Brazilian Amazon as tucumã, whose fruit is much appreciated by the population of the region, where its pulp, oleaginous, is the most consumed. Thus, the aim of this work was to perform a profile of fatty acids by GC-FID and minerals by ICP-OES of the oil of the pulp of the tucumã (A. aculeatum), as well as their physicochemical properties by 1H NMR. The fruits were collected in Alto Alegre city, Roraima, Brazil. These were taken to the laboratory, sanitized and removing your pulp, submitted to the oven with air circulation at 50 °C for 72 h, the dried pulps were milled and sieved between 20-40 mesh. The pulp oil extraction was realized in Soxhlet with hexane for 6 hours (yield of 54.7%). Were identified a total of 10 fatty acids, of these 23.8% are saturated fatty acids and 76.2% are unsaturated fatty acids: palmitic acid (10.4%), stearic acid (4.9%), oleic acid (64.2%), linoleic acid (11%) and linolenic acid (1%). The physicochemical properties have a pulp oil acid index of 0.31 mg KOH g-1, saponification of 190.39 mg KOH g-1, iodine index of 85.97 mg g-1. Minerals such as in their available forms K (70.05 mg L-1) Na (30.30 mg L-1), Ca (20.13 mg L-1) and P (20.07 mg L-1) were observed in high concentrations. The Amazon tucumã is an oleaginous that deserves our attention because it is composed of essential fatty acids that are beneficial to the human health.
