Therapeutic Value

Interest in the production and sale of goat milk products has been growing over the past 20 years. The chemical composition of goat milk, which greatly affects its nutritional and therapeutic value, makes its products more acceptable to consumers. The aim of this study was to compare the chemical composition and fatty acid profile of Alpine and Saanen goat milk. The results showed that there were differences in certain chemical components between the milk of these two breeds. Protein, fat and ash content in Alpine goat milk was 4.53 g/100 g, 4.65 g/100 g and 0.94 g/100 g, respectively, and these values were higher than in Saanen goat milk (3.64 g/100 g, 3.20 g/100 g and 0.88 g/100 g, respectively). Differences in the fatty acid profile were also observed. Despite being kept under different breeding regimes, no statistically significant differences were observed in the total saturated fatty acids (SFA) or polyunsaturated fatty acids (PUFA) between breeds. Although there was no difference in total SFA content, there was less palmitic acid (C16:0), as the predominant fatty acid in goat milk, in Alpine (26.94 g/100 g of fat) than in Saanen goat milk (28.60 g/100 g of fat). Unlike SFA and PUFA content, differences were observed in total monounsaturated fatty acids (MUFA), with 22.8 g/100 g of fat in Alpine goat milk and 24.0 g/100 g of fat in Saanen goat milk. Based on these findings, it can be concluded that the implemented breeding regimes in different geographical areas with different pasture, together with genetic factors of breeds, greatly affect the goat milk chemical composition and fatty acid profile.

ABSTRACT: Vegetable oils have been used to substitute pork backfat to improve the fatty acid profile of fermented sausages. The aim of this study was to assess the chemical composition, microbiological properties, and fatty acid profile of Italian-type salami with pork backfat substituted (15% and 30%) by emulsified canola oil. Fat contents decreased while moisture contents increased in Italian-type salami with emulsified canola oil. The growth of lactic acid bacteria in salami was not affected by canola oil and absence of fecal coliforms, coagulase-positive staphylococci, and Salmonella were reported during processing of fermented sausages. Lower levels of saturated fatty acids (SAFAs), higher levels of monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (PUFAs) were observed in salami with emulsified canola oil. Together, our results indicated that substituting pork backfat with emulsified canola oil improved the nutritional values of Italian-type salami.

Aberdeen Angus (AA), Charolais (CH), Simmental (SI), and Hereford (HE) bulls were used in two fattening experiments with the objective of determining breed differences in chemical composition, sensory characteristics, and fatty acid profile of m. longissimus thoracis et lumborum. The target slaughter live weights were set at 550 kg for earlier maturing breeds AA and HE and 630 kg for later maturing breeds CH and SI. Intramuscular lipid contents were higher in AA and HE (P < 0.05) than in CH and SI, but cholesterol contents were similar among the breed groups. The highest content of dry matter was found in HE (P < 0.05), while AA had the lowest protein content (P < 0.001). Meat from AA generally received the highest scores for different sensory characteristics (odour, flavour, texture, and juiciness). Concentrations of stearic acid (C18:0) in total muscle lipids were lower in SI than in CH (P < 0.05), while total saturated fatty acids were lower in SI compared to CH (P < 0.001) and AA (P < 0.05). CH had less oleic acid (C18:1-n9c) and total monounsaturated fatty acids than AA (P < 0.05), SI and HE (P < 0.01). Concentrations of linolenic acid (C18:3-n3) were highest in AA (P < 0.01).

The aim of this research was to determine fatty acid profiles in piglet brain, skin, and muscle, and in the milk of sows fed fat with different saturation grades during gestation and lactation. At 42 days of gestation, 50 multiparous sows were randomly allocated to one of two treatments, namely a diet containing pork lard (n = 25) and a diet containing soybean oil (n = 25). The fats were provided at 3.6% during gestation and at 4% during lactation. The experimental diets were offered through the weaning of the piglets. The fatty acid profile of the milk was determined fourteen days after parturition. At weaning (21 days postpartum) and seven days later, one of the piglets (n = 64) from 16 sows allocated to each treatment was selected at random to determine fatty acid profiles in brain, skin and muscle. Saturated and monounsaturated fatty acids were higher in the diet with pork lard than in that with soybean oil, in which the polyunsaturated fat content was higher. A higher saturation of fatty acids was found in milk from the sows that consumed pork lard, which contained more saturated fatty acids than the milk from sows that consumed soybean oil. The fatty acid profiles in muscle and skin of the piglets were affected by the diet of the sows. However, the fatty acid profile of the piglets’ brains was not affected by the diet of their mothers.

Fatty acid profile and the related nutritional indices of the breast, thigh and drumstick muscles were studied at three farms, suppliers of ROSS 308 line of broilers, slaughtered at the age of 42 days. The proximate chemical composition of the commercial slaughter cuts revealed contents between 16.26�22.78% for proteins and 1.80�7.45% for total lipids, the breast having the highest protein and ash content and lowest values for fat and moisture. The obtained values were mainly affected by region (P[0.001). Meat fatty acid profile was affected (P[0.001) by commercial slaughter regions (CSR) and by the interactions between CSR and supplier farms (Farm A, B, and C) at different levels. The obvious findings highlighted that Farm B supplied broilers with a delivered higher content of beneficial fatty acids (LA, LNA, AA, EPA, and DHA) in breasts and drumstick, while for thigh, Farm C had the best results. The content of total saturated fatty acids (SFAs), monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (MUFAs) had the highest level in the thigh (P[0.001).

Abstract: The objective of this work was to evaluate the chemical composition and fatty acid profile of milk from F1 Holstein/Zebu cows in different lactation periods, when receiving different levels of dietary supply in percentage of body weight. Sixty cows were evaluated, with five levels of dietary supply and three lactation periods. The levels of dietary supply had no effect on the production of milk corrected to 3.5% fat (12.25 kg per day). There was also no effect of dietary supply levels, in the different lactation periods, on contents of fat (3.34%), protein (3.41%), lactose (4.60%), total solids (12.0%), defatted dry extract (8.80%), and urinary nitrogen (14.5 mg dL-1), nor on somatic cell count (89.98 mL-1). As the dietary supply level was reduced, the sum of saturated fatty acids in milk was decreased in up to 9.15% and that of monounsaturated fatty acids was increased in up to 25.28%. Feed restriction does not alter the chemical composition of milk, but improves its quality of fat by reducing saturated fatty acid content, increasing the concentration of monounsaturated and desirable fatty acids in up to 54%, and increasing the hypo- and hypercholesterolemic fatty acid ratio in up to 168.97%.

The Impact

Abstract The impact of different amounts of concentrate and stage of lactation on fatty acid profile in milk fat was measured in 30 lactating Nubian goats. The ration included medium-quality hay, grazed pasture and concentrate feed (mashed barley, oats and beet pulp at 1:1:1 wet weight ratios). Half of the goats (group A) received 1.2 kg whereas group B received 1.0 kg of concentrate daily. Milk samples were taken 3 times during lactation. The total amounts of saturated fatty acids (SFA) increased gradually during lactation while polyunsaturated (PUFA) and monounsaturated fatty acids (MUFA) decreased. Group A had lower SFA but higher concentrations of MUFAs and PUFAs at all 3 samplings. Nubian goats fed more concentrate had FA ratios presumably more suitable for consumers of milk and milk products.

The aim of this work was to set the quality standards of the chistorra de Navarra, a raw-cured Spanish traditional meat product, through the study of its sensory and physicochemical features. The quality of chistorra samples, coming from 50 different artisan producers, were assessed during three sessions by expert assessors (n = 15). In the first session, instrumental colour (L*, a*, and b*) and appearance and odour parameters were evaluated in the raw products. In the second session, texture and flavour attributes were determined in cooked products. Finally, in the third session, the best 10 classified chistorras from the first and second sessions were sensorially evaluated and sampled for further analysis: texture (Warner Bratzler and texture profile analysis (TPA)), chemical composition, and fatty acid profile. The chistorras with the highest sensory scores had high shear force values, flavour intensity, and fat/hydroxyproline ratio. The average fatty acid profile obtained for chistorra de Navarra was: 42% saturated fatty acids (SFA), 45% monounsaturated fatty acids (MUFA), and 13% polyunsaturated fatty acids (PUFA), which was similar to the one found in other raw-cured sausages. Considering the sensory evaluation, chistorra was defined as a product with an intense orange colour, and with high resistance value in the initial bite. It was also characterised by a high juiciness and tenderness, aroma, and meat flavour. In mouth, the pork fat, one of the ingredients of chistorra, was balanced without any of the ingredients dominating. Chemically, the chistorra was characterised by a fat content close to 67% (dry matter), low hydroxyproline occurrence (≤0.6), and protein amount ranging 18–38%.

Spices and herbs are well-known for being rich in healthy bioactive metabolites. In recent years, interest in the fatty acid composition of different foods has greatly increased. Thus, the present study was designed to characterize the fatty acid composition of 34 widely used spices and herbs. Utilizing gas chromatography (GC) flame ionization detection (FID) and GC mass spectrometry (MS), we identified and quantified 18 fatty acids. This showed a significant variation among the studied spices and herbs. In general, oleic and linoleic acid dominate in seed spices, whereas palmitic, stearic, oleic, linoleic, and α-linolenic acids are the major constituents of herbs. Among the studied spices and herbs, the ratio of n−6/n−3 polyunsaturated fatty acids (PUFAs) was recorded to be in the range of 0.36 (oregano) to 85.99 (cumin), whereas the ratio of PUFAs/saturated fatty acids (SFAs) ranged from 0.17 (nutmeg) to 4.90 (cumin). Cumin, coriander, fennel, and dill seeds represent the healthiest fatty acid profile, based upon fat quality indices such as the ratio of hypocholesterolemic/hypercholesterolemic (h/H) fatty acids, the atherogenic index (AI), and the thrombogenic index (TI). All these seed spices belong to the Apiaceae family of plants, which are an exceptionally rich source of monounsaturated fatty acids (MUFAs) in the form of petroselinic acid (C18:1n12), with a very small amount of SFAs.
