Jatropha spp. plants are used in traditional medicine, food and for the elaboration of biofuel. The Tehuacán-Cuicatlán Biosphere Reserve in México holds genetic richness and endemism for this genus, but the specific use of the plants and the seed chemical profiles are still unknown. The objectives of this research were to record the traditional forms of use of Jatropha species, and to analyze the chemical composition of Jatropha spp. seeds. For this, a semi-structured survey was conducted in 15 towns, and 20 interviews were applied in each one between May and August 2012. Data allowed to estimate the Significant Use Level and Relative Use Value per species. Besides, seeds from J. neopauciflora, J. rufescens, and J. rzedowskii were collected between August and October 2013, and to seed flour samples we determined total lipids by the Soxhlet method, crude protein by the Kjendahl method, and ashes according to AOAC methods; fatty acid profile and phorbol esters were determined by gas chromatography and by HPLC, respectively. We recorded that the species J. neopauciflora, J. oaxacana, J. rufescens, J. ciliata, and J. rzedowskii, are used as traditional medicine, food, and ornaments, except for J. ciliata, for which none use was recorded. The Significant Use Level as food was found not significant, but for medicinal purposes, J. neopauciflora obtained the highest Relative Use Value (9.0 %). The latex is used to treat 13 disorders, including dental problems (toothache, sensitivity, caries), oral diseases (oral herpes, gingivitis, and oral candidiasis) with a Significant Use Level of 32.9 %; it is also used as a hemostatic. The protein content among species varied from 23.37 to 26.06 %, and total lipids from 34.79 to 36.60 %. The principal unsaturated fatty acids were oleic (25.08 to 30.09 %) and linoleic (44.55 to 48.46 %), and the saturated fatty acids were palmitic (10.11 to 16.50 %) and stearic (9.47 to 11.15 %). Phorbol esters, the main cause of seed’s toxicity, were absent in J. neopauciflora, J. rufescens, and J. rzedowskii. In conclusion, the Significant Use Level of Jatropha species studied was low, with little cultural acceptance and sporadic utilization. The Relative Use Value was important for medicinal purposes, especially for J. neopauciflora. The dehulled seeds of J. neopauciflora, J. rufescens, and J. rzedowskii are potentially useful as food, having high protein contents, and unsaturated oleic and linoleic fatty acids. With this study we report three non-toxic Jatropha species and recommend to scientifically validate the antimycotic use of J. neopauciflora latex.

In this article the chemical composition of 2 types of animal fats (cow milk fat and poultry fat) following the variation of saturated and unsaturated fatty acids proportion during freezing storage was studied. Determination of chemical composition of animal fats is important in establishing organoleptic and physico-chemical parameters, the variation of them in time, nature and proportion of fatty acids conferring specific characteristics to them. For milk fat was determined the following chemical composition: saturated fatty acids 68.35%, monounsaturated fatty acids 29.25%, polyunsaturated fatty acids 2.4%. After 4 months of storage under freezing there was a change in fatty acids proportion, saturated fatty acid content increased to 70.41%, monounsaturated fatty acids content decreased to 28.23%, and polyunsaturated fatty acids content decreased to 1.35% due to oxidation process when decreased the degree of unsaturation due to unsaturated fatty acids oxidation. In the case of poultry fat there was also an increase of saturated fatty acids (30.71%) and a decrease for monounsaturated (43.47%) and polyunsaturated (24.81%) fatty acids content.

Pig Carcasses

The chemical composition of pig backfat determines its physical properties of firmness and cohesiveness as well as its nutritional value. The firmness of the tissue depends upon its content of saturated fatty acids, particularly stearic, which make it harder; and unsaturated fatty acids, particularly linoleic, which make it softer. Cohesiveness depends upon the connective tissue and fat content and the compositon of these; soft fat and low cohesiveness frequently being found together. Nutritional value may be judged by the energy content of the tissue, which increases in proportion to its lipid content, or by the ratio of polyunsaturated fatty acids to saturated fatty acids (P:S ratio), used by COMA to indicate the desirability of the fat as a risk factor for cardiovascular disease. There is evidence that as fatness has been reduced in British pigs, composition has changed with consequences for these characteristics.

Alternative protein sources are gaining increasing global attention as a solution to address future protein demands. Determining the chemical composition of meat alternatives is vital to confirm that it is nutritious, but also to increase product value and promote its utilization. The carcass characteristics and chemical composition of springhare, an underutilized protein source, was found to be comparable to that of commercially reared rabbits. Hence, its introduction into the commercial supply chain would likely not offset consumers accustomed to purchasing rabbit/hare meat. Springhare meat had a high protein content (~22.5 g/100 g meat) and low lipid (<1.3 g/100 g meat) content. The meat’s fatty acids mainly comprised C18:2n6c (γ-linoleic acid; 24%), C18:0 (stearic acid; 20%), C16:0 (palmitic acid; 19%), C20:4n6 (arachidonic acid; 15%) and C18:1n9c (oleic acid; 13%). Although sex did not significantly influence the carcass characteristics and meat composition, season did have an effect (p < 0.05) on the fatty acid profile. The meat harvested in summer had higher (p < 0.05) concentrations of favorable unsaturated fatty acids, C18:2n6c, C18:3n6, C18:3n3 (α-linolenic acid), C20:2n6 (eicosadienoic acid), C20:3n3 (eicosatrienoic acid), compared to the meat obtained in winter, which contained more (p < 0.05) saturated fatty acids. The results verify that springhare can be utilized as a viable alternative protein source.

The Impact

The aim of this study was to evaluate the chemical composition of the back fat tissue of mangalitsa pig and meaty pig breeds and their crosses, and the pigs that were fed with feed that was enriched or unenriched with oil, from the aspect of the production of biodiesel, where the starting material for the fuel would be the fat tissue of pigs. By examining the impact of breed and oil content in feed, it was found that chemical parameters (fat, water, protein, saturated and unsaturated fatty acids) show statistically significant variation under the influence of these factors. The highest fat content (89.39%), which is essential for conversion of fat into biodiesel, was found in back adipose tissue of mangalitsa breed, while the lowest fat content (86.10%) was found in the back fat tissue of meaty breeds and their crosses. Favorable ratio of saturated to unsaturated fatty acids (37.92% : 62.07%), on which some physical properties of the fuel depend, was found in the back fat tissue of pigs that were fed with feed enriched with oil, and the largest proportion of saturated fatty acids, i.e. the most unfavorable fatty acid composition (40.90% : 59.09%) was found in the back fat tissues of pigs that were fed with feed unenriched with oil. The lowest content of saturated fatty acids and water (7.44%), as the key factors that determine the cetane number of the fuel and the fuel production process, indicates that the most suitable raw material for the production of biodiesel is the fat tissue of pigs that were fed with food that contained a certain amount of oil.

The seeds of the almond tree [(Prunus dulcis (Mill.) D. A. Webb. (syn. Prunus amygdalus)] were collected in two different periods of maturity and were studied for their lipid content. The total lipids (TL) were extracted by the Bligh-Dyer method and the lipid classes have been isolated by chromatographic techniques and were analyzed by HPTLC coupled with a flame ionization detector (HPTLC/FID) and GC-MS. The oils were found to be rich in neutral lipids (89.9% and 96.3% of total lipids) and low in polar lipids (10.1% and 3.7% of total lipids) for the immature and mature seed oils, respectively. The neutral lipid fraction consisted mainly of triacylglycerides whereas the polar lipids mainly consisted of phospholipids. GC-MS data showed that the main fatty acid for both oils was 9-octadecenoic acid (oleic acid). The unsaturated fatty acids were found as high as 89.4% and 89.7%, while the percentage of the saturated fatty acids was found 10.6% and 10.3% for the immature and mature seed oils, respectively. Liposomes were prepared from the isolated phospholipids using the thin lipid film methodology, and their physical properties were characterized. Cytotoxicity was found absent when assayed against normal and cancerous cell lines. These new formulations may have future applications for encapsulation and delivery of drugs and cosmetically active ingredients.

Fat mixtures containing 10, 30, 60, and 70% saturated fatty acids as glycerides were fed to male rats at a level of 17% by weight of a chow diet. The saturated acids were mainly palmitic rather than lauric and myristic as previously used. In confirmation of earlier results the fat mixture containing 30% saturated fatty acids produced the greatest weight gains and the highest food efficiency. The same trend was noted when similar fat mixtures were added to a purified diet but differences in weight gain and food efficiency were not significant. The source of fatty acids had no effect on weight gains. The excretion of total lipids was not influenced by the degree of saturation of the fats within the limits studied. Shortening, however, caused increased excretion of total lipid. There were no significant differences in liver and adrenal weights produced by these diets.

Crude palm oil (CPO) was extracted from fresh fruit bunches of RYL7 oil palm cultivated in Hainan by using a self-made single stage screw press. The physicochemical characteristics and Fatty acid composition of the CPO was investigated. The experimental results included melting point (33.10 °C), density (0.91 g/cm3 at 20 °C), acid value (8.35 mg KOH/g), iodine value (62.72 mg iodine/g), saponifiable value (198.02 mg KOH/g), moisture and volatile matter (0.16% of total lipids), insoluble impurities (0.04% of total lipids), unsaponifiable matter (0.40% of total lipids). Oleic acid (40.90% of total fatty acids), palmitic acid (37.88% of total fatty acids), linoleic (14.29% of total fatty acids), followed by stearic acid (5.11% of total fatty acids) were found to be the predominant fatty acids in the oil. The unsaturated oleic acid was the most predominant fatty acid in CPO of Hainan while saturated palmitic acid was the most principal fatty acid in palm oil from Malaysia. The contents of linolenic, unsaturated fatty acids, and polyunsaturated fatty acids in this CPO were 4.09%, 5.09%, 4.09% higher than that of Malaysia, respectively. In addition, the percentages of palmitic acid and saturated fatty acids of this oil were 5.62%, 6.01% lower than that of Malaysia, respectively.

This article presents material on the study of the efficiency of raising Edilbayev sheep using a new feed supplement and assesses its effect on increasing the meat productivity of animals and improving mutton indices. To do this, we at Volgograd-Edilbay SGC LLC selected 30 animals of the Edilbayev breed of 7 months of age in two experimental groups according to the principle of pair-analogues with 15 animals each. The rams who received the standard diet were included in the control group, and their analogues, which were introduced a new feed additive in the diet, were included in the experimental group. The duration of the experiment was 105 days. In this case, the preparatory period of the experiment is 10 days, the transitional period is 5 days, the main one is 90 days. As a result of the experiment, it was found that at the end of the experiment, the rams of the experimental group exceeded their counterparts in the control group in live weight by 2.9 kg, or 5.72% (P≥0.999). As a result of the control slaughter, it was established that by the pre-slaughter mass, the rams of the experimental group are 1.65 kg or 3.35% more than analogues of the control group (P≥0.95); weight of fat tail fat - by 0.35 kg, or 13.21%; slaughter mass - by 1.49 kg, or 5.23% (P≥0.99); slaughter yield - by 1.09%, respectively. A study of the chemical composition of lamb showed that in the content of the rams of the experimental group in the meat, iodine was 0.08 μg / g more than the analogues of the control group (P≥0.95); silicon - at 3.92 μg / g; selenium - at 0.12 μg / g (P≥0.99); zinc - at 6.0 μg / g, respectively. According to the content of fatty acids, tail fat obtained from animals of the control and experimental groups differs in favor of the experimental group. Saturated fatty acids in turkey fat of animals from the experimental group contain 61.34%, which is 3.22% higher in comparison with the control group. Unsaturated fatty acids in animals of the experimental group contain 38.66%, which is 3.17% less in comparison with the control group. Thus, the highest results in meat productivity, chemical composition, and the amount of saturated and unsaturated acids were obtained from edilbaevsky rams that received a new feed supplement.

To evaluate the addition of 3% of C.A.N.O.L.A. oil, corn oil and soybean oil to the diets on the chemical composition of rabbits meat, 100 animals were slaughtered, among them 20 with 35 days old and 40 animals with 50 and 70 days old. The slaughtered animals with 35 days old were from broods whose mothers, since the birth received the same experimental diets evaluated after 70 days old. After the slaughter, the right leg meat of each animal was collected and, in each group, receiving the respective experimental diets, were grouped in three composed samples to posterior chemical analysis. The experimental design was in factorial scheme 4x3 (four diets versus three ages) with three replication and 36 analyzed samples. The fatty acids profile deposited in the meat reflects the composition in the experimental diet. The oil addition to the diets, independent of the source decreased the saturated fatty acids level and increased the unsaturated fatty acids in the rabbits meat with the age advance. Particularly, the diet with C.A.N.O.L.A. oil provided the meat with higher monounsaturated fatty acids level and ?3 and lower ?6, resulting in the lower ?6: ?3 ratio.
