During the shelf-life, meat undergoes a number of processes that negatively affect the quality of the product, including fatty acid composition. The application of various plant extracts in meat could affect the changes of fatty acids during storage. Thus, the aim of this study was to investigate the effect of various spice and herb extracts on fatty acid composition in raw pork, beef, and chicken meat when stored at 4 °C for 13 days. Based on multivariate statistical analysis, two datasets were extracted from each type of meat. One dataset included samples with allspice, bay leaf, black seed, cardamom, caraway, clove, and nutmeg with the high share of total MUFA (monounsaturated fatty acids) in chicken and pork meat and high MUFA and PUFA (polyunsaturated fatty acids) contribution in beef meat after storage. The second dataset included basil, garlic, onion, oregano, rosemary, and thyme with high PUFA share in chicken and pork meat and high SFA (saturated fatty acids) contribution in beef meat. From the regression analysis, a significant effect of time on fatty acid composition in meat was reported. Generally, the rates of fatty acid changes were dependent on the plant extract incorporated into the meat. The most visible effect of plant extracts was obtained in chicken meat. In chicken meat with plant extracts, the rates of SFA and PUFA changes with time were slower compared to the control sample. In summary, the fatty acid composition of intramuscular fat varied during storage, and the addition of plant extracts significantly affected the rate of these changes, which was dependent on the meat matrix.

Degree Of Satisfaction

The article presents the results of research on the development of the technology of biscuits using non-traditional plant raw materials. In the course of the work, the replacement of a part of the premium wheat flour in the dairy crust recipe with a mixture of rice (17%) and sesame (11%) and the replacement of butter with camelina butter in an amount of 5% by weight of the product was justified. It was found that the introduction of functional raw materials gives the products a moderately sweet milk taste with a pleasant nutty aftertaste and orange color. The resulting products are characterized by a balanced fatty acid composition of ω-3 and ω-6, enriched with minerals and vitamins. Calculation of the nutritional value showed that the consumption of 100 g of the developed biscuits covers the daily need of an adult for polyunsaturated fatty acids of the ω-3 and ω-6 families by 37–75% and 19,4–31,5, respectively. The protein content rises by 1,5 times, and the carbohydrate content decreases by 1,16 times. At the same time, the degree of satisfaction of the daily requirement for potassium increases – by 2,3%, in calcium – by 7–7,5%, in phosphorus – by 12,6%, in magnesium – by 16,3%, in iron – by 7,3–13,3%. The degree of satisfaction of the daily requirement for vitamins B1 also increases – by 19,7–20,9%, B2 – by 2,2–2,3%, PP – by 8,1–9,3%, E – by 1,6–1,7% compared to the control sample of dairy cakes. The developed products can be recommended for preventive nutrition, people adhering to a healthy lifestyle, as well as school-age children, pregnant and lactating women who have a deficiency of ω-3 and ω-6 fatty acids in the diet

Flavour Perception

The polyunsaturated fatty acids (PUFA) of the intramuscular phospholipids are the most significant lipids in the development of cooked beef flavour (Mottram and Edwards, 1983). In lamb, differences in n-6 and n-3 fatty acid composition have been shown to be a major factor influencing consumer perception and acceptability (Sañudo et al, 2000). Altering meat PUFA, especially n-3 fatty acids, to improve its value in human nutrition (COMA, 1994) may have effects on flavour and acceptability. The aim of this work was to evaluate differences in flavour perception when intramuscular fatty acid composition is changed in beef meat.

The article presents the results of the study on fatty acids content of broiler chickens purchased from retailers and broiler chickens grown in organic farming. In the study we compared the obtained results. There are also results of the influence of developed preventive drug postbiotic on the fatty acid composition of broiler chickens. The samples were compared in terms of their nutritional value and quality. Chicken that goes into the retail network is obtained from broiler chickens grown in a traditional (intensive) technological way. Organic poultry is extensive. For the experiment in organic farming, we formed the 2 groups (control and experiment). In the experimental group, broiler chickens received a prophylactic preparation - a postbiotic with organic feed, and no drugs were used in the control. In-depth studies of the mechanisms of its effect on the body of chickens and the quality of the products obtained were studied changes in the fatty acid composition of total lipids in skeletal muscle and the biochemical composition of the muscle tissue of chickens. There were no significant changes in the fatty acid content of the tested meat compared with the control group. The content of palmitoleic, linoleic and caprylic acids is slightly increased. The fat content of heavy broiler chickens is much higher than that of broiler chickens. The best fatty acid ratio of omega-3 and omega-6 is found in organic chicken meat. Retail chicken meat has a lower omega 6 content, significantly higher than palmitic acid omega 3. Organic chicken meat contains 3-5% less fat compared to retail chicken. In the meat of chickens grown using organic technology, the amount of saturated fatty acids increased significantly by 11.13%, there is a significant decrease in omega-6 fatty acids by 7.57% and an increase in the amount of omega-3 fatty acids by 0.8% compared to with chicken from the retail chain. Therefore, the value of organic chicken meat lies not only in the absence of residues of antibiotic substances, pesticides and herbicides, but also in its biological value and dietary properties.

Dietary Polyunsaturated Fatty Acids

Nutrition has a major impact on the fatty acid composition of beef, despite high levels of biohydrogenation of dietary polyunsaturated fatty acids (PUFA) in the rumen (Scollan et al., 2006). The latter may be ameliorated by feeding rumen-protected lipid. Grass relative to concentrate feeding results in beef characterised by a higher content of n-3 PUFA and excellent colour shelf life. This study investigated the effects of including a PUFA-rich lucerne-based plant extract (PX) on the fatty acid composition and meat quality in beef.

Flax Oil

The creation of new types of dairy products for functional purposes with the addition of unconventional oils as sources of polyunsaturated fatty acids (PUFA) is a promising and relevant research sphere. The study aimed to investigate the fatty acid composition of experimental samples of curd spread with different content of flax oil. The fatty acid composition was determined on a Hewlett Packard HP-6890 chromatograph with a flame ionization detector equipped with a 100 m long SP-2560 capillary column. It is established, that the total content of saturated fatty acids in curd spread containing 8 %, 10 %, and 12 % of flax oil was reduced, and the general total content of unsaturated fatty acids increased accordingly by 5.73 %, 6.94 % and 7.31 %, compared to the control sample without flax oil. The gas-chromatographic analysis showed that flax oil is rich in omega-3 PUFA due to its high content of α-linoleic acid, so adding flax oil to the spread led to an increase in its content of α-linolenic acid and, accordingly, increased the content of PUFA of the omega-3 family. Thus, adding 8 %, 10 % and 12 % of flax oil to the curd spread, the content of α-linolenic acid in it increased accordingly by 3.91 %, 4.52 %, and 4.69 %, compared to the control sample. Curd spread with 10 % content of flaxseed oil is characterized by the most optimal fatty acid composition. The ratio of saturated fatty acids to unsaturated in this curd spread is 1.9 : 1, and the ratio between PUFAs of the omega-3,-6, and -9 families are 1.3 : 1: 5.3.

Poultry Meat

Enriching chicken meat with long chain n-3 polyunsaturated fatty acids (LC n-3 PUFA) is a viable means of increasing population intakes (minimum recommended 450 mg/d, SACN, 2004) of these essential fatty acids. Feeding broilers fish oil to achieve this causes problems with taint in the meat, whereas feeding an oil rich in C18:3 n-3 (LNA) does not result in the deposition of LC n-3 PUFA (Rymer and Givens, 2006). Stearidonic acid (C18:4n-3) is further down the conversion pathway of LNA to LC n-3 PUFA and appears to be converted much more efficiently by humans to LC n-3 PUFA than LNA (James et al., 2003). Feeding birds an oil rich in C18:4n-3 may therefore result in more enrichment of poultry meat with n-3 PUFA other than LNA, without the taint associated with feeding fish oil. The objective of this experiment was to determine what the effects on meat fatty acid composition and sensory characteristics were when broilers were fed an oil (SDA) derived from soyabean genetically modified to produce high concentrations of C18:4 n-3.

Induced Aggregation

SummaryPlatelet aggregation and its relation to fatty acid composition of platelets, plasma and adipose tissue was determined in 196 randomly selected, free-living, 40-49-year-old men in two regions of Finland (east and southwest) with a nearly twofold difference in the IHD rate.There were no significant east-southwest differences in platelet aggregation induced with ADP, thrombin or epinephrine. ADP-induced platelet secondary aggregation showed significant negative associations with all C20-C22 ω3-fatty acids in platelets (r = -0.26 - -0.40) and with the platelet 20: 5ω3/20: 4ω 6 and ω3/ ω6 ratios, but significant positive correlations with the contents of 18:2 in adipose tissue (r = 0.20) and plasma triglycerides (TG) (r = 0.29). Epinephrine-induced aggregation correlated negatively with 20: 5ω 3 in plasma cholesteryl esters (CE) (r = -0.23) and TG (r = -0.29), and positively with the total percentage of saturated fatty acids in platelets (r = 0.33), but had no significant correlations with any of the ω6-fatty acids. Thrombin-induced aggregation correlated negatively with the ω3/6ω ratio in adipose tissue (r = -0.25) and the 20: 3ω6/20: 4ω 6 ratio in plasma CE (r = -0.27) and free fatty acids (FFA) (r = -0.23), and positively with adipose tissue 18:2 (r = 0.23) and 20:4ω6 (r = 0.22) in plasma phospholipids (PL).The percentages of prostanoid precursors in platelet lipids, i. e. 20: 3ω 6, 20: 4ω 6 and 20 :5ω 3, correlated best with the same fatty acids in plasma CE (r = 0.32 - 0.77) and PL (r = 0.28 - 0.74). Platelet 20: 5ω 3 had highly significant negative correlations with the percentage of 18:2 in adipose tissue and all plasma lipid fractions (r = -0.35 - -0.44).These results suggest that, among a free-living population, relatively small changes in the fatty acid composition of plasma and platelets may be reflected in significant differences in platelet aggregation, and that an increase in linoleate-rich vegetable fat in the diet may not affect platelet function favourably unless it is accompanied by an adequate supply of ω3 fatty acids.

Soybean is a valuable protein and oilseed crop ranked among the most significant of the major crops. Field experiments were carried out in 2016–2019 in South-East Poland. The influence of soybean cultivars (Aldana, Annushka), nitrogen fertilizer (0, 30, 60 kg∙ha−1 N) and inoculation with B. japonicum (control, HiStick® Soy, Nitragina) on the content of fatty acids (FA) in soybean seeds was investigated in a three-factorial experiment. This study confirms the genetic determinants of fatty acid composition in soybean seeds and their differential accumulation levels for C16:0, C16:1, C18:1n9, C18:2, C18:3, and C20:0 as well saturated (SFA), monounsaturated (MUFA), and polyunsaturated (PUFA) fatty acids. Increasing the rate from 30 to 60 kg ha−1 N did not produce the expected changes, suggesting the use of only a “starter” rate of 30 kg ha−1 N. Inoculation of soybean seeds with a strain of Bradyrhizobium japonicum (HiStick® Soy, BASF, Littlehampton, UK and Nitragina, Institute of Soil Science and Plant Cultivation–State Research Institute, Puławy, Poland) is recommended as it will cause a decrease in SFA and C16:0 acid levels. This is considered nutritionally beneficial as its contribution to total fatty acids determines the hypercholesterolemic index, and it is the third most accumulated fatty acid in soybean seeds. The interaction of cultivars and inoculation formulation on fatty acid content of soybean seeds was demonstrated. An increase in the value of C16:0 content resulted in a decrease in the accumulation of C18:1, C18:2, and C18:3 acids. The content of each decreased by almost one unit for every 1% increase in C16:0 content. The dominant effect of weather conditions on the FA profile and C18:2n6/C18:3n3 ratio was demonstrated. This suggests a need for further evaluation of the genetic progress of soybean cultivars with respect to fatty acid composition and content under varying habitat conditions.
