Walnut (Juglans regia L.) is the oldest fruit grown in the world and grows spontaneously almost throughout Romania. In this study, the physical properties and chemical composition of twenty types of walnuts from three different locations in Romania were studied. The physical analyzes that were performed were: walnut dimensions and shape properties (nut diameter, nut length, nut shape and nut size), fruit properties (walnut weight, walnut kernel weight and percentage of kernel) and external properties of walnut (walnut kernel extraction, kernel color and shell roughness). The proximate chemical composition (content of water, ash, lipids, proteins and carbohydrates) was determined by standardized AOAC methods, while fatty compounds were determined by GSMS. Water content ranged from 1.23% to 5.00%, mineral content between 1.31% and 2.49%, lipids content between 56.09% and 66.56% and protein content ranged between 12.73% and 20.413%. Based on these, the carbohydrate content and nutritional value of the 20 walnut samples were calculated. In all samples, saturated palmitic acid (C16:0) and stearic acid (C18:0) as well as unsaturated oleic (C18:1), linoleic (C18:2) and linolenic (C18:3) fatty acids were determined. A statistical analysis was also performed correlating the results obtained from the chemical analyzes of the walnuts.

Proximate Chemical Composition

Although game meat quality has been under the spotlight in numerous studies, the quality of brown bear (Ursus arctos) meat is still unknown. The aim of this study was to determine the effects of sex and age on the proximate chemical composition, fatty acid profile, and lipid indices of brown bear meat. Nine (n = 9) females and nine (n = 9) males were hunted during the Croatian spring hunting period in 2018. Based on age, bears were divided into two groups: <3 years (n = 9; five females and four males) and 4–6 years (n = 9; four females and five males). For analysis purposes, samples of M.semimembranosus were collected. Age was shown to have an effect on the traits analyzed, while sex-related differences were not found. Brown bear meat has a high fat content (average 6.12%), especially in older bears (~9%). The contents of protein, dry matter, and ash were similar to those of other game species. Monounsaturated fatty acids made up approximately 50% of all fatty acids, with the most abundant being C18:1n-9. More favorable profiles of essential polyunsaturated fatty acids were found in younger bears. The ratio of polyunsaturated and saturated fatty acids was closer to the recommended ratio than the ratio of n-6 and n-3 polyunsaturated fatty acids, and lipid indices were favorable. Further research is needed to determine seasonal changes in brown bear meat quality.

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.

AbstractBark on trees protects the plant against environmentally adverse conditions as well as fungi and insect attacks. There are different chemical substances, mostly in the outer bark of trees, which can stop fungi from developing. Bark as a by-product of wood plantations is available in high quantity and can serve as an excellent source for the production of eco-fungicides. In the presented article, bark of various poplar clones from two short-rotation coppices (SRC) in Poland and Germany was examined to determine the chemical composition, the possible extraction of potential fungicides (terpenes, aromatic and phenolic substances), and influence of their extracts on slowing the growth of mold fungi. It was proved that the content of the fungicidal substances depends strongly on the clone type. Two methods of extraction—Soxhlet and batch—were compared to obtain fungicidal extracts. Fungicidal substances were found in extracts gained with both approaches. Triterpenes, fatty acids, aldehydes, and alcohols were primarily the active fungicides in the Soxhlet extracts, whereas phenolic substances act as fungicides in the batch extracts.

ABSTRACT: This study evaluated the yield, color, and chemical composition of commercial cuts (tail, sirloin cut, back fillet, and thigh) of Pantanal caiman meat in both sexes. The yield of tail was higher than other cuts, and the yield of females (17.0%) was higher than males (15.9%). The thigh of males had lower protein content (20.8%) compared with other cuts. Females showed a higher lipid content in the tail (2.4%) and thigh (0.8%) compared with males (1.7% and 0.4%, respectively). The tail presented the greatest content of monounsaturated fatty acids (45.2%) and higher n6/n3 ratio (4.6). Although lightness was not different among cuts or between sexes, there were differences in color. Males have more yellowish meat compared with females. Thigh and back fillet were more reddish when compared to sirloin cut and tail, regardless of sex. In conclusion, female tail meat provided greater yield and lipid content than males, and this result was statistically significant. These findings can help producers and consumers alike, better understand yield, quality, and nutritional quality of Pantanal caiman meat.

Lamb Meat

In the present study, the evaluation of the carcasses and meat quality, in terms of chemical composition and fatty acid profile, of lambs from five autochthonous sheep breeds (Altamurana, Bagnolese, Gentile di Puglia, Laticauda, and Leccese) reared in continental Southern Italy, were studied. All the carcasses were evaluated according to the EU Mediterranean classification system for carcasses weighing less than 13 kg. Meat chemical composition and fatty acids profile were assessed on both loin and leg commercial cuts. Fatty acid composition of loin resulted in differences among breeds, displaying lower values of saturated fatty acid in Altamurana, Bagnolese, and Leccese breeds and the highest content of polyunsaturated fatty acid in the Altamurana breed. Principal component analysis grouped lamb according to fatty acid content and to conjugated linoleic acid (CLA), omega n-3 and n-6 fatty acids; thus, Altamurana, Bagnolese, and Leccese breeds are characterized by the highest values of CLA content. Our data demonstrated that lamb meat from autochthonous breed has good carcass quality and the content of CLA, n-3, and n-6 was valuable for human consumption; therefore, the valorisation of local meat quality can help to avoid the extinction of the autochthonous breed offering to the market and consumer’s high nutritive products.

Lecithins are widely used in the food industry as food additives. In this regard, the requirements for the lecithins quality are quite high, and the development of the rapid determination methods of their quality indicators, including the acid value, is an urgent task. The article presents research of the peculiarities of vegetable lecithins chemical composition for the development of a method for determining their acid value using the pulsed nuclear magnetic relaxation (NMR) method. It was found that the studied lecithins differ significantly in the content of individual phospholipid groups exhibiting acidic properties. As a result of the research of the fatty acid composition of the lecithins acetone-soluble fractions, it was found that the highest total content of monounsaturated fatty acids is a characteristic of sunflower oleic type lecithins (81.3 %) and rapeseed lecithins (66.3 %), and polyunsaturated fatty acids – sunflower linoleic type lecithins (63.6 %) and soybean lecithins (67.7 %). Researches of the NMR characteristics of lecithins with the introduction of carbon tetrachloride (CCl4) have been carried out. It was found that the redistribution of component composition in the “lecithin-CCl4” system occurs at different ratios for each type of lecithin, which is due to their chemical composition peculiarities.
