The fat migration processes by changing the fatty acid composition of individual parts of glazed sweets with praline-type bodies (based on peanuts) during storage at different temperatures was studied. The main mechanism of mass transfer is considered to be the fat migration through the volume of products through the capillaries. The maximum migration rate of the liquid fat phase is at a storage temperature of 23-25 ° C in samples without transisomers of unsaturated fatty acids. Its reduction is possible with the introduction of 20-30% lauric acid into the fat fraction of products. The crystalline structure of the confectionery fats included in the candy fillings has a significant effect on the migration rate of the liquid fat phase into the glaze. The smallest one corresponded to fats in the β-polymorphic form with an admixture of no more than 3% crystals in the β'-polymorphic form. The specific rate of fat migration has been calculated taking into account the size of a glazed sweets model samples. When in storage temperature increases from 18 to 27 ˚С, it increased 1.7 times. The results of studies of changes in the composition of fatty acids of model samples individual parts of glazed sweets during storage at temperatures of 18 and 27 °C are presented. The proposed approach makes it possible to predict the fat migration processes rate. The comprehensive assessment methodology, which includes the determination of physical and chemical quality indicators during storage, the regularities of fat migration and microbiological changes, will justify the requirements for the technology parameters and the recipe composition of glazed sugary confectionery products with a given expiration date.

Совершенствование процессов модификации масел и жиров при получении жировых полуфабрикатов с оптимальными свойствами кристаллообразования является актуальным для масложирового и кондитерского производств. Существует ограниченное количество природных растительных масел с оптимальным жирнокислотным и триглицеридным составом для применения в качестве основы жировых смесей при производстве кондитерских жировых начинок. Богатые насыщенными жирными кислотами какао-масло и масло ши являются дорогостоящими жировыми компонентами со специфическими свойствами для использования в кондитерских изделиях. Между тем пальмовое масло имеет хороший баланс между насыщенными и ненасыщенными жирными кислотами. С целью снижения себестоимости жировых полуфабрикатов за счет повторной переработки образующихся промежуточных олеиновых фракций пальмового масла и получения жировых полуфабрикатов, имеющих аналогичные средней фракции пальмового масла физико-химические и структурно-механические свойства, проведено комплексное исследование физико-химических свойств и основных показателей плавления и застывания разработанных жировых композиций: температура застывания не более 23,4°C; твердость при 20°C от 43,7 до 44,7%; массовая доля триглицерида POP от 41,4 до 42,7%. Физико-химические характеристики исходных компонентов жировых полуфабрикатов, %, твердость при 20°C: промежуточной олеиновой фракции 32,5; первой стеариновой фракции 74,3; средней фракции пальмового масла 45,6. Температура плавления промежуточной олеиновой фракции 32,8°C. Получены образцы жировых полуфабрикатов для производства кондитерских жировых начинок (индекс кристаллизации от 1,9 до 2,0). Результаты исследования показали возможность создания жировых полуфабрикатов – аналогов средней фракции пальмового масла, имеющих в составе 10% промежуточной олеиновой фракции. Improvement of the processes of modification of oils and fats when obtaining fatty semi-finished products with optimal crystal formation properties is relevant for production fat and oil products and confectionery. There is a limited amount of natural vegetable oils with an optimal fatty acid and triglyceride composition for use as the basis of fatty mixtures in the production of confectionery fat fillings. Rich in saturated fatty acids, cocoa butter and shea butter are expensive fatty components with specific properties for use in confectionery. Meanwhile, palm oil has a good balance between saturated and unsaturated fatty acids. In order to reduce the cost of semi-finished fat products by re-processing the formed intermediate oleic fractions of palm oil and obtaining fat semi-finished products having physicochemical and structural-mechanical properties similar to the middle fraction of palm oil, a comprehensive study of the physicochemical properties and the main indicators of melting and solidification developed fatty compositions: pour point no more than 23,4°C; hardness at 20°Cfrom 43,7 to 44,7%; mass fraction of POP triglyceride from 41,4 to 42,7%. Physical and chemical characteristics of the initial components of fatty semi-finished products, %, hardness at 20°C: intermediate oleic fraction 32,5; first stearic fraction 74,3; middle palm oil fraction 45,6. The melting point of the intermediate oleic fraction is 32,8°C. Samples of fatty semi-finished products for the production of confectionery fatty fillings (crystallization index from 1,9 to 2,0) were obtained. The results of the study showed the possibility of creating fatty semi-finished products – analogues of the mid-fraction of palm oil, which contain 10% of the intermediate oleic fraction.

Abstract Chemical changes that occur in the proteins, nucleotides, and lipids of fish tissue during storage at low temperatures were investigated. Homogenized tissue, prepared from fresh rock-fish (striped hass, Roccus species), was stored up to six days at temperatures from -10° to 4°C and then analyzed. At 0°C and below, the solubility of myofibrillar proteins decreased. There were also changes in polyacrylamide gel electrophoretic patterns of protein extracts. The total nucleotide content decreased rapidly at all temperatures. The lipids were extracted from each sample and separated into neutral lipids, phospholipids, and free fatty acids by column chromatography. The fatty acid composition of each fraction was determined by gas chromatography. In the fresh tissue, polyunsaturated acids occurred in greatest proportion in the free fatty acid and phospholipid fractions, whereas inono-unsaturated acids were inofe highly concentrated in the neutral lipids. The percentages of saturated acids were approximately the same in all fractions. During storage, there were considerably larger losses of individual acids from phospholipids than from neutral lipids. The polyunsaturated acids of the phospholipid fraction were affected most. Over 10% of these aeids were lost in six days at ice temperature, but only a small proportion of the losses was accounted for by increases in free fatty acids. Oxidative proo esses may account for the imbalance because the rate of oxidation, as measured by the thio-barbituric acid test, increased with storage temperature in the same manner as the rale at which unsaturated fatty acids were lost from the pliospliolipuls. Losses of polyunsaturated acids from the neutral lipids were much smaller, suggesting a selectively protective mechanism or environment in that fraction. The changes in the phospholipid fatty acids may provide the basis for useful objective tests of fish lecomposilion.

SummaryDesaturases are enzymes which catalyze desaturation process on carbon chain of fatty acids into unsaturated fatty acids useful for healthy oil. Desaturases could be produced from Absidia corymbifera and applied for increasing unsaturation level and crude palm oil (CPO) quality. Desaturases have been known as very unstable enzymes. The objective this research was to determine carbon sources and culture time for optimum desaturase production, fatty acid composition resulted from desaturase bioconversion, and methods for stabilization of desaturase from A. corymbifera. Results showed that desaturases from A. corymbifera are intracellular enzymes that reached the highest activity in Serrano-Careon medium with C sources of a mixture of sucrose and paraffin (0.14 U/mL) and C sources of molasses (0.11 U/mL) incubated for 76 and 120 hours respectively. Activity of ∆6 and ∆12 desaturases have been detected in culture filtrate of A. corymbifera. Activiy of ∆12 desaturase was confirmed by increasing of linoleic acid in CPO incubated with culture filtrate and biomass extract, while activity of ∆6 was detected by its conversion as much as 66.48 % linoleic acid into gamma linolenic acid (GLA) that having high economic value. Precipitation of culture filtrate and lipid extraction of biomass were unable to stabilize desaturases. Desaturase degradation rate could be inhibited by isolation and washing of microsome fraction using high salt buffer. This method could stabilize desaturases 70-80% from initial activity at storage temperature 25o C and 50 o C for 6 hours. RingkasanDesaturase merupakan enzim yang berperan dalam proses desaturasi rantai karbon asam lemak menjadi asam lemak tak jenuh yang banyak manfaatnya bagi kesehatan. Desaturase dapat dihasilkan dari Absidia corymbifera dan diamplifikasikan untuk peningkatan ketidakjenuhan dan kualitas minyak sawit mentah (CPO). Enzim desaturase dikenal sangat tidak stabil. Penelitian bertujuan menetapkan sumber karbon dan waktu kultur yang memberikan aktivitas desaturase tertinggi, komposisi asam lemak hasil konversi desaturase dan cara menstabilkan desaturase dari A. corymbifera. Hasil penelitian menunjukkan bahwa desaturase dari A. corymbifera merupakan enzim intraselular yang mencapai aktivitas tertinggi pada medium Serrano-Careon dengan sumber karbon campuran sukrosa dan parafin (0,14 U/mL) dan sumber karbon molases (0,11 U/mL) masingmasing pada inkubasi selama 76 dan 120 jam. Aktivitas ∆6 dan ∆12 desaturase terdeteksi pada cairan fermentasi A. corymbifera. Aktivitas ∆12 desaturase terdeteksi dari peningkatan persentase asam linoleat pada CPO yang telah diinkubasi dengan cairan fermentasi atau ekstrak biomassa, sedangkan aktivitas ∆6 desaturase terdeteksi dari dikonversinya sebesar 66,48% asam linoleat menjadi asam gamma linolenat (GLA) yang memiliki potensi nilai ekonomis lebih tinggi. Pengendapan filtrat kultur fermentasi dan ekstraksi lipida biomassa tidak mampu menstabilkan desaturase. Laju degradasi desaturase dapat dihambat dengan cara isolasi dan pencucian fraksi mikrosom dengan bufer garam. Cara tersebut dapat mempertahankan aktivitas desaturase 70–80% pada penyimpanan suhu 25o C dan 50o C selama enam jam.

Abstract The physical and chemical properties and structure of lamb fat are derived from the qualitative composition and content of saturated and unsaturated fatty acids. Higher levels of saturated fatty acid in sheep fat increase the melting point and yield a solid lard. Characteristic fat deposition in the carcass of young sheep is closely related to meat productivity and nutritional value of mutton. The paper presents the results to prove the influence of the genotype of purebred Tsigai rams and their crosses from the Romanov, Texel and Edilbay rams. Crossbred young animals of all genotypes are proved to have an increased content of polyunsaturated fatty acids. The amount of lipids in intramuscular fat in crossbred Romanov rams is 1.68% more, Texel – 13.97% and Edilbay – 21.79%, while the cholesterol content is lower by 1.47%, 6.35% and 5.21%, respectively.

The article is devoted to the study of the properties of bakery products, in particular the choice of the optimal concentration of flaxseed cake in baguettes in order to ensure maximum caloric content. It is known that bakery products are necessary for a person to ensure his health and ability to work. The range of food products, in particular bakery products, is constantly growing. The analysis of the range of bakery products showed that the market is experiencing a shortage of flour products for dietary, therapeutic and prophylactic and special purposes for different groups, and their share in total production does not exceed 1-2%. The problem of food production is becoming more complicated and exacerbated by increasing consumption, declining natural resources of food raw materials and the presence of specific anti-nutrients. The article describes the characteristics of anticancer substances in food, which belong to the groups of hytosterols and lignans. The article presents the results of optimizing the composition and properties of wheat baguettes with the addition of linencake, flaxseed meal. The recipe of bread with the inclusion of linen cake in the amount of 1 to 15% was developed. The nutritionalvalue and caloric content of bread are calculated, its characteristics are given according to the main organoleptic indicators of quality (product surface, color and thickness of the crust, as well as the condition of the crumb). The effect of the percentage of flaxseedmeal on the moisture and acidity of bread samples was studied. It is established that with the increase of the content of flaxseed mealthe protein content increases, the carbohydrate content decreases, the fat content and the amount of unsaturated fatty acids increase.As the content of linen cake in bread increases, the amount of unsaturated fatty acids increases and its caloric content decreases, andits nutritional value increases. The use of flax seeds and products of their processing in the formulation of bakery and confectionery products can increase their biological value and physiological efficiency due to the content of anticancer substances, fibers, micro- and microelements, proteins and essential amino acids. Trial laboratory baking of baguettes showed that the optimal content of linen cake is 5% by weight of wheat flour, which allows you to get bread that meets the standards and does not require changes in technological parameters, which are set for the product without additives.
