AbstractEdible insects constitute a potential source of alternative proteins as a food supplement. The present study aimed to investigate the chemical composition, energy and nutritional values, the digestibility and functional properties of Carbula marginella (Thunberg) and Cirina butyrospermi (Vuillet) defatted flour, protein concentrates, and isolates. Carbula marginella has shown the highest content of protein (41.44%), lipid (51.92%), calcium (33.92 mg/100 g) and sodium (185.84 mg/100 g) while the highest contents of carbohydrate (34.54%), ash (4.77%), iron (31.27 mg/100 g), magnesium (150.09 mg/100 g), and potassium (1277 mg/100 g) have been observed for C. butyrospermi. Linoleic (30.23%), palmitic (27.54%), oleic (26.41%) and stearic (8.90%) acids were the most dominant fatty acids found in C. marginella. Cirina butyrospermi was characterized by high levels of oleic (27.01%), stearic (21.02%), linolenic (20.42%), palmitic (13.06%), and linoleic (8.01%) acids. Protein and essential amino acid contents of the protein isolates in both insect species were 1.7–2 times higher than that of their defatted flours. The protein isolate of C. marginella exhibited the highest protein digestibility (87.63%), while the highest fat absorption capacity (8.84 g/g) and foaming capacity (48.40%) have been obtained from the protein isolate of C. butyrospermi. These findings indicate that the protein concentrates and isolates of C. marginella and C. butyrospermi have great potential for industrial applications.

Under conditions of digital economy, in particular, agriculture and food industry, specialized food products, including biologically active food supplements produced from natural raw materials, are increasingly used to improve nutrition and health, and to maintain quality of life. These products are affordable and efficient in coping with metabolism disorders caused by different diseases. Taking all these factors into account the authors developed a pant-based food supplement aimed at improving metabolism of people with type 2 diabetes. The composition of this specialized product is scientifically based in terms of its ingredients and their active substances biochemical and synergetic properties. The innovative production technology of this biologically active food supplement involves pressing its main ingredients and auxiliary substances into tablets. The tablet form provides accurate dosage, convenient packaging and storage, reliable film coating, which ensures tablet hardness and protection from aggressive exposure. The food supplement properties have been determined, including its nutritional value and functional properties. One tablet includes: ascorbic acid – 8.6 mg, chromium -0.1mg, zinc – 2.3 mg, flavonoids – 10mg, tannins – 20 mg, manganese – 0.8mg. Clinical trials proved the supplement efficacy and functional properties. People with type 2 diabetes took 1 tablet of phyto-complex twice a day alongside sugar-lowering drugs. After one month they demonstrated lower levels of blood glucose, total cholesterol and triglycerides as well as better overall health and lower body mass index. The obtained data clearly indicate better pancreas functions, improved microcirculation, carbohydrate and fat metabolism normalizing. The article also provides recommendations of the supplement intake for people with type 2 diabetes and glucose tolerance disorders.

В статье приведены результаты исследования влияния сроков хранения на микробиологические показатели безопасности и степень проявления функциональных свойств растительной пищевой добавки «Порошок яблочный» (ПД ПЯ). Для проведения исследований на хранение была заложена ПД ПЯ, расфасованная и упакованная в мешки из полипропилена с полиэтиленовыми вкладышами, массой нетто 10 кг. Хранение осуществляли в течение 24 мес. при температуре (20 ± 2)°С и относительной влажности воздуха не более 70%. Установлено, что ПД ПЯ, хранившаяся в течение 18 мес., по микробиологическим показателям безопасности соответствует требованиям ТР ТС 021/2011. Выявлено, что при хранении образца ПД ПЯ в течение 18 мес. потери биологически активных веществ, определяющих ее антиоксидантные и гепатопротекторные свойства, незначительны, %, не более: витамина С 5,0; Р-активных веществ 4,5. В опытах на лабораторных животных установлена высокая эффективность проявления ПД ПЯ, хранившейся в течение 18 мес., антиоксидантных и гепатопротекторных свойств, характеризующихся степенью снижения в сыворотке крови животных продуктов перекисного окисления липидов: малонового диальдегида на 35,6%; диеновых конъюгатов на 32,2%. Установлено также снижение активности ферментов печени аспартатаминотрансферазы и аланинаминотрансферазы на 26,0 и 33,4% соответственно. The article presents the results of the study of the effect of shelf life on microbiological safety indicators and the degree of manifestation of the functional properties of the herbal food supplement Apple Powder (FS AP). For carrying out researches on storage the FS AP packaged and packed in bags from polypropylene with polyethylene inserts, net weight of 10 kg was put. Storage was carried out for 24 months at a temperature (20 ± 2)°Сand relative humidity of air no more than 70%. It has been established that the FS AP stored for 18 months complies with the requirements of TR CU 021/2011 for microbiological safety indicators. It was found that during storage of the FS AP for 18 months, the loss of biologically active substances that determine its antioxidant and hepatoprotective properties are insignificant,%, not more than: vitamin C 5,0; P-active substances 4,5. In experiments on laboratory animals, the high efficiency of the manifestation of the FS AP stored for 18 months, antioxidant and hepatoprotective properties characterized by the degree of reduction in the serum of animal products of lipid peroxidation: malon dialdehyde by 35,6 per cent, diene conjugates by 32,2 per cent.

The secondary raw materials have been studied as sources of pectic substances necessary for the endo-ecological protection of the organism in the globally deteriorating living conditions of modern humans. The article reveals the significance and long-term benefits of such sources of pectic substances as fruit and seed coats, which are obtained in considerable quantities as a secondary raw material during the implementation of the technological process, and often do not find rational use. Research has been carried out on new prospective sources of pectin substances – secondary resources of processing soybean Glycine max (L.) Merrill, sainfoin Onobrýchis arenária, rapeseed Brassica napus L. oleifera, Sarepta mustard Brassica juncea (L.) Czern, and black mustard Brassica nigra (L.) W.D.J. Koch, castor bean Ricinus communis L., sunflower Helianthus annuus L. Fruit and seed coats of these plant species have been studied. The prospects of their secondary resources for pectin production have been shown. The assessment of the quantitative and qualitative characteristics of the pectic substances of the objects under study, as well as their fractional composition and analytical indicators, make it possible to characterize the potential functional, technological and therapeutic properties of pectin preparations. It has been indicated that in the polyuronid component (fraction of galacturonic acid), all the studied samples of surface tissues of soybean, mustard, sainfoin, sunflower, one rape variety meet international requirements for food pectin (52.87–73.22%), and one of them, the pectin from seed coat of the Valenta variety, meets the requirements for pectins for medical purposes (75.83%). Pectic substances of soybean, mustard, castor bean varieties are characterized by a high degree of esterification (62.37–76.88%) in contrast to the varieties of sainfoin and sunflower (45.29–55.15%). According to the degree of esterification, rape varieties are close to low-esterified pectiс substances – 59.34–61.48%. The prospects of using seed and fruit membranes as an unconventional secondary plant raw material to improve the environmental performance of production and to obtain a valuable therapeutic-and-prophylactic food ingredient have been substantiated.

Hemocyanin of the horseshoe crab (Limulus polyphemus) has been studied in nany ways. Recently the structure, dissociation and reassembly was studied using electron microscopy of negatively stained specimens as the method of investigation. Crystallization of the protein proved to be possible and X-ray crystallographic analysis was started. Also fluorescence properties of the hemocyanin after dialysis against Tris-glycine buffer + 0.01 M EDTA pH 8.9 (so called “stripped” hemocyanin) and its fractions II and V were studied, as well as functional properties of the fractions by NMR. Finally the temperature-jump method was used for assaying the oxygen binding of the dissociating molecule and of preparations of isolated subunits. Nevertheless very little is known about the structure of the intact molecule. Schutter et al. suggested that the molecule possibly consists of two halves, combined in a staggered way, the halves themselves consisting of four subunits arranged in a square.
