This work aimed to analyze the physicochemical properties of cellulose from OPT used in the fabrication of CMF and evaluate the efficacy of the hydrogel CMF as an encapsulant for L. fermentum InaCC B1295 stored at room temperature and in the refrigerator. The Kjeldahl method was used to evaluate the protein content; the gravimetric method was used to determine OPT's ash, moisture, and fiber contents; the Soxhlet method was used to determine the fat content carbohydrates were computed using the difference method. The levels of holocellulose, lignin, and cellulose were also determined. Viability, acid and bile resistance of strain B1295 were evaluated at various temperatures for 35 days. The most abundant component of OPT fiber was cellulose, followed by hemicellulose and lignin. XRD examination revealed that OPT cellulose has a crystal index of 83.40%. FTIR analysis was used to detect the stretching vibrations of the –OH group on cellulose at 3419.03 cm-1. CMF hydrogel from OPT sustained L. fermentum InaCC B1295 survival for up to 28 days at room and refrigerated temperatures. At acidic conditions and in the presence of bile, the viability of L. fermentum InaCC B1295 was excellent, with a drop in cell population of less than 0.2 log CFU/g over 35 days at room and refrigerated temperatures. CMF obtained from OPT can be used as an encapsulant to maintain viability, acid resistance and bile of probiotics. There is still a need for research into the usage of CMF from OPT in combination with other encapsulants to extend the storage life of L. fermentum InaCC B1295. Doi: 10.28991/ESJ-2022-06-01-08 Full Text: PDF

Длительное время мы наблюдали снижение численности населения, происходящее во многих странах постсоветского пространства, которое говорит о кризисе в состоянии здоровья человека и населения страны в целом. К сожалению, это является причиной высокой смертности среди населения разного возраста, низкой продолжительности жизни, высокого порога заболеваемости. Все это одна из составляющих качества жизни населения страны, а именно общественного здоровья, которое напрямую характеризует национальную безопасность. Одной из первопричин наблюдаемой проблемы является дефицит пищевого белка, что находит отражение не только в экономической, но и в социальной составляющей нашей страны и всего мира в целом. Результаты проведенных многочисленных исследований сходятся в том, что в сутки человек должен потреблять 1-2 г белка на 1 кг веса тела, в зависимости от деятельности. Значение белка в рационе питания современного человека невозможно переоценить. Ведь развитие и сохранение мышц зависят от количества белка в потребляемых продуктах, так как он является так называемым строительным материалом для формирования клеток, что в свою очередь влияет на обмен веществ в организме. Достаточное содержание белка позволяет сократить процесс восстановления организма после болезней. Большое количество белка в продуктах позволяет повысить эффективность применяемых диет для похудения. Кроме того, белок является одним из основных источников незаменимых аминокислот. Белоксодержащие продукты включаются в рацион человека как носители белка и как продукты функционального назначения, которые придают пище привлекательность и характеризуются высокой пищевой ценностью и органолептическими показателями качества. For a long time, we have seen a decline in the population occurring in many countries of the post-Soviet space, which speaks of a crisis in the state of health of the person and the population of the country as a whole. Unfortunately, this is the cause of high mortality among the population of different ages, low life expectancy, and a high morbidity threshold. All this is one of the components of the quality of life of the population of the country, namely public health, which entails a threat to national security. One of the root causes of the observed problem is food protein deficiency. This is reflected not only in the economic component of our country and the whole world, but also in the social one. The results of numerous studies agree that a person should consume 1-2 g per 1 kg of body weight per day, depending on the activity. The importance of protein in the diet of modern humans cannot be overestimated. After all, the development and preservation of muscles depend on the amount of protein in the products consumed, as it serves as a building material in the process of cell development and metabolism in the body. Sufficient protein content allows you to reduce the process of recovery from diseases. A large amount of protein in foods allows you to increase the effectiveness of the diets used for weight loss. In addition, the protein is one of the main sources of essential amino acids. Protein-containing products are used not only as carriers of protein, but also as functional products that give food attractiveness and are characterized by high nutritional value and organoleptic quality indicators.

Определяющей целью солодоращения является повышение ферментативной активности зерна. Нами предлагается способ интенсификации солодоращения пшеницы посредством применения неорганического стимулятора роста «Энерген». В исследовании использовали пшеницу Алтайской селекции трех сортов: «Алтайская 100», «Дуэт» и «Алейская». Предложенный неорганический препарат вносили при замачивании в последнюю замочную воду в количестве 0,6 г/дм и выдерживали с ним в контакте пшеницу в течение 6 ч. За данный период в ферментативной системе обработанного зерна произошли более выраженные изменения в сравнении с контрольным вариантом (необработанным зерном). К концу замачивания уровень активности ферментов опытных образцов стал выше уровня аналогичных активностей ферментов контрольных вариантов на 11,8 и 9,9 % соответственно для амилолитической и протеолитической активностей. Последующее проращивание зерна повысило ферментативную активность пшеничного солода. По окончании 7 сут данной стадии прирост амилолитической активности над активностями необработанного зерна для разных сортов составил от 31,5 до 59,0 %, протеолитической - от 97,8 до 125,4 %. При этом отмечено маловыраженное отличие показателей амилолитической и протеолитической активностей проращиваемого обработанного пшеничного солода шестых и седьмых суток ращения, что позволяет сократить продолжительность данной стадии и всего производства солода на одни сутки. Готовый пшеничный солод отличался высокой ферментативной активностью (в диапазоне для трех сортов): амилолитическая - 344,9-360,8 ед./г, протеолитическая - 324,9-257,8 ед./г, более низкой в сравнении с контрольным вариантом продолжительностью осахаривания - от 18 до 20 мин. Кроме этого, предложенный способ солодоращения позволяет использовать пшеницу с высоким содержанием белка, как, например, сорт «Алейская» с массовой долей белка 14,6 %, поскольку в процессе проращивания под стимулирующим действием неорганического препарата «Энерген» процесс протеолиза протекает более интенсивно, и в конечном солоде содержание белка снижается до 10,4 %. The defining goal of malting is to increase the enzymatic activity of grain. We propose a method for intensifying the malting of wheat through the use of an inorganic growth stimulator «Energen». The study used wheat of the Altai selection of three varieties: «Altai 100», «Duet» and «Aleyskaya». The proposed inorganic preparation was introduced during soaking into the last soak water in an amount of 0.6 g/dm and wheat was kept in contact with it for 6 hours. During this period, more pronounced changes occurred in the enzymatic system of the processed grain in comparison with the control variant (unprocessed grain). By the end of soaking, the enzyme level of the experimental samples is 11.8 and 9.9 % higher than the level of similar enzymes of the control variants, respectively, for amylolytic and proteolytic activities. The subsequent germination of grain increased the enzymatic activity of wheat malt. At the end of seven days of this stage, the increase in amylolytic activity over the activities of unprocessed grain for different varieties ranged of 31.5 to 59.0 %, proteolytic - of 97.8 to 125.4 %. At the same time, there was a little pronounced difference in the indicators of amylolytic and proteolytic activities of the germinated processed wheat malt of the sixth and seventh days of fermentation, which makes it possible to shorten the duration of this stage and the entire malt production by one day. The finished wheat malt was characterized by high enzymatic activity (in the range for three varieties): amylolytic 344.9-360.8 units /g, proteolytic 324.9-257.8 units/g, lower duration of saccharification in comparison with the control variant of 18 to 20 minutes. In addition, the proposed method of malting allows the use of wheat with a high protein content, such as the Aleyskaya variety with a mass fraction of protein of 14.6 %, since during germination under the stimulating effect of the inorganic preparation Energen, the proteolysis process proceeds more intensively, and in the final malt the protein content decreases to 10.4 %.

A pot experiment was carried out in the net house of the Department of Soil, Water and Environment, University of Dhaka to evaluate the effectS of different organic manures on the growth performance, biomass production, NPKS content in leaf, stem and root of Burmese grapes (Baccaurea ramiflora) and some chemical properties of post- harvest soil. Two-month old Burmese grapes seedlings were planted in different organic manure-treated soils (viz. ACI, BGF, Bhola, Green Life, Kazi, Modern, Mazim, Payel, Payel Earth, and Shebok). A significant variation was observed among the treatments. Compared to control treatment, application of organic manures exhibited a significant influence on the physiological growth, viz. plant height (30.4 - 34.06 cm), leaf area (64.2 - 71.30 cm2/plant), leaf area index (0.17 - 0.19), fresh weight (32.2 - 53.06 g/plant), and dry weight (22.09 - 41.24 g/plant) after 120 days of the experiment. The highest plant height, leaf area, leaf area index, fresh weight, and dry weight were recorded in Kazi, BGF, Payel and Payel Earth, respectively. Similarly, the concentrations of N, P, K, and S in leaf, stem and root, and their uptakes were found significantly higher than the control. The highest N, P, K and S uptake by leaf, stem and root ranged from 37.66 - 41.69 kg/ha, 0.70 - 0.92 g/ha, 66.19 - 84.926 kg/ha and 6.82 - 10.11 kg/ha, respectively. Protein content was the highest in Payel in leaf (8%) and root (5%), and stem (7%) in Modern manure treatment. The overall results revealed that Kazi and Payel manures might be better for raising strong and healthy Burmese grape seedlings. J. Biodivers. Conserv. Bioresour. Manag. 2021, 7(1): 63-72

The growth kinetics and the lipid and protein content of the microalgal species Chlorella sorokiniana (CS) grown heterotrophically in growth media containing glycerol and increasing amounts of anaerobic digestate (AD) equal to 0%, 15%, 30%, and 50% was studied. The effect of the AD on the fatty acid (FA) distribution of the bio-oil extracted from the CS, as well as on the fatty acid methyl ester (FAME) properties such as the saponification number (SN), the iodine value (IV), the cetane number (CN), and the higher heating value (HHV) was also estimated. The percentage of AD in the growth medium affects the rate of carbon uptake. The maximum carbon uptake rate occurs at about 30% AD. Protein and lipid content ranged from 32.3–38.4% and 18.1–23.1%, respectively. Fatty acid distribution ranged from C10 to C26. In all AD percentages the predominant fatty acids were the medium chain FA C16 to C18 constituting up to about 89% of the total FA at 0% AD and 15% AD and up to about 54% of the total FA at 30% AD and 50% AD. With respect to unsaturation, monounsaturated FA (MUFA) were predominant, up to 56%, while significant percentages, up to about 38%, of saturated FA (SFA) were also produced. The SN, IV, CN, and HHV ranged from 198.5–208.3 mg KOH/g FA, 74.5–93.1 g I/100 g FAME, 52.7–56.1, and 39.7–40.0 MJ/kg, respectively. The results showed that with increasing AD percentage, the CN values tend to increase, while decrease in IV leads to biofuel with better ignition quality.

Purpose: Assessment of the quality of the well-producing groups, the productivity of candidates for the first lactation, the possibility of using genomically estimated cows to increase the parameters of mothers of future bulls, to analyze the quality of the offspring of bulls of various origins.Materials and methods. Research was performed on the basis of breeding plants Karelia Megrega (1455 cows) and Ilinskoe (1200 cows). Analyzed the productivity of bob-producing groups isolated on trivials. 66 Genomically estimated flaws were delivered from Finland after calving for milk productivity for the first lactation with local peers. In assessing the quality of the offspring of producers of different origin, the productivity of 1441 of the daughter of imported bulls and 620 daughters of domestic bulls took place. The degree of differences was assessed by the results of biometric processing of indicators.Results. At the Ilyinskoye dairy farm, the milk yield for lactation of cows of the bull-producing group is 11977 kg of milk with a fat content of 4.33%, protein content of 3.22%. There are 11119 kg of milk at the Megrega farm, 4.42% and 3.23%, respectively. A significant number of individuals (14.7-19.8%) with a milk yield above 9,000 kg of milk, which are a source of replenishment of bull-producing groups, were identified at breeding farms among the first heifers. The possibility of forming and improving the quality of bull-producing groups of cows at the expense of their own livestock is noted, provided that the factors of feeding and keeping animals, increasing the fat content and protein content of milk are optimized.Comparison of productivity indicators of imported "genomic" cows with local peers gave mixed results. At the Ilyinskoye farm, "genomic" cows significantly outperformed subjects of conventional breeding in all indicators: milk yield by 796-903 kg of milk, fat content by 0.27%, protein content by 0.09-0.06%, fat production by 59.4-63.8 kg, protein production by 33.9-34.8 kg, live weight by more thanAt the Megrega farm, in terms of fat content and production, "genomic" individuals also significantly outperformed local peers, and in milk yield and protein content, the differences were unreliable. Genomic evaluation of animals and the involvement of "genomic" cows can contribute to the formation of better groups of mothers of future bulls, especially to solve the most urgent problem of increasing fat and protein milk.Conclusion. In the conditions of large dairy breeding complexes with the technology of loose maintenance, it is advisable to use a system for placing groups of bull mothers in comfortable conditions in special rooms, including individual service.

Abstract Analog rice is artificial rice shaped like rice grains made from non-rice carbohydrate-rich flour with water, which can overcome food security in Indonesia. Taro kimpul is a local food rich in carbohydrates that cannot be widely used. Therefore, kimpul thread has the potential to be used as raw material in the manufacture of analog rice. This study aimed to determine the chemical characteristics of kimpul taro analog rice with dyes and binders. In addition, it is expected to increase consumer acceptance based on sensory testing. This research method uses an experimental laboratory method by making analog rice with 4 formulations. The analysis was water content, ash content, protein content, fat content, carbohydrate content, and sensory (hedonic) analysis, including colour, taste, texture, and overall aroma. The results showed that analog rice A was the best formula selected using the Bayes method based on the results of chemical and hedonic tests. Chemical and sensory characteristics of analog rice A with the use of 4% CMC and 32% beet are as follows moisture 2.88%; ash 2.3%; fat 1.1%; 5.7% protein; carbohydrate 87.94% and a preference value with an average range of neutral-good.

Abstract The purpose of this study was to determine the effect of adding beet juice in fermented goat’s milk using Lactobacillus rhamnosus bacteria on the acidity, syneresis value. This study applied a Complete Randomized Design (RAL) consisting of five treatments Control (P0), 2% of beet juice (P1), 4% of beet juice (P2), 6% of beet juice (P3), and 8% of beet juice (P4) with four repetitions. The data obtained were analysed using ANOVA (Analysis of Variance). If a significant difference is found, then Duncan’s multiple range (DMRT) test is conducted. The results showed that the addition of beet juice with a different percentage in fermented goat milk had significant effect (P<0.05) on syneresis but had a very significantly effect (P<0.01) on the pH value. The addition of 2% of Beet juice resulted in the lowest syneresis value of 9.88%. The low value of syneresis in this study was caused by the addition of beet juice which has high acidity, carbohydrate and protein content. The higher the lactic acid, the lower the pH and the denser the texture formed because the protein’s ability to bind water increases so that the syneresis formed is lower.

Understanding the gravity of nutritional significance of rice (Oryza sativa L.) protein, an experiment conducted in Randomized Complete Block Design (RCBD) involving effect of nitrogen (N) rates i.e.,140 kg N/ha, 120 kg N/ha, 100 kg N/ha and 80 kg N/ha on grain protein content, yield parameters and cooking characteristics of polished rice from eight rice genotypes was conducted. N application significantly affected the grain protein content, grain yield, head rice recovery, plant height and effective tillers. In high protein cultivars substantially low to intermediate amylose content and more cooking time was recorded while in low protein counterpart amylose content was comparatively high with low cooking time. Maximum cooking time in polished rice was of 25 min at 180 kg N/ha dose and highest amylose content of about 27% at 80 kg N/ha. Gumminess and hardness of cooked rice and cooking time significantly elevated with increase in N dose. The substantial differences in grain protein content in brown, polished and cooked rice was observed. Cooking revealed the significant increase in protein content ranged from 50%-70% in low protein to high protein genotypes. R-RGM-ATN-47 with highest grain yield of 62.13 q/ha, grain protein content of 10.00 % in polished rice and intermediate amylose appears to be the most promising candidate.
