This article describes the use of Chlorella sorokiniana biomass additives in pasta recipes to enrich the product with biologically active phytonutrients, as well as to achieve the desired color range without the use of synthetic dyes. Samples of dry biomass were obtained by the cultivation of microalgae C. sorokiniana (strain), its quality indicators and nutritional value were determined for use as a food additive. A method of using dry biomass of microalgae C. sorokiniana as a phytoadditive to replace 5% of flour mixture for effective enrichment of pasta with biologically active phytonutrients was proposed. The choice of the optimal amount of addition of microalgae biomass was proved since it turned out that the replacement of flour should be no more than 5% due to the distinct fish flavor of the final product. The present study was conducted to evaluate the effect of adding dry biomass of Chlorella microalgae on total protein, lipid, chlorophyll, and carotenoid content. Substitution of 5% of pasta flour led to an increase in the content of proteins and lipids to 15.7 ± 0.50% and 4.1 ± 0.06%, respectively. Meanwhile, the addition of microalgae Chlorella to pasta has helped to increase the content of polyunsaturated fatty acids, chlorophyll, and carotenoids which are necessary for the prevention of foodborne diseases. The aim of this study is to develop pasta recipe with additives of microalgae biomass C. sorokiniana and study their quality indicators.

(1) Background: Arthrospira (commonly known as Spirulina) is an edible cyanobacterium that is produced worldwide as a food supplement owing to its high nutritional value. Arthrospira displays strong potential as an important ingredient in the development of novel functional foods. Polysaccharides from Arthrospira are biologically active compounds and hence there is interest in producing biomass rich in carbohydrates. (2) Methods: A. platensis was cultivated under different degrees of phosphorus limitation in order to trigger the accumulation of carbohydrates. The biomass was then characterized in terms of its content of α- and β-glucans, total dietary fiber and monosaccharide profile. Fourier-transform infrared spectroscopy (FTIR) was used for the rapid analysis of the main biomass components. (3) Results: Phosphorus limitation resulted in an increase in carbohydrates (from 23% up to 65% dry biomass) of which 4–12% (in relation to the dry biomass) was α-glucans and 20–34% was 1.3:1.6 β-glucans, while 1.4:1.6 β-glucans were not detected. Total dietary fibers ranged from 20–32% (of dry biomass), whereas among the carbohydrates, the predominant monosaccharide was glucose (>95%). FTIR performed well when applied as a prediction tool for the main biomass components. (4) Conclusions: Since β-glucans are of particular interest as biologically active compounds, this study demonstrates that phosphorus-limited A. platensis could be a potential ingredient for the development of novel functional foods.

The aim of the study was to assess the nutritional value of H. tuberosus tubers grown in the organic farming system in Poland and Lithuania. The work was based on field experiments carried out in 2015–2017 in Parczew (Poland) and Akademija (Lithuania). The experiments were carried out using the randomized block method in four replications. Two cultivars of Jerusalem artichoke (JA) ‘Albik’ and ‘Rubik’ were tested. After the harvest of tubers, an assessment of their quality was carried out by standard methods. Due to the relocation of JA cultivation from Central and Eastern Europe to Northeast Europe, there were changes in the chemical composition of H. tuberosus tubers. The tubers from crops in Lithuania were characterized by a lower content of inulin, crude fiber and protein, ascorbic acid, total and endogenous amino acids than in Poland, but a higher content of true protein and macroelements. Edaphic factors determined, to a greater extent than genetic factors, the nutritional value of tubers. Assessment of the influence of varietal characteristics, meteorological conditions, and geographic location on the amount of biologically active compounds in JA will allow growers and consumers to choose the most suitable cultivars.

Проведена сравнительная оценка хлебопекарных смесей (ХПС) Ливенка и Амарантус, включающих биоактивированное зерно пшеницы и ржи и биоактивированные злаковые культуры и амарантовую муку соответственно, и хлеба на их основе. Исследованы химический состав, биологическая и энергетическая ценность ХПС и выпеченных на их основе образцов зернового хлеба Ливенский и Амарантус. Установлено, что ХПС Амарантус и хлеб Амарантус отличаются несколько большим содержанием белка, кальция, лизина по сравнению с ХПС Ливенка и хлебом Ливенский. Однако по количеству пищевых волокон и витаминов ХПС с амарантовой мукой и изделия на ее основе несколько уступают образцам, приготовленным без добавки амарантовой муки. Внесение амарантовой муки в дозировке 5,5% взамен части ржаной муки незначительно повышает энергетическую и биологическую ценность ХПС и хлеба на ее основе. Установлено, что ХПС Ливенка и Амарантус относятся к функциональным пищевым ингредиентам за счет содержания значимого количества биологически активных веществ, а изделия на их основе – к функциональным пищевым продуктам. Comparative evaluation of baking mixes (BM) of Livenka and Amarantus, including bioactivated grains of wheat and rye and bioactivated cereals and amaranth flour, respectively, and bread on their basis was carried out. Chemical composition, biological and energy value of BM and baked on their basis samples of grain bread Livenskiy and Amarantus were investigated. It is established that the BM Amarantus and bread Amarantus are slightly high content of protein, calcium, lysine, compared with BM Livenka and bread Livenskiy. However, the number of dietary fibers and vitamins BM with amaranth flour and products on it based are concede to samples a little prepared without the addition of amaranth flour. The introduction of amaranth flour in a dosage of 5,5% instead of a portion of rye flour slightly increases the energy and biological value of BM and bread on it based. It was found that the BM Livenka and Amarantus are functional food ingredients due to the content of a significant amount of biologically active substances, and products on their based – to functional foods.

Water-scarce areas are continually increasing worldwide. This factor reduces the quantity and quality of crops produced in affected areas. Physical seed treatments are considered economical and ecofriendly solutions for such problems. It was hypothesized that a moderately drought-tolerant crop grown from seeds treated with a He-Ne laser utilizes water-limited conditions better than plants grown from untreated seeds. A field study was conducted, growing a moderately drought tolerant crop (sunflower) with supportive seed treatment (He-Ne laser treatment at 300 mJ) for 0, 1, 2, and 3 min. Thirty-day-old plants were subjected to two irrigation conditions: 100% (normal) and 50% (water stress). Harvesting was done at flowering (60-day-old plants) at full maturity. The sunflowers maintained growth and yield under water limitation with a reduced achene number. At 50%, irrigation, there was a reduction in chlorophyll a, a+b and a/b; catalase activity; soluble sugars; and anthocyanin, alongside elevated proline. The improved chlorophyll a, a+b and a/b; metabolisable energy; nutritional value; and yield in the plants grown from He-Ne-laser-treated seeds support our hypothesis. Seeds with 2-min exposure to a He-Ne laser performed best regarding leaf area; leaf number; leaf biomass; chlorophyll a, a+b and a/b; per cent oil yield; 50-achene weight; achene weight per plant; carotenoid content; and total soluble phenolic compound content. Thereafter, the leaves from the best performing level of treatment (2 min) were subjected to high-performance-liquid-chromatography-based phenolic profiling and gas-chromatography-based fatty acid profiling of the oil yield. The He-Ne laser treatment led to the accumulation of nutraceutical phenolic compounds and improved the unsaturated-to-saturated fatty acid ratio of the oil. In conclusion, 2-min He-Ne laser seed treatment could be the best strategy to improve the yield and nutritional value of sunflowers grown in water-limited areas.

Introduction. Functional foods help to improve the diet, maintain health, and prolong active longevity. Therefore, food science constantly develops new formulations of functional products. Caramel can hardly be called healthy food as it possesses low nutritional and high energy value. Moreover, caramel contains easily digested sugars but no physiologically functional ingredients, e.g. vitamins, minerals, etc. In order to increase the nutritional value of caramel, we fortified the traditional formulation with ascorbic acid and Valetek-3 vitamin premix. Study objets and methods. The research featured laboratory and pilot samples of caramel. The quality indicators of the finished product were determined according to the industry standards. Results and discussion. The research provided advanced formulations and technology for the development of the new functional caramel fortified with ascorbic acid and a vitamin complex. A set of experiments resulted in a nomenclature of regulated quality indicators and functional properties. The changes in the quality of the caramel during storage made it possible to define the shelf-life of the product. Conclusion. The research defined the optimal formulation for the new kind of functional caramel and determined its quality indicators. The present article introduces a list of quality standards for caramel fortified with vitamin C (ascorbic acid) and Vitalek-3 vitamin premix, as well as the indicators of its functional properties. The research provided the new functional food with the regulatory and technical documentation necessary for its mass production.

Представлена информация по изучению технологических особенностей культивирования нового для российского продовольственного грибного рынка вида дереворазрушающего гриба – шиитаке (Lentinus edodes (Berk.) Sin). Шиитаке – один из наиболее перспективных для промышленного культивирования видов съедобных грибов, обладающих лечебными свойствами, занимает второе место в мировом производстве съедобных грибов. Работа по поиску материалов, используемых в качестве добавок к основному исходному материалу субстрата и способствующих созданию благоприятного водно-воздушного и кислотного режима, повышению питательности приготовленного субстрата, ускорению процесса вегетативного роста мицелия в субстрате, актуальна для грибоводческой практики. Цель исследований – разработать технологический процесс полного цикла культивирования шиитаке и установить его оптимальные параметры в производственных условиях ООО «Апрель». Исследования, испытания и разработку технологии полного цикла выращивания шиитаке проводили в лаборатории грибоводства ВНИИО – филиале ФГБНУ ФНЦО и на базе действующего предприятия по выращиванию дереворазрушающих грибов ООО «Апрель» с 2019 по 2020 год. Технология приготовления субстрата и выращивание плодовых тел шиитаке аналогична технологии производства вешенки. Изучено влияние состава субстрата на урожайность шиитаке в вариантах: 1. Опилки дуба (80%) + опилки березы (10%) + минеральные добавки (10%); 2. Опилки дуба (80%) + опилки березы (5%) + лузга семян подсолнечника, отруби пшеничные (5%) + минеральные добавки (10%). Использован штамм шиитаке 0912. В результате апробации разработанного технологического процесса полного цикла культивирования шиитаке в производственных условиях было установлено, что оптимальная продолжительность периода выращивания шиитаке и получение урожая в камерах выращивания составляет в среднем 53–68 суток. Важнейшая составляющая технологического процесса культивирования шиитаке – приготовление субстрата, подбор исходных материалов и биологически активных добавок, обеспечивающих его высокую питательность (содержание общего азота – 0,8–1,2% и более) и возможность получения урожая более 30–35% от массы субстрата с высокой экономической эффективностью от 290% (рентабельность производства). The article presents information on the study of technological features of cultivation of a new type of wood-destroying mushroom – shiitake (Lentinus edodes(Berk.) Sin), which is new for the Russian food mushroom market. Shiitake – one of the most promising types of edible mushrooms for industrial cultivation, which have medicinal properties, occupies the second place in the world production of edible mushrooms. The work on the search for materials used as additives to the main source material of the substrate and contributing to the creation of a favorable water-air and acid regime, increasing the nutritional value of the prepared substrate, accelerating the process of vegetative growth of mycelium in the substrate is relevant for mushroom growing practice. The purpose of the research – to develop the technological process of the full cycle of shiitake cultivation and to establish its optimal parameters in the production conditions of LLC April. Research, testing and development of the technology of the full cycle of shiitake cultivation were carried out in the laboratory of mushroom growing of ARRIVG – branch of Federal Scientific Centre of Vegetable Growing and on the basis of the existing enterprise for growing wood-destroying mushrooms LLC April from 2019 to 2020. The technology of preparing the substrate and growing shiitake fruit bodies is similar to the technology of producing oyster mushrooms. The influence of the substrate composition on the shiitake yield in the variants was studied: 1. Oak sawdust (80%) + birch sawdust (10%) + mineral additives (10%); 2. Oak sawdust (80%) + birch sawdust (5%) + sunflower seed husk, wheat bran (5%) + mineral additives (10%). The shiitake 0912 strain was used. As a result of testing the developed technological process of the full cycle of shiitake cultivation in production conditions, it was found that the optimal duration of the shiitake growing period and the harvest in the growing chambers is on average 53–68 days. The most important component of the technological process of shiitake cultivation is the preparation of the substrate, the selection of raw materials and biologically active additives that ensure its high nutritional value (total nitrogen content of 0.8–1.2% or more) and the possibility of obtaining a crop of more than 30–35% of the substrate weight with high economic efficiency of 290% (profitability of production).

In this paper, it is proposed to use the biomass of microalgae Chlorella sorokiniana as a biosorbent for wastewater treatment, as well as an oral sorbent. Biosorbents are capable of adsorbing both organic and inorganic compounds, including heavy metals. The sorption capacity depends on the type of aquatic plant and microalgae strain. The use of microalgae and aquatic plants as biosorbents for pollutant treatments is discussed in the introduction part. The biomass of microalgae Chlorella sorokiniana was chosen as the object of this study. The cultivation conditions (temperature, light, pH and aeration) and the optimal biomass harvesting parameters are presented. Dehydration of biomass was carried out in two ways: IR-drying and freeze-drying. The obtained samples were tested for the ability of the biomass to extract heavy metal ions (zinc, cadmium, zinc, copper) from standard solutions. The initial concentration of heavy metal ions in the working solutions was 10 mg/l. Results show that the lyophilized samples demonstrated up to 99.9% of heavy metal removal efficiency. The paper also presents the composition of Chlorella sorokiniana biomass, in which up to 40.97–41.87% are proteins. The analysis of the amino-acid composition showed a ratio of essential to non-essential amino-acids higher than 0.8. All the above results confirm the possibility of using microalgae biomass as an oral sorbent and as an additive in the production of functional foods.
