Experimental studies of the plant raw material drying processes in the conditions of infrared and microwave fields

The object of research is the process of drying food plant raw materials. Among the existing methods of drying, convective has become the most common in industry, due to its practicality and ease of organization. However, modern convective drying technologies are accompanied by high-energy consumption, which is a serious problem in the conditions of global energy shortage. An analysis of options for solving drying problems proposed by the scientific community was carried out. The paper presents a solution to the problem through the use of electrodynamic dehydration technologies based on directed energy action. The principle of operation of such technologies is that the electromagnetic field directly interacts with polar molecules, which includes water, which leads to a significant increase in the energy efficiency of the drying process and a reduction in its duration. A set of experimental studies aimed at determining the effect of regime parameters, namely specific power, thickness of the product layer and type of edible vegetable raw materials on the drying process under the conditions of infrared and microwave fields, was carried out. The obtained graphic dependences indicate that the treatment of raw materials with ultra-high frequency radiation significantly reduces the time of the drying process and, as a result, is characterized by a low thermal load on the product, which is a significant advantage when processing heat-labile raw materials. This is due to the deeper penetration of the microwave field (up to 30 mm) compared to infrared (up to 0.003 m). In order to determine the effectiveness of innovative equipment, the paper presents the number of energy action, thanks to which a generalization of the experimental data base was carried out. As a result, criterion equations were obtained, which with an accuracy of ±16 % make it possible to calculate drying devices with infrared and microwave energy sources.

Production and use of biomass from waste as part of a sustainable food supply chain

The world population is continuously growing and it affects increased usage of natural resources on one hand and creating waste and endangering natural environment on the other hand. According to FAO estimate in the following decades, the number of people on the earth is going to be increased to 10 billion, which requires increase in food production. The increase is going to lead to larger amount of waste, which is created in food supply chain. The term “food industry waste “covers all substances that represent left overs or unused excessive materials during production process. In fact, all materials that are meant to be disposed of or process them in a suitable way so they do not pollute environment can be considered the waste. The most part of waste from this sector are remains of basic raw materials, which are remains after obtaining main product. Taking into account these substances do not present the main product, they are known as by-products. They can be processed and reused. Non-disposed byproducts from agriculture and food industry pose a threat and endanger the health of people and animals. The interest in using by-products from food supply chain is growing constantly. Experts are looking for additional opportunities for their safe processing, ways for turning them into raw materials, by whose recycling into new products, the amount of the waste would be minimized, and at the same time new, usable products would be introduced. Large amounts of waste, including by-products is generated during production and processing of meat. If animal origin waste is not processed (recycled), it represent lost raw materials for production of protein energy food, technical grease for chemical industry or fuel with high calorific value. The most suitable way for harmless removal of non-edible by-products from meat industry as well as dead animals, is their collection and usage, depending on the structure and kind of raw materials and their categorization, technical processing and application of modern technologies. Disposal of by-products and animal waste in Republika Srpska is not resolved in an appropriate manner and poses a danger to human health and the health ofanimals. In order to achieve this, there is a need for organized collection, storaging and disposal of animal by-products from slaughtering of animals by their technical processing in specialized plants. These plants allow us to produce high-quality animal feed or the raw material for biofuels production (biogas, biodiesel) with the complete protection of the environment. Economic side of this problem implies collection and safe disposal of huge quantities of biological materials that produce costs, which have to be incorporated in prices of the products. If waste of animal origin is not processed (recycled), they represent lost raw material that was possible to incorporate in production of proteinaceous – energetic feed, technical fat for chemical industry or fuels with high calorific value. The most suitability way for harmless removal of inedible by-products from the meat industry, as well as dead animals, is certainly their collection and use depending on the type and structure of raw materials and their categorization, by technical processing using modern equipment and technology.

THE POSSIBILITY OF USING RICE FLOUR FOR THE PRODUCTION OF FUNCTIONAL MEAT PRODUCTS

One of the ways to improve the quality of products and improve the nutrition structure of the population is the introduction of new non-traditional types of plant raw materials into the diet. The created products must contain a balanced complex of proteins, lipids, minerals, vitamins, ballast substances and have high nutritional and taste properties. In Kazakhstan, the possibility of using grain crops as part of meat products is becoming particularly relevant due to their high nutritional value and specific functional and technological properties (FTP).One of the most popular in the world and the second crop in terms of grain production is rice. Rice grains have high FCS and are a dietary product: the protein and fat content in them is much lower than in wheat, rye, buckwheat, corn or soy. Rice protein has a good balance of amino acid composition. Rice grain contains high-grade protein and has a high ability to swell. Rice flour also has a neutral taste, and there is also no fat (unlike soy flour and soy isolate), which allows meat products to retain their characteristic taste after heat treatment. A distinctive feature of rice flour is that it refers to starch-containing (about 80%) raw materials that lack gluten. In this article, its chemical composition and functional and technological properties were studied, the results of the study of samples with different rice flour content were shown. Conclusions on the research work are made.

Life Cycle Assessment of Ti3 C2 Tx MXene Synthesis.

MXenes, two-dimensional transition metal carbides, nitrides, and carbonitrides, have been investigated for diverse applications since theirdiscovery, however, their life cycle analysis (LCA) has not been studied. Here, we perform a "cradle to gate" LCA to assess the cumulative energy demand (CED) and environmental impacts of lab-scale synthesis of Ti3 C2 Tx , the most researched MXene composition. We selected electromagnetic interface (EMI) shielding as it is one of MXenes' most promising applications and compared Ti3 C2 Tx synthesis LCA to aluminum and copper foils, two typical EMI shielding materials. Two laboratory-scale MXene synthesis systems-gram and kilogram batches-were examined. We investigated the CED and environmental implications of Ti3 C2 Tx based on its precursor production, selective etching, delamination processes, laboratory location, energy mix, and raw material type. Our results show that laboratory electricity usage for the synthesis processes accounts for > 70% of the environmental impacts. Manufacturing 1.0kg of industrials-scale aluminum and copper foil releases 23.0kg and 8.75kg of CO2 , respectively, while 1.0kg of lab-scale MXene synthesis released 428.10kg. Chemical usage is less impactful than electricity, which suggests recycled resources and renewable energy can make more sustainable MXene synthesis. Understanding MXene LCA will help with the industrial-scale manufacture of this 2D material . This article is protected by copyright. All rights reserved.

Colour descriptors for plant-based milk alternatives discrimination.

Colour characteristics of plant-based milk alternatives (PBMAs: almond, coconut, cashew, oat, soy) were monitored during long-term storage to select suitable descriptors for PBMAs differentiation. All colour descriptors evaluated varied depending on the raw material used in the plant-based milk alternative production. Long-term storage of plant-based beverages resulted in slightly noticeable (0.5-1.5) and noticeable (1.5-3.0) colour changes. Based on all colour descriptors, an absolute differentiation of PBMAs according to the type of raw material and storage time was achieved using canonical discriminant analysis. The results also indicate the possibility of using colour descriptors to detect the addition of honey to these products. Statistical analysis identified yellowness, browning index and lightness as the most discriminating parameters.

Milk productivity of first-calf heifers depending on the line and age of the first insemination

Relevance. One of the key types of raw materials that ensure the food security of Russian citizens is milk. To obtain it, dairy cattle are used, including Holstein, created by absorbing the breeding stock of domestic black-and-white cattle by bulls of the Holstein breed. The study of economically useful qualities of a new genetic formation of dairy cattle in the Middle Urals zone is of both scientific and practical interest.Methods. The aim of the work is to evaluate the milk productivity of Holstein cattle depending on the age of the first insemination, taking into account the linear origin.Results. As a result of the research, certain features were established that, in our opinion, are associated precisely with the origin (depending on the age of insemination, the animals are divided into 4 subgroups). So, in the group of heifers of the line Reflection Sovering 198998, the same trend of change in milk productivity depending on the age of the first insemination, as well as the average for the herd. The first heifers with the age of the first insemination up to 14 months had the highest productivity (p ≤ 0.05 between the 1st and 3rd groups in favor of the 1st). In heifers of the Vis Back Idial line, on the contrary, the highest milk yields were in animals inseminated for the first time at the age of more than 18 months. They have the highest milk yields compared to cows from other lines. The superiority ranged from 700 (Reflection Sovering line) to 2275 kg (Montwick Chieftain line) or 7.6–24.9% for the highest milk yields (р ≤ 0.05–0.01). Among the animals of the line Montvik Chieftain 95679 had the highest milk yield of first-calf heifers inseminated at the age of 14 months. They outperformed cows with other periods of insemination by 886–891 kg (р ≤ 0.05).

CHARACTERISTIC PHYSICOCHEMICAL OF BAMBOO-BASED ACTIVATED CARBON FOR COAL RUN-OFF WATER TREATMENT USED AT PT.BUKIT ASAM SLUDGE SETTLEMENT POND

The aim of this research were investigated bamboo-based activated charcoal (ABT)characteristics using Scanning Electron Microscopy (SEM) and Fourier Transform Infrared (FTIR). ABT has been successfully synthesized through physico-chemical activation at 700°C with H3PO4 10% solution as activator. The resulted were porous surface structure of bamboo charcoal causes an absorption interaction of pollutants (cations, anions, and suspended solids/TSS) in wastewater. Bamboo charcoal has different physical characteristics from charcoal from other types of raw materials because the structure with lignin composition is different from charcoal from other wood. The spectral patterns of AB and ABT are similar but differ in intensity. The functional groups detected in the two materials are the same, but there are differences in the absorption intensity where the ABT is relatively lower, especially in the hydroxyl functional groups at around 3400 and 1600 cm-1. This decrease in intensity is due to the dehydration process that occurs during both physical and chemical activation processes so that the hydroxyl groups come out of the bamboo charcoal structure

Manufacturing classification system for oral solid dosage forms of traditional Chinese medicines (Ⅱ): classification of tablets disintegration behavior

In this paper, 50 batches of representative traditional Chinese medicine tablets were selected and the disintegration time was examined with the method in Chinese Pharmacopoeia. The disintegration time and disintegration phenomenon were recorded, and the dissolution behaviors of water-soluble and ultraviolet-absorbent components during the disintegration process of tablets were characterized by self-control method. The results revealed that coating type and raw material type influenced the disintegration time of tablets. It was found that only 4% of traditional Chinese medicine tablets had obvious fragmentation during the disintegration process, while 96% of traditional Chinese medicine tablets showed gradual dissolution or dispersion. Furthermore, according to the disintegration speed, disintegration phenomenon, and whether the cumulative dissolution of measured components was > 90% at complete disintegration, a disintegration behavior classification system(DBCS) was created for the regular-release traditional Chinese medicine tablets. As a result, the disintegration behaviors of 50 batches of traditional Chinese medicine tablets were classified into four categories, i.e. ⅠA_2, ⅠB_1, ⅡB_1, and ⅡB_2. traditional Chinese medicine tablets(Class I) with disintegration time ≤ 30 min were defined to be rapid in disintegration, which can be the objective of optimization or improvement of Chinese herbal extract(semi extract) tablets. Different drug release models were used to fit the dissolution curve of traditional Chinese medicine tablets with gradual dissolution or dispersion phenomenon(i.e. Type B tablets). The results showed that the dissolution curves of water-soluble components in the disintegration process conformed to the zero order kinetics and the Ritger-Peppas model. It could be inferred that the disintegration mechanisms of type B tablets were a combination of dissolution controlled and swelling controlled mechanisms. This study contributes to understanding the disintegration behavior of traditional Chinese medicine tablets, and provides a reference for the design and improvement of disintegration performance of traditional Chinese medicine tablets.

Synthesis of Green Diesel from Palm Oil Using Nickel-based Catalyst: A Review

Petroleum is the primary energy that is generally used throughout the world. Its non-renewable nature and exhaust gas emissions that can damage the environment are a concern for developing environmentally friendly renewable energy. Green diesel is an alternative energy to replace diesel fuel (diesel) from petroleum which has the potential to be developed. The raw material in palm oil has great potential for development due to its relatively high production. Green diesel synthesis can be carried out using the catalytic deoxygenation method. The type of raw material, catalyst, and process conditions influences this method. The catalyst is the most influential factor in catalytic deoxygenation. Transition metal catalysts like nickel are inexpensive and have good catalytic activity like precious metals. Catalytic activity can be increased by modifying the catalyst components and optimizing the process. Modification of the catalyst can increase the surface area, Lewis and Bronsted sites, and crystal size so that the resulting green diesel can be maximized, such as Ni-Co, Ni-Zn, and Ni-Mo bimetallic catalysts.

Application of Scanning Electron Microscopy to Study Morphological and Anatomical Features of Sea Buckthorn Leaves

Introduction. Scanning electron microscopy is a modern method that allows us to study not only the morphological features of objects, but also to conduct micro-X-ray structural analysis. Currently, the method is being actively introduced into the study of biological objects (including plant ones). Sea buckthorn (Hippophaë rhamnoides L.) leaves are a non-pharmacopoeial type of medicinal plant raw materials. Further study of the morphology, anatomy and phytochemical composition of leaves can contribute to the production of new, including combined, medicines, which will require the development of a pharmacopoeia article for this medicinal plant raw material.Aim. The aim of the study was to study the morphological and anatomical features of sea buckthorn leaves by scanning electron microscopy.Materials and methods. The object of the study was dried whole leaves of sea buckthorn (Hippophaë rhamnoides L.), collected in the Voronezh region in 2021 during the period of mass fruit maturity. To carry out the study by scanning electron microscopy, pieces of leaves were previously sprayed with gold on an automatic spraying unit Q150R ES (Quorum Technologies Ltd., United Kingdom) to increase conductivity. Micrographs were obtained using an electron microscope JSM-6510LV (JEOL Ltd., Japan).Results and their discussion. The morphology and some features of the anatomical structure of sea buckthorn leaves were studied and the main microdiagnostic signs (surface character, types of trichomes, the presence of stomata) were clarified. The content of elements (silicon, potassium, aluminum, carbon and calcium) was determined during the microrentgenostructural analysis. Micrographs of pollen grains of the plant were obtained, the presence of the element iron in them was established.Conclusion. For the first time, the method of scanning electron microscopy was used to study the morphological and anatomical features of sea buckthorn leaves. The main diagnostic signs of leaves and their location have been clarified. It has been established that carbon predominates in the composition of the raw material elements, and calcium also accumulates. The accumulation of aluminum, silicon and potassium in numerous hairs densely covering the upper, and especially the lower, surfaces of the leaf blade is assumed. The morphology of the surface of pollen grains of sea buckthorn, having a spherical shape with a spiny shell, has been established. Pollen grains, in addition to carbon, are characterized by the accumulation of iron and silicon.
