The paper features nutritionally enhanced bakery products. N.I. Vavilov Saratov State Agricultural University conducts a series of research on the development of accelerated technologies for nutritionally enhanced bakery products. One of the main objectives of food industry is to develop healthy bakery products. Small power bakeries located in places of high demand are getting very popular. Mini-bakeries specialize in complementing products, e.g. malt rye bread and sweet rolls, as well as dietary, functional, and preventive bakery products. In Russia, apple juice is cheap and available, since apples are extremely widespread. Nevertheless, apple juice is rich in minerals, vitamins, enzymes, and organic acids. The authors developed an accelerated technology for bakery products fortified with apple juice. The technology can be used by small enterprises that would like to expand their product range with the help of domestic fortifiers. The experiment involved samples of cold technology bread, in which water was partially substituted with apple juice. The samples were tested on sensory, physical, and chemical properties. The article describes the effect of apple juice on the structural and mechanical characteristics of the samples, i.e. viscosity, shear velocity, crumb, shelf life, rheological properties, general and plastic deformation, etc. The research revealed that apple juice affects the discoloration of the bakery product, i.e. degree of whiteness, chromaticity, and other color characteristics. Consumer properties were tested by panelists. The experiment defined the nutrition value and chemical composition of the product and established the optimal dosage of apple juice in the formulation, which could maintain the best consumer properties and satisfy the daily requirement for nutrients. Thus, bakery products fortified with apple juice can contribute to the development of baking industry.

This article examines the issues of environmental pollution as a result of man-made activities and determines the most effective ways to protect the biosphere with the help of carbon-adsorption technologies. Due to their physical and chemical properties, activated carbons are an ideal adsorbent and allow solving a wide range of environmental safety issues. Based on the theoretical assumptions expressed by Academician M. M. Dubinin, it is shown that anthracite is an excellent raw material for producing activated coal. A technology for obtaining СAS (Crushed Anthracite Sorbent) grade activated carbons from anthracite has been developed and its adsorption properties have been studied. Tests of СAS activated carbon in the purification of drinking water and wastewater, protection of the atmosphere from harmful gases and vapors, and detoxification of soils from herbicide residues were carried out. The necessity and requirements for the creation of new production facilities for active coals based on anthracite in Russian coal basins are substantiated.

Abstract Bread is a useful biological product that remains high in the human diet and contains a large amount of substances necessary for the human. A rational way to expand the range of functional bakery products is to integrate natural plant-based ingredients into the formulation, which will increase the nutritional value of products, improve their sensory and physicochemical characteristics, create a group of new varieties, boost production, advance the quality of raw materials with low properties and save the critical and accessory raw materials. The paper discusses the effect of fruit enhancers on the physical and chemical properties of dough and finished bakery products. The paper proposes optimal dosages of fruit powders.

Delay in the consumption of bakery products has contributed to the food waste problem, which is a serious global issue. Delayed consumption or can be regarded as the ‘leftovers’ bakery products such as croissants and doughnuts are normally discarded due to the impairment in texture or quality degradation causing them to taste not as good as fresh baked, although the products still edible. Thus, this study aims to evaluate the physical and chemical changes during the delaying of consumption of croissants and doughnuts at three (3) different storage times (day 0, 1 and 2). The hardness of croissants and doughnuts had an increased throughout storage time, with doughnuts have the higher hardness than croissants, with 175.63 % and 92.31 % increased, respectively. Carbohydrate was found as the major component for croissants and doughnuts. Croissants and doughnuts recorded carbohydrate content of (50.32-52.42 %) and (43.22-46.59 %), respectively, from day 0 to day 2. While sugar profile analysis detected three types of monosaccharides sugars, which were fructose, glucose and maltose for croissants and doughnuts. Thus, high content of carbohydrate and monosaccharides that available in the leftovers doughnut and croissants suggest that it could potentially be used as renewable resources for sugar recovery.

Cashew apple juice (CAJ) is one of the feedstocks used for biofuel production and ethanol yield depends on the physical and chemical properties of the extracted juice. As far as can be ascertained, information on physical and chemical properties of South African cashew apple juice is limited in open literature. Therefore, this study provides information on the physical and chemical properties of the South African cashew apple juice. Physicochemical characteristics of the juice, such as specific gravity, pH, sugars, condensed tannins, Vitamin C, minerals, and total protein, were measured from a mixed variety of cashew apples. Analytical results showed the CAJ possesses specific gravity and pH of 1.050 and 4.52, respectively. The highest sugars were glucose (40.56 gL−1) and fructose (57.06 gL−1). Other chemical compositions of the juice were condensed tannin (55.34 mgL−1), Vitamin C (112 mg/100 mL), and total protein (1.78 gL−1). The minerals content was as follows: zinc (1.39 ppm), copper (2.18 ppm), magnesium (4.32 ppm), iron (1.32 ppm), sodium (5.44 ppm), and manganese (1.24 ppm). With these findings, South African CAJ is a suitable biomass feedstock for ethanol production.

The present work presents a packaging system that slows down the degrading and ageing processes of bakery products as well as mould appearance. There have been selected three packing methods: the packing in PE folio, PP folio, PP punched folio and the packing in a small bag specially designed to preserve bakery products. The selection has been done function of physical – mechanic and chemical properties of the packaging materials and according to the requirements of a good preservation of the packed product. The PE folio has a good mechanical resistance, a good permeability to gases and a high impermeability to water vapors. The PP folio has a greater contraction, a better transparency and better mechanical properties than the polyethylene. The permeability to water and gas vapors is lower than that of the polyethylene. The complex material based on textile / PE has superior physical and chemical properties and a high impermeability to moisture, gas and flavors. The experimental bread packaging methods prove a tight link among the permeability to water vapors, the duration of the product freshness and the mould appearance. The specially designed small bag made of two cotton lays and one polyethylene lay preserves the freshness of sliced bread, because the bread does not get dry or wet. After a 7-day storage period, the contamination degree with Penicillium frequetans of the sample packed in PP punched folio is of 5%. The contamination degree with Penicillium nigricans and frequetans of the sample packed in PP folio is of 85%. The sample packed in the cotton bag is 10% contaminated with Aspergillus fumigates, and the one packed in polyethylene folio is 20% contaminated with Aspergillus versicolor and Penicillium frequetans.

Continuing studies on the physical and chemical properties of foot-and-mouth disease virus (FMDV) have included electron microscopy of RNA strands released when highly purified virus (1) was dialyzed against demlneralized distilled water. The RNA strands were dried on formvar-carbon coated electron microscope screens pretreated with 0.1% bovine plasma albumin in distilled water. At this low salt concentration the RNA strands were extended and were stained with 1% phosphotungstic acid. Random dispersions of strands were recorded on electron micrographs, enlarged to 30,000 or 40,000 X and the lengths measured with a map-measuring wheel. Figure 1 is a typical micrograph and Fig. 2 shows the distributions of strand lengths for the three major types of FMDV (A119 of 6/9/72; C3-Rezende of 1/5/73; and O1-Brugge of 8/24/73.

Biomimetics involves investigation of structure, function, and methods of synthesis of biological composite materials. The goal is to apply this information to the design and synthesis of materials for engineering applications.Properties of engineering materials are structure sensitive through the whole spectrum of dimensions from nanometer to macro scale. The goal in designing and processing of technological materials, therefore, is to control microstructural evolution at each of these dimensions so as to achieve predictable physical and chemical properties. Control at each successive level of dimension, however, is a major challenge as is the retention of integrity between successive levels. Engineering materials are rarely fabricated to achieve more than a few of the desired properties and the synthesis techniques usually involve high temperature or low pressure conditions that are energy inefficient and environmentally damaging.In contrast to human-made materials, organisms synthesize composites whose intricate structures are more controlled at each scale and hierarchical order.
