The usage of various sourdoughs increases in order to expand the range and improve the quality, nutritional properties, and safety of bread products. Spontaneous sourdoughs with different formulas and preparation parameters are used in technologies of popular ethnic products. This paper is devoted to the study of wheat spontaneous sourdoughs, such as hop, pea-anise, and wine yeast sourdough. The effect of the grade and baking properties of flour, the inclusion of additional ingredients that can act as enrichers of the nutrient medium, carriers of additional fermentation microorganisms, as well as controllers of the species composition of the microflora, on their quality has been studied. The basic scheme of preparing spontaneous wheat sourdough is developed; the basic stages and parameters of the dilution and production cycles are noted. The methods of controlling the process and quality of sourdough are described, the recommended values of the lifting force and titrated acidity are presented, as well as sensory characteristics. It has been established, that the required fermentation ability and acid accumulation rate of sourdough are obtained in different time: 24 hours for wine yeast sourdough, 7–8 days for hop sourdough, and up to 15 days of a dilution cycle for pea-anise sourdough. The stabilizing effect of active substances of hop and anise on the quality of sourdough has been proven. Hop and pea-anise sourdough retain the necessary biotechnological properties for 90 days of propagation, but wine yeast sourdough loses its quality after 30 days, sourdough without additives loses it after 9 days. The results of the research have theoretical and practical use, since the proposed scheme and approaches to developing the wheat sourdough technology and controlling their quality can be used to study various ethnic sourdoughs and technology of bread based on them. The experimental data on the quality of selected sourdoughs can be used to develop the technology of bread products with improved quality, nutritional value, and safety, ethnic products, and products "made according to old technologies".

The article experimentally substantiates the prospects of obtaining powder from eggplant pulp, and its application in the technology of the national fried bakery product-baursaks. There are two ways to prepare eggplant for processing in order to remove bitterness. With preliminary freezing of raw materials, there is a slight bitterness in the aftertaste, and when soaked in a 3% salt solution, the taste of the powder is salty. The optimal parameters and modes of convective drying of eggplant fruits for the most complete preservation of biologically active substances in the product are established. The scientific novelty is confirmed by the patent of the Russian Federation № 2733117, a method for obtaining powder from the pulp of eggplant. The formulations of the experimental variants differed in the content of eggplant fruit powder by 15, 20, 25%. With an increase in the amount of eggplant pulp flour in the recipe to 20–25%, the color of the semi-finished product darkens, the dough becomes incoherent, breaks, because the content of raw gluten decreases in mixtures. According to the results of a comprehensive assessment of the quality of finished products, the best sample with the addition of eggplant pulp flour up to 15% in the product formulation. The authors found that in 100 g of baursaks with the addition of eggplant powder, the content of dietary fiber is 37,5% higher, vitamin B6 is 3 times, silicon, manganese, copper is 1,5 times. A new recipe of the national bakery product - baursaks has been developed, which contributes to the expansion of the range of products of increased nutritional value

In the course of research, experiments were conducted to study and describe the biological and economic features of Allium oschaninii O. Fedtsch. and Allium pskemense B. Fedtsch. in the Moscow region. The object of the research was samples of various ecological and geographical origin, obtained from various scientific institutions in Russia and other countries. The landing scheme was 70x30 cm. The area of the registered plot was 5 m2. Repeatability 4 times. Samples of Allium oschaninii O. Fedtsch. II years of life provided an average yield of green feathers at a level (2.85-3.86 kg/m2), and Allium pskemense B. Fedtsch. (2.593.20 kg/m2). Maximum yields were provided by samples No. 3 and No. 6 of Allium oschaninii O. Fedtsch. and samples No.3 and No.5 of Allium pskemense B. Fedtsch.. Correlation analysis showed that high productivity of the green feather is formed, first of all, due to the number of false stems (r = 0.909). Significant influence is exerted by such features as the number of leaves (r = 0.633), leaf length (r = 0.630), and the length of the false stem (r = 0.604). The nutritional value of Allium oschaninii O. Fedtsch. and Allium pskemense B. Fedtsch. is due to the presence of ascorbic acid (19.2-32.6 mg%), carotene (14.9-26.1 mg%) and biologically active substances, including flavonoids (251-325 mg% ), hydroxycinnamic acids, (155-194 mg%). The content of dry substances in the samples of the two onions studied was 10.3-12.7%, sugars 2.8-4.2%. The nitrate content did not exceed 170 mg%.

Background: Phytonutrients in peach fruits have health promoting antioxidants against various chronic diseases. However, there is no extensive data to show the nutritional values of Local peach cultivars after post-harvest treatments. Objective: Mainly this study was objective to determine the effect of calcium carbide on nutritional value and quality of fruits of Pakistani peach cultivars. Methods: The peach fruits were collected from three different peach orchids of KPK and the fruits were divided into 4 groups while 5th group was collected from local fruit shop. Each experimental group was treated with different concentration of calcium carbide whereas control group was not treated. The peel and pulp samples were oven dried and ground to fine powder separately. The elemental compositions were determined using Particle Induced X-ray emission and Pelletron Tandem Accelerator. Result: Sixteen elements were identified in peach fruits and the elements were Al, P, S, Cl, K, Ca, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, and Se. In peel, concentration of some elements increased or decreased after treatment with CaC2 while in pulp the conc. of nearly all detected elements was increased in treated samples. We found significantly high amount of heavy metals traces including As, Se, Co, Si, and P in peach fruits treated with CaC2. Interestingly, the presence of trichomes in peach skin prevents the transfer of these heavy metals deep into the pulp which was also verified by the elemental profiling of nectarines. Conclusion: Conclusively, the artificial ripening with CaC2 changed the nutritional value of peach fruits that has higher health risks if consume with the peel. According to our best knowledge, this is the first report that highlights the effects of CaC2 which deteriorate the nutritional value of peach fruits in Pakistan.

Type 2 diabetes has become one of the major health problems of the modern world. It is assumed that environmental factors have a significant impact on the development of the disease, and great importance is ascribed to the diet, which can be modified accordingly. The diet can exert prophylactic and therapeutic effects; changes in the diet in advanced disease can improve the quality of life of diabetic patients and minimise the risk of complications, which are the direct cause of diabetes-related death. Functional food, which has a potentially health-enhancing effect in addition to its nutritional value, has been increasingly recognised and required. Cereal products are crucial in diabetic nutrition. Their function can additionally be enhanced by fortification with compounds with proven hypoglycaemic effects. Pasta has a low glycaemic index and is a good carrier of fortifying substances; hence, it can be highly recommended in diets for diabetic patients.

The aim of the study was to present a comprehensive characterisation of crayfish meat, which is crucial to assess its potential usefulness in the food industry. To this end, we assessed the yield, basic chemical composition (protein, fat, minerals), nutritional value (amino acid and fatty acid profiles, essential amino acid index (EAAI), chemical score of essential amino acids (CS), hypocholesterolaemic/hypercholesterolaemic ratio (h/H), atherogenicity (AI) and thrombogenicity (TI) indices), as well as culinary value (lab colour, texture, sensory characteristics, structure) of the meat of spiny-cheek crayfish (Faxonius limosus) (n = 226) from Lake Sominko (Poland) harvested in May–September 2017. Crayfish meat, especially that from the abdomen, was shown to have high nutritional parameters. It is lean (0.26% of fat), with a favourable fatty acid profile and a very high quality of fat (PUFA (sum of polyunsaturated fatty acids):SFA (sum of saturated fatty acids), n-6/n-3, h/H, AI, TI) and protein (high CS and EAAI). It is also a better source of Ca, K, Mg, Na, P, and Cu than meat from slaughter animals. Hence, crayfish meat can be an alternative to livestock meat in the human diet. Owing to its culinary value (delicateness, weak game flavour, and odour), it meets the requirements of the most demanding consumers, i.e., children and older people.

AbstractIn addition to properly balancing nutritional value in accordance with the needs of a dog, estimating the microbiological quality of dog food is crucial in providing healthy and safe foods. The aim of this study was to examine the quality of dry food for adult dogs, with particular reference to: (1) evaluating the nutritional value and compliance with nutritional guidelines for dogs, (2) comparing the nutritional value of dog foods, with particular emphasis on the division into cereal and cereal-free foods, and (3) evaluating their microbiological safety. All thirty-six evaluated dry dog foods met the minimum European Pet Food Industry FEDIAF requirement for total protein and fat content. The total aerobic microbial count in the analyzed dry dog foods ranged from 2.7 × 102 to above 3.0 × 107 cfu/g. In five (14%) dog foods the presence of staphylococci was detected; however, coagulase positive Staphylococcus (CPS) was not found. Mold presence was reported in one cereal-free dog food and in six cereal foods. In none of the analyzed foods Enterobacteriaceae were found, including coliforms, Escherichia coli and Salmonella spp. Bacteria of the genus Listeria and Clostridium as well as yeasts were also not detected. In conclusion, the evaluated dry dog foods had varied microbiological quality. The detected number of microorganisms may have some implications for long-term consumption of contaminated food. The lack of European Commission standards regarding the permissible amounts of microorganisms in pet food may result in insufficient quality control of these products.

The influence of different drying methods on physical and nutritional properties of shrimp meat was investigated in this study. Peeled shrimps were dried separately using an air-oven dryer and a tunnel solar dryer. The drying profile of shrimp meat was determined in the two drying systems by monitoring moisture loss over the drying period. Changes in color, proximate composition, and rehydration capacity were assessed. The rate of moisture removal during solar drying was faster than the air-oven drying. The development of red color during drying was comparable among the two methods, but solar-dried shrimps appeared darker (L⁎=47.4) than the air-oven-dried (L⁎=49.0). Chemical analysis indicated that protein and fat made up nearly 20% and 2% (wb) of the shrimp meat, respectively. Protein and ash content of shrimp meat dried under the two dryer types were comparable but fat was significantly (p<0.05) higher in oven-dried meat (2.1%), compared to solar-dried meat (1.5%). Although rehydration behavior of shrimp from the two drying systems followed a similar pattern, solar-dried shrimp absorbed moisture more rapidly. The results have demonstrated that different approaches to drying may affect the physical and nutritional quality of shrimp meat differently.
