The aims of the present work are to estimate the nutritional value and to evaluate and compare the levels of macroelements (Ca, P, K, Na, Mg), microelements (Fe, Zn, Mn, Cu), heavy metals (Co, Cd, Pb, Mo, Cr, Ni), and their ratios in extruded complete foods for adult dogs, their compatibility with nutritional guidelines, as well as food profile similarity. Basic composition was determined according to Association of Official Analytical Chemists (AOAC). Analyses for elements were performed using an atomic absorption spectrometer. All the evaluated dry dog foods met the minimum recommended levels for protein and fat. Eighteen tested dog foods (60%) did not meet at least one recommendation of nutritional guidelines. Four dog foods exceeded the legal limit of Fe and five foods exceeded the legal limit of Zn; in one of them, Zn level was almost twice higher. Dog foods with insect protein exceeded the legal limit for Mn content. Eight dog foods had an inappropriate Ca:P ratio. Heavy metals were below detection limit in all analyzed dog foods. The results seem to show the need for regular feed analyses of the elemental composition in raw materials before introducing supplementation and for the monitoring of the mineral composition of finished pet food.

Zephyr is one of the most favorite sweets in Russia: tender and airy. So, in 2017, the share of zephyr accounted for 23.5% in the segment of sugary confectionery products in Russia, which in physical terms amounted to 251.5 thousand tons. Its popularity among consumers is facilitated by the fact that natural fruit raw materials are used in the manufacture of zephyr. The modern industrial technology of zephyr is developed on the basis of folk recipes for pastila, which was made from apples and honey as a way of preserving apples. Zephyr is a pastila type confectionery of a foamy structure, the mass fraction of fruit raw materials in which is not less than 11%, the density is not more than 0.6 g / cm3. The use of a large amount of fruit raw materials in zephyr increases the nutritional value and enriches it with macro- and micronutrients. Pectin gives additional beneficial properties to zephyr, since it is able to bind heavy metals and radionuclides. The mass fraction of pectin in zephyr is in the range from 3% to 9%, which turns zephyr into a source of dietary fiber. To preserve the unique Russian dessert, the Research Institute of the Confectionery Industry has developed a method for determining the mass fraction of fruit raw materials in pastila products based on the ratio of the mass fraction of organic acids and macronutrients, the values of which are determined using the method of capillary electrophoresis. 34 samples of zephyr presented in the retail chains of the Russian Federation were studied for compliance with the requirements of the state standard for the content of fruit raw materials. High content of fruit raw materials from 11 to 60% was confirmed for most samples.

The aim of this study was to estimate complete extruded dry food for adult dogs, with a particular focus on the nutritional value with respect to current nutritional guidelines for dogs, dietary fiber fractions, the division into breed size. Dog foods were subjected to chemical analyzes to determine the content of basic nutrients and dietary fiber fractions. The material for the research consisted of 15 maintenance foods for adult dogs (five for large breed dogs, five for small breed dogs and five for all breeds dogs). All analyzed feeds met the European Pet Food Industry Federation recommended minimum recommended levels of protein and fat. Individual tested foods were characterized by different levels of dietary fiber fractions, such as acid detergent fiber (ADF), cellulose (CEL), hemicellulose (HCEL). The group of foods for small breed dogs was characterized by the lowest mean of ME (391.23 kcal per 100 g DM). A higher level of ME (393.99 kcal per 100 g DM) was observed in the group of foods for dogs of large breeds, and the highest (397.05 kcal per 100 g DM) – in the group of foods for dogs of all breeds.

Health indicators of the population depend significantly on the food quality and nutritional value. Simple carbohydrates excess of and lack of protein, dietary fiber, vitamins, minerals, antioxidants and other physiologically active substances increase the risk of socially significant disease progress. The development and production of mass-consumed products with high nutritional and biological value, including affordable non-traditional raw materials use, are promising areas of the food industry development aimed at improving the nutritional status of the population. The article presents the research results on the developed Noodle products recipes from non-traditional raw materials that meet modern healthy nutrition requirements, intended for dietary treatment and dietary prevention of people with overweight / obesity. The research aimed at expanding the range of macaroni products with these characteristics. As the main raw material, a man selected whole-wheat flour – new spelt flour, and as additional raw materials – buckwheat flour, broccoli and celery powders. The researchers found that the introduction of macaroni products from buckwheat spelt, broccoli and celery powders into the recipe had a multidirectional effect, reducing or increasing various indicators of its nutritional value. The changes range did not affect the overall characteristics. The satisfaction degree of the average daily need for food substances and energy when consuming a portion of 100 g for each sample of developed Noodle products allows them to be classified as functional products that are protein and dietary fiber sources, according to the requirements of the TR CU 022/2011.

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.

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 presented study was aimed at the determination of the level of contamination with heavy metals (Cd, Pb, As, and Hg) in 240 samples of plant materials, i.e., herbal raw materials, spices, tea, and coffee. Moreover, a probabilistic risk assessment (noncarcinogenic and carcinogenic risks) was estimated by models including target hazard quotient (THQ) and cancer risk (CR). The samples were subjected to microwave mineralisation with the use of HNO3 (65%), while the determination of the content of the elements was performed with the use of inductively coupled plasma mass spectrometer (ICP–MS) and a mercury analyser. The element which was characterised by the highest level of accumulation in the analysed samples was lead (from 0.010 to 5.680 mg/kg). Among the heavy metals under analysis, the lowest concentration was noted in the case of mercury (from 0.005 to 0.030 mg/kg). A notably higher level of contamination with heavy metals was noted in the analysed samples of herbs and spices (0.005–5.680 mg/kg), compared to samples of tea and coffee (0.005–0.791 mg/kg). According to the guidelines of the World Health Organisation (WHO) concerning the limits of contamination of samples of herbal raw materials with heavy metals, lead levels exceeding the limits were only noted in 24 samples of herbs (18%). In all of the analysed samples of spices, tea, and coffee, no instances of exceeded limits were noted for any of the analysed heavy metals. The values of TTHQmax (in relation to the consumption of the analysed products) were as follows: up to 4.23 × 10−2 for spices, up to 2.51 × 10−1 for herbs, up to 4.03 × 10−2 for China tea, and up to 1.25 × 10−1 for roasted coffee beans. As the value of THQ ≤1, there is no probability of the appearance of undesirable effects related to the consumption of the analysed group of raw materials and products of plant origin. The CR value for As (max. value) was 1.29 × 10−5, which is lower than the maximum acceptable level of 1 × 10−4 suggested by United States Environmental Protection Agency (USEPA).

AbstractDried fruits are an excellent alternative to unhealthy snacks. Twelve commercially available dried fruits were selected: dates, raisins, prunes, Goji berry, chokeberry, rose hip, sea buckthorn, berberis, physalis, haritaki, noni and juniper. The nutritional value in terms of moisture, ash, protein, fat, carbohydrate, dietary fiber, energy value, mineral composition, antioxidant activity and tannins was compared. It is a novelty in the literature in relation to the particular analytes (e.g., minerals, tannins) and/or fruits (e.g., berberis, noni, haritaki). Especially rich in protein were Goji berry (13.3%), sea buckthorn (9.3%), noni (8.9%) and physalis (8.0%); in fat − sea buckthorn (11.2%); in dietary fiber (4.4–53.0%) − most of analyzed products. High antioxidant capacity was noticed for haritaki, berberis, rose hip, Goji berry, and physalis. An important source of minerals was 100 g of: noni (345 mg of Ca; 251 mg of Mg), rose hip (844 mg of Ca; 207 mg of Mg), juniper (564 mg of Ca), sea buckthorn (58 mg of Fe), berberis (24 mg of Fe) and haritaki (14 mg of Fe). The nutritionally attractive dried fruits have the potential for wider application in food formulations.
