Quantitative characterisation of chicken breast optimised with different amounts of brine
No full textChicken meat is considered an affordable source of high-quality protein and a complete provider of essential nutrients required for proper bodily functions. It has gained popularity not only in developed countries but especially in nations with growing economies. While the meat processing industry emphasizes the technological aspects of meat, consumers are keen on its sensory and nutritional attributes. This study aimed to characterize and compare three batches of chicken breast pastrami injected with three different brine percentages (5%, 8%, and 12%) in terms of physicochemical attributes (pH, colour, moisture, protein, lipid, and salt content) as well as sensory characteristics. The study results revealed significant differences between the pastrami batches concerning moisture and protein content (p<0.05). The brine percentage had a notable impact on the colour and pH properties of the meat products. In terms of cross-sectional colour, the data analysis indicated that meat samples injected with the higher LBI3 brine percentage exhibited increased lightness (73.13) and a more pronounced yellow hue (9.40) compared to the other two samples injected with 5% brine (70.97, and 8.90, respectively) and 8% brine (71.25, and 8.73, respectively). In terms of sensory evaluation, the samples were assessed for attributes such as colour, texture, juiciness, flavour, and overall acceptability. The batch of chicken breast pastrami injected with 8% brine (LBI2) received favourable scores for overall quality and colour, whereas the LBI3 batch distinguished itself with texture and juiciness, which were highly appreciated by the evaluators
The Biochemistry and Effectiveness of Antioxidants in Food, Fruits, and Marine Algae
No full textIt is more effective to maintain good health than to regain it after losing it. This work focuses on the biochemical defense mechanisms against free radicals and their role in building and maintaining antioxidant shields, aiming to show how to balance, as much as possible, the situations in which we are exposed to free radicals. To achieve this aim, foods, fruits, and marine algae with a high antioxidant content should constitute the basis of nutritional elements, since natural products are known to have significantly greater assimilation efficiency. This review also gives the perspective in which the use of antioxidants can extend the life of food products, by protecting them from damage caused by oxidation as well as their use as food additives
The impact of modern agricultural technologies on cereal production efficiency in Romania
No full textGiven the ever-increasing need for food and the challenges of climate change, as well as the availability of European
funding for agriculture, it is crucial to adopt advanced agricultural technologies to maintain and improve agricultural
efficiency. This study aims to assess the impact of modern agricultural technologies on the efficiency of cereal
production in Romania. Using data collected from N.I.S., we examined the relationship between the implementation of
technologies such as irrigation systems, farm equipment and chemical fertilizers and grain yield, assessed as the
relationship between total production and area of land cultivated, using multiple linear regression. Findings indicate that
agricultural technology and infrastructure significantly influence the level of production. The increase in the number of
tractors, ploughs and combines indicates a trend towards modernisation and mechanisation in the Romanian agricultural
sector. This is in line with farmers' efforts to respond to the growing demand for cereal products and to benefit from the
opportunities offered by the NRDP
The study of the behavior of some corn hybrids for the optimization of the cultivars structure under irrigation conditions in Iasi county
No full textCommercial corn hybrids have a very high yield potential, with valuable features of adaptation to more or less favorable growing conditions. In the particular conditions of technology applied in a certain farm and in particular climatic conditions of the crop year, the production and the efficiency can approach more or less the yield potential of these hybrids, through their comparative testing being able to obtain information to determine the best assortment. Evaluation of the results obtained following the testing of three semi-early corn hybrids, from three different companies, at SC Semtop Group in Iași county, at sowing plots of 80,000 and 70,000 germinable grains/m2, respectively, and under conditions of optimal assurance of the necessary irrigation water allowed to highlight the hybrids that behave best in the respective conditions
Drying Process Modeling and Quality Assessments Regarding an Innovative Seed Dryer
No full textThe dehydration of agricultural products is a topic of research covering the preservation and conservation of the quality of agricultural and food items. The actual tasks of environmental protection include creating novel solutions to reduce the energy needs and exothermic consequences of the bulk of industrial processes. Due to the fact that air temperature and velocity in the seed layer are not uniform, the currently employed seed dryers have significant energy requirements and generate a lot of heat. A device that addresses this problem was developed and is now the subject of a patent application. The Coandă effect-based tronconic plates used in the dryer enable warm air to be dispersed uniformly throughout the product mass. Mathematical modeling was used for the design, operation, and optimization of the baffled drying unit. The investigations, which were conducted by modifying and observing the operational parameters (the velocity and temperature of the warm air) used four distinct types of seed with three different beginning moisture concentrations. Following the completion of the CFD simulation, the unit’s design was created in SolidWorks. The seed and air humidity were measured using sensors, and the air speed was measured using an anemometer. The current lines and fields were used to express the speed and temperature results. The unit with deflectors reduced the amount of heat released by up to 15.38% and reduced the amount of energy used by up to 14%
The enigma of poverty and steps in its solution
No full textMany of us are aware of the existence of poverty and its impact on a country, but we often overlook the fact that the
best way to combat such a negative phenomenon is to identify and address the root causes that generate it or at least
to improve them. The authors aim, through this work, to conceptualize the economic phenomenon of poverty and
define it in the context of the current economy. Through an extensive literature review, this article seeks to define the
types of poverty, particularly in rural areas, and identify their defining characteristics in the current economy. Rural
areas undergo transformation over time due to economic, social, and environmental factors, which is why addressing
poverty in rural settings should be integrated and coordinated to tackle these causes and create opportunities for
sustainable development in these areas. This economic phenomenon has always been a complex and persistent issue
that requires significant efforts to address and ensure equal opportunities for development and prosperity for rural
residents. The conceptualization of this phenomenon cannot be reduced to a single cause; it is the result of a
combination of interrelated factors. As a result of interpreting the specialized works, we will identify the various
perspectives through which this economic phenomenon is defined and the indicators used to measure it
Study regarding estimation of heritability for milk production traits in Holstein cattle
Get PDFThe goal of this study is to estimate the heritability of milk, fat, and protein yields in Holstein cows from a dairy farm in Iași, Romania. The heritability of these traits during the first lactation is examined using 16 bulls and their 542 progeny and was estimated the heritability of milk, fat, and protein yields during the first lactation. Data was statistically processed with ANOVA. The findings reveal a lower heritability for milk yield (0.15 ± 0.06), a moderate heritability for fat yield (0.30 ± 0.12), and a strong heritability for protein yield (0.64 ± 0.23). These results showed that protein yield exhibits the most significant genetic influence, while milk yield demonstrates the least. The findings regarding milk yield and fat percentage should be interpreted with caution due to their proximity to the limits of the specialized data range. However, it is important to note that the observed heritability for protein percentage may be of particular difference, potentially influenced by human error or the transmission of data in an improper manner
Research on the influence of the preceding crop on the yields of the triticale crop under the conditions of A.R.D.S. Secuieni
No full textOne of the important factors contributing to increased yield is represented by crop rotation, which by alternation can reduce or prevent infestation with weeds, pathogens, plant and soil pests, but can improve the texture and structure of the soil so that the next crop can capitalize these benefits. Considering that the grain yield of straw cereals is influenced by the number of ears per surface unit, the number of grains per ear but also by the individual weight of the grain, this study was carried to determine which preceding crop favorably influences the yiled of grains to the triticale crop. The experience was placed in the experimental field at A.R.D.S. Secuieni, and followed the influence of three preceding plants: soybeans, sunflower and corn on grain yield at two triticale varieties: Haiduc and Utrifun. Following research, the best average yields were obtained when the triticale was cultivated after corn and soybeans. Of the two varieties of triticale, Utrifun stood out for its superior yields, with average values between 6213 kg﮳ ha-1 and 8277 kg﮳ ha-1

Get PDFRecent studies have highlighted that the risks for developing cardiovascular alterations are significantly increased in
patients who previously suffered from Covid-19. This study aims at determining the functional and structural long-term
effects of Covid-19 disease on the cardiovascular system using a specific and original humanized mouse model
recapitulating the endogenous cardiovascular expression of the SARS-CoV-2 main receptor ACE2 (Angiotensin
Converting Enzyme 2). We will focus on studying the systemic and pulmonary vessels and the cardiac tissue to
understand how SARS-CoV-2 infection leads to cardiac and vascular tissue remodelling and function alteration
Diagnostic and therapeutic protocol for mammary tumours in canines and felines
Get PDFMammary tumors are a common pathology among female cats and dogs, and less common in males of these species.
Intact and older females are more susceptible to this condition. A mammary tumor is typically suspected when a lump is
discovered during a physical examination of the abdominal area, along the mammary chains. Although surgical
treatment is the therapy of choice in most cases, sometimes chemotherapy may be also required. Establishing a correct
diagnosis is the foundation for individual optimisation of treatment, as well as the possibility to predict the course of the
pathology and prognosis. Diagnosis is based on obtaining an accurate history, clinical, paraclinical and imaging
examination of the patient. All this will allow a tumor staging, which will guide therapy and prognosis. This article
presents a diagnostic and therapeutic algorithm developed after centralizing the latest data published in the literature,
providing a guide in the management of mammary tumors in canids and felines
