As of recent times, consumers are starting to be more and more aware of the impact nutrition has over their health. The present study is based on the use of antioxidants and their consumption through meat products. In this sense, the study focused on using a survey to evaluate the consumers’ understanding of what antioxidants are and their potential health benefits, their perceptions of the taste and quality of meat products that contain antioxidants, as well as their willingness to purchase such products. The survey showed that most consumers are aware of the potential harmful effect of long-time consumption of synthetic antioxidants. The surveyed people also stated that they consume meat and meat products almost on a daily basis; however most stated that they would not repurchase a meat product if the used natural antioxidant would cause changes in the product’s colour and taste. As shown in the study, research methods such as surveys can provide valuable insights into consumers' attitudes and purchasing habits.

Acidic dairy products are produced using a specific formula that relies on a multitude of variables. The process of optimizing this formula involves systematically adjusting one or more of these variables to achieve the desired outcome. Diary acid products formulation undergo rigorous testing to identify one that resonates with consumers and meets their acceptance criteria. In the quest to create a novel product with specific predefined attributes, an experimental design is employed based on the outcomes of sensory analyses conducted on representative products slated for optimization. The mathematical modelling of consumer acceptance responses provides a valuable tool for researchers to pinpoint the ingredients and/or processes that yield the greatest product acceptability while minimizing costs. This approach ultimately aids in the formulation of precise manufacturing specifications tailored to meet consumer expectations. In this study, seven traditional acidic dairy products available in the market were carefully evaluated to determine the most desirable attributes. Subsequently, two unique product formulations were developed, which exhibited exceptional sensory characteristics based on the findings. To assess the significance of these results, a statistical analysis was conducted using SPSS® version 16. The outcomes of this analysis, following the sensory evaluation, confirmed that the optimized products successfully met the specific qualities originally intended in the design.

Even if the Romanian market has been overrun in recent years by non-indigenous hybrids, the high degree of adaptability of the Romanian varieties helps them to persist in the struggle for survival. The demands of organic consumption have determined a segment of the country's population to refocus on the consumption of indigenous apples or originating from other areas, but grown for a very long time in our country. The interest for these varieties with tasty fruits and special flavors led us to make a microbiological and molecular assessment. Molecular variability was investigated using ISSR (Inter Single Sequence Repeats) and SCoT (Start Codon Targeted) markers. The microbiological methodology is based on techniques for the isolation and determination of mesophilic bacteria, molds, yeasts, the presence of faecal bacteria and Escherichia coli, Salmonella and Shigella species. Escherichia coli was observed in some samples and enterococci were highlighted in only one sample. The results indicate a variation of the microbial groups in the varieties analyzed and the absence of species that can disturb serious the digestive tract (for example Salmonella and Shigella).

The current study investigates the effect of the probiotic Saccharomyces cerevisiae BB06 on the growth performance of carp (Cyprinus carpio). The experiments were conducted in a laboratory-scale re-circulating system over an eight-week trial period. Ninety healthy carp were randomly divided into three groups and fed with fish feed containing 0% yeast biomass (control), 3% yeast biomass (YBV3%), and 5% yeast biomass (YBV5%). The fish were fed twice daily with a quantity of feed corresponding to 2.5% of their body weight. Growth performance increased significantly (p<0.05) with increasing levels of probiotic S. cerevisiae BB06. The YBV5% group performed the best in terms of the final body weight, weight gain rate of Cyprinus carpio. The mortality rate of the fish fed with the probiotic S. cerevisiae BB06 was 0%. An increase in the yeast content of the feed had a tendency to decrease in the value of the Fulton condition factor. In addition, fish fed diets enriched with S. cerevisiae BB06 showed improvements in feed conversion ratio and protein efficiency ratio. Water quality parameters were maintained at acceptable levels in all tanks during the eight-week trial period, allowing high growth rates and production of the carp. In conclusion, dietary supplementation with S. cerevisiae BB06 can improve the growth performance of carp (Cyprinus carpio).

The paper presents the evolution of fish production from commercial fishing in the Danube River during 2015-2021 and is based on the analysis of statistical data collected by the National Agency for Fisheries and Aquaculture as part of the data collection program. Production data were collected annually by authorized commercial fishermen, quantitatively and by species. During the analysed period, there is a quantitative decrease in the production of wild carp and raptors, and significant increases in catches of Asian carp species. Catches of Danube record annual fluctuations with decreasing trends in the analysed period. At the end, the causes of the catches decrease of commercial fishing are analysed and the fisheries management measures that must be taken, based on ecosystem principles, to protect and restore the declining fish populations in the Danube River.

Dietary fibers are components of plant material, extremely important in the diet, because they resist enzymatic digestion in the digestive tract, with a role in improving intestinal transit. Dietary fibers are mostly carbohydrates such as cellulose, hemicellulose, pectic substances, gums, and mucilages, but also non-carbohydrate. The presence in the daily diet of whole grains, nuts, vegetables, fruits and seeds positively affects health, because their consumption has been linked to the decrease in the incidence of several diseases. From a technological point of view, dietary fiber is added as a functional food ingredient in food products to provide water-holding capacity, viscosity, gel-forming capacity and fat-binding capacity to food products. These beneficial characteristics of dietary fiber components can enhance the image of products as healthy and functional foods. This article reviews the concept and definition of dietary fibers used in food production and their functional characteristics and health benefits.

Immunoglobuline synthesis is largely determined by the presence of the type of antigen that enters the body. However, various biological bioactive substances have a potential to boost individual immunity processes. In this study, 5 weeks old BALB/c was used. This study aims to evaluate the role of the combination of Curcuma xanthorrhiza and Curcuma longa lyophilisate on serum immunoglobuline-G level, angiogenesis process and BALB/c body weight. The bio-active substances were distrubuted through drink water. This study used a randomized complete design arranged with factorial 2*4. The results showed that treatment had no significant effect on IgG levels and the process of angiogenesis (P>0.05), but had a significant effect on body weight (P<0.05). We concluded that combination of Curcuma xanthorrhiza and Curcuma longa lyophilisate could be used in wound healing during an angiogenesis process.

The saffron crocus (Crocus sativus) is a flowering plant of the Iridaceae family A spice called saffron is obtained from the dried red stigmas of the flower and is used in the pharmaceutical, cosmetic, perfumery and textile industries. It has been grown in our country for a short time, but the areas with this culture are rapidly increasing. To date, no scientific research has been conducted on this type of plant in our country. In the present article, we summarize scientific observations on the influence of climatic factors, temperature, and air humidity on the honey qualities of the saffron crocus. We determined the amount of nectar and its sugar content, the amount of individual pollen from one flower, and the size and shape of the pollen grains in the pollen. We tracked the flowering period and the number of flowers against the age of the planted bulbs.

Successful animal husbandry is impossible without the organization of a balanced feeding system, and in particular is providing rations with optimal level of mineral elements and vitamins, which serve as a guarantee of the intensity of metabolic processes in the body as well as assimilation of feed nutrients and their conversion into products. Multi-ingredient feed supplements are the best source of replenishing the rations of dairy cows with nutrients. The morphological and biochemical composition of blood is a symptomatic reflection of the metabolism intensivity. Feeding cattle an improved vitamin and mineral supplement (VMS), as part of the improved compound feed K 60-32-89, makes it possible to ensure a sufficient level of vitamin and mineral nutrition in the Pre-Carpathia zone. The balanced ration of dairy cows with biologically active substances (BAS) enhances the redox reactions of the body (probably a higher level of erythrocytes, hemoglobin, total protein, nitrogen fractions) while simultaneously accumulating energy in the cell (increasing total acid-soluble phosphorus and nucleic acids (NA)) and the growth of the level of milk productivity by 9.8%.

A twenty-five weeks study of Black Barbus, P. nigrofasciatus fry was conducted to determine the effectiveness of various combinations of feed and its effect on growth, survival, and physiological and hematological parameters composition of fish blood. To achieve this goal, Black Barbus, P. nigrofasciatus fry were kept in three identical 120-liter aquariums, and fed different diets. The first diet included industrial feed in the form of flakes. The second diet included live microorganisms and crustaceans. The third diet was a 1:1 combination of industrial feed and live organisms. The results of the study showed a higher growth rate in Black Barbus, P. nigrofasciatus, which consumed combined feed, than peers consumed dry feed by 0.60 cm or 10.53% (p<0.05) and then peers consumed live feed by 0.20 cm or 3.28% (p<0.05). The content of hemoglobin in the blood was the same in fish of three diets. The level of erythrocytes was higher by 0.12 million×μl-1 in the blood of fry, whose diet was combined.
