Prophylaxis method for incubating crap (C. carpio L.) eggs
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2020) Radu, Daniela; Costache, M.; Costache, Mioara; Marica, Nino
The paper presents the results obtained in the experiments carried out to control fungal infestations during the incubation of carp eggs. Experiments were carried out between 15 -24 May 2020 at the artificial fish breeding station at F.C.R.D.S. Nucet. Several concentrations of formalin (1 ml / l, 1.67 ml/l and 2 ml/l) and table salt (NaCl) (1 g / l, 3g /l, 5 g/l) were used to determine the duration and frequency of treatment for carp embryonated eggs. The effectiveness of formalin solutions was evaluated compared to that of table salt solutions by comparing the rate of hatching and larval survival. The results showed that formalin treatments, at a concentration of 1.67 ml / l for 15 minutes, inhibited fungal growth on the surface of embryonated eggs, resulting an incubation survival rate of 79.1% compared to untreated control samples.

Effect of seed spacelight storage on tomato fruit quality and peel/ pulp mineral and antioxidant distribution
(MDPI, 2024-03-18) Golubkina, Nadezhda; Dzhos, Elena; Bogachuk, Maria; Antoshkina, Marina; Verba, Olga; Zavarykina, Tatiana; Nechitailo, Galina; Murariu, Otilia-Cristina; Tallarita, Alessio Vincenzo; Caruso, Gianluca
The spaceflight storage of seeds is known to cause mutations affecting both their quality and the mature plants originating from them. To study the effects of space stress, tomato seeds of two cultivars (Lotus and Autumn rhapsody) were subjected to half a year of storage at the International Space Station (ISS), and then, sown in a greenhouse to produce tomato fruits. The space-treated plants gave smaller fruits with a stable total yield not significantly different from that of the control plants. Space-treated tomatoes showed significantly higher levels of dry matter, dietary fiber, monosaccharides and citric and malic acids and lower values of oxalic acid compared to the control plants. The pulp of space-treated fruits had 1.44–1.70 times lower levels of carotenoids, while their peel contained a 1.27–1.90 times higher pigment amount compared to the control plants. No significant changes in the total antioxidant activity (AOA), photosynthetic pigments and phenolic (TP) and proline content were recorded in the fruits due to seed spaceflight storage. Contrarily, space-treated tomatoes showed decreased levels of Ca, Sr and Mo and increased Se both in the fruit pulp and peel. The concentration of Fe and especially Pb was lower in space-treated fruit pulp. Positive correlations between Se and dry matter, Ca and Sr, Ca and Co, Ca and Fe, and Cr and carotenoids, and negative correlations between Se and Mo, Se and K, and Mo and dry matter were recorded. The results indicate that seed stress caused by long-term spaceflight affects both the biochemical characteristics and mineral composition of tomato fruits and causes the peel/pulp redistribution of carotenoids as well as macro- and micro-elements, improving Se accumulation levels in the fruit peel.

The Impact of Artificial and Natural Additives in Meat Products on Neurocognitive Food Perception: A Narrative Review
(MDPI, 2024-12-04) Ciobanu, Marius-Mihai; Flocea, Elena-Iuliana; Boișteanu, Paul-Corneliu
The holistic sensory experience creates a unified perception that influences consumer memory. Consumer interest in clean label products underlines an accelerated trend towards products without artificial additives. From a sensory point of view, food appeal is significantly influenced by how additives actively participate in the organoleptic properties of the final product. This research aims to shed light on the impact of artificial and natural additives in meat products on neurocognitive food perception, which is essential for understanding how they influence the consumer’s final decision and direct food trends. Different neural mechanisms involved in multimodal sensory integration confirm differences in perception of meat products containing artificial and natural additives. Analysis confirms that neurocognitive perception integrates organoleptic sensations to form a complete sensory experience. The encephalon simultaneously processes multimodally integrated stimuli from organoleptic properties, reaching the orbitofrontal cortex and other regions involved in the neuroprocessing of the final product. The reformulation and development of meat products need a detailed analysis of the impact of additives on sensory properties contributing to the shaping of consumption trends.

Maintenance status of rainbow trout (Oncorhynchus mykiss) reared in recirculating system and in earth ponds
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2020) M.D. Popa,; Tenciu, Magdalena; Patriche, N.; Mocanu, Elena; Savin, Viorica; Stroe, Desimira
The aim of this study is the comparative analysis of the anatomical components and the biochemical profile of one-year-old Oncorhynchus mykiss specimens, reared in recirculating system and in earth ponds. The analysis was performed by portioning the biological material in the main anatomical sections, followed by determining the biochemical parameters (moisture, ash, proteins and lipids), through standard methods of analysis corresponding to each parameter. Rainbow trout reared in a recirculating system has the meat percentage by 8.43%, the protein percentage by 19.93% and the fat percentage by 26.29% higher, compared to the rainbow trout reared in earth ponds. Rearing rainbow trout in a recirculating system is advantageous both due to the high production and the high quality of its biological value.

Stimulating disease resistance for common carp (Cyprinus carpio) reared in recirculating system, by utilising feeding diets supplemented with fatty acids
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2020) Mocanu, Elena; Patriche, N.; Tenciu, Magdalena; Savin, Viorica; Popa, M.D.
Fish production carries risks due to infectious diseases, unbalanced diet and environmental challenges which compromise fish welfare. Consumers demand a healthier and safer food and nutritionists recommend a diet low in saturated fat and rich in polyunsaturated fatty acids. The aim of this research is to investigate how diets supplemented with fatty acids affect the disease resistance of the carp species (Cyprinus carpio) 1 year of age, reared in a recirculating system. The experiment was performed in the recirculating pilot system, over a period of 2 months, using 120 specimens of carp (Cyprinus carpio) and three experimental feeding diets, supplemented with oils from various sources, rich in unsaturated fatty acids. In the experimental groups there were no mortality due to the use of oils rich in fatty acids that have the property to increase the immune system of the fish, compared to the control group where the survival was 86.66%. In the three experimental groups, at the end, a slightly higher level of proteins is observed in group T3 (18.18 g%), compared to group T2 (17.7 g%) and T1 (17.75 g%), the difference being proportional to the weight gain, but the difference is insignificant (p>0.05) which suggests the almost similar evolution of biological material in protein retention, regardless of the source of fatty acids. The feed conversion ratio and protein efficiency improved with the addition of lipids in the feeding diets. The addition of oils to feeding diets resulted in an increase in blood parameters measured in the experimental groups (PCV, Hb, Erythrocyte, MCV, MCH and MCHC), compared to parameters monitored at the beginning of the experiment and at the end of the experiment in the control group fed without oil supplements.
