Exploitation of red beet peel powder as a natural food ingredient in whey-fruit based beverage
(Taylor & Francis, 2024-11-13) Stoica, Florina; Rațu, Roxana-Nicoleta; Lipșa, Florin-Daniel; Motrescu, Iuliana; Cara, Irina-Gabriela; Râpeanu, Gabriela; Aprodu, Iuliana; Țopa, Denis-Constantin; Jităreanu, Gerard
Scientists and food producers are studying the potential of utilizing different by-products as highly nutritious food components to meet consumers’ growing demand for healthier and natural goods. Beetroot belongs to the Amaranthaceae family and is highly rich in antioxidants, specifically phenolics and betalains with excellent health properties. The peel of red beetroot, which is generally discarded, has a high concentration of bioactive phytochemicals (betalains, dietary fibers). These compounds are well-known for their strong antioxidant effects, improving cardiovascular health, reducing oxidative stress, and enhancing immunological function. Incorporating red beetroot peel (RBP) powder into whey-fruit-based beverages is a promising method to improve nutritional content and sensory attractiveness. This study investigated the influence of adding RBP to whey-fruit-based beverages, specifically examining its effects on physicochemical and phytochemical characteristics, antioxidant capacity, color, microbiological, and rheological attributes, and consumer preference. The RBP extract exhibited high amounts of total polyphenols (1239.35 ± 0.51 mg GAE/100 g dw) and antioxidant activity (90.02 ± 0.22%). The findings indicated that RBP had a notable impact on the antioxidant capacity (16.38 ± 0.37 μmol TE/g dw for BRBP1, 26.69 ± 0.10 μmol TE/g dw for BRBP3, 36.75 ± 0.31 μmol TE/g dw for BRBP6) of the beverages and enhanced their color without negatively impacting their sensory characteristics. The dynamic oscillatory rheological measurements revealed that beverage supplementation with increasing amounts of RBP obtained stronger networks with solid-like viscoelastic behavior. Using RBP powder as a natural food ingredient in whey-fruit-based beverages enhances their nutritional value and promotes sustainable food processing by making use of by-products from the food industry into innovative food options.

Influence of Soil Texture on Carbon Stocks in Deciduous and Coniferous Forest Biomass in the Forest-Steppe Zone of Oka–Don Plain
(MDPI, 2024-11-17) Sheshnitsan, Sergey; Odnoralov, Gennadiy; Tikhonova, Elena; Gorbunova, Nadezhda; Sheshnitsan, Tatiana; Murariu, Otilia-Cristina; Caruso, Gianluca
Forests play a crucial role in climate change mitigation by acting as a carbon sink. Understanding the influence of soil properties on carbon stocks in forests is essential for developing effective forest management strategies. The aim of the study was to assess the impact of soil texture on carbon stocks in the biomass of deciduous and coniferous tree stands of a forest-steppe ecotone. Soil samples were collected from 55 soil pits, and forest inventory data were obtained from eight permanent sample plots. The results showed that the distribution of mechanical particles in soils, particularly the stocks of silt and clay, significantly influenced the accumulation of carbon in tree stands. The stock of silt and clay was shown to increase with an increase in the diversity of tree species in forests and carbon stocks in forest stands. While soil organic carbon stocks did not exhibit a clear relationship with tree stand carbon stocks, a strong positive correlation (r = 0.802, p < 0.05) was found between the stocks of fine particles in the 2 m root-inhabited soil layer and the carbon stocks in tree biomass. The study provides a classification of forest types based on soil texture, which can facilitate differentiated forest management strategies for enhancing the carbon sequestration potential of forest ecosystems in the forest-steppe zone.

Stainless Steel Deposits on an Aluminum Support Used in the Construction of Packaging and Food Transport Containers
(MDPI, 2024-11-11) Radu, Steluța; Toma, Ștefan Lucian
A series of chemical elements from the chemical composition of the packs of liquid food products migrate inside them or they combine with other chemical elements existing in the food, resulting in chemical compounds that worsen the quality of the food. In the present paper, layers of food stainless steel were deposited using thermal arc spraying on an aluminum alloy substrate to stop the migration of aluminum ions inside liquid food products. The physical-chemical and mechanical properties of the protection system: stainless steel layer used in the food industry (suggestively called: food-grade stainless steel)—aluminum substrate were investigated, and then the organoleptic properties of the food liquids that came into contact with the deposit were evaluated. It was found that food-gradestainless steel deposits have low porosity (3.8%) and relatively high adhesion and hardness, which allows complete isolation of the substrate material. The investigations carried out on the properties of food liquids that come into contact with the stainless steel deposit revealed the fact that it perfectly seals the aluminum start. The food-grade stainless steel coating (80T) was much better and safer for preserving dairy products maintaining a constant acidity up to 17 degrees Thorner, wines (with an average acidity of 3.5–4 degrees), juices (with natural pigments), and oils (with a good absorbance level correlated with clarity). This aspect suggests that the created system can be successfully used to manufacture containers for the transport of liquid products.

Evaluation of the Wear Properties and Corrosion Resistance of 52100 Steel Coated with Ni/CrC by Cold Spraying
(MDPI, 2024-01-21) Lupu, Fabian-Cezar; Munteanu, Corneliu; Müftü, Sinan; Benchea, Marcelin; Cimpoeșu, Ramona; Ferguson, Gehn; Boese, Sam; Schwartz, Patricia; Istrate, Bogdan; Arsenoaia, Vlad-Nicolae
Coatings deposited by the cold particle gas spray method have shown significant potential for enhancing the properties of metals. We investigated the wear characteristics and corrosion behavior of 52100 steel coated with a mixture of Ni/chromium carbide (Ni/CrC) particles. These coatings exhibited high density and were devoid of cracks, closely adhering to the substrate’s surface. Microscratch resistance testing revealed strong resilience, with the apparent friction coefficient exhibiting multiple peaks as the displacement varied. The determination of the friction coefficient, utilizing linear and rotational sliding tests, displayed a brief transition period. This occurred as the apparent contact area expanded until it reached an equilibrium state, with the large asperities being smoothed out and the remaining particles on the sliding track acting as an abrasive material, resulting in higher friction coefficient values. Electro-corrosion tests confirmed the near-intact condition of the deposited layer. Few compounds were detected in the electrolyte solution, resulting in significantly lower oxidation in the layer compared to the base material.

Aspects on the constructive and internal organization solutions for the transformation of a pig growing house in beef cattle growing house
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Leonte, C.; Leonte, Doina
The present work highlights some aspects regarding the possibilities of transforming some shelters from pig farms, built before 1990, into spaces for the exploitation of beef cattle. Cattle capitalize on agricultural by-products and waste (straws, cheeses, chickens, chickpeas, beets and beet noodles, pork in the processing industry, bran, mackerel) which they transform into essential foods for human food. Cattle provide the raw material needed for the milk and meat industry. Meat and delivered products are important sources of energy, proteins, minerals, vitamins, essential amino acids, necessary for the proper functioning of human physiological mechanisms and for maintaining health. The hall for raising pigs has a structure of reinforced concrete, the foundations are glass type, with pillars embedded in these foundations, supporting at the top end beams of the roof. In the first compartmentalization version (V1), 16 cows / storage can be accommodated ensuring a total area of 162 m² and 10.12 m² / cow. In total, the 9 compartments can accommodate 144 cows. For the calves there are 25 compartments with a total area of 337.5 m² and 2.25 m² / calf. There are also two compartments for calving on the ends of the shelter with 13.5 m² / compartment. This variant provides an external feed lane for cows with a width of 3.5 m and an inner feed lane for calves with a width of 3 m. In the second compartmentalization version, 108 cows can be accommodated, ensuring a total area of 1150.2 m² and 10.65 m² / cow. The calves can be accommodated in the 18 storage boxes resulting from the compartmentation with a total area of 575.1 m², resulting in 5.32 m² / calf. The forage in this variant can be made from a central alley with a width of 3.8 m.
