The recovery of bioactive compounds from agro-industry-derived by-products sustains circular economy principles by encouraging maximized recycling and minimized waste. Tomato processing by-products are abundant in carotenoids, which have several health-promoting properties, and their reintegration into functional food products represents a major interest for scientists and manufacturers. In the present study, carotenoids were recovered from tomato processing by-products based on the principles of green chemistry by using generally recognized as safe (GRAS) solvents, freeze-drying as pretreatment, and ultrasound in the recovery procedure. Spectrophotometric measurements and HPLC were used to identify and quantify total and individual carotenoids from the extracts. The highest values for lycopene (1324.89 µg/g dw) were obtained when ethyl lactate was applied as a solvent, followed by ethyl acetate with slightly smaller differences (1313.54 µg/g dw). The extracts obtained from freeze-dried samples presented significantly lower amounts of lycopene, indicating that carotenoids are highly susceptible to degradation during lyophilization. Flaxseed, grape seed, and hempseed oils were enriched with carotenoids and their rheological measurements showed favorable viscoelastic properties, especially hempseed and flaxseed oil, with viscosity under 50 mPa·s. Considering the results and the economic perspective of carotenoid recovery from tomato processing by-products, ethyl acetate is suitable, sustainable, and environmentally friendly for carotenoid extraction.

Increased interest in tomato (Solanum lycopersicum L.) production requires breeding to create new cultivars with highly marketable values (e.g., regarding quality, nutrition, and health) and valuable sensorial parameters. The purpose of this research was to compare four tomato commercial hybrids—two newly created and two used as controls in the breeding process, cultivated in a high plastic tunnel, regarding a wide range of physico-chemical properties as well as nutritional and organoleptic components of the fruits, which are relevant for the quality of the tomatoes. The new AS 400 commercial hybrid registered the best results for carotenoids (16.64 mg 100 g−1 FW) and dry matter (6.88%). The highest total ascorbic acid value (28.03 mg 100 g−1 FW) was recorded in the other new hybrid, AS 300, while the highest values of total acidity were recorded on the Precos, used as the control (184.87 mg NaOH 100 g−1 FW). The correlations between the analyzed characteristics and the multivariate analysis provided insight into breeding tomatoes to meet the current fruit quality requirements. Based on the results, hypotheses have been formulated for the creation of new cultivars with anticipatory, prospective character, in order to ensure the future needs of the market and consumers.

Arbuscular mycorrhizal fungi (AMF) are beneficial for plant development and help absorb water and minerals from the soil. The symbiosis between these fungi and plant roots is extremely important and could limit crop dependence on fertilizers. The aim of this study was to evaluate the influence of AMF on tomatoes (Solanum lycopersicum L.), based on important agronomic traits of vegetative biomass, production, and fruits. The experiment was conducted in high tunnels, using 12 tomato genotypes under three different treatments: T1, control, without fertilizer and mycorrhizae colonization; T2, fertigation, without mycorrhizae colonization; and T3, arbuscular mycorrhizal fungi (AMF), seedling roots being inoculated with specialized soil-borne fungi. Plant growth, yield and fruit parameters indicated better results under mycorrhizal treatment. Root colonization with fungi varied significantly depending on the treatment and genotype, with a variation of 6.0–80.3% for frequency and 2.6–24.6% for intensity. For a majority of characteristics, the mycorrhization (T3) induced significant differences compared with the T1 and T2 treatments. In addition, AMF treatment induced a different response among the genotypes. Among the elements analyzed in the soil, significant differences were observed in phosphorous levels between planting the seedlings and after tomato harvesting and clearing of the plants. The results suggest that reducing fertilizers and promoting the symbiotic relationships of plants with soil microorganisms may have beneficial consequences for tomato crops.

Raspberry is a delicious fruit with important nutritional and health properties for consumers. The efficiency of achieving raspberry breeding aims such as productivity, fruit quality, and adequate response to stressors, etc., depends directly on knowledge of the inheritance of traits and genetic factors of influence and their pragmatic use. In this study, the main morphological characteristics and chemical components of fruits of 24 raspberry genotypes were studied in a comparative field trial; 14 were promising selections and the other 10 included their parental forms (Autumn Bliss, Glen Moy, Glen Prosen, Opal, Pathfinder, Titan, Tulameen, Veten, Willamette) and Glen Ample cultivar, which was used as control. The results highlighted significant differences and a large variation among the genotypes (between 2.40 and 4.90 g for fruit weight, 0.19–0.47 kg/cane for yield, 50–106 for drupelets/fruit, 10.0–12.7% for dry matter, 0.23–2.00% pectin, 1.61–2.72% glucose, etc.). The inheritance of the analyzed traits, considered quantitative, was different, but a low heritability was recorded for non-marketable fruits and the number of drupelets in fruit. In several hybrid selections, negative heterosis prevailed, highlighting the breeding difficulties of the important desired traits of the species. The values of heterosis and the broad-sense and narrow-sense heritability of some traits demonstrate that, through judiciously choosing parents, raspberry breeding in the desired direction can be successful.

An analysis of the research, innovation and technology transfer environment carried out by the European Commission ranks Romania in one of the last places in Europe, mentioning the lack of investments in research, especially at the level of modern infrastructure and equipment, among the most important reasons. On the other hand, Romanian universities must face the competition at the international and the European level, in order to face the technical and socio-economic challenges both at the societal level, and with respect to the inherent technological evolutions. Under these conditions, this article presents a case study of a top university in Romania that has, for the first time in its history as an EU member, successfully implemented European structural funding investment and research grant for building a new advanced research institute at the level of excellence compatible with the most demanding expectations in the field of horticulture, and is using it in accordance with the standards of the European Research Area. In an analysis of the results of all horticultural labs covered by the new institute, also from a perspective of cross-cutting collaboration between them, during a 5-year study of sustainability, the model presented demonstrates the effectiveness and efficiency of European structural funds in the field of scientific research. It is a real success of advanced research, innovation, development, and technology transfer, which can be adopted by any other university in the EU.

Consumers have become more interested in leading better and higher quality lives, and have become more aware of the health effects nutrition has on their body, stimulating the development of functional foods (FF), recognized for their ability to provide physiological benefits that go beyond conventional nutritional function. The evolution of this product category is supported by the progress of research on bioactive compounds and changing consumer preferences, but empirical evidence regarding the level of knowledge, acceptance and purchasing behavior of Romanian consumers remains insufficient. Meanwhile, technology in the food industry has evolved significantly in recent decades, creating opportunities for entrepreneurs and consumers. Using empirical evidence from a survey carried out on the consumers in the region of Transylvania, the study uses a cross-sectional observational design and investigates the awareness of and the population’s differences in perception and attitude on FF products depending on the generations and socio-economic situations consumers belong to, and the impact FF have on the market. The analysis focuses on food choice behaviors, degree of trust in health benefits and factors influencing the decision-making process. The results show that consumers are not aware of the FF concept, but understand the relation between food choice behaviors and personal health and act accordingly. Results also show that older consumers are more aware of their health, and younger consumers are more influenced by trends. This paper can be of importance to consumers, entrepreneurs, food and technological industries, governments and universities.
