Carotenoids have well documented health-promoting functions through their antioxidant properties, and numerous research topics are related to their integration in functional food products or beverages. Due to their firm hydrophobic nature, some difficulties are encountered while incorporating them in high water content matrices. In the present study recovered carotenoids from tomato processing industrial by-products were qualitatively and quantitatively analyzed by high-performance liquid chromatography (HPLC), and microencapsulated via spray drying technology. Oil in water (o/w) emulsion delivery system was used for encapsulating carotenoids with linseed oil as carrier, and a binary blend of gum Arabic and maltodextrin (1:1 w/w) as wall materials. The microcapsules were subjected to physical-chemical analysis, and to simulated gastrointestinal digestion process to evaluate the carotenoids bioaccessibility. Individual carotenoids (lycopene, β-carotene, and lutein) were observed during gastric and intestinal phases of the in vitro digestion and analyzed by HPLC/DAD. The results showed considerable degradation of lycopene during spray drying process and consistent degradation of β-carotene throughout the gastric phase of the simulated digestion. To gain an insight into the compounds responsible for the efficient delivery system of the carotenoids through the gastrointestinal tract, further investigations are required regarding the lipid phase used in the spray drying process.

The circular economy action plan involves principles related to food waste reduction and integration of recovered nutrients to the market. In this context, the present study aims to highlight the valuable bioactive components found in tomato processing by-products (carotenoids, phenolic compounds and fatty acids) influenced by industrial pre-treatments, particularly cold break (CB) process at 65–75 °C and hot break (HB) process at 85–95 °C. The fatty acid profile of the tomato seed oil was examined by gas chromatography coupled to mass spectrometry (GC-MS), individual carotenoid and phenolic compositions were determined by high performance liquid chromatography (HPLC) and the viscoelastic properties were evaluated by rheological measurements. The physicochemical properties revealed appropriate characteristics of the tomato seed oil to fit the standards of generally accepted edible oils, for both CB and HB derived samples, however, significant qualitative and quantitative differences were detected in their phenolic composition and carotenoids content. Lycopene (37.43 ± 1.01 mg/100 mL) was a major carotenoid in the examined samples, linoleic acid was the main fatty acid (61.73%) detected in the tomato seed oil and syringic acid appeared to be one of two major phenolic acids detected in the samples of CB process. Our findings extend the boundaries of tomato processing industry by validating that tomato seed oil is a bioactive rich edible oil with additional health benefits, which can be integrated in functional food products.

Nowadays, technological advancement is in continuous development in all areas, including food packaging, which tries to find a balance between consumer preferences, environmental safety, and issues related to food quality and control. The present paper concretely details the concepts of smart, active, and intelligent packaging and identifies commercially available examples used in the food packaging market place. Along with this purpose, several bioactive compounds are identified and described, which are compounds that can be recovered from the by-products of the food industry and can be integrated into smart food packaging supporting the “zero waste” activities. The biopolymers obtained from crustacean processing or compounds with good antioxidant or antimicrobial properties such as carotenoids extracted from agro-industrial processing are underexploited and inexpensive resources for this purpose. Along with the main agro-industrial by-products, more concrete examples of resources are presented, such as grape marc, banana peels, or mango seeds. The commercial and technological potential of smart packaging in the food industry is undeniable and most importantly, this paper highlights the possibility of integrating the by-products derived compounds to intelligent packaging elements (sensors, indicators, radio frequency identification).

An efficient micropropagation protocol for Rheum rhabarbarum L. was developed in this study. The in vitro rhubarb plants obtained in the multiplication stage (proliferation rate: 5.0 ± 0.5) were rooted in vitro (96% rooting percentage) and acclimatized ex vitro in floating perlite, with 90% acclimatization percentage. To assess the genetic fidelity between the mother plant and in vitro propagated plants, sequence-related amplified polymorphism (SRAP) markers were used. All banding profiles from the micropropagated plants were monomorphic and similar to those of the mother plant indicating 100% similarity. Regarding the polyphenolic profile, gallic, protocatechuic, p-hydroxybenzoic, vanillic, chlorogenic, caffeic, syringic, p-coumaric and ferulic acid were present in different amounts (2.3–2690.3 μg g−1 dry plant), according to the extracted matrix. Aglicons and glycosides of different classes of flavonoids were also identified. The rhizome extracts (both from in vitro and field grown plants) contained resveratrol, a stilbene compound with high antioxidant properties, ranging between 229.4 to 371.7 μg g−1 plant. Our results suggest that in vitro propagation of Rheum rhabarbarum L. represents a reliable alternative to obtain a large number of true-to-type planting material with high bioactive compound content of this valuable nutritional and medicinal species.

In the current work the physicochemical features of poly(vinyl alcohol) (PVOH) biofilms, enriched with eco-friendly polyols and with carotenoid-rich extracts, were investigated. The polyols, such as glycerol (Gly), 1,3-propanediol (PDO), and 2,3-butanediol (BDO) were used as plasticizers and the tomato-based pigments (TP) as coloring agents. The outcomes showed that β-carotene was the major carotenoid in the TP (1.605 mg β-carotene/100 DW), which imprinted the orange color to the biofilms. The flow behavior indicated that with the increase of shear rate the viscosity of biofilm solutions also increased until 50 s−1, reaching values at 37 °C of approximately 9 ± 0.5 mPa·s for PVOH, and for PVOH+TP, 14 ± 0.5 mPa·s in combination with Gly, PDO, and BDO. The weight, thickness, and density of samples increased with the addition of polyols and TP. Biofilms with TP had lower transparency values compared with control biofilms (without vegetal pigments). The presence of BDO, especially, but also of PDO and glycerol in biofilms created strong bonds within the PVOH matrix by increasing their mechanical resistance. The novelty of the present approach relies on the replacement of synthetic colorants with natural pigments derived from agro-industrial by-products, and the use of a combination of biodegradable polymers and polyols, as an integrated solution for packaging application in the bioplastic industry.

Active films were prepared from poly(vinyl alcohol) (PVA) blended with itaconic acid (Ia), and with chitosan (Ch), enriched with tomato processing by-products extract (TBE) in order to develop new bioactive formulations for food packaging. The effects of two biopolymers (Ch, Ia) and of the incorporated TBE—containing phenolic compounds and carotenoids—were studied regarding the physical and antimicrobial properties of films; in addition, their influence on the total phenolic content, viscosity, and flow behavior on the film-forming solutions was investigated. The results showed increased physical properties (diameter, thickness, density, weight) of the films containing the TBE versus their control. TBE and Ch conferred significant antimicrobial effects to PVA films toward all the tested microorganisms, whereas the best inhibition was registered against S. aureus and P. aeruginosa, with a minimum inhibitory concentration of

The genetic relationship among three Streptocarpus parents and twelve F1 hybrids was assessed using sequence-related amplified polymorphism (SRAP) molecular markers and Fourier-transform infrared (FT-IR) spectroscopy. Both methods were able to discriminate F1 hybrids and parents as revealed by cluster analysis. For hybrid identification, the type III SRAP marker was the most effective due to the presence of male-specific bands in the hybrids. Different behaviors in the biochemical variability of DNA samples have been observed by FT-IR spectral analysis, which might be attributed to the inherent nature of the genomic DNA from parents and their F1 progenies. Mantel test was also carried out to compare morphological, SRAP, and FT-IR results based on genetic distances. The highest correlation coefficient was found between morphological and SRAP marker distances (R = 0.607; p ≤ 0.022). A lower correlation was observed between the morphological and FT-IR distance matrix (R = 0.231; p ≤0.008). Moreover, a positive correlation was found between the distances generated with SRAP and FT-IR analyses (R = 0.026) but was not statistically significant. These findings show that both SRAP and FT-IR techniques combined with morphological descriptions can be used effectively for nonconventional breeding programs for Streptocarpus to obtain new and valuable varieties.

Fruits and vegetables are essential for human nutrition, delivering a substantial proportion of vitamins, minerals, and fibers in our daily diet. Unfortunately, half the fruits and vegetables produced worldwide end up as wastes, generating environmental issues caused mainly by microbial degradation. Most wastes are generated by industrial processing, the so-called by-products. These by-products still contain many bioactive compounds post-processing, such as macronutrients (proteins and carbohydrates) and phytochemicals (polyphenols and carotenoids). Recently, the recovery of these bioactive compounds from industry by-products has received significant attention, mainly due to their possible health benefits for humans. This chapter focuses on the bioactive potential of fruit and vegetable by-products with possible applications in the food industry (functional foods) and in the health sector (nutraceuticals).

Tomato processing industry generates high quantities of by-products rich in bioactive compounds such as polyphenols. The present study evaluated the carotenoids, phenolics and amino acids content of ten tomato varieties processing wastes, and the correlation with their antimicrobial and antioxidant properties. Antimicrobial activity was tested against seven microorganisms and the antioxidant capacity of the extracts was assessed with the 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay. In addition, the fatty acid composition of the tomato seeds was evaluated by GC-MS. Overall, the mean content of total carotenoids, phenolic compounds and amino acids was 30.2 ± 10.8, 242 ± 89 and 3310 ± 1217 mg/100 g dry weight, respectively. Total lipids represented 21% from the tomato seeds, with linoleic acid being the major compound (88% of total lipids). The extracts had good antibacterial activity against Gram-positive bacteria (e.g. Staphylococcus aureus), which correlated well with the amount of isochlorogenic acid in each tomato variety. The antioxidant activity was high for all genotypes, and especially for the Tiny Tim variety which contains significantly higher amounts of flavonol glycosides and isochlorogenic acid than the other varieties. Our results support the need of a better revalorization of tomato processing wastes.

Global tomato production is currently around 180 million tons, of which more than a quarter undergoes processing. The removed peels, seeds, and vascular tissues usually end up in landfills, creating environmental pollution. In order to highlight the alternative use of these vegetal wastes, our study investigated 10 tomato varieties in terms of carotenoids content, phenolic composition, and their related antioxidant and antimicrobial activities. Tomato peels extracts were screened by high performance liquid chromatography with diode-array detection (HPLC/DAD) for qualitative and quantitative analyses. The extracts were tested against six bacterial strains to determine their antimicrobial effect; the 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay was applied to estimate their antioxidant capacity. Total carotenoids content was significantly higher in Ţărănești roz, a local variety (5.31 ± 0.12 mg/100 g DW), while Mirsini, a commercial hybrid, presented significantly higher total phenolic content (155 ± 2 mg/100 g DW) compared to the mean value of all analyzed samples. The methanolic extracts of tomato peels presented acceptable antimicrobial activity against Staphilococcus aureus and Bacillus subtilis, and the mean antioxidant activity was 201 ± 44 µmol Trolox/100 g DW tomato peels. Considering that tomato peels have lycopene, β-carotene, lutein, and different phenolic compounds in their composition, tomato industrial by-products could represent a source of natural bioactive molecules with applicability in nutraceuticals and food industry.

Some species of the Ericaceae family have been intensively studied because of the beneficial health impact, known since ancient times, of their chemical components. Since most studies focus on the effects of fruit consumption, this review aims to highlight the phenolic components present in the leaves. For this purpose, five species from Ericaceae family (bilberry—Vaccinium myrtillus L., lingonberry—V. vitis-idaea L., bog bilberry—V. uliginosum L., blueberry—V. corymbosum L. and bearberry—Arctostapylos uva-ursi L.) were considered, four of which can be found in spontaneous flora. The chemical composition of the leaves revealed three major phenolic compounds: chlorogenic acid, quercetin and arbutin. The health promoting functions of these compounds, such as antioxidant and anti-inflammatory properties that could have preventive effects for cardiovascular disease, neurodegenerative disorders, cancer, and obesity, have been exemplified by both in vitro and in vivo studies in this review. Furthermore, the importance of bioaccessibility and bioavailability of the phenolic compounds have been summarized. The findings highlight the fact that leaves of some Ericaceae species deserve increased attention and should be studied more profoundly for their biological activities, especially those from spontaneous flora.

Alongside paper, plastic, metal and glass, an important segment in the recycling area is represented by the wastes of different vegetal processing industries. These by-products gained interest lately, in the context of food waste prevention and growing population number. In the tomato processing industry approximately, 8.5 million tons of wastes are generated globally, each year. The present study highlights the valuable bioactive constituents as lycopene, beta-carotene, glutamic acid or aspartic acid from the by-products of tomato processing industries, which can be revalorized as incorporated nutrients in functional foods. Tomato consumption is directly associated with the prevention of different chronic diseases and carcinogenesis, however the carotenoids bioavailability is a key factor in this process. Further, fiber content together with protein content of tomato seeds and benefits of their consumption are emphasized. Value–added food products obtained by tomato peels or seeds addition are exemplified in this review (bakery, meat products, pasta and noodles, dairy and oil products as well as jams and functional ice cream), in order to embrace next prototypes that can transform vegetal by-products in functional nutrients.

In Romania, Prunus genetic resources are held in collections located mainly in research and development institutes or in fruit growing stations. A possible disadvantage of the utilization of these resources for genetic studies and also for breeding programmes is the lack of reliable data for correct identification and characterization of accessions. In this study, 27 plum accessions from Râmnicu-Vâlcea Fruit Research Station, Romania, were assessed using nine SSR markers generating a total of 134 distinct alleles, with an average of 14.89 alleles per locus. Differentiation between the Romanian plum cultivars and international reference cultivars was low, but significant, for all the nine loci (Fst = 0.012; P < 0.0001). Plum accessions were grouped in two clades, both including old and newly developed Romanian cultivars and also international reference cultivars, according to an UPGMA dendrogram. Bayesian analysis of genetic structure revealed significant admixture among examined accessions while principal coordinate analysis performed on the molecular data illustrated a substantial dispersion of old and newly developed Romanian plum accessions in the three-dimensional PCoA scatter plot. These results could make them attractive for future breeding programs and long-term conservation strategies based on identified genetic dissimilarities.

In Romania, Prunus genetic resources are kept in collections of varieties, populations and biotypes, mainly located in research and development institutes or fruit growing stations and, in the last years, by some private enterprises. Creating the experimental model for the Germplum database based on phenotypic descriptors and SSR molecular markers analysis is an important and topical objective for the efficient characterization of genetic resources and also for establishing a public-private partnership for the effective management of plum germplasm resources in Romania. The technical development of the Germplum database was completed and data will be added continuously after characterizing each new accession.

Astragalus exscapus (Fabaceae) is a melliferous, perennial plant, which fits within a rarity type characterized by having small populations of relatively high habitat specificity (Rabinowitz, 1981). Astragalus exscapus L. ssp. transsilvanicus (Schur) Nyár. is an endemic subspecies, which has been identified in the Transylvanian basin in 24 populations. In order to establish conservation strategies and to characterize polymorphism of the threatened subspecies, genetic and morphologic analysis has to be implemented. Our study describes the application and optimalization of SRAP procedures to A. exscapus, including sampling, DNA extraction, PCR amplification and electrophoresis. Sequence Related Amplified Polymorphism (SRAP) molecular marker system is going to be used on eight different populations of A. exscapus ssp. transsilvanicus to identify the degree of polymorphism which is essential for the evolution of species. The methodology was tested and optimized successfully in two repetitive experiments. The results confirmed the suitability of the DNA extraction method to be applied and the optimization of the SRAP technique for the large-scale studies we are performing on this subspecies.
