... The decline in raspberry production in Romania in recent decades was caused by various factors, among which the most important are the lack of investment in modern technologies, labor migration, and limited access to funds. Despite this, Romania remains renowned for the superior quality of its fruit, particularly for its intense flavor, aroma, and therapeutic benefits [2,3]. Thanks to its favorable climate Investments in raspberry cultivation and production are not only essential ways to improve nutrition, food security, and economic efficiency but are also vital in promoting and participating in a sustainable economic model. ...
This paper presents a study on the establishment and the capitalization of a remontant red raspberry crop, the Polka variety, on a privately agricultural land area of 0.2 ha in a crop with a support system in V using a geotextile membrane for soil mulching and the method of micro-irrigation by drip. It has been shown that the annual gross profit is advantageous for diversifying the population incomes of rural areas, and the red raspberry is economically profitable regarding cultivation because the recovery of the invested sum is achieved in a maximum of 5 years after the establishment of the culture. The aim of this paper is to explore the growth and commercialization of red raspberry cultivation on privately owned arable land in rural Romania, emphasizing its potential for productivity and sustainability in the context of the circular economy. This initiative not only delivers substantial profits for investors but also fosters rural development and boosts local income levels. The study demonstrates that this cultivation method of red raspberry, aligned with the principles of the circular economy, enhances sustainability by reducing waste, optimizing resource use, and involving local communities in production cycles.
... This difference points to the need for further research into the relationship between tannin levels in fruit and corresponding fruit wines, taking into consideration the tannin levels of chokeberry (from 522 to 1000 mg/100 g FW 320/fresh weight/), blackberry (160 mg/100 g FW) and raspberry (120 mg/100 g FW) reported in other studies [49,50]. Proanthocyanidins are the major class of tannins in blueberries and chokeberries, with chokeberries characterized by the highest content of condensed tannins among 100 plant foods investigated [51]. ...
The modern analytical technique of Fourier-transform mid-infrared spectroscopy (FT-MIR) has found its place in routine wine quality control. It allows rapid and nondestructive analysis, with easy sample preparation and without the need for chemical pretreatment or expensive reagents. The objective of this research was to apply these advantages to fruit wines in order to create a tool for the authentication of fruit wines produced from different fruit species (chokeberry, blackberry, and raspberry). The aim of this work was to establish a chemometric model from FT-MIR spectra and to find a “fingerprint” of specific fruit wines, enabling the classification of fruit wines by plant species. Physicochemical analysis of 111 Croatian fruit wine samples (38 liqueur fruit wines and 73 fruit wines) revealed content levels of the following parameters: alcoholic strength (5.0–15.2% vol.), total dry extract (60.4–253.3 g/L), total sugars (1.2–229.9 g/L), pH (3.13–4.98), total acidity (4.2–18.3 g/L) and volatile acidity (0.2–1.5 g/L). For statistical data processing, spectral ranges between 926 and 1450 cm−1 and between 1801 and 2951 cm−1 were used. The first principal component (PC1) explained 70.4% of the observed variation, and the second component (PC2) explained 16.7%, clearly separating chokeberry fruit wines from blackberry and raspberry fruit wines. Soft Independent Modeling Class Analogy (SIMCA) was performed following the development of a PCA model showing that the chokeberry and blackberry wine samples form clearly separated clusters. Key discriminators for classifying chokeberry vs. blackberry wines were identified at 1157, 1304, and 1435 cm−1, demonstrating high discrimination power (DP 26, 17, and 14, respectively). FT-MIR spectroscopy, in combination with chemometric methods, has shown promising potential for the authenticity assessment of fruit wines.
... Additionally, berry fruits contain phytochemicals like phenolic acids (hydroxybenzoic and hydroxycinnamic acid), flavonols (quercetin, kaempferol, myricetin), flavanols (catechins and epigallocatechin [EC]), anthocyanins (cyanidin glycosides and pelargonidin glucosides) and flavonoids like tangilanins. Anthocyanins responsible for the color of the fruit are found in abundant amounts in the skin of the fruit [15][16][17][18][19][20]. Due to these rich bioactive components, there is increasing demand for berry fruits in recent years. ...
Global climate change and possible drought scenarios have forced researchers, breeders and producers to create new plant patterns that will adapt to changing climate and soil conditions for production of horticultural plants in the future. Here, the most important topic is the shortening of the physiological growth period of plants due to abiotic stress. In other words, reductions experienced in both cooling needs and matu-ration periods cause negative impacts on flowering times and amounts, and this causes significant loss of yield. In recent years, the production of berry fruits that will adapt to drought conditions has attracted the attention of breeders and producers. The aim of this study is to discuss in detail the possibilities of producing berry fruits that are resistant to drought and negative climate conditions and to present research results and recommendations about this topic. In this study, the production opportunities in arid and negative climate conditions for the berry fruits of strawberry (Fragaria vesca L.), mulberry (Morus spp.), fig (Ficus carica L.), blackberry (Rubus fruticosus L.), choke-berry (Aronia melanocarpa L.), rosehip (Rosa canina L.), raspberry (Rubus idaeus L.) and blueberry (Vaccinium myrtillus L.) were researched and recommendations are made about production methods for some varieties and types resistant to drought in berry fruit cultivation.
... High-quality food with a functional, curative, and beneficial effect on human metabolism is increasingly desired worldwide. In this context, polyphenols which are present in a variety of food, e.g., in fruits and vegetables, tea, coffee, chocolate, whole grains, red wine, food by-products, and wastes [1][2][3][4], have received increasing attention for their positive impact on human health due to their bioactive properties, mainly antioxidant and anti-inflammatory ones [5][6][7][8][9][10]. Plenty of investigations have reported a positive effect from the consumption of polyphenol-rich food on incidences of chronic illnesses such as cardiovascular disease [11], diabetes mellitus [12], and cancer [13]. ...
Polyphenols are plant-based compounds famous for their positive impact on both human health and the quality of food products. The benefits of polyphenols are related to reducing cardiovascular diseases, cholesterol management, cancers, and neurological disorders in humans and increasing the shelf life, management of oxidation, and anti-microbial activity in food products. The bioavailability and bio-accessibility of polyphenols are of the highest importance to secure their impact on human and food health. This paper summarizes the current state-of-the-art approaches on how polyphenols can be made more accessible in food products to contribute to human health. For example, by using food processing methods including various technologies, such as chemical and biotechnological treatments. Food matrix design and simulation procedures, in combination with encapsulation of fractionated polyphenols utilizing enzymatic and fermentation methodology, may be the future technologies to tailor specific food products with the ability to ensure polyphenol release and availability in the most suitable parts of the human body (bowl, intestine, etc.). The development of such new procedures for utilizing polyphenols, combining novel methodologies with traditional food processing technologies, has the potential to contribute enormous benefits to the food industry and health sector, not only reducing food waste and food-borne illnesses but also to sustain human health.

... Plasma aspartate aminotransferase (AST) levels in LBP diets were higher compared to other diets and as an indicator of liver damage, we speculate that an inflammatory process in the liver might contribute to the increased weight. Dietary factors contribute to changes in metabolism in the liver, and the higher tannins concentration in LBP compared to CRP (Diaconeasa et al., 2015) may cause a metabolic disorder and depressed growth (Vilariño et al., 2009). These tannin effects might extend to the pomace diets not outperforming the BMD-diet despite the near-equivalent performance numbers. ...
This study evaluated effects of feeding low-bush wild blueberry (LBP) and organic American cranberry (CRP) pomaces without or with multienzyme supplement (ENZ) on growth performance, organ weight and plasma metabolites in broiler chickens. Nonenzyme-fed (no-ENZ: n = 1,575) and enzyme-fed (ENZ: n = 1,575) day-old male Cobb500 broilers were placed in floor pens (45 chicks/pen) and allocated to five corn-soybean meal-based diets: a basal diet supplemented with either bacitracin methylene disalicylate (BMD, 55 mg/kg), 0.5 or 1% of CRP or LBP in a 2 × 5 factorial design for 35-day experiment. Body weight (BW), feed intake (FI) and mortality were recorded whereas BW gain (BWG) and feed conversion ratio (FCR) were calculated. Birds were sampled at days 21 and 35 for organ weights and plasma metabolites. There were no interactions between diet and ENZ on any parameter (P > 0.05) and no effect of ENZ on overall (d 0-35) growth performance and organ weights (P > 0.05). Birds fed BMD were heavier (P < 0.05) at d 35 and had better overall FCR than berry-supplemented birds. Birds fed 1% LBP had poor FCR than birds fed 0.5% CRP. Birds fed LBP exhibited heavier liver (P < 0.05) than birds fed BMD or 1% CRP. The highest plasma concentrations of aspartate transaminase (AST), creatine kinase (CK) at d 28 and gamma-glutamyl transferase (GGT) at d 35 were found in ENZ-fed birds (P < 0.05). At d 28, birds fed 0.5% LBP showed higher plasma AST and CK concentrations (P < 0.05). However, CRP feeding resulted in a lower plasma CK level compared with BMD feeding (P < 0.05). The lowest cholesterol level was detected in 1% CRP-fed birds. In conclusion, this study showed no ENZ effects to potentiate berry pomaces on the overall growth performance of broilers (P < 0.05. However, plasma profiles revealed the potential of ENZ to modulate the metabolism of pomace-fed broilers. LBP increased BW during the starter phase, while CRP increased BW during the grower phase.
... In Korean berries, Kim [11] reported a total phenolic composition of 1307.33 ± 9.24 mg GAE/100 g for blackberry, 936.67 ± 2.08 mg GAE/100 g for blueberry and 489.67 ± 2.52 mg GAE/100 g for raspberry. In Romanian berries, blueberries have obtained a higher value of polyphenols with 678 mg GAE/100 g FW, followed by blackberries (about 440 mg GAE/100 g FW) and raspberries with approximately 410 mg GAE/100 g FW [14]. ...
... The highest concentration of tannins was observed in blackberries varieties (112.05 ± 49.9 and 119.64 ± 68.7 mg CAE/g DW), the Ras2 raspberry variety (112.53 ± 9.4 mg CAE/g DW) and the Blu1 blueberry variety (107.24 ± 39.22 mg CAE/g DW), while the rest of the varieties showed lower concentrations. In contrast, Diaconease et al. [14] found the highest tannin values in blueberries (160 mg/100 g), followed by raspberries (120 mg/100 g) and blackberries (around 75 mg/100 g). ...
The objective was to evaluate the antioxidant and biological potential of eight freeze-dried berry varieties of southern Jalisco using in silico and in vitro approaches. Fourteen tentative phenolic compounds were identified in berries by ESI-QToF, including anthocyanins, phenolic acids, flavanols and flavonols. In silico assays of phytochemicals in the berry inhibiting enzymes related to obesity and diabetes showed predicted binding energy interactions (ranging from −5.4 to −9.3 kcal/mol). Among the cultivars, antioxidant potential for DPPH IC50 ranged from 1.27 to 3.40 mg/mL, ABTS IC50 from 2.26 to 7.32 mg/mL and nitric oxide (NO) inhibition IC50 from 4.26 to 11.07 mg/mL. The potential to inhibit α-amylase IC50 ranged from 4.02 to 7.66 mg/mL, α-glucosidase IC50 from 0.27 to 4.09 mg/mL, lipase IC50 from 1.30 to 4.82 mg/mL and DPP-IV IC50 from 1.36 to 3.31 mg/mL. Blackberry cultivars from the southern Jalisco region showed outstanding biological potential compared to other evaluated berries and could be used in the formulation of functional foods in the prevention of noncommunicable diseases.
... In the TTC assay, the blueberry waste had the highest value, 16.47 ± 0.98 μg CE/g, which is a significantly higher value than the other three samples. Diaconeasa et al. [39] reported that blueberry and raspberry contain significantly higher (p < 0.05) TTC content compared to strawberry and blackberry, which is inconsistent with the results of this study. According to Subbiah et al.'s [32] study, Australiangrown fresh blueberries were 7.41 mg CE/g. ...
Berries waste is a major issue in Australia’s annual food wastage, which can reach 7.3 million tonnes. This study assessed the phenolic content and antioxidant potential of four fruit berry wastes, including blueberries (Vaccinium corymbosum), blackberries (Rubus spp.), raspberries (Rubus idaeus), and strawberries (Fragaria spp.), followed by their characterization and quantification. Blueberry wastes were high in phenolic content (total phenolic content: 1.97 ± 0.16 mg GAE/gF.W; total flavonoid content: 220.43 ± 13.15 μg QE/gF.W; total tannins content: 16.47 ± 0.98 μg CE/gF.W), and antioxidant potentials are 2,2′-diphenyl-1-picrylhydrazyl: 2.23 ± 0.17 mg AAE/gF.W; 2,2′-azino-bis-(3-ethylbenzothiazoline-6-sulphonic acid): 1.79 ± 0.09 mg AAE/gF.W; ferric reducing antioxidant power: 68.71 ± 11.11 μg AAE/gF.W (total antioxidant capacity: 1.22 ± 0.03 mg AAE/gF.W). The LC-ESI-QTOF-MS/MS analysis identified 87 compounds from blueberry (57), strawberry (40), raspberry (47), and blackberry wastes (27). Indicated by HPLC quantification, blueberry wastes had higher levels of phenolic acid (syringic acid and coumaric acid) and flavonoid (kaempferol and kaempfero l-3-glucoside). Our study reported that phenolics from berry wastes could be utilized in different food, feed, pharmaceutical, and nutraceutical industries.
... Summary of findings related to HT-containing product consumption and OA in humans (see Table S1 for specific details on sample preparation and characterization of the tested products). Together with pomegranate fruits and strawberries, also blueberries are a rich source of HTs (160 mg GA equivalents per 100 g of fresh weight, as reported by Diaconeasa et al. (2015) [49]) and are widely consumed. Du et al. (2019) [48] performed a randomized, double-blind trial to evaluate whether the regular consumption of freeze-dried blueberries (40 g/day) in 63 obese adults with knee OA might positively affect pain, gait performance, and inflammation. ...

Osteoarthritis (OA) is the most common form of arthritis affecting both the elderly and the middle-aged population. Although various therapeutics have been developed to arrest the structural deterioration of cartilage, the current treatments are limited to delay the progress of OA clinically. Therefore, it is pivotal to study new therapeutic agents for chondroprotection and the prevention of cartilage degeneration. Hydrolyzable tannin (HT)-containing foods aroused considerable interest in recent years for their relevant anti-inflammatory effects. The focus of this scoping review is to provide an overview of the evidence of the therapeutic potential of HTs and their metabolites in preventing or alleviating the course of OA. A broad search of PubMed and Scopus databases on this topic resulted in 156 articles. After the exclusion of reviews and not relevant records, 31 articles were retrieved. Although only some papers did not consider the biotransformation of HTs, most recent studies also have investigated the effect of HT metabolites. Further larger clinical trials, with an in-deep analysis of HT metabolization, are still needed to unravel the potential benefits of these compounds in OA, paving the way towards the development of a dietary strategy for the improvement of pro-inflammatory cytokine-induced chondrocyte dysfunctions and injuries.
... These results are comparable with a previous study that reported a higher TPC in blackberry than raspberry (Diaconeasa et al., 2015). However, this same study reported a higher TPC in blueberry than blackberry (Dia- coneasa et al., 2015), which is different from the results in the present study. ...

Similar results have been found previously where highest ascorbic acid contents were recorded in raspberry compared to all other types of berry samples collected in Korea as well as foreign countries such as Greece and Romania (Pantelidis et al., 2007;Diaconeasa et al., 2015;Lee et al., 2015). It is well known that ascorbic acid is one of the most important vitamins mainly obtained from fruits and vegetables in the diet. ...
... In summary, the antioxidant activities measure by all methods showed high correlations with the phenolic contents than vitamin C for each sample. Such correlations have been reported by other authors for several berry samples in different parts of the world (Pantelidis et al., 2007;Diaconeasa et al., 2015). Antioxidant capacities also somehow showed correlations with the TACs. ...
Aronia, blueberry, Korean raspberry, blackberry, mulberry, and red raspberry fruits cultivated in Korea were evaluated for total phenol content (TPC), total flavonoid content (TFC), total anthocyanin, and ascorbic acid content. All berries were assayed for antioxidant activities determined as 2,2-diphenyl-1-picrylhydrazyl free radical scavenging activity, 2,2'-azino-bis(3-ethylbenzothiazoline)-6 sulphonic acid free radical scavenging activity, and ferric reducing antioxidant power. Individual phenolic compounds in aronia were also identified using high-performance liquid chromatography/quadrupole-time of flight mass spectrometry. TPC, TFC, total anthocyanin, and ascorbic acid contents of the fruit samples ranged from 17.05 to 135.55 mg of gallic acid equivalent/g dry weight (dw), 1.0 to 8.59 mg of rutin equivalent/g dw, 2.55 to 24.43 mg of cyanidin-3-O-glucoside equivalent/g dw, and 3.14 to 19.45 mg of ascorbic acid equivalent/g dw, respec-tively. Aronia and Korean raspberry showed the highest TPC, TFC, and total anthocyanin while red raspberry had the high-est ascorbic acid content. Antioxidant activities showed positive correlations to phenolic and anthocyanin contents suggesting antioxidant activity of berry samples is due to these compounds. Aronia had the highest antioxidant value among fruits.
