“…This conclusion is consistent with the work of a number of scientists. For example, scientists from Portugal have shown that it is the characteristics of the variety that significantly affect the chemical composition and sensory profile of blackberries, and not the method of organic or traditional farming [2]. Researchers from Oregon noted that the amount of sugars is mainly influenced by the variety [3], our experience also confirmed this (96% of the variation in the trait is due to the influence of the variety).…”

“…Fruiting, as a rule, occurs on the shoots of the second year, after which they die off [1]. Currently, consumer demand for blackberries is growing, due to the fact that a number of studies have shown it as a source of biologically active substances with high antioxidant activity [2][3][4][5]. In Russia, blackberries bear fruit later than traditional berry crops, and, therefore, they can occupy a niche in the supply chain of seasonal berries in the domestic market.…”

Blackberry is a berry culture of the genus Rubus L., which is just beginning to spread in Russia. At the moment, the only domestic variety has been registered, in connection with which there is a need to study foreign varieties as donors of valuable traits. The aim of the study is to assess the influence of varietal characteristics on the quantitative traits of blackberries for further breeding. The article discusses eight varieties of blackberries ('Karaka Black', 'Natches', 'Loch Tay', 'Columbia Star', 'Ark Prime Freedom', 'Black Gem', 'Black Magic', 'Heaven Can Wait'), which were grown in the Rostov region (Russia). To determine the effect, the method of one-way statistical analysis was used. High proportions of factorial influence on berry weight (84%), berry length (81%), amount of sugars (96%), average number of drupes per fruit (76%), average number of replacement shoots (80%), total length of replacement shoots were revealed. (77%), potential number of cuttings from one bush (77%), number of fruits on the lateral (64%), length (67%) and width of the central leaflet (47%), length of the petiole (54%), yield (60% ). No significant influence of the cultivar on the thickness of the petiole, the number of leaves and the average height of the replacement shoots was found. Since the characteristics of a variety make a significant contribution to the variability of traits, a number of varieties with a high or low value of the variable for a trait can become their donors.

“…In this study, few correlations were found between sensory descriptors and higher presence of bioactive compounds (polyphenols and anthocyanins), except for a decreased intensity of salted taste. The multivariate analyses (e.g., PCA or PLS regression) are increasingly used in the sensory science in the attempt of highlighting the degree of contribution of each interdependent sensory attribute to the overall variability of data, or assessing the correlation between the sensory attributes and the analytical data [99][100][101][102][103][104].…”

Sensory Profile, Shelf Life, and Dynamics of Bioactive Compounds during Cold Storage of 17 Edible Flowers

In this study, 17 edible flowers (Allium ursinum L., Borago officinalis L., Calendula officinalis L., Centaurea cyanus L., Cichorium intybus L., Dianthus carthusianorum L., Lavandula angustifolia Mill., Leucanthemum vulgare (Vaill.) Lam., Paeonia officinalis L., Primula veris L., Robinia pseudoacacia L., Rosa canina L., Rosa pendulina L., Salvia pratensis L., Sambucus nigra L., Taraxacum officinale Weber, and Tropaeolum majus L.) were investigated to assess their sensory profile at harvest and their shelf life and bioactive compounds dynamics during cold storage. The emerging market of edible flowers lacks this information; thus, the characteristics and requirements of different flower species were provided. In detail, a quantitative descriptive analysis was performed by trained panelists at flower harvest, evaluating 10 sensory descriptors (intensity of sweet, sour, bitter, salt, smell, specific flower aroma, and herbaceous aroma; spiciness, chewiness, and astringency). Flower visual quality, biologically active compounds content (total polyphenols and anthocyanins), and antioxidant activity (FRAP, DPPH, and ABTS assays) were evaluated both at harvest and during storage at 4 °C for 14 days to assess their shelf life. Generally, species had a wide range of peculiar sensory and phytochemical characteristics at harvest, as well as shelf life and bioactive compounds dynamics during postharvest. A strong aroma was indicated for A. ursinum, D. carthusianorum, L. angustifolia, and L. vulgare, while B. officinalis and C. officinalis had very low values for all aroma and taste descriptors, resulting in poor sensory profiles. At harvest, P. officinalis, R. canina, and R. pendulina exhibited the highest values of polyphenols (884–1271 mg of gallic acid equivalents per 100 g) and antioxidant activity (204–274 mmol Fe2+/kg for FRAP, 132–232 and 43–58 µmol of Trolox equivalent per g for DPPH and ABTS). The species with the longest shelf life in terms of acceptable visual quality was R. pendulina (14 days), followed by R. canina (10 days). All the other species lasted seven days, except for C. intybus and T. officinale that did not reach day 3. During cold storage, the content of bioactive compounds differed, as total phenolics followed a different trend according to the species and anthocyanins remained almost unaltered for 14 days. Considering antioxidant activity, ABTS values were the least variable, varying in only four species (A. ursinum, D. carthusianorum, L. angustifolia, and P. officinalis), while both DPPH and FRAP values varied in eight species. Taken together, the knowledge of sensory profiles, phytochemical characteristics and shelf life can provide information to select suitable species for the emerging edible flower market.

“…24 Also, agricultural practices which may vary across geographic regions may influence phenolic composition; organic practices have been shown to yield blackberries with higher phenolic content than conventional farming practices. 25 The wide variability in flavonoid composition in berries and their processed forms should be considered in clinical studies, especially in the interpretation of effects on clinical outcomes.…”
