Varietal Differences in Juice, Pomace and Root Biochemical Characteristics of Four Rhubarb (Rheum rhabarbarum L.) Cultivars
No full textThe complex evaluation of varietal biochemical differences in rhubarb juice, pomace and roots is highly useful to develop an efficient processing technology. Research was carried out to compare four rhubarb cultivars (Malakhit, Krupnochereshkovy, Upryamets and Zaryanka) in terms of the quality and antioxidant parameters of juice, pomace and roots. The laboratory analyses showed a high juice yield (75–82%) with a relatively high content of ascorbic acid (125–164 mg L−1) and other organic acids (16–21 g L−1). Citric, oxalic and succinic acids accounted for 98% of the total acids amount. The juice of the cultivar Upryamets demonstrated high levels of the natural preservatives sorbic (36.2 mg L−1) and benzoic acids (11.7 mg L−1), which are highly valuable in juice production. The juice pomace proved to be an excellent source of pectin and dietary fiber, whose concentrations reached 21–24% and 59–64%, respectively. The total antioxidant activity decreased according to the following sequence: root pulp (161–232 mg GAE g−1 d.w.) > root peel (115–170 mg GAE g−1 d.w.) > juice pomace (28.3–34.4 mg GAE g−1 d.w.) > juice (4.4–7.6 mg GAE g−1 f.w.), suggesting that root pulp is a highly valuable antioxidant source. The results of this research highlight the interesting prospects of the complex rhubarb plant processing for the production of juice, containing a wide spectrum of organic acids and natural stabilizers (sorbic and benzoic acids), dietary fiber and pectin (juice pomace) and natural antioxidants (roots)

Selenium: Prospects of Functional Food Production with High Antioxidant Activity
No full textThe essentiality of selenium for mammals including human beings, its powerful
antioxidant properties, and synergism with other natural antioxidants elicit inten sive investigations in agricultural and medicinal crop products with high levels of
selenium, phenolics, and other antioxidants. The present chapter demonstrates the
most interesting results of such studies revealing high possibilities of selenium
biofortification, increase in soil selenium bioavailability via arbuscular mycorrhi zal fungi (AMF) and Se-dependent bacteria application, and discovery of new
medicinal plants – Se accumulators with high antioxidant activity. Moreover,
special attention has been paid to the production of functional food with artifi cially high selenium and antioxidant content: sprouts and microgreens fortified
with selenium, medicinal mushrooms
The Effect of One-Year Seed Spaceflight Storage on Yield, Biochemical and Mineral Characteristics of Mature Leafy Vegetables Belonging to Brassicaceae, Apiaceae and Asteraceae Families
No full textSpaceflight is known to produce genetic changes in seeds, usually accelerating aging,
though species and varietal differences have been poorly investigated. Comparisons were carried
out in terms of yield, biochemical characteristics and mineral composition between mature plants
grown from seeds subjected to a one-year spaceflight, belonging to Brassicaceae (Brassica juncea
and Eruca sativa), Apiaceae (Anethus graveolens, and Coriandrum sativum), and Asteraceae (Lactuca
sativa, six cultivars) families, and non-treated control. Among the studied species, only Brassica
juncea and Eruca sativa demonstrated a growth stimulation effect caused by seed spaceflight, while
significant growth inhibition was recorded in Apiaceae plants and three cultivars of Lactuca sativa L.
No differences in the total antioxidant activity (AOA), polyphenol and ascorbic acid content were
detected between ‘space-treated’ and control plants. On the contrary, significant decrease in proline
accumulation and increase in malonic dialdehyde and photosynthetic pigments levels were shown
by Brassicaceae species. The effect of long-term seed spaceflight on the mineral composition of
mature plants was reflected in the inhibition of accumulation of all 24 elements analyzed in Apiaceae
plants, except for Se, whose concentration was higher in all ‘space-treated’ plants compared to the
control. Spaceflight seed storage increased V levels in lettuce and decreased Na accumulation in all
the investigated species. The results reveal species-dependent changes in the accumulation of macro-,
micro- and toxic elements in Apiaceae, Brassicacea, and Asteraceae representatives due to spaceflight
seed storage. The detected differences in plant elemental composition between ‘space’ treatment and
control partly explain the corresponding yield gap and suggest a relationship between mineral status
and adaptability. The highest beneficial effect of spaceflight seed storage on yield was recorded in
Eruca sativa cultivar, Rusalochka
Biochemical Characteristics and Elemental Composition Peculiarities of Rheum tataricum L. in Semi-Desert Conditions and of European Garden Rhubarb.
No full textBiochemical and mineral peculiarities of plants inhabiting desert and semi-desert ar eas may provide important information about the mechanism of their adaptability and reveal the
prospects of their utilization. Rheum tataricum L., known for its high tolerance to drought, salin ity, and nutritional deficiency, is the least studied species of wild rhubarb. Using biochemical
and ICP-MS analysis, the antioxidant status and mineral composition of R. tataricum were deter mined. Extremely high levels of antioxidant activity (148–155 mg GAE g−1 d.w.), polyphenols
(24.6–25.1 mg GAE g−1 d.w.) and carotenoids (1.94 mg-eq β-carotene g−1 d.w.) were revealed in
roots, proline in leaves (71.1 ± 6.2 mg kg−1 d.w.) and malic acid in stems (3.40 ± 0.50 mg g−1 d.w.).
Compared to garden rhubarb, R. tataricum demonstrated significant root–leaves translocation of Li,
Se, Si, and Mo, known to participate in plant antioxidant defense. Under high levels of Ca, Na, Mg,
Fe, Cr and Si in soil, R. tataricum demonstrated the ability to significantly increase the accumulation
of these elements in roots, showing a hyperaccumulation ability for Sr. The first broad picture of
R. tataricum biochemical and mineral characteristics in semi-desert habitat and its nutritional value
indicate the prospects of R. tataricum utilization in plant breeding, medicine, and nutrition
