Enhancing extraction of betalains from beetroot (Beta vulgaris L.) using deep eutectic solvents: optimization, bioaccessibility and stability

Deep eutectic solvents (DESs) are the next generation of green solvents that are considered for their stability and biocompatibility. This study used 10 different DESs synthesized from choline chloride, alcohols, organic acids and sugars. Red beet betalains were extracted using three conventional solvents and DESs. Characterization experiments of DESs suggested that the electrical conductivity, pH, viscosity, water activity, density and chemical structure were greatly affected by the composition of the hydrogen bond acceptors (HBA) and hydrogen bond donors (HBD). Betacyanin, betaxanthin and total betalain contents ranges were 23.68–702.17, 21.49–467.77, and 45.17–1169.94 mg kg−1, respectively, with choline chloride (ChCl): glucose (Glu) (1:2) giving the highest values. ChCl:Glu was chosen for the optimization process considering the molar ratio (ChC = 1:Glu = 0.75–1.75), water content (15–35%) and temperature (30–60 °C) factors for the central composite design. The optimum conditions were recorded as 1:0.75 molar, 30.83% water content, and 30 °C, respectively. Under optimum conditions, the yields of betalain, betacyanin and betaxanthin were found to be 1192.17 ± 23.63, 738.83 ± 17.87, and 453.34 ± 5.93 mg kg−1, respectively. Bioaccessibility analysis and stability tests were performed on the extracts obtained under optimum conditions. Stability tests revealed that the betalains of red beetroot are less stable in the light than in the dark. Bioaccessibility values for betacyanin, betaxanthin, and betalain were found to be 44.67 ± 1.40, 75.02 ± 1.20, and 56.21 ± 1.33%, respectively. Green extraction of betalains from red beetroot using DES, such as ChCl:Glu, is promising for a strong stabilization and high bioaccessibility of betalains.Graphical

Use of an eco‐friendly preservation technology as a strategy to increase the microbiological shelf‐life of a novel ready‐to‐eat salad containing vegetable by‐products

AbstractThe objective of this investigation was to evaluate different UV‐C irradiation doses in a novel ready‐to‐eat vegetable product containing vegetable by‐products (red beet leaves) and determine the microbiological shelf‐life and quality indicators during refrigerated storage (5 ± 1°C). During processing, no chemical disinfection was carried out and after the packaging step, 3 doses of UV‐C irradiation were applied (CTRL: 0 kJ/m2, L: 1 kJ/m2, M: 4 kJ/m2, and H: 7 kJ/m2) on the vegetable product studied (50% Creola purple lettuce, 25% beet leaves, and 25% arugula). It was observed that the intermediate dose (M) was the most suitable treatment since it could increase in six times its microbiological shelf‐life. Additionally, M was the one that showed the lowest loss of total polyphenols and the one that best maintained the antioxidant capacity (DPPH), probably attributed to the decrease in the activity of deterioration enzyme, PPO and higher ascorbic acid content at day 4. When evaluating % CO2/O2 on headspace of bags, UV‐C treatments reached earlier the dynamic equilibrium. Finally, all UV‐C irradiation treatments were successful against the simulated contamination. In that way, significant reductions of L. innocua and E. coli were found, with differences from up to 2 log cycles during storage. Finally, it can be concluded that UV‐C treatment can increase the microbiological shelf‐life of the novel ready‐to‐eat vegetable product, with quality indicators stabilization.Practical applicationsReady‐to‐eat salads present a short shelf‐life, which hinders their commercialization. As preservation technologies are required, UV‐C irradiation is an eco‐friendly alternative for its preservation as it has the potential to replace traditional disinfection treatments by reducing the water footprint of the total process. Therefore, since the UV‐C treatment is applied in the last step of the process (after packaging the product), microbiological contamination occurring in this type of vegetable products during processing is minimized. However, additional investigation is necessary to assess its suitability for a novel ready‐to‐eat salad containing horticultural by‐products.

Evaluation of confirmatory data following the Article 12 MRL review for myclobutanil.

The applicant Corteva Agriscience submitted a request to the competent national authority in Austria to evaluate the confirmatory data that were identified for myclobutanil in the framework of the MRL review under Article 12 of Regulation (EC) No 396/2005 as not available. To address the data gap related to the lack of information on the triazole derivative metabolites (TDMs), new residue trials analysing for TDMs were submitted on apples, grapes, strawberries, tomatoes and melons. Following the assessment of the submitted data, EFSA concluded that Article 12 confirmatory data gaps are considered addressed for pome fruits, grapes, cucurbits with inedible peel, strawberries and tomatoes. The new information provided required the assessment of consumer exposure to TDMs, which identified no consumer intake concerns for the crops under consideration. No information was provided to address the Article 12 confirmatory data referred to in Regulation (EU) 2020/770 for blackberries, gooseberries, bananas, aubergines/eggplants, lamb's lettuces/corn salads, beans (with pods), globe artichokes, hops, sugar beet roots and products of animal origin. For these commodities, the existing EU MRL could be lowered to the enforcement limit of quantification (LOQ). For kaki/Japanese persimmon and azararoles/mediterranean medlars, the existing EU MRL is set on the basis of Codex MRL in pome fruits. The applicant did not request maintaining a Codex MRL in these commodities, but should risk managers decide otherwise, the Article 12 data gap is considered addressed for kaki/Japanese persimmon while for azaroles/Mediterranean medlars, a risk management decision might be required. No consumer intake concerns were identified.

ANALYSIS OF DIFFERENCES IN THE EFFECTIVENESS OF GIVING RED BEET JUICE (BETA VULGARIS L) AND CUCUMBER JUICE (CUCUMIS SATIVUS) ON REDUCING BLOOD PRESSURE IN HYPERTENSIVE PATIENTS

Hypertension is a serious health issue worldwide, leading to cardiovascular diseases like heart attack, heart failure, stroke, and kidney disease. To prevent hypertension, a combination of pharmacological and non-pharmacological methods is necessary, including adopting a healthy lifestyle and consuming herbal plants. For instance, cucumber juice therapy and a mix of beetroot and pineapple juice are commonly used. This study aims to compare the effects of red beet juice and cucumber juice on the blood pressure of hypertensive patients in Drien Tujoh Village, Tripa Makmur District, Nagan Raya Regency in 2023. The research involved 30 hypertensive patients over 35 years old, divided into two groups. The results showed a significant difference in blood pressure before and after the intervention with beetroot juice and cucumber juice. This indicates that both interventions can help lower blood pressure in hypertensive patients.

Математическое обеспечение информационно-управляющей системы для хранения продукции с ограниченным сроком хранения

The work presents a solution to the problem of developing mathematical support for an information and control system for storing products with a limited shelf life using the example of storing sugar beets in field conditions and in heaps at sugar factories based on experimental experiments published in the open press data. An end-to-end ranking of methods for storing root crops was carried out, starting with a root lying separately on the field (rank 0.1 points), from simple windrows and heaps (rank 0.2 points) to specialized root storage and ventilated piles covered with special bactericidal coatings with reflective and protective properties (rank 4 points). An end-to-end ranking of mechanical damage to sugar beet roots has been implemented, starting from 1 point (the root crop is practically undamaged) to 0.1 point (fragments and tails). The studied hybrids were ranked according to sugar content. Based on the rankings, taking into ac-count storage time and temperature, mathematical models (mm) of the dependence of technological indica-tors of beet raw materials, including losses of beet mass and sucrose, on storage parameters were built for each study. Extensive computational experiments were per-formed using an interactive identification and optimization system (isio), which is based on a genetic algorithm and the Hooke Jeeves nonlinear programming method. The errors of the developed models do not exceed the errors of the experimental data used to construct them.

Inoculum density-dependent, additive effectiveness of fungicides or biofungicides with cultivar resistance for integrated management of Cercospora leaf spot on beet greens

Cercospora leaf spot, caused primarily by Cercospora beticola, is common on red beet wherever this vegetable crop is grown. The effectiveness of a conventional (propiconazole rotated with azoxystrobin) and an organic biofungicide (Bacillus amyloliquefaciens mixed with copper octanoate) program were tested on four cultivars of beet that differed in susceptibility. Three inoculum densities were established by inoculating a 1-m portion of one row, allowing conidia to splash to the adjacent row, and not inoculating the remainer of the plot. Foliar severity was reduced by both fungicide programs compared to the water-treated control, but the conventional fungicides were more effective in the high inoculum area than the organic fungicides. The conventional fungicides also increased the fresh weight of healthy leaves compared to the water control, but the organic fungicides did not differ from the other two treatments. All cultivars except the most resistant one, Bull's Blood, had greater healthy weights in 2022 when the inoculum density was lower than in 2021. Cultivars sorted in the same order of susceptibility regardless of fungicide program. In all treatments, mean weight of diseased individual leaves was greater than healthy leaves. Partial cultivar resistance and fungicides or biofungicides had additive effects for integrated management of Cercospora leaf spot on red beet.

Debottlenecking the L-DOPA 4,5-dioxygenase step with enhanced tyrosine supply boosts betalain production in Nicotiana benthamiana.

Synthetic biology provides emerging tools to produce valuable compounds in plant hosts as sustainable chemical production platforms. However, little is known about how supply and utilization of precursors is coordinated at the interface of plant primary and specialized metabolism, limiting our ability to efficiently produce high levels of target specialized metabolites in plants. L-Tyrosine is an aromatic amino acid precursor of diverse plant natural products including betalain pigments, which are used as the major natural food red colorants and more recently a visual marker for plant transformation. Here, we studied the impact of enhanced L-tyrosine supply on the production of betalain pigments by expressing arogenate dehydrogenase (TyrA) from table beet (Beta vulgaris, BvTyrAα), which has relaxed feedback inhibition by L-tyrosine. Unexpectedly, betalain levels were reduced when BvTyrAα was coexpressed with the betalain pathway genes in Nicotiana benthamiana leaves; L-tyrosine and 3,4-dihydroxy-L-phenylalanine (L-DOPA) levels were drastically elevated but not efficiently converted to betalains. An additional expression of L-DOPA 4,5-dioxygenase (DODA), but not CYP76AD1 or cyclo-DOPA 5-O-glucosyltransferase, together with BvTyrAα and the betalain pathway, drastically enhanced betalain production, indicating that DODA is a major rate-limiting step of betalain biosynthesis in this system. Learning from this initial test and further debottlenecking the DODA step maximized betalain yield to an equivalent or higher level than that in table beet. Our data suggest that balancing between enhanced supply ("push") and effective utilization ("pull") of precursor by alleviating a bottleneck step is critical in successful plant synthetic biology to produce high levels of target compounds.

Dissipation behaviours, residues, and health risk of six herbicides in sugar beets under field conditions

This study established a residue detection method based on the QuEChERS pre-treatment method and combined it with high-performance liquid chromatography–tandem mass spectrometry to test six herbicides (metamitron, clopyralid, desmedipham, phenmedipham, ethofumesate, and haloxyfop-p-methyl) in sugar beet plants, soil, and roots. The degradation dynamics and terminal residues of each herbicide in sugar beets were analysed. Finally, the dietary risks of various herbicides in sugar beets were evaluated based on the dietary structure of Chinese people, and the risk quotient values were below 100%. Using this detection method, all reagents exhibited good linearity (0.9724 ≤ R2 ≤ 0.9998), The limit of quantification (LOQ) ranged from 0.01 to 0.05 mg/L, the matrix effect ranged from −1.2% to −50%, the addition recovery rate ranged from 77.00% to 103.48%, and the relative standard deviation ranged from 1.61% to 16.17%; therefore, all indicators of this method met the residue detection standards. Under field conditions, the half-lives (t1/2) ranged about 0.65 ∼ 2.96 d and 0.38 ∼ 27.59 d in sugar beet plants and soil, respectively. All herbicides were easily degraded in sugar beet plants and soil (t1/2 < 30 d). The terminal residue amounts in the beet plants, soil, and roots ranged from < LOQ to 0.243 mg/kg. The dietary risk assessment of each pesticide was conducted based on the residual median of the terminal residues and the highest residual values on the edible part of the beetroot. The chronic exposure risk quotient (RQc) and acute exposure risk quotient (RQa) values were < 100%, indicating that the residue of each pesticide in beetroot posed low risks to consumers in China at the recommended dosage.

Influence of Plant-Based Structuring Ingredients on Physicochemical Properties of Whey Ice Creams

The dairy industry is actively seeking new applications for various types of whey. One promising direction is the development of nutritious ice cream, using a blend of different whey proteins. However, the production of whey ice cream is hindered by the occurrence of quality issues, primarily stemming from a low content of solids, particularly fat and protein. The development of natural components with distinctive technological attributes, such as the ability to bind excess moisture, enhance foaming properties, and replicate the taste of milk fat, is of significant relevance in food science. In this work, we investigated the influence of plant-based structuring ingredients on the viscoelastic characteristics of whey-based ice creams. Notably, mixes such as 0.4% Vianoks C45 + 0.75% oat β-glucan, 0.4% Vianoks C45 + 0.5% yeast β-glucan, and 0.4% Vianoks C45 + 3% whey protein complex + 10% vegetable purée from table beet have been proven to be effective stabilizing compositions. However, attempts to combine the whey protein complex with other types of vegetable purées like zucchini and broccoli did not yield satisfactory results. It has also been found that β-glucan from the yeast Saccharomyces cerevisiae and κ-carrageenan, a component of the Vianoks C45 stabilization system, forms a robust gel within the system. Analysis of the aqueous phase in whey-based ice creams revealed a consistent correlation between water activity, surface tension, and rheological behavior. Finally, the ice creams that exhibited the best viscoelastic characteristics also had the best sensory attributes.

Metabolite profiling of triterpene saponins from different red beetroot cultivars using ultra-high performance liquid chromatography high-resolution mass spectrometry

In recent years, there has been increasing interest in the use of red beets as a valuable source of bioactive compounds. Although saponins may be responsible for the pharmacological and nutraceutical activities of red beets, information on the saponin composition of various red beet cultivars is very limited, and the saponin profiles remain to be fully elucidated. Here, we profiled triterpene saponins from the flesh and skin of different red beetroot cultivars, whose names of Polish cv. are Bonel, Chrobry and Nochowski. In addition, the total triterpene saponin contents in cultivars Bonel, Chrobry, Nochowski and in their various root parts were determined. Triterpene saponins isolated from the skin and flesh of different red beetroot cultivars were qualitatively profiled using two high-performance liquid chromatography systems (HPLC-ESI-IT MS and UPLC-HESI-Q-Orbitrap MS). The total triterpene saponin contents in different cultivars were analyzed using high-performance liquid chromatography-tandem mass spectrometry. In total, 40 triterpene saponins were tentatively identified, and among them, 5 compounds were potentially new saponins, not previously reported in red beets. These saponins are new to red beets and were reported in B. vulgaris for the first time. The analyzed cultivars were different in terms of their total saponin content. The results of our study indicated that the variation in the composition of saponins depended on the red beet cultivars and part of the roots. Higher concentrations of these compounds were found in the skins than in the flesh of roots. We developed an analytical strategy to discover and identify triterpene saponins from B. vulgaris L. using a combination of techniques to detect the comprehensive fragmentation pathways of the saponins present at low concentrations in plant material.

(206) Strategies of Nitric Oxide Augmentation for PDE5 Inhibitors

Abstract Introduction Erectile function and endothelial functions are closely related entities. Nitric oxide NO regulates circulation and microcirculation involved in erection.NO concentration is reduced with aging, diabetes, environment pollution smoking, obesity, inflammation, high prolactin, low testosterone oxidative stress and atherosclerosis. Many of erectile dysfunction patients are PDE5 inhibitor resistant. Strategies to enhance NO expression, can be employed to convert treatment resistant patient into responder. Objective Employ every possible mechanism to augment nitric oxide expression. Greater base line nitric oxide better would be PDE5 inhibitor respose. Methods Internet search was made on various website including pub med, science direct, google scholars using key words like erection, erectile dysfunction, nitric oxide, l arginine, oxidative stress, antioxidant, NOS, endothelial dysfunction, atherosclerosis and etc. This was followed by literature study on given topic. Results Efficacy of PDE 5 inhibitor in ED treatment is 70%. NO concentration decline to 50% by age of 40 and is only 15% at age 60. Humming can increase nasal NO level up to 15 time. Conclusions NO regulates endothelial function, vasodilatation, platelet aggregation inhibition, free radical scavenging, testosterone synthesis and neuronal protection. Study of mechanism of NO production provides, strategies for its enhancement. L arginine, L citrulline, serve as substrate and vitamin C, tetrahydrobiopterin (BH4) act as co factors in production of NO. Endothelial nitric oxide synthase e NOS, neuronal nitric oxide synthase n NOS are major enzymes act involved in synthesis. Oxygen is required for NO synthesis process. Supplementation of substrate and cofactors help increase NO levels. Oxygen availability can be increased through exercise and raising hemoglobin level. Reactive oxygen species ROS convert NO into bioinactive peroxynitrite which itself is ROS. Oxidative stress can cause endothelial nitric oxide synthase uncoupling. Consequently eNOS start producing ROS. This causes oxidation of NOS and as well as of cofactor like BH4 and vitamin C. ROS also increase level of methylarginines. Antioxidant used to neutralize ROS include Co Q10, alpha lipoic acid, flavonoids, bioflavonoids poly phenols, pycnogenol, resveterol, fulvic acid and etc. Second mechanism NO production is from dietary nitrates. Nutritional nitrates are converted into nitrite by oral anaerobic bacteria’s. Nitrate rich foods like beet root or spinach are added to enhance nitrate based NO. Nitric oxide thus produced is used for vasodilatation of penile vessels as well sinuses of corpus cavernousm. Apart from that it inhibits uncoupling of NOS. This support L arginine based mechanism of NO production. Nitroglycerin or minoxidal act as NO donors. These agents can be used locally at glans penis to augment NO availability. Bee breathing is maneuver in which humming sound vibrates nasal sinus increasing NO production up to 15 folds. Inhaled NO act as bronchodilator which increase lung capacity leading to higher blood oxygen concentration. Various NO enhancement strategies thus applied, may convert non responder PDE5 inhibitor to responders. Disclosure No.

Broccoli, Amaranth, and Red Beet Microgreen Juices: The Influence of Cold-Pressing on the Phytochemical Composition and the Antioxidant and Sensory Properties.

The aim of this study was to analyze in detail the phytochemical composition of amaranth (AMJ), red beet (RBJ), and broccoli (BCJ) microgreens and cold-pressed juices and to evaluate the antioxidant and sensory properties of the juices. The results showed the presence of various phenolic compounds in all samples, namely betalains in amaranth and red beet microgreens, while glucosinolates were only detected in broccoli microgreens. Phenolic acids and derivatives dominated in amaranth and broccoli microgreens, while apigenin C-glycosides were most abundant in red beet microgreens. Cold-pressing of microgreens into juice significantly altered the profiles of bioactive compounds. Various isothiocyanates were detected in BCJ, while more phenolic acid aglycones and their derivatives with organic acids (quinic acid and malic acid) were identified in all juices. Microgreen juices exhibited good antioxidant properties, especially ABTS•+ scavenging activity and ferric reducing antioxidant power. Microgreen juices had mild acidity, low sugar content, and good sensory acceptability and quality with the typical flavors of the respective microgreen species. Cold-pressed microgreen juices from AMJ, RBJ, and BCJ represent a rich source of bioactive compounds and can be characterized as novel functional products.

Variations in rhizosphere soil dominant and pathogenic flora improve boron-efficient Beta vulgaris L. yield under boron deficit

Boron (B)-efficient sugarbeet can potentially adapt better to the B deficient soil environments, however the characteristics of root yield or quality and rhizosphere soil microbial dynamics associated with B-efficient beet roots are extremely understudied. This study aimed to clarify the root yield characteristics and rhizosphere microbial response of B-efficient sugarbeet variety under B deficiency. Pertinently, the findings of this study will contribute to the reduction of B resource consumption and cleaner production in sugarbeet planting management. The study utilized two sugarbeet varieties with different B utilization propensities and subjected them to normal and B deficient field conditions. Results demonstrated a reduction in the yield quality of both varieties under B deficiency, but the B-efficient variety exhibited a smaller reduction. Boron deficiency reduced the species richness and diversity of the rhizospheric microbial community, decreasing the relative abundance of Actinobacteriota, Acidobacteria, while increasing that of Proteobacteria, Chloroflexi and the pathogenic fungus Fusarium. The proportion of dominant bacterial was severely reduced in B-inefficient varieties (0.86%) compared to B-efficient varieties (0.14%). The efficient variety displayed higher species richness of rhizospheric soil fungi and a higher abundance and proportion of dominant flora, i.e., Bacillus and Actinobacteria, albeit lower abundance of the pathogenic fungi Mortierellomycota and Rhizoctonia. These advantages allowed B-efficient sugarbeet variety to maintain higher yield levels under B deficit. Overall, under B-deficient conditions, B-efficient variety of sugarbeet was less limited than B-inefficient one, and its rhizosphere microbial communities were more conducive to sugarbeet yield in terms of composition and function. Succinctly, this study revealed the advantages of rhizosphere soil microorganisms associated with B-efficient beet under B-deficient environments and provided the theoretical basis for reducing boron fertilizer application to protect the ecosystem and realize green and clean agricultural production, particularly of sugar beet.

Dependence of table beet yield on different doses of compost in organic farming

The paper presents the experimental study results on the effect of different doses of BIAGUM compost on the yield of Dvusemiannaya TSHA table beet variety. The compost was produced from fermented poultry manure. The table beet was grown on sod-podzolic soil on carbonate loam in the frame work of a six-field biology-based crop rotation. No protective agents were used. Mechanical and manual weed control was applied instead. The precursor on the experimental plots was potatoes fertilized with BIAGUM compost in an amount of 4 t∙ha–1 (N = 80 kg∙ha–1) in 2021. The average biological yield of table beet roots in 2022 in the control variant without compost (variant 1) was 24.94 t∙ha–1, in the variant with the compost application dose of 4 t∙ha–1 (N = 80 kg∙ha–1) (variant 2) – 29.40 t∙ha–1, in the variant with the compost application dose of 8 t∙ha–1 (N = 160 kg∙ha–1) (variant 3) – 31.28 t∙ha–1. The study revealed that the compost application (variants 2 and 3) increased the average yield by 17.88 and 25.41 % compared to variant 1, respectively. There were statistically significant differences between the variant 1 and variants 2 and 3: the LSD for the 5 % significance level was 2.42 t∙ha–1. The compost application in variants 2 and 3 increased the average mass of table beet roots by 30.7 and 33 %, respectively, against the variant 1 (control). The share of substandard roots in the total yield for these variants also increased. In all experiment variants, the nitrate content in the table beet roots did not exceed the allowable value of 1400 mg/kg. The experiment findings indicate a positive effect of BIAGUM compost application in the set doses on the table beet yield cultivated in organic farming.

Drying and characterization of red beet color liquid process waste to develop a novel bulking agent

For cleaner and sustainable production, industrial food waste reuse studies are great of importance. In this study, to develop a novel bulking agent from the liquid wastes of colorant production processes obtained from red beet extract (RBW), an optimization study with an 18-point experimental point was performed in a pilot spray dryer by using maltodextrin as a carrier material for drying. The spray drying inlet temperature (120–140 °C) and the ratios of carrier agent (10%–25%) and liquid waste (75%–90%) in the feed solution were independent variables. Optimization responses were drying yield (44.4–86.6%) and moisture content (1.39–3.89 g/100 g). In addition, physicochemical (water activity, color, pH), particle size distribution, and various powder characteristics of the samples were investigated. Significant models for responses were determined (P < 0.05). The optimum conditions (Desirability: 0.876) for RBW drying were determined and validated as 120 °C spray dryer inlet temperature, and feed solution containing 90% RBW and 10% maltodextrin in dry matter. As a result, powders obtained from RBW have the potential to be used as a bulking agent in food formulations due to their composition and low moisture content, water activity and drying yield (>80.0%). According to our results, it may be possible to prevent the release of RBW which has high COD and BOD values and to decrease the production and waste treatment costs of the colorant industry. However, the limitations of the novel bulking agent as residual pigments and total ash content should be considered for further food applications.
