Ginger Rhizome Research Articles

Levels of elements in selected food substances that support usage in the management and treatment of erectile dysfunction.

The use of fruits and vegetables for the management and treatment of erectile dysfunction has gained popularity due to the cheaper cost, accessibility and perceived absence of side effects. Much of the work done on plant-based aphrodisiacs has focused on the phytochemistry of secondary metabolites. This work sought to analyze selected fruits and vegetables that are commonly used in the management of erectile dysfunction in Ghana and quantify the levels of some micro- and macro-elements necessary for good penile health in order to determine the usefulness or otherwise of the selected produce. Energy-dispersive X-ray fluorescence spectroscopy was used to detect and quantify the levels of potassium (K), calcium (Ca), selenium (Se), magnesium (Mg), iron (Fe), and zinc (Zn) in carrot roots, cucumber fruit, garlic bulb, ginger rhizome, nutmeg fruit, sweet potato tuber, tiger nut tuber and watermelon fruit. The analysis revealed the presence of K, Ca, Mg, Fe and Zn. Levels of Se were below detection. The concentration of K was the highest in each of the food substances. However, in terms of recommended daily allowance, Mg had the highest contribution. Cucumber fruit and the rind of watermelon fruit had the highest levels of micro- and macro-elements implicated in erectile dysfunction. The potential use of these foods to treat and manage erectile dysfunction may not only be due to the presence of phytochemicals alone but also the presence of significant levels of micro- and macro-elements required for good penile health.

Drying kinetics and thermo-economic analysis of drying hot water blanched ginger rhizomes in a hybrid composite solar dryer with heat exchanger

This research aimed to examine the need of adding hot water blanching pre-treatment on the drying of ginger rhizomes using a hybrid solar-dryer with paraffin liquid as thermal storage infused into a copper tube to form a compact heat exchanger. Blanching duration quickened the drying rate of the ginger rhizomes and the average drying rate for blanching at 90 s, 60 s, 30 s and un-blanched ginger varied between 0.0147 kg/h to 0.0245 kg/h at a sensible heat ratio of 4.12 × 10−5 to 2.53 × 10−3. The optimal drying rate varied from 0.01161 kg/h to 0.0263 kg/h for all treatment at a collector temperature range of 39.5 °C–40.5 °C and collector efficiency range of 14.3%–30%. The logarithmic model better predicted the drying kinetics of un-blanched and blanching for 30 s with an R2 value of 0.9875 and 0.97247 respectively while the modified Henderson and Pabis model better predicted drying of blanched ginger rhizomes at 60 s and 90 s with R2 values of 0.96252 and 0.98188 respectively. Using the hybrid solar dryer instead of artificial dryers with fossil energy sources can save about $75.731 to $757.31 of the running cost as the usage increased from 10 to 100%. The payback period decreased from 2.88 years to 0.31 years as the rate of usage increased from 10 to 100%. Using the presented solar dryer instead of coal, diesel or grid base electricity can prevent 15.96 to 186, 7.62 tones of CO2 from entering the atmosphere. The earned carbon credit if the dryer is to be powered by coal, diesel or grid base electricity were $ $6245364, $27080.52, and $231.45 per year respectively which can be used to compensate other non-renewable energy sources deployed within an energy enterprise.

Certificación de la calidad bactericida del aceite Kion (Zingiber officinale) para la exportación al mercado estadounidense

Zingiber officinale Rosc. known as ginger (known as kion in Peru), belonging to the Zingiberaceae family, it is made up of about forty genera. It is an important culinary spice known for its long usefulness as a flavoring agent. The plant is native to warm tropical climates. Apart from culinary uses, ginger and its main components have beneficial medicinal properties, such as a medicine to combat diabetes, obesity, diarrhea, allergies, pain, fever, rheumatoid arthritis, inflammation and various forms of cancer. Tumors induced in the intestine, breast, ovaries, pancreas, liver, and cardiovascular disorders have been effectively treated in animal models with biologically active constituents of ginger. The multiple properties of the essential oil of the ginger rhizome have made Peru a potential export country. For 2011, more than 687 million dollars were collected and imported to more than 152 countries in the world. However, to continue opening doors in the market, it is important to certify your products, which in this work corresponds to ginger oil as a bacteriological agent. In this sense, a Peruvian oil was physicochemically analyzed and its antimicrobial potential against various strains was determined. The results show that ginger oil showed bactericidal activity at all oil concentrations tested, being more effective at high concentrations than low concentrations. According to the halo of action, kion oil presented greater microbial activity against Salmonella aureus, followed by Streptococcus pyogenes and Xanthomonas horturum.

PENGGUNAAN FILTRAT RIMPANG JAHE MERAH (Zingiber officinale var. Rubrum) TERHADAP HAMA ULAT BAWANG MERAH (Spodoptera exigua H.)

Spodoptera exigua H. is a pest on shallot plants. S. exigua pest control is usually performed using synthetic insecticides. However, its use can cause negative impacts on humans and the agricultural environment. Therefor, it needs the alternative insecticides that are safer and environmentally friendly such as Zingiber officinale var. Rubrum. The purpose of this research was to obtain the effective concentration of red ginger rhizome filtrate to control the pest Spodoptera exigua H. The research was conducted at the experimental farm of the Faculty of Agriculture, Riau University from September to November 2019. Experiments were carried out using a completely randomized design (CRD) with 5 treatments and 4 replications. The red ginger rhizome filtrate concentration treatment used was 0 ml.l-1 water, 20 ml.l-1 water, 40 ml.l-1 water, 60 ml.l-1 water, dan 80 ml.l-1 water. The results showed that the concentration of red ginger rhizome filtrate 60 ml.l-1 water could control pests S. exigua and could cause total mortality of 82,50% with an initial death time of 7 hours and lethal time 50 of 40,25 hours.

Biosynthesis, Characterization, and Augmented Anticancer Activity of ZrO2 Doped ZnO/rGO Nanocomposite.

Fabrication of ZnO nanoparticles (NPs) via green process has received enormous attention for its application in biomedicine. Here, a simple and cost-effective green route is reported for the synthesis of ZrO2-doped ZnO/reduced graphene oxide nanocomposites (ZnO/ZrO2/rGO NCs) exploiting ginger rhizome extract. Our aim was to improve the anticancer performance of ZnO/ZrO2/rGO NCs without toxicity to normal cells. The preparation of pure ZnO NPs, ZnO/ZrO2 NCs, and ZnO/ZrO2/rGO NCs was confirmed by transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), photoluminescence (PL), and dynamic light scattering (DLS). XRD spectra of ZnO/ZrO2/rGO NCs exhibited two distinct sets of diffraction peaks, ZnO wurtzite structure, and ZrO2 phases (monoclinic + tetragonal). The SEM and TEM data show that ZrO2-doped ZnO particles were uniformly distributed on rGO sheets with the excellent quality of lattice fringes without alterations. PL spectra intensity and particle size of ZnO decreased after ZrO2-doping and rGO addition. DLS data demonstrated that green prepared samples show excellent colloidal stability in aqueous suspension. Biological results showed that ZnO/ZrO2/rGO NCs display around 3.5-fold higher anticancer efficacy in human lung cancer (A549) and breast cancer (MCF7) cells than ZnO NPs. A mechanistic approach suggested that the anticancer response of ZnO/ZrO2/rGO NCs was mediated via oxidative stress evident by the induction of the intracellular reactive oxygen species level and the reduction of the glutathione level. Moreover, green prepared nanostructures display good cytocompatibility in normal cell lines; human lung fibroblasts (IMR90) and breast epithelial (MCF10A) cells. However, the cytocompatibility of ZnO/ZrO2/rGO NCs in normal cells was better than those of pure ZnO NPs and ZnO/ZrO2 NCs. Augmented anticancer potential and improved cytocompatibility of ZnO/ZrO2/rGO NCs was due to ginger extract mediated beneficial synergism between ZnO, ZrO2, and rGO. This novel investigation emphasizes the significance of medicinal herb mediated ZnO-based NCs synthesis for biomedical research.

Impact of Thermal Processing on the Selected Biological Activities of Ginger Rhizome-A Review.

Ginger (Zingiber officinale Rosc.) is a spice, medicinal and cosmetic plant that has been known for centuries. It can be used in dried, fresh, marinated or candied form, and is also an essential ingredient in well-known curry blends. Ginger rhizomes are often freeze-dried as the first step in the preparation of the raw material. Many studies have proved that the composition and biological activity of ginger changes due to thermal processing. Therefore, the aim of the review was to summarize the scientific results on the impact of traditional and unconventional methods of the heat treatment of ginger rhizomes and their influence on the antioxidant and other selected biological activities of the plant. The review of the available scientific data is inconclusive, and it is hard to state unequivocally whether the thermal treatment of the raw material increases or decreases biological activity. Based on the presented literature review, it can be concluded that traditional cooking and microwave processing in general decrease the antioxidant activity of the ginger rhizome, whereas frying, autoclaving, blanching or traditional drying in the sun mostly lead to a significant increase in ginger activity. Interesting data were presented in the works describing the freeze-drying process during which the antioxidant potential of ginger increased.

Biochemical studies on the effect of some plants on the protection of the liver in experimental animals

Our topic in this research is related to protecting the liver from damage that can be caused by the presence of oxidized substances, which may cause liver damage, which reduces its efficiency as we looked for natural substances that are may have a positive effects on the liver and most internal organs without causing a bad side effects of organism. The target of this study is to evaluate the impact of ginger extracts on the protection of the liver affected by hydrogen peroxide in experiential rats, depending on the content of these extracts from total phenolic compounds and flavonoids. The experiment is based on two main points: (A) determine the chemical composition of ginger rhizomes; (B) evaluate the effect of ethanol and acetone extracts of ginger rhizomes against hydrogen peroxide (0.5%). Our results showed that, ginger rhizomes contained: 21.2% protein, 0.83% ash, 0.58% fiber, 6.98% fat, 58.9% total carbohydrates and 550mg/100g total phenolics. HPLC analysis for the ethanolic extract of ginger rhizome showed that its contain 17 phenolic compounds from which gingerols was the main one (8.77%) followed by zingerone (6.39%), while shogaols, vanillin, taxifolin, ferulic acid and cinnamic acid were in a moderate amount (4.82%, 3.7%, 3.4%, 3.08% and 2.0%), respectively. While, acetone extract of ginger rhizome contain 16 phenolic compounds, the main one is gingerols (9.6%), followed by zingeroene (7.0%), kaempferol (5.52%), shogaols (5.46%), vanillin (4.63%), taxifolin (4.53%), gallic acid(4.45%), ferulic acid (4.2%), cinnamic acid (2.63%) and syringic acid (1.96%).

Production of natural mouthwash: A sustainable processing path

In this study, extracts obtained from ginger rhizomes (Zingiber officinale) and chewing sponge-"Sawere" (Acacia kamerunensis) by cold maceration were used in the production of mouthwash solutions at the following concentrations: 10 ​mg/mL, 20 ​mg/mL, 50 ​mg/mL, and 75 ​mg/mL for ginger extract and 10 ​mg/mL only for "Sawere" extract. The solutions were tested for antimicrobial activity among seven candidates on three consecutive days. Results indicated that ginger mouthwash solution of 75 ​mg/mL concentration had the highest antimicrobial activity of 83.3 ​± ​2.5%, swiftly followed by ginger mouthwash solution of concentrations 50 ​mg/mL, 20 ​mg/mL and 10 ​mg/mL at 75.0 ​± ​2.5%, 47.9 ​± ​1.7% and 39.2 ​± ​2.0% respectively. This appeared to indicate that concentration and percentage inhibition in the ginger extract has a linear relationship. The 10 ​mg/mL concentration of Sawere extract solution exhibited very minimal antimicrobial activity at 0.2 ​± ​7.5%. GC-MS and FTIR analysis showed the presence of antimicrobial and anti-inflammatory compounds such as gingerol, neric acid, and squalene as well as other compounds such as 7- epi-cis-sesquiabinene present in both extracts. Gingerol was observed to demonstrate the highest peak in the ginger extract at a retention time of 17.484 whereas squalene exhibited the highest peak in sawere extract at a retention time of 17.811 in the GC-MS analysis. The FTIR analysis identified some functional groups in both the ginger and the sawere extracts including phenolics, alcohols, carboxylic acids, and alkane functional groups. This research successfully demonstrated the possibility of using ginger extracts and sawere extracts as safer active ingredient alternatives in the making of mouthwash.

Oral Administration Evaluation of the Hydro-Ethanolic Extract of Ginger (Rhizome of Zingiber officinale) against Postoperative-Induced Peritoneal Adhesion: Investigating the Role of Anti-Inflammatory and Antioxidative Effects.

Peritoneal adhesions (PAs) occur and develop after abdominal surgery. Abdominal adhesions are common and often develop after abdominal surgery. Currently, there are no effective targeted pharmacotherapies for treating adhesive disease. In this regard, ginger is wildly used in traditional medicine because of its anti-inflammatory and antioxidant effects and has been investigated for peritoneal adhesion treatment. This study analyzed ginger ethanolic extraction via HPLC to have a 6-gingerol concentration. Four groups induced peritoneal adhesion to evaluate ginger's effects on peritoneal adhesion. Then, ginger extract (50, 150, and 450 mg/kg) was administered by gavage in various groups of male Wistar rats (220 ± 20 g, 6-8 weeks). After scarifying the animals for biological assessment, macroscopic and microscopic parameters were determined via scoring systems and immunoassays in the peritoneal lavage fluid. Next, the adhesion scores and interleukin IL-6, IL-10, tumor necrosis factor-(TNF-) α, transforming growth factor-(TGF-) β1, vascular endothelial growth factor (VEGF), and malondialdehyde (MDA) were elevated in the control group. The results showed that ginger extract (450 mg/kg) notably decreased inflammatory (IL-6 and TNF-α), fibrosis (TGF-β1), anti-inflammatory cytokine (IL-10), angiogenesis (VEGF), and oxidative (MDA) factors, while increased antioxidant factor glutathione (GSH), compared to the control group. These findings suggest that a hydro-alcoholic extract of ginger is a potentially novel therapeutic strategy for inhibiting adhesion formation. Also, it might be considered a beneficial anti-inflammatory or antifibrosis herbal medicine in clinical trials. However, further clinical studies are required to approve the effectiveness of ginger.

Effect of ginger extract on sensory quality of spent Japanese quail meat tandoori

Spent Japanese quail (SJQ) meat was tenderized with ginger extract and utilized in the preparation of tandoori. The ginger extract level for tenderization of SJQ meat was optimized by physico-chemical and sensory analyses. The SJQ meat was treated with two levels of ginger extract and used for tandoori preparation along with two controls (broiler quail meat and spent quail meat). Japanese quail tandoori was prepared as four treatments namely CYB (Control young broiler), CSA (Control spent adult), G20 (Spent adult - ginger treatment 20%) and G40 (Spent adult - ginger treatment 40%). The aqueous ginger extract was prepared from fresh ginger rhizome (Zingiber officinale Roscoe). The SJQ was marinated in ginger extract marinade, tumbled, and placed in the chiller (4±1⁰C) for 24 hours and utilized for tandoori preparation. The cooked tandoori of all the treatments were analysed for the physico-chemical and sensory parameters. With ginger extract marination, the pH of cooked tandoori was not affected and the product yield was improved. In the organoleptic evaluation, the appearance score increased in the treatment with 20% ginger extract. The flavour score was significantly (p<0.05) higher in CYB and G20. The SJQ was significantly (p<0.05) tenderized by treatment with 20% and 40% ginger extract. CYB and G20 had significantly (p<0.01) higher scores for overall acceptability scores. It is concluded that 20% ginger extract level could effectively be used to tenderize the SJQ meat for the preparation of tandoori without affecting the physico-chemical and sensory properties.

The Impact of Different Drying Temperatures on Black Ginger Slices in Relation to Different Applications of Growing Media

Black ginger (Kaempferia parviflora Wall. Ex. Baker) or “halia hitam” in Malay has been traditionally used as health-promoting herbs in relieving body pains, allergies, gastrointestinal disorders, and fungal infections. Recently, black ginger has increased attention from many researchers to identify its medicinal value to treat diseases. In line with that, the objective of the study is to determine the impact of drying temperatures of black ginger rhizomes slices on the different applications of growing media. The experiment was arranged in a complete randomized design with two factors viz. i) different growing media [cocopeat, cocopeat+rice husk biochar, cocopeat+palm kernel shell biochar, cocopeat+sugarcane bagasse biochar, and cocopeat+coconut shell biochar] and ii) two different drying temperature (50 °C & 75 °C) with three replications. The postharvest parameters were total phenolic compound (TPC), total antioxidant (TA), water activity (Aw), and mineral nutrients content. In conclusion, rhizomes planted in Cocopeat+600g biochar substrates such as sugarcane bagasse, rice husk, palm kernel shell, and coconut shell could be suggested as effective growing media for black ginger cultivation under fertigation system and continued with 75 °C drying temperatures without adversely affecting the postharvest quality of black ginger.
