Evaluation of the phytochemical and medicinal value of lemongrass (Cymbopogon citratus), by conversion into powders and extracts to develop a nutritional bakery product
2024-12-03
(Press-News.org) Background and objectives
Because of its extraordinary phytomedicinal potential and numerous potential health benefits, lemongrass (Cymbopogon citratus), a well-known medicinal and aromatic plant, is of paramount significance. It is typically used as a drug replacement.
Methods
The present study was comprised of drying lemongrass into powder and determining the proximate and mineral composition, and then developing ethanolic extracts of powder to determine total phenolic contents (TPC), total flavonoid contents (TFC), total carotenoids (TC), and DPPH free radical scavenging activity. Next, lemongrass powder (LGP) was replaced at 0, 2.5, 5, 7.5, and 10% levels to develop nutritional biscuits.
Results
The results revealed that lemongrass powder contained higher fiber (8.34 ± 0.04%) and ash (7.26 ± 0.06%) quantities, than wheat flour. Similarly, essential minerals Ca, Mg, K, Fe, and Zn contents in LGP were 36.80 ± 0.12, 64.89 ± 0.13, 54.65 ± 0.18, 12.68 ± 0.05, and 8.46 ± 0.07 mg/100 g dry weight, respectively, which were significantly higher than that calculated in wheat flour. Phytochemical analyses of lemongrass ethanolic extracts documented TPC as 240.46 ± 0.20 mg gallic acid equivalent/100 g, TFC as 98.45 ± 0.15 mg catechin equivalent/100 g, TC as 62.36 ± 0.12 mg/100 g, and DPPH activity as 60.18 ± 0.14 mg AAE/100 g, with such values being significantly higher than those in wheat flour.
Conclusion
Incorporation of LGP at different levels in wheat flour resulted in boosted phytochemical profiles of nutritional biscuits, but upon sensory evaluation of biscuits 2.5% level of LGP provided good scores for taste, flavor and overall acceptability, while for color and flavor 5% LGP was also found to be suitable with highest sensory scores.

A series of five papers, published today in The Lancet Oncology by a University of Pittsburgh-led international team, highlights critical public health challenges related to cancer control in the eight countries that form the South Asian Association for Regional Cooperation (SAARC) and the Rohingya refugee population in Bangladesh. The series underscores barriers contributing to significant disparities in cancer outcomes and identifies actionable solutions to address these challenges in one of the most comprehensive ...

White, male, billionaire entrepreneurs fuel stereotypes that compound the issues surrounding diversity in technology and computer science, according to a new study.
The identities of famous people contribute a lot to stereotypes in their respective domains. Prominent public figures can easily become influential to young people. But are these role models effective for creating a diverse community of computer science students? That, at this point in time, seems unlikely.
The study, carried out by the University of Reading and published today ([INSERT DATE]) in the Oxford Review of Education, ...

Newly discovered insect fossils are so small they can barely be seen by the human eye but have been preserved in an “extraordinary” way.
Published in the journal Palaeobiodiversity and Palaeoenvironments, a new study reveals rare whitefly insect fossils have been found in Miocene age crater lake sediments at Hindon Maar, near Dunedin.
Adult whiteflies are tiny insects about 3mm in size, smaller if they are immature.
The fossils found at Hindon Maar are about 1.5mm by 1.25mm and have been preserved in the position they lived and died, attached to the underside ...

A new study published today in JAMA reveals text message reminders for patients who delay refilling their medications didn’t help improve how regularly they refilled medications over a year.
The study enrolled over 9,000 patients in a randomized pragmatic clinical trial and included representation from a diverse population across subgroups, including females, Hispanic ethnicity and Spanish-speaking patients, all groups who can be traditionally underrepresented in clinical trials.
“There are a lot of studies that focus on using technology ...

School-based mental health support should be more accessible for migrant children, a new study says.
Schools are increasingly considered to be critical places for identifying and supporting mental health difficulties, but little is known about the barriers migrants face in accessing mental health support in schools.
Researchers found a lack of targeted school-based mental health interventions designed specifically for young migrants that cater to their unique strengths, resilience and needs.
The review of 38 studies shows that stigma around mental health and stressors associated with migration were among ...

Researchers from the University of Hawai‘i at Mānoa Department of Earth Sciences assessed an unprecedented 120 years of data from Kīlauea Volcano on Hawai‘i Island, uncovering, for the first time, century-spanning patterns of deformation and stress changes. They had a particular focus on the transformative 1975 magnitude 7.7 Kalapana earthquake, which also resulted in a 20-foot high tsunami. Their study was published recently in the Journal of Geophysical Research: Solid Earth.
“Deciphering Kīlauea's history deepens our understanding of volcanic and seismic hazards,” said lead author Lauren Ward ...

McGill University scientists have discovered that pregnancy may trigger a natural immunity to boost protection against severe flu infection.
Contrary to the common belief that pregnancy increases vulnerability to infections, researchers found that it strengthened an immune defense in mice, blocking the Influenza A virus from spreading to the lungs, where it can cause severe infection.
“Our results are surprising because of the current dogma, but it makes sense from an evolutionary perspective,” said co-lead author Dr. Maziar Divangahi, ...

A groundbreaking Rice University study sheds light on the extraordinary evolution of anglerfish, a group of deep-sea dwellers whose bizarre adaptations have captivated scientists and the public alike. The research, published in Nature Ecology & Evolution, uncovers how these enigmatic creatures defied the odds to diversify in the harsh, resource-poor environment of the bathypelagic zone — part of the open ocean that extends from 3,300 to 13,000 feet below the ocean’s surface.
Led by a team of biologists including Rice’s ...
