Summary
This bibliometric analysis reveals a significant increase in antioxidant research, shifting focus from vitamins and minerals to plant-derived compounds. Key areas include biochemistry, food science, and medicine, with emerging contributions from Brazil, China, India, and South Korea.
Area of Science:
- * Multidisciplinary research spanning biochemistry/molecular biology, food science technology, and pharmacology/pharmacy.
- * Historical focus on polymer science has declined, with a resurgence in antioxidant-related publications since 1991.
Background:
- * Antioxidants from natural dietary sources offer potential health benefits.
- * Lack of comprehensive literature analysis on the scientific impact and citation trends of antioxidant research.
- * Growing body of scientific literature on antioxidants necessitates a bibliometric evaluation.
Purpose of the Study:
- * To identify and analyze antioxidant publications within the scientific literature.
- * To evaluate the scientific impact and citation trends of antioxidant research.
- * To map the evolution of research focus within the field of antioxidants.
Main Methods:
- * Bibliometric analysis of 299,602 manuscripts sourced from the Web of Science database.
- * Utilized VOSviewer software for analyzing full records and cited references.
- * Temporal analysis of citation patterns and publication trends.
Main Results:
- * Most publications originated after 1991, with significant contributions from the USA, Brazil, China, India, and South Korea.
- * Leading journals include Food Chemistry, Journal of Agricultural and Food Chemistry, Free Radical Biology and Medicine, and PLOS One.
- * Research highlights clinical conditions like Alzheimer's disease, cancer, and cardiovascular disease, and compounds such as flavonoids, vitamin C, vitamin E, and resveratrol.
Conclusions:
- * A notable shift in scientific interest from antioxidant vitamins and minerals towards antioxidant phytochemicals (plant secondary metabolites).
- * Emerging research hubs in South America and Asia indicate a global expansion of antioxidant studies.
- * Continued investigation into antioxidants is crucial for understanding their role in health and disease.

Chemistry is an empirical science. Scientists often pose questions to understand the chemistry in everyday life and seek answers to these questions. To achieve this, scientists follow a definitive series of steps that together make up the Scientific Method. This approach involves making observations, asking questions, building a hypothesis, conducting experiments, analyzing results, and forming a conclusion.

The scientific method is a detailed, empirical problem-solving process used by biologists and other scientists. This iterative approach involves formulating a question based on observation, developing a testable potential explanation for the observation (called a hypothesis), making and testing predictions based on the hypothesis, and using the findings to create new hypotheses and predictions.
Generally, predictions are tested using carefully-designed experiments. Based on the outcome of these...

Research is what makes the difference between facts and opinions. Facts are observable realities, and opinions are personal judgments, conclusions, or attitudes that may or may not be accurate. In the scientific community, facts can be established only using evidence collected through empirical research.

Social psychology is a scientific discipline dedicated to understanding how individuals think, feel, and behave in social contexts. Unlike common sense, which relies on anecdotal experiences and intuition, social psychology employs systematic research and empirical methods to ensure objectivity and reliability. This distinction is fundamental in distinguishing scientifically supported findings from mere speculation.Four fundamental scientific values guide a structured approach to research in...

The scientific method provides the foundation for any research. It is the most reliable and objective of all forms of gaining knowledge and guides in applying research-based evidence in practice and conducting future research.
When using research findings to change practice, one must understand the process used to guide a study. The scientific method is a systematic, step-by-step process that supports the data's validity, reliability, and generalizability. As a result, findings can be...
