Abstract

Microalgal omega-3 fatty acids have gained considerable attention as sustainable alternatives to fish-derived lipids due to environmental constraints, contamination risks, and increasing demand for nutraceutical products. However, the rapid growth of this field has led to a fragmented body of literature, necessitating a systematic evaluation of research trends and thematic developments. This study aims to examine the evolution, collaboration patterns, and thematic structure of microalgal omega-3 research using a bibliometric approach. Bibliographic data were retrieved from the Scopus database for the period 2010–2025 using relevant keywords, yielding 1,050 publications after screening. The dataset was analyzed using Biblioshiny and VOSviewer to assess publication trends, country contributions, journal distribution, author networks, and keyword co-occurrence. The results demonstrate a marked increase in publication output, particularly after 2017, indicating growing interest in sustainable lipid sources and functional food applications. India, China, and the United States emerged as leading contributors, supported by strong international collaboration. Thematic analysis identified four principal clusters: microalgal biotechnology and lipid production, nutritional and pharmaceutical applications, metabolic and biosynthetic pathways, and food and feed utilization. Therefore, this study highlights the rapid expansion and multidisciplinary nature of microalgal omega-3 research while providing insights to support future scientific development and innovation.

Abstract

Rambutan (Nephelium lappaceum) peel contains various bioactive compounds, including phenolics, flavonoids, and ellagic acid, which function as antioxidants. Antioxidants are compounds needed to inhibit radical reactions and oxidation processes that trigger various diseases. This study aims to determine the potential of rambutan peel to become a herbal tea. The study began with the determination of total phenolic and flavonoid levels in aqueous extracts of rambutan peel, followed by antioxidant activity assessment using the DPPH and FRAP methods. As a comparison, tea from tea leaves (Camellia sinensis) and herbal teas from kelor (Moringa oleifera) leaves and senduduk (Melastoma malabathricum L) leaves were used. The results showed that the aqueous extract of rambutan peel had a total phenolic content of 344.07 mg GAE/g and a flavonoid content of 7.96 mg QE/g, higher than those of tea leaves, kelor leaves, and senduduk leaves. Antioxidant activity test using the DPPH method showed that rambutan peel aqueous extract is an active antioxidant with an IC₅₀ of 0.797 µg/mL, with antioxidant activity 5.45 times stronger than tea leaves, 10.33 times stronger than moringa leaves, and 4.32 times stronger than senduduk leaves. Antioxidant test using the FRAP method also showed that the antioxidant capacity of rambutan peel water extract is 29.66 mgTE/g, higher than those of tea leaves, kelor leaves, and senduduk leaves, with values of 19.84 mgTE/g, 6.12 mgTE/g, and 14.52 mgTE/g, respectively. These data indicate that rambutan peel has strong antioxidant activity and has the potential to be developed as a herbal tea.Keywords: Nephelium lappaceum peel, antioxidants, herbal tea, DPPH, FRAP
