Unlocking Nature's Potential: A Comparative Study of Bioactive Compounds Extracted from Tropical Microalgae. Mol Biotechnol 2024:10.1007/s12033-024-01080-2. [PMID: 38300455 DOI: 10.1007/s12033-024-01080-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2023] [Accepted: 01/12/2024] [Indexed: 02/02/2024]
Abstract
To promote the use of marine microalgae for nutraceuticals, we aimed to characterize extracts of Nannochloropsis oculata, Porphyridium cruentum, and Skeletonema costatum, all of which harbor numerous bioactive substances. Chlorophylls and carotenoids were identified as the primary pigments in N. oculata and S. costatum extracts. Furthermore, the total phenolic and total flavonoid contents in the three microalgae ranged 20.32-21.96 mg GAE/g and 0.3-2.1 mg QE/g, respectively. Notably, the extract of N. oculata exhibited the most significant radical scavenging activity in both 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) assays, with flavonoids and pigments identified as the main contributors to antioxidant activities. Our results revealed variations in metabolite profiles among the microalgal extracts: N. oculata extract (43 types), P. cruentum (13 types), and S. costatum (21 types). Hexadecanamide emerged as the major metabolite detected in all microalgae. Collectively, the results of the present study may open new avenues of microalgae for various applications.

Abstract
Beverage mixtures based on pineapple (Ananas comosus) and turmeric (Curcuma longa) juice as a ready-to-drink product were developed, and their physicochemical, nutritional, and sensory properties were evaluated. Four different concentrations of turmeric juice (5%, 10%, 15%, and 20% (v/v)) were added to pineapple juice to make turmeric-fortified pineapple (TFP) juice samples. Pineapple juice without turmeric was the control. The L*, a*, b*, titratable acidity (TA), total antioxidant capacity, and %DPPH scavenging values, as well as the concentrations of the phenolic compounds curcumin and demethoxycurcumin, were significantly increased with increasing turmeric concentration. Thirty volatile compounds were detected in the mixed juice samples with turmeric. Most of the turmeric-specific compounds, including monoterpenes, sesquiterpenes and turmerones, were detected in the TFP juice samples. While the antioxidant activity of the juice samples increased with increasing turmeric concentration, the pineapple juice fortified with 10% turmeric (10%T) had the best overall quality as determined by panelists. Greater concentrations of turmeric were associated with decreased palatability due to reduced mouthfeel and sweetness and increased aftertaste and sourness. These results suggest that the 10%T juice could be developed into a commercial functional beverage with increased overall flavor and nutritional quality.
