Abstract
Marine algae, particularly Caulerpa lentillifera (C. lentillifera), have gained attention as potent sources of bioactive compounds with diverse health benefits. Despite its promising bioactivity, the influence of drying methods on its health-promoting properties remains underexplored. This study investigates the impact of different drying methods on the antioxidant, antidiabetic, and antiobesity activities of C. lentillifera. Fresh samples (GACL-FS) and those dried using air-fryer (GACL-AFD) and microwave (GACL-MD) methods were evaluated for carrageenan content, protein composition, and bioactive potentials. GACL-MD preserved the highest levels of protein, while fresh samples retained the highest carrageenan content. Antioxidant assays revealed superior performance in GACL-MD samples, showing significant DPPH and ABTS inhibition compared to Trolox standards. Similarly, antidiabetic assays demonstrated comparable α-glucosidase inhibition across all drying methods, suggesting robust retention of antidiabetic properties. Antiobesity activity, evaluated through lipase inhibition assays, highlighted GACL-MD's efficacy at lower concentrations, akin to Orlistat, while fresh and air-fryer dried samples showed varied results. In conclusion, C. lentillifera exhibits substantial potential as a functional food ingredient, with the drying method significantly influencing its bioactive profile. Microwave drying emerged as optimal for preserving antioxidant and antiobesity activities, emphasizing the need for tailored drying strategies to enhance nutritional benefits. Future research should focus on optimizing processing techniques and elucidating underlying mechanisms to fully harness C. lentillifera's health-promoting properties in functional food development and public health interventions.
期刊介绍:
Algal Research is an international phycology journal covering all areas of emerging technologies in algae biology, biomass production, cultivation, harvesting, extraction, bioproducts, biorefinery, engineering, and econometrics. Algae is defined to include cyanobacteria, microalgae, and protists and symbionts of interest in biotechnology. The journal publishes original research and reviews for the following scope: algal biology, including but not exclusive to: phylogeny, biodiversity, molecular traits, metabolic regulation, and genetic engineering, algal cultivation, e.g. phototrophic systems, heterotrophic systems, and mixotrophic systems, algal harvesting and extraction systems, biotechnology to convert algal biomass and components into biofuels and bioproducts, e.g., nutraceuticals, pharmaceuticals, animal feed, plastics, etc. algal products and their economic assessment
