Fatty Acid Content and Profile in Ulva lactuca in Response to Exposure to Variable Growth Conditions in Indoor Photobioreactors

Life, Journal Year: 2025, Volume and Issue: 15(1), P. 57 - 57

Published: Jan. 6, 2025

Seaweed presents a sustainable alternative source of valuable fatty acids (FAs) involving omega-3 (n-3) and omega-6 (n-6). As such, there is great potential to reduce pressure on wild fish populations, helping combat overfishing its associated global impacts. This study explored the effect various environmental factors FA content profile Ulva lactuca using indoor photobioreactors. The taxonomic identity U. was confirmed through DNA sequencing 3 markers (rbcL, ITS, tufa). effects temperature (8, 20, 30 °C), seawater salinity (3.5, 3.0, 2.5, 2.0% w/v), nutrient type concentration (0 or 6.4 ppm, consisting 50% w/w N-NO3, N-NH4, 0-1 ppm P-PO4), irradiance (50, 100, 150 μmol photons m-2 s-1) were evaluated. assessed their influence lactuca's biomass production rate (BPR), dry weight (DW), ash (AC), composition after 7 21 days. results revealed that days, polyunsaturated (PUFA) decreased with increasing (i.e., 38.9% ± 0.7, 33.8% 0.4, 27.0% 6.6% 0.1 for 2.0, 3.5% w/v, respectively). n-3 days increased significantly under following conditions: 8 °C, 2.5% nitrogen without addition phosphorous, an irradiation 50 s-1, affording low n-6/n-3 proportion fits desirable level n6/n3 ratio (1-10) balanced nutritional diet.

Innovative Dietary Solutions for Vegans: Macroalgae Amino Acids for Differentiated Nutrition

Published: March 4, 2025

Veganism is gaining popularity due to its ethical, health, and environmental benefits. However, many vegans face challenges in obtaining a complete essential amino acid profile from plant sources, making diversified protein sources crucial for balanced nutrition. Macroalgae, nutrient-rich food traditionally consumed Asia, offers solution by providing both non-essential acids vital optimal health. This study analyzed the profiles of seven macroalgae species northwest coast Iberian Peninsula using HPLC with fluorescence detection. All samples contained acids, although tryptophan was mostly absent. Brown algae displayed higher aspartate glutamate levels, contributing "umami" flavor, while red exhibited histidine lysine concentrations. These findings highlight as valuable source vegan diets, offering comprehensive personalized nutrition plans.

Nutritional Quality, Safety and Environmental Benefits of Alternative Protein Sources—An Overview

Nutrients, Journal Year: 2025, Volume and Issue: 17(7), P. 1148 - 1148

Published: March 26, 2025

Protein is a fundamental macronutrient in the human diet. It supplies our organisms with essential amino acids, which are needed for growth and maintenance of cells tissues. Conventional protein sources, despite their complete acid profiles excellent digestibility, have proven negative impact on environment. Furthermore, production poses many ethical challenges. This review aims to present nutritional, more ethical, environmentally friendly alternatives that could serve as potential sources population. The available literature alternative has been analyzed. Based research conducted, various products identified described, including plant-based such soybeans, peas, faba beans, lupins, hemp seeds; aquatic algae, microalgae, water lentils; well insect-based microbial cell-cultured meat. Despite numerous advantages, lower environmental impact, higher standards production, beneficial nutritional profiles, not without limitations. These include bioavailability certain presence antinutritional compounds, technological challenges, issues related consumer acceptance. Nevertheless, proper dietary composition, optimization processes, further advancements, presented can constitute valuable sustainable growing global

Characterization and Gelling Potential of Macroalgae Extracts Obtained Through Eco-Friendly Technologies for Food-Grade Gelled Matrices

Gels, Journal Year: 2025, Volume and Issue: 11(4), P. 290 - 290

Published: April 15, 2025

The growing demand for sustainable and nutrient-rich food sources has positioned macroalgae as a promising alternative product development. This study investigates the extraction characterization of hydrocolloids from three red species (Chondrus crispus, Gracilaria gracilis, Gelidium corneum) using water bath (WB), ultrasound (US), hybrid ultrasound–water (USWB) treatments 45 60 min. physicochemical properties extracts, including rheological behavior, particle size distribution, antioxidant activity, texture, were assessed. results show that C. crispus produced firmest gels due to its high carrageenan content, with WB USWB yielding most stable gel structures. In contrast, G. gracilis corneum exhibited lower strength, consistent their agar composition. WB-treated samples demonstrated superior retention, while US treatment was more effective in preserving color stability. findings highlight viable conventional hydrocolloids, reinforcing potential natural gelling agents, thickeners, stabilizers pharmaceutical industries. provides comparative evaluation WB, US, methods, offering insights into optimizing hydrocolloid enhanced functionality sustainability.
