Sensory Profiles

The addition of Spirulina platensis in chocolate bar was reported to be able to increase the carotenoid content. Unfortunately, the fortified dry biomass generated fishy odor. In recent years, we succeeded to extract carotenoid from S. platensis, which was then encapsulated using a mixture of gum arabic and WPC by nanoemulsion technique. It helped reduce the fishy odor and concentrate carotenoid content in the nanocapsules. This study aimed to determine the effect of S. platensis’s carotenoid nanocapsules on the flavor profiles of dark and milk chocolate. The S. platensis’s carotenoid nanocapsules were added at a dose of 0.37% (w/w). Flavor profiles were detected using Gas Chromatography-Mass Spectrometry. A total of 79 aroma active were detected. The dark chocolate had a specific aroma of strong acidic chocolate, enriched with creamy and sweet. Meanwhile, the milk chocolate was dominated by creamy, cheesy, and sweet. The fortified chocolate had lower concentration of acids and aldehydes but had higher pyrazines and alcohols. Volatile compound that responsible for the fishy odor in Spirulina platensis was not detected in fortified chocolate. In conclusion, the fortification increased the intensity of sweet and chocolate flavor, decreased the bitter and sour flavor, and did not generate any unpleasant odor.

Silver and gold nanoparticles are promising tools for medical and industrial applications; therefore, their ecotoxicity should be carefully examined. There are many publications that discuss their effects at high concentrations on various organisms, while the effects of low doses have not been sufficiently investigated. In this paper, the effects of low concentrations of silver (12 nm) and gold (4.7 nm) nanoparticles coated with polyethylene glycol on Spirulina platensis biomass growth, biochemical composition, and antioxidant activity were investigated. The spirulina cultivation medium was supplemented with nanoparticles in the concentration range of 0.025–0.5 µM. The given concentrations stimulated spirulina biomass, but the content of proteins, carbohydrates, and auxiliary pigments was insignificantly affected by the presence of nanoparticles in the cultivation medium. Gold nanoparticles at a concentration of 0.5 µM produced a pronounced effect on the lipid content. Transmission electron microscope images demonstrated that the nanoparticles penetrate inside the cells and cause ultrastructural changes. The nanoparticles were characterized using several well-known techniques. The results confirmed a negative effect of low concentrations of metal nanoparticles on spirulina. This effect could be indiscernible when studying the biomass viability, but determination of the ultrastructure of the cell and the biochemical composition of the biomass could reveal it.

Water supplemented with 10% or 20% (v/v) of Zarrouk medium was used to cultivate Spirulina platensis in closed and open bioreactors under controlled conditions (30 °C, 32.5 μmol m−2 s−1, 12 h light/dark photoperiod) and in a greenhouse (9.4 to 46 °C, up to 2800 μmol m−2 s−1, variable day length photoperiod) using different initial biomass concentrations (X0) in the extreme south of Brazil (32.05° S, 52.11° W). Under controlled conditions the maximum specific growth rate (μmax) was 0.102 d−1, the biomass doubling time (td) was 6.8 d, the maximum dry biomass concentration (Xmax) was 1.94 g LD1 and the maximum productivity (Pmax) was 0.059 g L−1 d−1, while the corresponding values in the greenhouse experiments were μmax = 0.322 d−1, td = 2.2 d, Xmax = 1.73 g L−1 and Pmax = 0.112 g L−1 d−1. Under controlled conditions the highest values for these parameters occurred when X0 = 0.15 g L−1, while in the greenhouse X0 = 0.4 g L−1 produced the highest values. These results show that the cultivation of S. platensis in greenhouses in the extreme south of Brazil is technically viable and that the S. platensis inoculum and the concentration of Zarrouk medium can be combined in such a way as to obtain growth and productivity parameters comparable, or superior, to those occurring in bioreactors under controlled conditions of temperature, illuminance and photoperiod.
