“…The higher occurrence of 8-heptadecene in the VAC samples appeared to be related to the damage caused by the compression of the UL during the packaging process. Numerous studies have reported the presence of heptadecane or heptadecene in "laver" seaweeds [106,110,111], including heptadecane in P. umbilicalis [112] and 8-heptadecene in Pyropia spp. [109,113].…”

Conventional conservation techniques such as drying, salting or freezing do not allow for preserving the original characteristics of seaweeds. The present work aims to study the impact of minimal processing, in particular “Modified Atmosphere Packaging” (MAP), on the physicochemical characteristics and food safety of two seaweed species, “laver” (Porphyra umbilicalis) and “sea-lettuce” (Ulva lactuca), stored at 6 °C for 15 days. Different parameters were evaluated using analytical methods, namely the composition of headspace gases, color, texture, microorganisms, and volatile organic compounds (VOCs). The main findings of this study were that the MAP treatment was able to inhibit the respiration rate of minimally processed seaweeds, also preserving their color and texture. There was a remarkable reduction in the microbial load for P. umbilicalis treated under modified and vacuum atmospheres, and U. lactuca exhibited relatively steady values with no notable differences between the treatments and the control. Therefore, during the 15-day study period, both seaweeds met the requirements for food safety. GC–TOF-MS allowed to conclude that both MAP and vacuum treatments were more efficient in maintaining the odor characteristics of U. lactuca compared to P. umbilicalis with no significant differences throughout the storage days. Metabolic responses to diverse sources of abiotic stress seemed to account for most of the changes observed.

“…23 There are many kinds of seaweeds, and to date, tens of thousands of different seaweeds have been identified. 24 Seaweeds generally reproduce asexually, which allows for fast propagation of the species. Moreover, it has been more than 70 years since seaweeds were shown to be among Earth's most productive organisms.…”

“…Seaweeds, mainly macroalgae that can be seen with the naked eye, are classified into three major groups: brown algae (Phaeophyceae), green algae (Chlorophyta), and red algae (Rhodophyta) . There are many kinds of seaweeds, and to date, tens of thousands of different seaweeds have been identified . Seaweeds generally reproduce asexually, which allows for fast propagation of the species.…”

Materials capable of separating and removing iodine vapor from nuclear fuel reprocessing off-gases are significant to our environment, especially for human health. Adsorption is an effective and widely used separation method. In this work, a novel biomass alginate-based composite [N 1111 ][Alg]@MF was fabricated by modifying biomass polymers from seaweeds and used for effective iodine capture. Starting materials such as [N 1111 ][Alg] @MF are accessible and low-cost. Benefiting from abundant functional groups in alginate and the high porosity provided by MF, the iodine adsorption capacity of [N 1111 ][Alg]@MF was as high as 5.82 g g −1 , and the adsorption equilibrium could reach within 9 h. The combined experimental characterization and theoretical density functional theory calculations clearly reveal the I 2 capture mechanism. The abundant hydroxyl and carboxyl functional groups in [Alg] − played an important role in the accumulation of iodine. In addition, the high physicochemical stability makes [N 1111 ][Alg]@MF exhibit very excellent I 2 adsorption recyclability, which highlights their great potential in practical applications. Given the worldwide abundance and renewability of seaweeds, [N 1111 ][Alg]@MF can easily be employed as low-cost, large-scale applied green adsorbents for effective iodine capture.

“…In addition to containing a wide range of biologically active substances, U. pinnatifida and L. japonica have a special marine aroma. Li et al (2023) found that some volatile compounds in seaweed have a significant impact on its flavor. These volatile compounds produce different odors, such as “seafood”, “licorice”, “spices”, “honey”, and “fruit”, which can affect consumer preference for seaweed food.…”
