  • mechanism research on the pyrolysis of Seaweed Polysaccharides by py gc ms and subsequent density functional theory studies
    Journal of Analytical and Applied Pyrolysis, 2017
    Co-Authors: Shuang Wang, Zhen Xia, Qian Wang
    Abstract:

    Abstract In order to understand the pyrolysis mechanism of Seaweed Polysaccharide, the sulfated Polysaccharide was selected as the model compound in pyrolysis process and was theoretically investigated by employing density functional theory method B3LYP with the 6-31G+ (d, p) basis set. The pyrolysis gas chromatography mass spectrometry (Py-GC/MS) results indicate that the main products comprised furan and its derivatives, and the peak area percentage is 56%, among which the 5-methyl furfural (P6) is a major product that takes up more than 39.97%. Seven potential pathways were proposed to interpret the pyrolysis mechanism. The standard kinetic and thermodynamic parameters for all reaction pathways were obtained by DFT calculations. Based on both theoretical calculations and related experimental facts, the predicted main products are CO, CO2, SO3, furfural (P6) and 5- methyl furfural (P10), which are in good accordance with related experimental results. The proposed mechanism of reaction pathways for sulfated Polysaccharide pyrolysis provides insight into the pyrolysis behavior of Seaweed Polysaccharide.

  • co pyrolysis mechanism of Seaweed Polysaccharides and cellulose based on macroscopic experiments and molecular simulations
    Bioresource Technology, 2017
    Co-Authors: Shuang Wang, Qian Wang, Zhen Xia, Benjamin Bernard Uzoejinwa, Bin Cao
    Abstract:

    Co-pyrolysis conversion of Seaweed (Enteromorpha clathrat and Sargassum fusiforme) Polysaccharides and cellulose has been investigated. From the Py-GC/MS results, Enteromorpha clathrata (EN) Polysaccharides pyrolysis mainly forms furans; while the products of Sargassum fusiforme (SA) Polysaccharides pyrolysis are mainly acid esters. The formation mechanisms of H2O, CO2, and SO2 during the pyrolysis of Seaweed Polysaccharides were analyzed using the thermogravimetric-mass spectrometry. Meanwhile the pyrolysis of Seaweed Polysaccharide based on the Amber and the ReaxFF force fields, has also been proposed and simulated respectively. The simulation results coincided with the experimental results. During the fast pyrolysis, strong synergistic effects among cellulose and Seaweed Polysaccharide molecules have been simulated. By comparing the experimental and simulation value, it has been found that co-pyrolysis could increase the number of molecular fragments, increase the pyrolysis conversion rate, and increase gas production rate at the middle temperature range.

  • carrageenan a natural Seaweed Polysaccharide and its applications
    Carbohydrate Polymers, 2014
    Co-Authors: Vipul D Prajapati, Pankaj M Maheriya, Girish K Jani, Himanshu K Solanki
    Abstract:

    Polysaccharides have been gaining interesting and valuable applications in the food and pharmaceutical fields. As they are derived from the natural source, they are easily available, non-toxic, cheap, biodegradable and biocompatible. Carrageenan is one among them, which fulfills the criteria of Polysaccharide; it is a natural carbohydrate (Polysaccharide) obtained from edible red Seaweeds. The name Carrageenan is derived from the Chondrus crispus species of Seaweed (Rhodophyceace) known as Carrageen Moss or Irish Moss, and Carraigin. A demand based on its application has been widely increasing in food and pharmaceutical sectors. Carrageenan has gained wide applications in experimental medicine, pharmaceutical formulations, cosmetics, and food industries. Through keen references of the reported literature on carrageenan, in this review, we have described about carrageenan, its properties, extraction and refining, and its food and pharmaceutical applications.

  • Seaweed Polysaccharide in Food Contact Materials (Active Packaging, Intelligent Packaging, Edible Films, and Coatings)
    Dublin Institute of Technology, 2021
    Co-Authors: Perera Kalpani, Sharma Shubham, Pradhan Dileswar, Jaiswal Amit, Jaiswal Swarna
    Abstract:

    Food contact materials (FCMs) are materials that come in contact with food products such as food packaging which play a significant role in food quality and safety. Plastic, which is a major food packaging material, harms the ecosystem, wildlife, and the environment. As a result, numerous researches have been in progress on alternative polymers, which have similar properties as plastic but are also environmentally friendly (biodegradable). In recent years, the utilization of Seaweed Polysaccharides has piqued interest due to their biodegradability, non-toxicity, antioxidant capabilities, and excellent film formation ability. However, it has a number of drawbacks such as low tensile strength, water solubility, and moderate antibacterial characteristics, among others. The addition of other biopolymers, nanoparticles, or natural active agents improves these features. In this review article, we have summarized the current state of Seaweed Polysaccharide research in active packaging, intelligent packaging, edible films, and coatings. It also highlights the physical, thermal, antioxidant, and other properties of these materials. Finally, the article discusses the relevant legislation as well as the field’s future prospects. Research shows that Seaweeds Polysaccharide looks promising as a sustainable food contact material, but there is always a potential for development to make it market feasible
