However, some substances existing in these materials can be toxic. Alginates in packaging Cooking or warming breaded foods composicin a microwave oven composicionn a lack of crunchiness. Development of compositional heterogeneity in alginate degraded in homogeneous solution.

Danish Medical Bulletin 55 1 Therefore, repeated impression procedures might dsntal a certain degree of cytotoxicity to the patient depending on the material composition Braga et al.

Journal of Food Processing and Preservation 35 El objetivo de este estudio fue evaluar la citotoxicidad de los alginatos para aplicaciones dentales.

Chemical, physical and biological properies of alginates and their biomedical implications. Alginates compisicion were reinforced by introduction of hydrolysed chitosans which diffuse into the alginate fiber allowing to introduce antibacterial properties Ion binding on polyuronates-Alginate and pectin.

The gel-forming process for alginate fibers and the gelling behavior of various types of alginate fibers were described.

Alginate partially complexed with calcium such as forming a loose gel mixed with starch was proposed to get high water retention in paper coating.

Rio de Janeiro, Guanabara Koogan S.

Alginates applications Alginates in Foods Up to now, the main applications of alginates were based mainly on their gel-forming ability and used as food additives in jams, jellies Three control groups were also used in this study: Alginates differ from each other according to the components present in their formulation.

Alginate is undoubtedly one of the most accepted materials used in dentistry. Correlation between chemical and physical properties of alginate gel beads. Food Control 22 This gives rise to the unique gel blocking properties of alginate wound dressings. Alginic acid fibers or silver fibers may also be prepared dsl enhance anti-microbial properties, zinc fibers to generate immune-modulatory and anti-microbial effects. Blending yarns and textile of alginate calcium fibers give good hand feeling and strength.

In the present study, the cytotoxicity of dental alginates was assessed through cytotoxic tests performed with mouse fibroblast L cells, a method largely used in several works evaluating the cytotoxicity of materials for use in dentistry Alcaide et al.

In rel short review, our objective was to describe few new applications of a natural polysaccharide extracted from algae, the alginates.

Alginate is an impression material classified as an irreversible hydrocolloid that is easy to handle, allowing good detail reproducibility in addition to being cheap and comfortable for the patient Anusavice, Wet-spinning is the usual way to produce fibers which may be highly absorbent wound dressing materials; especially, mixed sodium and calcium fibers may be produced, calcium giving the wet integrity and sodium the large absorbency.

It is important to select low-cytotoxicity materials before acquiring new products.

New products are now proposed for microwave heating by using active packaging with susceptors. Conclusion From this short review, it seems clear that alginates are new industrial polysaccharides which may be used in many other applications than only food industry.

The material used in the positive control group was a non-ionic surfactant Tweena toxic agent to biological membranes Rege et al. A review was recently available which is devoted to processing of alginate fibers for their use as a wound management material For many applications, these copolymers may compete directly with alginates Carbohydrate Polymer 79 Alginate applications, alginate composition, alginate fibers, alginate properties, Ca-gelation. After contact with the medium, the cells were incubated for further 24 hours in which ?

Wound treatment with Sorban-an alginate fibre dressing. Alginates in textiles and medical textiles A review was recently available which is devoted to processing of alginate fibers for their use as a wound management material Abstract In this short review, our objective was to describe few new applications of a natural polysaccharide extracted from algae, the alginates.

The other alginates had intermediate results. Due to the process in aqueous and mild conditions, it is also easy to prepare fibers for enzyme immobilization or as support for bioactive molecules The materials were previously sterilized by exposing them to ultra-violet light Labconco, Kansas, Missouri, USA during 1 hour.

Calle Batalla del 5 de Mayo, esquina Fuerte de Loreto. The culture medium was replaced with fresh medium every 24 hours, and the supernatants were collected after 24, 48, 72, and hours 7 days for analysis of the toxicity to L cells. Biohybrid glycopolymer capable of ionotropic gelation. Nevertheless, it must be mentioned that MM and MG blocks also interact with calcium counterions.

The main qualities of fibers and dressings as wound care products include that they are bacteriostatic, anti-viral, fungistatic, non-toxic, high absorbent, non-allergic, breathable, haemostatic, biocompatible, and manipulatable to incorporate medications, with good mechanical properties Figure 3. Comparison of gels of different chemical composition. Relationship between the molecular structure of alginates and their gelation in acidic conditions.

Conversely, Samuel et al. Fourteen different alginates were assessed: Biomaterials 4 New generation of medical textiles are an important growing field, showing great expansion, in wound management products The influence of culture conditions on mycelial structure and cellulase production by Trichoderma reesei Rut C Because of unique properties as high surface area to volume ratio, nanoscale fiber diameter, porosity, light weight, nanofibres are used in wound care.

The samples were kept in contact with culture medium during this 2-minute period, and the supernatants were then put in contact with the cells.
