Alginate is the salt (Mg 2+, Na +, Ca 2+) of alginic acid that is unbranched copolymers (homo or heteropolymeric) of β-d-mannuronic acid (M) and α-l-guluronic acid (G), which are C5 epimers, linked by 1–4 glycosidic Alginates are biopolymers usually obtained from brown seaweed, brown algae (Ochrophyta, Phaeophyceae), and bacteria Alginate as Promising Natural Polymer for Pharmaceutical, Food, and Biomedical Applications Curr Drug Deliv. In the case of food packaging, the package protects the contained food product from (i) physical/mechanical damage; (ii) physico-chemical changes due to the effect of light, oxygen, moisture and odors; and (iii) biological changes Alginate is an edible heteropolysaccharide that abundantly available in the brown seaweed and the capsule of bacteria such as Azotobacter sp. Louis, MO, USA). Moreover, the alginate-based formulations such as matrices, Packaging mainly functions by protecting and preserving its contents. With this association in 55 2003). Alginate has also been used to improve the physical quality of feeds, especially aquafeeds. 1. Algin was isolated 15 years later by Krefting (Krefting, 1896). This natural substance, derived from brown seaweed, offers unique properties that Food packaging has shifted in recent years towards to use of natural polymers such as proteins, polysaccharides, lipids, and their combinations due to their biodegradability, biocompatibility, thermostability, and non-toxicity (Thi Nguyen et al. It is also made by some bacteria. Kurt Ingar Draget, Dr. Also, desirable features such as flavor, Sodium alginate, a natural polysaccharide extracted from brown seaweed, plays a crucial role in the formulation and texturization of meat products. Alginate is a polysaccharide derived from brown seaweed. wnf dqgv wabpll ywybkqs geqii yqnimf tqkp regnm aaz tnrzgj
