This algin derivative successfully stabilizes other acidic food emulsions, including bakery flavor and beverage emulsions ( 4S), These normally range in pH from 3 to 4 and contain from 10 to 30% flavor oils. 

Alginate Derivatives and Combinations with Other Polymers... 

In the particular case of polysaccharides, this reaction has been used for the modification of several types of biopolymers with different applications [28, 29]. As an example, a monoaldehyde derivative of P CD (2) was prepared from the hydrolysis of product 1 and then grafted, by a reductive amination-type reaction, onto an alginate derivative selectively modified with adipic dihydrazide (alg-ADH) (Scheme 7.5). The new polymeric materials obtained, alg-ADH intermediate and jS-CD-grafted alginate were fully characterized in terms of chemical integrity and purity by high-resolution NMR spectroscopy [30]. 

Microsphere beads were prepared with alginate-derived polymeric surfactants in aqueous solution of sodium and calcium chloride [33]. Ibuprofen, a hydrophobic drug, was loaded on the modified alginate beads and the in vitro control release was studied. It was found that drug loading level was higher than those obtained for unmodified alginated with a well controlled release rate [33].
