“…This high-density structure was due to the formation of the so-called "egg box structure" of Ca 2+ with homopolyguluronic acid blocks in the alginate. [42][43][44] Altogether, results found in this work indicate that alginate, enriched in homopolymannuronic acid from Himantothallus grandifolius formed polyelectrolyte complex with low molecular weight chitosan S with potential application in the oral delivery of bioactive compounds.…”

Hydrogels are three‐dimensional polymeric materials with applications in various areas such as biomedicine, tissue engineering, pollutant capture systems, and so forth. However, its application is limited due to the reproducibility of its properties. Factors such as the composition of the constituents, the type of union between the polymer chains, and the crosslinking time play a crucial role in ensuring its reproducibility. In this study, the objective is to prepare a matrix with well‐defined properties that ensure controlled release processes. Treatment of Himantothallus grandifolius with Na2CO3 aqueous solution afforded in 18.9% yield alkaline extract. Hydrogels were prepared by ionic complexation of alginate from H. grandifolius, and polyguluronate enriched alginate from Desmarestia ligulata with chitosan stabilized by immersion in 0.1 M CaCl2 solution; better swelling ratio in water was found for hydrogels with low molecular weight chitosan (MW 125,000 g/mol) than those with medium molecular weight chitosan (MW450,000–500,000 g/mol). Liberation of the model drug metformin hydrochloride from alginates: chitosan complexes (3:1) at pH 1.5 was especially low for hydrogel from H. grandifolius during the first 2 h; 70% of metformin was released at pH 6.5 after 24 h. This polyelectrolyte complex constitutes a good material for potential application in biomedicine considering its cationic and anionic characteristics.

“…The quantification is expected to be lower, around 7% of the value observed in the extract. The encapsulation efficiency was 45%, equation [ 7 ]. In the encapsulation of pomegranate extract using ionic gelation by dripping and with pectin as wall material, EE values of phenolic compounds between 41.2 and 43.4% were found [ 9 ].…”

“…The advantages in the formation, processing and versatility of the operation mode are avoiding the use of extreme temperatures that can affect the stability of the core or the wall material. In addition, pre-treatments are not required: the ionic gelation method is considered a competitive alternative to encapsulate and protect SO, compared to encapsulation techniques such as spray drying, freeze drying, fluidized bed drying, and coacervation [ 7 ]. Among the core materials often used in ionic gelation is sodium alginate which, with the addition of calcium salts, will be converted into sodium alginate, a water-insoluble compound.…”
