“…Sodium alginate films loaded with 10%–40% Clitoria ternatea extract (CTE) were developed and characterised by Santos et al . (2022), and the authors observed similar results for pure alginate films, which presented a smooth surface, dense and continuous, indicating good dispersion of the alginate in the glycerol plasticizer.…”

“…3) showed that the surfaces of all samples did not present voids or cracks, being uniform and smooth, which indicated that the dispersion of alginate and glycerol was effective for the control film (CF ), with the same characteristics observed in the incorporation of AA in formulations F1, F2 and F3. Sodium alginate films loaded with 10%-40% Clitoria ternatea extract (CTE) were developed and characterised by Santos et al (2022), and the authors observed similar results for pure alginate films, which presented a smooth surface, dense and continuous, indicating good dispersion of the alginate in the glycerol plasticizer.…”

“…Similar results were observed by Santos et al . (2022) in the development of sodium alginate films with the addition of 10%–40% Clitoria ternatea extract. High solubility in water is an important point when choosing the polymers used in the production of ODFs.…”

SummaryOrally disintegrating films (ODFs) have been studied for their innovative way of delivering active compounds into the oral cavity. The study aimed to develop and evaluate ODFs using sodium alginate and different concentrations of vitamin C. Four formulations were evaluated for barrier, mechanical, thermal, microstructural properties, surface pH, disintegration time and concentration of vitamins. The ODFs produced showed high solubility, pH close to oral and disintegration time ranging from 24.66 s for the control formulation to 56.28 s for the 1% ascorbic acid formulation. The release of vitamin C occurred after 1 min of reaction for all formulations with the lowest concentration (0.25%) releasing a volume of 80.46 mg g−1. Thermal analyses demonstrated the presence of sodium alginate and vitamin C, and an interaction between them, confirmed by FTIR spectra. This interaction was interesting for ODFs since it can affect the properties and release of the active compound from the polymeric matrix. The results positively demonstrated that sodium alginate can be a promising polymer in the production of ODFs and for use in the delivery of vitamin C.

“…Recently, Santos et al [ 172 ] developed an active intelligent packaging based on sodium alginate films incorporated with 40% of Clitoria ternatea extract (CTE) to monitor the quality of milk, pork, and shrimp. The proposed packaging showed a colorimetric potential as CTE is a pH sensitive compound and it changes color at different pH.…”

The food production industry is a significant contributor to the generation of millions of tonnes of waste every day. With the increasing public concern about waste production, utilizing the waste generated from popular fruits and vegetables, which are rich in high-added-value compounds, has become a focal point. By efficiently utilizing food waste, such as waste from the fruit and vegetable industries, we can adopt a sustainable consumption and production pattern that aligns with the Sustainable Development Goals (SDGs). This paper provides an overview of the high-added-value compounds derived from fruit and vegetable waste and their sources. The inclusion of bioactive compounds with antioxidant, antimicrobial, and antibrowning properties can enhance the quality of materials due to the high phenolic content present in them. Waste materials such as peels, seeds, kernels, and pomace are also actively employed as adsorbents, natural colorants, indicators, and enzymes in the food industry. Therefore, this article compiles all consumer-applicable uses of fruit and vegetable waste into a single document.

“…Sodium alginate, mainly extracted from the cell walls and intercellular spaces of marine brown algae, is a linear chain polysaccharide that contains two structural units of 1–4 linked α-L-guluronic acid and β-D-mannuronic acid [ 14 , 15 ]. This natural polymer is characterized by film-forming properties, resistance to oxygen permeability, and biocompatibility, making it an excellent component for producing functional packaging materials and in the medical field [ 16 , 17 , 18 , 19 ]. Alginates are used as an emulsifier, stabilizer, thickening agent, and flavor adjuvant.…”

Physicochemical and Antibacterial Properties of Alginate Films Containing Tansy (Tanacetum vulgare L.) Essential Oil

et al. 2023

Tansy (Tanacetum vulgare) is a common plant used in folk medicine for digestive problems, fevers, and migraines; against parasites; and as an insect repellent. The active substances in essential oil are responsible for its antimicrobial and antioxidant activity. Thus, tansy essential oil (TO) was added to alginate films to fabricate materials with antioxidant and antibacterial properties for food packaging. Sodium alginate films with glycerol and TO were tested in terms of structure, mechanical, thermal, antioxidant, and antibacterial properties. The structure of the films was examined using SEM and an ATR-FTIR spectrophotometer. The addition of TO to the alginate film significantly changed the films’ microstructure, making them rougher and porous. A low-intensity band at 1739 cm−1, indicative of the presence of TO, appeared in all spectra of alginate films with TO. Moreover, the studies revealed that essential oil acted as a plasticizer, slightly reducing tensile strength from about 7 MPa to 5 MPa and increasing elongation at break from 52% to 56% for the sample with 2% TO. The alginate films enriched in TO exhibited antioxidant properties (280 μmol Trolox/100 g of the sample with 2% TO) and antibacterial activity against Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa.
