Bioactive Compounds Incorporation into the Production of Functional Biodegradable Films - A Review

Abstract

The bioactive compounds incorporation for the production of biodegradable food packagings comes as a viable and environmentally friendly substitute in order to improve the nutritional value as well as extend the shelf life of highly perishable food products. Moreover, the use of bioactive compounds has been directly associated with the promotion of health aspects; the ingestion of bioactive compounds is related with minimizing risks of some diseases such as hypertension, diabetes, and coronary heart diseases. Therefore, the present study carried out a review of the current scenario in the film's production with natural antioxidants addition. The prebiotics and probiotics compound addition in films properties produced were also discussed in this work. Additionally, the film biodegradation properties should also be taken into account for their right disposal in the environment. Some factors that can to affect the biodegradation process are the nature of the polymer, the interactions among the blend components, its crystallinity, and the environmental conditions (light, temperature, O 2 concentrations; and humidity). Therefore, the evaluation of relationships between structure and the polymers biodegradability is the extreme importance.

Active properties of edible marine polysaccharide-based coatings containing Larrea nitida polyphenols enriched extract

“…In fact, several works have been carried out in the last decades dealing with active biopolymer matrices containing essential oils and/or natural extracts (Ganiari, Choulitoudi, & Oreopoulou, 2017;Moghimi, Aliahmadi, & Rafati, 2017). Polyphenolic-enriched plant extracts represent an interesting ingredient for the development of edible coatings, mainly due to their natural origin and phytochemical properties, which allows obtaining active materials with the aim of extending the shelf life and the value to the products (Luchese, Brum, Piovesana, Caetano, & Flôres, 2017;Mir, Dar, Wani & Shah, 2018).…”

Radiation modification and characterization of polyvinyl alcohol/starch/citric acid/glycerol bioblend film

“…Therefore, it could be observed from Figure 2(a) to (c) that the content of the CA should not exceed 1%, the Glyc content should not exceed 10 vol%, and the best irradiation dose is 10 kGy to obtain bioblend film with lower swelling behavior that has good water resistance. 26…”

“…Therefore, it could be observed from Figure 2(a) to (c) that the content of the CA should not exceed 1%, the Glyc content should not exceed 10 vol%, and the best irradiation dose is 10 kGy to obtain bioblend film with lower swelling behavior that has good water resistance. 26 Finally, the selected radiation modified PVA/St bioblend film at a dose of 10 kGy did not show any sign of degradation within the studied swelling period up to 72 h. Moreover, after its end of life, the ordinary water in soils will facilitate biodegradation, which is an exciting attribute for environmental sustainability. 27,28 The tensile strength significantly modified and improved at an irradiation dose of 10 kGy accompanied with little elongation (%) deterioration.…”

Green Design of Novel Starch-Based Packaging Materials Sustaining Human and Environmental Health

“…The research in incorporating vitamins into starch-based films and coatings is just beginning. The incorporation of the vitamins which possess antioxidant effect may be done during the manufacturing process because they protect against the film's oxidation [137]. The most commonly used method for incorporating vitamins into starch film is the solvent casting method [131,132].…”
