“…Assis et al () reported that addition of the carotenoid lycopene reduced the passage of ultraviolet–visible light (UV–vis) through the cassava starch films. Stoll, Marli, Nachtigall, Rech, and Hickmann () found that the addition of bixin, beta‐carotene, and lycopene carotenoids significantly reduced the light transmittance of poly (lactic acid) films.…”

Plastic packaging derived from petroleum may have a negative impact on the environment when it is not properly recycled. Some studies present the use of biodegradable packages developed from natural polymers as a sustainable alternative; thus, the present work aimed to develop biodegradable sodium alginate films with antioxidant properties by the incorporation of carotenoid norbixin. Norbixin salts at the concentration of 0.01-0.05% were added to the sodium alginate films complexed with calcium ions. Carotenoid incorporation did not significantly impacted with the moisture content and the swelling capacity of the films. The thickness, water activity, and solubility were higher in the films with 0.05% addition of norbixin salts. The presence of the carotenoid improved the thermal stability of the films, as well as the water vapor barrier properties and lower ultraviolet-visible light transmission. However, the incorporation of 0.03% norbixin salts showed the best result for the analysis of antioxidant activity, with lower formation of oxidation products during sunflower oil storage and potential application for high fat foods. Practical ApplicationsResearchers aim to replace synthetic packaging by eco-friendly packaging. The use of alternative materials such as polysaccharides, proteins, and lipids has been studied for the production of packaging susceptible to degradation under environmental conditions. Thus, the present work developed sodium alginate films complexed with calcium and incorporated with norbixin salts able to decrease sunflower oil oxidation.

“…In previous studies of our group, bixin‐rich extracts were used as a coloring and antioxidant additive in cast PLA films. Bixin was shown to be stable in the PLA matrix after film obtention, endowing films with light barrier properties and protecting sunflower oil from oxidation reactions 15,16 . When introduced into poly(hydroxy butyrate) films, annatto extracts protected the polymer against thermal degradation and erosion caused by light 17 …”

Packaging materials are decisive to preserve the quality and nutritional value of food. Polylactide (PLA) is a biodegradable polymer with adequate mechanical properties for packaging applications, but its moderate oxygen barrier properties and high UV light transmission hamper its performance as packaging for oxygen‐ and light‐sensitive products. Bixin, a carotenoid with coloring and antioxidant character, was used to improve the light barrier of PLA films plasticized or not with acetyl tri‐butyl citrate (ATBC). The films were subjected to thermal treatment mimicking polymer processing temperatures. Despite more than 74 wt% of bixin degraded during heat treatment, films were still blocking up to 95% of UVA and 90% of UVB transmission. Plasticizing PLA with ATBC accelerated up to six times the bixin release into a food simulant, which allowed to reach relevant concentrations for food preservation. In conclusion, bixin is a promising natural antioxidant and UV‐shielding additive of biodegradable packaging.

“…On the other hand, it was acted as a hiding agent confirmed by SEM micrographs (Pagnan et al., 2018). In another study, Stoll, Rech, Flôres, Nachtigall, and de Oliveira Rios (2018) used carotenoids as colorants for polymeric materials (PVAs) to represent an environmentally friendly method for obtaining colored packaging. Their results showed that in the presence of carotenoids (100 µg/g), oxygen permeability of the films was reduced, a lubricant effect was observed, and the elasticity of the films increased up to 50%.…”

“…The most impacting factor on carotenoids color stability was light exposure due to the destruction of their structure; the most stable carotenoid at dark and light conditions was bixin. Finally it was reported that the colored PLA films were more suitable to protect oxidation‐sensitive products (Stoll et al., 2018).…”

The development of smart packaging and innovation in common food packaging technology will greatly help to meet market needs, including consumer preference for "safe" foods, high-quality products and mitigate the negative environmental impacts of food packaging. In addition, consumers' tendency to use natural ingredients such as pigments and biopolymers has provided the basis for their application in the food industry, including smart food packaging. Hence, smart packaging in addition to protecting food products against environmental damage can also reveal a sign (colorimetric, chemical, electric, etc.) in real time in response to any changes in the packaging conditions and food quality. This comprehensive review emphasizes on the gas/temperature-sensitive smart films based on natural colorants and their key applications in the food packaging systems. Technological considerations associated with the natural colorantresponsive films, smart packaging, biopolymers, and importance of natural colorants versus synthetic dyes are investigated. In practice, the most common designed colorimetric indicators for monitoring gas and temperature changes and application of relevant smart films in real food models have also been discussed. Gas and time-temperature indicators provide a rapid, reliable, and online assessment and a visual indication of the food product quality level, usually through a color change, which is directly related to gas and temperature conditions during distribution and storage of relevant food products. However, future studies need to consider main points such as cost, consumers' acceptance, and confidence, regulatory aspects (i.e., labeling) and multifunctionality of smart packaging to be commercially sustainable.
