Special Issue Information

Dear Colleagues,

In recent years, consumers' perceptions of synthetic preservatives have grown unfavorable. In response to this, research is being focused on the extraction, characterization, and application of natural additives with the aim of increasing the food shelf life. Plants, animals, and microorganisms are considered the natural active component reservoirs. In addition, food industry by-products are an attractive source of bioactive compounds, at low cost and high availability. Natural antimicrobial and antioxidant agents have shown high potential to inhibit the growth of foodborne microorganisms and minimize oxidative reactions; however, their effects in real-world applications have not been fully evaluated in food products. Considering active and smart packaging, many studies have demonstrated the application of the bioactive additives in the polymeric matrix, but few works have applied the developed package in food and evaluated its shelf life, thus requiring further studies to enable a commercial application. In this Special Issue, we invite researchers to submit original research or reviews articles on natural antimicrobial and antioxidant agents used in food packaging and preservation. Topics of interest include the development, characterization, and application of active or smart packaging in food systems or simulants.

Plastic pollution and the reduction in synthetic food additives are demands that emerge from consumers, leading to the development of biodegradable plastic materials. The use of essential oils—EOs—has been researched because it is a natural product with antioxidant properties. Due to its nature, EO is composed of volatile compounds that can be lost during extrusion. The aim of this work was to produce active biodegradable starch/PBAT films with the incorporation of neat Eucalyptus citriodora EO (0.5, 1.0, and 1.5%) or EO microencapsulated by spray drying (2.5, 5.0, and 7.5%), aiming at the protection of the EO. The produced films showed adequate mechanical properties (tensile strength ranged from 5.72 to 7.54 MPa and the elongation at break ranged from 319 to 563%). Testing in food simulants showed that the films retained antioxidant activity, being more suitable for use in fatty or non-acid foods, with the microencapsulation process offering protection to the EO during the process.

Oxidative stress occurs in the process of egg storage. Antioxidants as feed additives can enhance egg quality and extend the shelf life of eggs. Selenium-enriched Cardamine violifolia (SEC) has strongly antioxidant properties. The objective of this study was to assess the effects of dietary supplementation with SEC on egg quality and the yolk antioxidant capacity of eggs stored at 4 °C and 25 °C. Four hundred fifty 65-week-old, Roman hens that were similar in laying rate (90.79 ± 1.69%) and body weight (2.19 ± 0.23 kg) were divided into 5 groups. The birds were fed diets supplemented with 0 mg/kg selenium (Se) (CON), 0.3 mg/kg Se from sodium selenite (SS), 0.3 mg/kg Se from Se-enriched yeast (SEY), 0.3 mg/kg Se for selenium-enriched Cardamine violifolia (SEC) or 0.3 mg/kg Se from Se-enriched Cardamine violifolia and 0.3 mg/kg Se from Se-enriched yeast (SEC + SEY) for 8 weeks. The eggs were collected on the 8th week and were analyzed for egg quality and oxidative stability of yolk during storage at 4 °C or 25 °C for 0, 2, 4, or 6 weeks. Dietary SEC and SEC + SEY supplementation increased the Haugh unit (HU) and albumen foam stability in eggs stored at 4 °C and 25 °C (p < 0.05). SS and SEC supplementation increased the yolk index in eggs stored at 25 °C (p < 0.05). SEC or SEC + SEY slowed down an increase in albumen pH and gel firmness in eggs stored at 4 °C and 25 °C (p < 0.05). Moreover, SEC or SEC + SEY alleviated the increase in malonaldehyde (MDA), and the decrease in total antioxidant capacity (T-AOC) level and total superoxide dismutase (T-SOD) activity in yolks stored at 4 °C and 25 °C (p < 0.05). These results indicate that SEC mitigated egg quality loss and improved the antioxidant capacity of yolks during storage. SEC supplementation would be advantageous to extend the shelf life of eggs.

In samples of Artemisia campestris (AC), Artemisia herba-alba (AHA) and Salvia jordanii (SJ) essential oils, up to 200 distinct volatile compounds were identified. Using headspace solid-phase microextraction combined with gas chromatography–olfactometry–mass spectrometry (HS-SPME-GC-O-MS), different panelists detected 52 of these compounds. This study offers the most detailed analysis of bioactive compound profiles conducted so far. The most abundant compounds identified were curcumene, making up 12.96% of AC, and camphor, constituting 21.67% of AHA and 19.15% of SJ. The compounds with the highest odor activity value (OAV) were (E,Z)-2,4-nonadienal (geranium, pungent), 3-nonenal (cucumber) and 2-undecenal (sweet) in AC, AHA and SJ, respectively. AHA essential oil showed significant antioxidant activity (IC50 = 41.73 ± 4.14 mg/g) and hydroxyl radical generation (hydroxylation percentage = 29.62 ± 3.14), as assessed by the diphenylpicrylhydrazyl (DPPH) method. In terms of oxygen radical absorbance capacity (ORAC), the strongest antioxidant activity was obtained for SJ essential oil (antioxidant activity of the essential oils, AOX = 337.49 ± 9.87).
