Special Issue Information

Dear Colleagues,

The role of antioxidants and bioactive compounds in the agri-food sector has gained significant attention due to their crucial role in enhancing the quality and functionality of agri-food products. The exploration of antioxidants and bioactive compounds from natural sources, along with the assessment of their bioactivity, is increasingly undertaken to help consumers maintain or improve their quality of life. Their incorporation into agri-food products not only improves nutritional value but also extends shelf life, enhances sensory properties, and offers potential therapeutic benefits.

This Special Issue aims to publish high-quality articles and reviews exploring the latest advancements, innovative applications, and potential benefits of antioxidants and bioactive compounds in the agri-food sector. For such aims, principal topics may include, but are not limited to, the following:

  • The development of functional agri-food products and nutraceuticals enriched with antioxidants and bioactive compounds, targeting specific health outcomes and dietary needs.
  • Investigating the effectiveness of naturally derived antioxidants in preserving agri-food quality, preventing spoilage, and extending the shelf life of agri-food products.
  • Bioavailability of bioactive compounds in agri-food products.
  • Strategies to enhance antioxidant stability: microencapsulation and nanoencapsulation.
  • Investigations into the mechanisms of action of antioxidants and bioactive compounds for protecting against oxidative stress.
  • Innovative methods for extracting these compounds from natural sources and optimizing their concentration and stability in agri-food products.
  • Exploring the sustainability aspects of utilizing natural antioxidants and bioactive compounds, focusing on their environmental benefits and contributions to sustainable agriculture practices.

Citric acid (CAC) is a ubiquitous, odorless, and non-toxic food additive. Soft rot, caused by the pathogen Rhizopus stolonifer, is a major postharvest disease affecting sweet potato (Ipomoea batatas (L.) Lam). The main theme of this study is to determine the CAC inhibitory mechanism against Rhizopus stolonifer, the causative agent of sweet potato soft rot. To ascertain the practical applicability of CAC, both in vitro and in vivo methodologies were employed. The aim of the in vitro experiments in this study was to delineate the effects of a 0.5% (w/v) CAC solution on the growth inhibition of Rhizopus stolonifer, encompassing mycelial morphology and colony expansion. In vivo experiments were carried out using “Xinxiang” sweet potato varieties and the application of a 0.5% (w/v) CAC solution as a pretreatment. Specifically, the tissue treated with 0.5% CAC maintained better appearance quality and texture characteristics; peroxidase, β-1,3-glucanase, chitinase, and phenylalanine ammonia-lyase activities were enhanced. Conversely, the same treatment resulted in a downregulation of polyphenol oxidase, catalase, ascorbate peroxidase, cellulase, and polygalactosidase activities. Moreover, CAC treatment was found to maintain elevated levels of total phenolics and flavonoids within the sweet potato tissues. In summary, the study demonstrates that 0.5% CAC fortifies the resistance of sweet potato to soft rot by activating defense-related enzymes, suppressing the activity of cell wall-degrading enzymes, and promoting the accumulation of antimicrobial compounds. These results advocate for the utilization of CAC as a postharvest treatment to mitigate the incidence of sweet potato soft rot. Full article
