“…The bitterness of pea and potato protein was adjusted by compound coagulation ( Zeeb et al, 2018 ). Natural biopolymer aromatic plant essential oil (EO) can be used as an excellent antibacterial agent, and its derivative EO microcapsule also has a particular fresh-keeping effect on fruits and vegetables ( Guo et al, 2021 ). Edible packaging produced by processing fruit waste can prolong the shelf life of food and maintain its nutrition ( Yadav et al, 2021 ).…”

Since the 21st century, natural biopolymers have played an indispensable role in long-term global development strategies, and their research has shown a positive growth trend. However, these substantive scientific results are not conducive to our quick grasp of hotspots and insight into future directions and to understanding which local changes have occurred and which trend areas deserve more attention. Therefore, this study provides a new data-driven bibliometric analysis strategy and framework for mining the core content of massive bibliographic data, based on mathematical models VOS Viewer and CiteSpace software, aiming to understand the research prospects and opportunities of natural biopolymers. The United States is reported to be the most important contributor to research in this field, with numerous publications and active institutions; polymer science is the most popular subject category, but the further emphasis should be placed on interdisciplinary teamwork; mainstream research in this field is divided into five clusters of knowledge structures; since the explosion in the number of articles in 2018, researchers are mainly engaged in three fields: “medical field,” “biochemistry field,” and “food science fields.” Through an in-depth analysis of natural biopolymer research, this article provides a better understanding of trends emerging in the field over the past 22 years and can also serve as a reference for future research.

“…For the preservation of fruits and vegetables, encapsulation methods have been extensively researched. Protein/polysaccharides were usually used as wall materials of EO microcapsules, such as β-cyclodextrin, pectin, chitosan, starch–gellan, alginate, sodium alginate, gelatin, and carboxymethyl cellulose ( 299 ). In a recent study, lemongrass EO-containing poly(lactic acid) nanocapsules were made to achieve long-term thermal stability of the EO.…”

Biocontrol Potential of Essential Oils in Organic Horticulture Systems: From Farm to Fork

et al. 2022

In recent decades, increasing attention has been paid to food safety and organic horticulture. Thus, people are looking for natural products to manage plant diseases, pests, and weeds. Essential oils (EOs) or EO-based products are potentially promising candidates for biocontrol agents due to their safe, bioactive, biodegradable, ecologically, and economically viable properties. Born of necessity or commercial interest to satisfy market demand for natural products, this emerging technology is highly anticipated, but its application has been limited without the benefit of a thorough analysis of the scientific evidence on efficacy, scope, and mechanism of action. This review covers the uses of EOs as broad-spectrum biocontrol agents in both preharvest and postharvest systems. The known functions of EOs in suppressing fungi, bacteria, viruses, pests, and weeds are briefly summarized. Related results and possible modes of action from recent research are listed. The weaknesses of applying EOs are also discussed, such as high volatility and low stability, low water solubility, strong influence on organoleptic properties, and phytotoxic effects. Therefore, EO formulations and methods of incorporation to enhance the strengths and compensate for the shortages are outlined. This review also concludes with research directions needed to better understand and fully evaluate EOs and provides an outlook on the prospects for future applications of EOs in organic horticulture production.

“…Essential oils are aromatic lipid compounds, largely present in flowers, buds, seeds, leaves, twigs, bark, herbs, wood, fruits, and roots (Álvarez‐Martínez et al, 2021; Burt, 2004; Guo et al, 2021). Essential oils are classified into many groups, including terpenes, terpenoids, and phenylpropanoids based on their chemical structure (Álvarez‐Martínez et al, 2021; Hussain et al, 2021).…”

Food Processing Preservation

Aquatic food products, including fish and crustaceans, are some of the most consumed foods globally and are highly prone to microbial contamination. Such products have been preserved using conventional processing techniques such as freezing, cold storage, modified atmospheric packaging (MAP), and vacuum packaging. However, these techniques have been used since decades and are not cost‐effective. Therefore, alternative sustainable strategies need to be explored. One viable option is the application of biopolymer‐based films and coatings loaded with active antimicrobial agents (peptides and essential oil components) for the preservation of aquatic food products. Nisin is the most widely used peptide for the development of antimicrobial coatings, while eugenol, carvacrol, and cinnamaldehyde are among the most popular essential oil compounds. Findings reveal that both peptides and essential oils, when applied in combination within a coating system, demonstrate robust antimicrobial activity, delayed lipid oxidation, and retain the overall quality of the aquatic food system. Novelty impact statement Antimicrobial‐based coating systems have recently gained worldwide attention due to their ability to delay food contamination and maintain product quality throughout the storage period. This review provides a comprehensive description of peptide and essential oil‐loaded coating systems and their application in the shelf‐life extension of aquatic food products. In addition, the application of nanocomposite systems for the preservation of aquatic foods has been discussed.
