This article reviews data on antimicrobial additives used in the food industry for preserving the quality of food products. The use of conventional antimicrobial additives, including artificial preservatives (benzoic and sorbic acids and their salts), causes a negative response among consumers. As a result, such products are gradually disappearing from the market. At the same time, antimicrobial additives of natural origin are gaining in popularity, increasingly attracting the attention of both Russian and foreign researchers. In this article, the main antimicrobial additives of animal, vegetable and microbial origin are considered. Antimicrobial additives of animal origin are represented by lysozyme and lactoperoxidase enzymes, lactoferrin and pleurocidin peptides, as well as by chitosan, a derivative of chitin. Plant substances that exhibit antimicrobial and antioxidant properties include herbs and spices, both in native and dried form, as well as separately extracted plant components, such as essential oils, phenolic compounds and organic acids. Substances of microbial origin, in particular bacteriocins, comprise another promising class of antimicrobial additives. These forms represent smaller polypeptide molecules synthesized on ribosomes, which exhibit antagonistic activity against closely related groups of bacteria. Bacteriocins, such as nisin, natamycin, pediocin, enterocin and plantaricin, may exhibit bactericidal properties, at the same time as having little therapeutic value and no negative effect on the human intestinal microflora. This makes them different from antibiotic preparations. The conducted review confirms the prospects of using the considered additives in the composition of both food products and active packaging systems.

“…Chitosan is the product of deacetylation of chitin and is a copolymer composed of β-(1 → 4)-2-acetamido- d -glucose and β-(1 → 4)-2-amino- d -glucose units. − When the degree of deacetylation (DD) of chitin reaches about 50%, it is known as chitosan. , Chitosan can be dissolved in aqueous acidic media, and the amino group at the C-2 is protonated and transformed into polyelectrolyte during the dissolution process. , In addition, chitosan has excellent biodegradability, good biocompatibility, outstanding antibacterial properties, and nontoxicity. It is widely used in biomedicine, agricultural fields, and industrial wastewater treatment …”

In recent years, the textile industry has been seeking to develop innovative products. It is a good choice to organically combine materials with superior functional characteristics and commercial textiles to form products with excellent performance. In particular, textiles made of biological functional materials are often beneficial to human health, which is an interesting research direction. As a biopolymer material, chitosan has the advantages of strong availability, low cost, excellent safety, outstanding performance, etc., particularly the antibacterial property, and has broad application prospects in the textile field. This review provides an overview of the latest literature and summarizes recent innovations and state-of-the-art technologies that can add value to textiles. To this end, preparation of chitosan fiber, synthesis of chitosan nanofiber, antibacterial activity of chitosan fiber, antibacterial activity of chitosan nanofiber, etc., will be discussed. Furthermore, the challenges and prospects of chitosan-based materials used in textiles are evaluated. Importantly, this review can not only help researchers understand the development status of antibacterial textiles, but also help researchers discover and solve problems in this field through comparative reading.

“…The coating agent needs to have water vapor barrier, antibacterial, a certain mechanical strength and stability, as well as easy decomposition. Meanwhile, it should not cause pollution to the human body or the environment (Kritchenkov et al, 2020). Sodium alginate can be isolated from brown algae, and has been widely studied for its non‐toxicity, biodegradability, and good compatibility.…”

In this study, we show that the shelf life of peeled waxy corn is prolonged when an edible coating agent made of sodium alginate, phytic acid, and nisin is applied. The purpose of this edible coating agent is to create flexibility in transportation methods and allow for a longer transportation time, while upholding its superior taste and quality. Results showed that the edible coating agent can reduce the weight loss rate by 1% and decrease the firmness by nearly 1500 g. It can also delay evaporation of soluble sugar content. Standardized tests were conducted to determine the film’s anti‐bacterial properties. Additionally, the water migration rate during storage was studied by low‐field NMR and found that it can effectively reduce the loss of free water. This creation of this edible coating agent will set a new direction in how food items will be preserved. Novelty impact statement The edible coating agent can extend the shelf life of peeling waxy corn and change the mode of transportation. The film can also reduce the weight loss rate of the peeling waxy corn, maintain its texture and soft taste and delay the decrease of soluble sugar, maintain its sweet taste. Through the determination of various indexes and water migration of waxy corn kernel during the storage, and the determination of membrane properties, the mechanism of the composite film was analyzed.
