Today more and more people pay attention to the problem of ecology and sustainable development. One of the most pressing issues is the problem of recycling and disposal of waste, including packaging materials. Today, many manufacturers are introducing new technologies and materials that help reduce the environmental impact on the environment. Biodegradable packaging is one of the ways to reduce the negative impact on the environment, because it does not accumulate in nature and decomposes naturally in a shorter time compared to plastic and combined materials. However, despite its advantages, it is not a universal solution to the problem of environmental sustainability. Its production can be more costly and complex than traditional packaging materials, and there are certain restrictions on its use. This article describes the results of a survey conducted among the residents of the Astrakhan region to identify consumer preferences for the use of biodegradable packaging and packaging materials. As a result of the analysis of the data obtained, the target consumer portrait was compiled, and the level of awareness of biodegradable packaging and packaging materials was determined. It was also revealed that the most popular biodegradable materials among consumers are biobaper and bioplastic, and the main factor in choosing packaging is ease of use. Despite the fact that more than 70% of the respondents preferred biodegradable packaging and packaging materials to traditional plastic products, only a few were willing to overpay for this type of packaging, which is a result of the socioeconomic situation in the Astrakhan region.

The purpose of the study is to establish the structure and properties of bioactive films based on pectin. The objects of study are films obtained on the basis of the structure-forming agent pectin with the addition of protein hydrolyzate as an active component. The microstructure of the produced films was determined using scanning electron microscopy; physicochemical properties (biodegradability, solubility, thickness, moisture content); bioactive properties (antioxidant capacity, ability to absorb DPPH radicals, content of polyphenols and flavonoids) spectrophotometrically. The addition of protein hydrolyzate to the composition of the pectin film changed its structural properties: a dense cellular network was formed, due to which the film became less susceptible to water and took longer to biodegrade in compost, and its thickness became smaller compared to the control. Moreover, both film samples completely turned into vermicompost after 2 weeks, which shows the high biodegradability of pectin films. The antioxidant properties of the films also improved: antiradical activity increased by 11 %, and antioxidant capacity by 49 % compared to the control sample. The introduction of protein hydrolyzate into the composition of a pectin film can solve a number of problems in the monocomponent composition of a pectin-based film, improve the structural characteristics and moisture resistance. The peptides included in the hydrolyzate, forming stable chemical bonds with pectin molecules, not only have a positive effect on the structure, but also increase antioxidant properties, which is promising for the production of bioactive food film coatings that can increase the shelf life of food products.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
