Kefirán como una nueva estrategia de valorización de recursos naturales para el desarrollo de envases de alimentos

Abstract

Cada vez más la industria de alimentos tiene como desafío el desarrollo y uso de materiales biodegradables provenientes de recursos naturales, bajo la adopción de un modelo de producción y consumo circular que contrarreste el problema medioambiental por el aumento acelerado en la producción de desechos plásticos provenientes principalmente del envasado de alimentos. En este sentido, la comunidad científica se ha enfocado en explorar nuevas fuentes de recursos naturales y renovables, como los biopolímeros derivados de fuentes alimenticias puesto que tienen la gran ventaja de ser también comestibles. El kefirán ha sido observado con gran interés para el desarrollo de envases de alimentos, puesto que al ser un exopolisacárido microbiano derivado de leche fermentada a partir de granos de kéfir, no presenta toxicidad, tiene actividad antimicrobiana, presenta un alto valor nutricional y otras características favorables. Además, gracias a su gran habilidad para formar películas y gran compatibilidad con plastificantes naturales como los azúcares, el uso de kefirán en la producción de películas comestibles y compostables puede dar lugar a envases adecuados con buenas propiedades mecánicas y físicas para desarrollar un envase de alimentos con características comparables a los provenientes de polímeros sintéticos.

The food industry is increasingly challenged by the development and use of biodegradable materials from natural resources under the adoption of a circular production and consumption model that counteracts the environmental problem due to the accelerated increase in the production of plastic waste, mainly from food packaging. In this sense, the scientific community has focused on exploring new sources of natural and renewable resources, such as biopolymers derived from food sources, since they also have the great advantage of being edible. Kefiran has been observed with a great interest in the development of food packaging since it is a microbial exopolysaccharide derived from milk fermented from kefir grains and has no toxicity,antimicrobial activity, high nutritional value, and other favorable characteristics. Moreover, thanks to its great film-forming ability and high compatibility with natural plasticizers such as sugars, the use of kefir in producing edible and compostable films can lead to suitable containers, with good mechanical and physical properties to develop food packaging with characteristics comparable to those from synthetic polymers.
