“…The use of spray-drying for microencapsulation is another widely used technique due to its low-cost and easy application [19]. Spray-drying technique is used in the food industry for microencapsulating juice, pulp, and vegetal extracts [20,21], probiotics [22], and fish oil [23].…”

Microencapsulation is a group of technologies aiming to produce small particles called microcapsules that can be released at a specific speed under certain conditions. Microencapsulation technology is used in the pharmaceutical, agrochemical, and food industries; however, microcapsule production is most challenging for applications in the food industry owing to the high costs of the technique, which may make the final product too expensive. Common methods for microencapsulation include spray-drying and coacervation, and different wall materials and filling materials can be used for both techniques. In this review, we summarize current methodologies used for microencapsulation, with a focus on applications in the food industry.

A microencapsulação consiste na técnica de envolver materiais sólidos, líquidos ou gasosos em pequenas cápsulas que liberam seu conteúdo sob condições controladas. Esta tecnologia tem sido utilizada para manter a estabilidade de probióticos durante o processamento e estocagem dos alimentos, além de aumentar a resistência no decorrer do trato digestório, possibilitando que estes cheguem ao intestino grosso com condições de sobrevivência e colonização. Durante o processo de microencapsulação, a escolha do material encapsulante é uma etapa de grande importância e deve se basear nas características do composto bioativo, na aplicação pretendida e no método de formação das partículas. Existem diversas técnicas que têm sido empregadas na elaboração de microcápsulas e a seleção do método mais adequado deve ser realizada com base nas propriedades físicas e químicas do material que será encapsulado e do agente encapsulante, analisando-se a finalidade de aplicação do ingrediente alimentício. O presente trabalho visa à revisão dos principais métodos e agentes encapsulantes utilizados na microencapsulação de micro-organismos probióticos. PALAVRAS-CHAVE:bactérias ácidos láticos; encapsulação; estabilidade.

“…Controlled release systems of active substances have emerged from the need to protect or isolate active substances from external interferents, as well as to enable the release of the active substance at specific sites, at controlled rates and/or in specific conditions . Recently, particles immobilization research such as nutrients or microbial cell has been conducted in order to improve the petroleum hydrocarbons biodegradation and others contaminants …”

The risks of environmental damage are inherent in oil activities, being a constant concern to our modern society. Among the remediation strategies, the biological one is safer and more inexpensive compared to physic‐chemicals approaches. Bioremediation can be enhanced using biodegradable polymers as coating materials of the nutrient release systems. However, some of these polymers can be improved using electromagnetic radiation, able to modify their properties, such as, molar mass, changing the materials physicochemical behavior. Thus, immobilizing urea in poly (butylene succinate) (PBS) matrix, producing a petroleum bioremediation tool was the primary goal in the paper herein. The composites were obtained by melting at 110 °C with subsequent application of gamma (γ) radiation at doses of 15, 25, 50, and 75 kGy. The obtained results allowed to infer that the increase of the γ radiation doses improved the immobilization, thus reducing the immediate urea release. Besides that, the preliminary biodegradation results showed that the highest rates of hydrocarbon reduction at the end of the analysis period were reached using the material irradiated at 25 kGy. These results are encouraging and proved that irradiated PBS‐urea systems could be used as oil spill disasters tool.
