Stabilization of Lactobacillus sp. with enhanced thermal resistance by spray-drying

[EN] Combining biotechnology and encapsulation by spray-drying is possible to obtain microorganisms-based products in powder format without losing viability. A methodology based on the improvement of the thermal stress resistance of selected strains of Lactobacillus sp. and subsequent culture stabilization by spray-drying by optimizing the process parameters and using thermal protectant materials has been developed. The results obtained showed that the final product kept the viability of the initial culture in addition to be a solid, powdery and ease-to-handle product.Rivera, D.; Valverde, M.; Valera, A.; Torrejón, A.; Espí, J.; Gómez, E.; Ruiz, B.
