Il calore ha un impatto negativo sui batteri probiotici.
La maggior parte dei ceppi probiotici, come Lactobacillus, Bifidobacterium e Streptococcus, sono sensibili al calore e richiedono la conservazione a freddo per sopravvivere in modo ottimale durante la conservazione.
Tuttavia, esistono formulazioni che consentono la conservazione a temperatura ambiente per periodi limitati per i seguenti ceppi: Lactobacillus acidophilus, Bifidobacterium bifidum, Lactobacillus casei, Lactobacillus rhamnosus, Saccharomyces boulardii.
La conservazione a temperature superiori a 25°C degrada la maggior parte dei ceppi probiotici.
Alcuni probiotici che formano spore, tuttavia, non richiedono la conservazione a freddo e possono sopravvivere a varie sfide ambientali, compresi i succhi gastrici. Questi includono:
Bacillus coagulans
Bacillus clausii
Bacillus subtilis
Clostridium butyricum
I ceppi di bacillo, in particolare, sono in grado di resistere a temperature fino a 70°C, tollerano i succhi gastrici e rimangono estremamente stabili..
Probiotics can be effectively protected from humidity by packaging them in aluminum foil or in bottles with integrated desiccants.
It is preferable that the packaging is not transparent, as sunlight could negatively impact the probiotic product.
High-quality, moisture-resistant packaging is essential for probiotic-containing products to ensure their stability and effectiveness.
Despite the wide variety of probiotics available, clinical trials are typically conducted only for individual bacterial strains to demonstrate their specific beneficial effects.
A product containing a mixture of many bacterial strains usually does not produce effects that are the sum of all the strains in the mixture. Moreover, mixed-strain products are rarely subjected to clinical testing due to the high cost involved.
Different bacterial strains in a single product can either complement or interfere with each other.
When clinical testing is lacking, the selection of an appropriate mix of bacterial strains often relies on expert opinion.
In general, making an informed choice involves understanding your specific probiotic needs, identifying a suitable strain, and opting for a single-strain or a product with a limited number of strains.
Certain vitamins and minerals can be reactive, potentially adversely affecting the stability or colonization of probiotics.
For individuals with brewer's yeast intolerance, it's important to note that some probiotic formulations introduce B-group vitamins derived from concentrated brewer's yeast.
