New characterization of probiotics, prebiotics, synbiotics, and/or postbiotics

What is it about?

It's a book chapter reporting the application of a rapid microcalorimetric technique to control the quality and integrity of powder samples of products (supplements, ingredients, foods, etc.) containing prebiotics, probiotics, synbiotics, and/or postbiotics. The method combines thermogravimetry and differential scanning calorimetry measurements, providing thermophysical profiles and specific data (fingerprints) of samples. More than 100 samples have been analyzed and the paper show some examples and representative strains.

Why is it important?

It is important for many reasons: 1. This is the only method that enables us to simultaneously provide unique and precise data on probiotics and prebiotics/active compounds in terms of analytical and biological compositions, thermostability, and fingerprints of powder samples, whatever their complexity, nature, and origin; 2. The method only requires small amount of sample ( ± 10 mg), which can be analyzed directly without pretreatment; 3. It's very reproducible and sensitive, and convenient for a high throughput approach.
