Prebiotic potential of drinks mixed with hemp fermented by probiotics
Plant-based beverages as a substitute for milk consumption are gaining remarkable interest in the food industry. Soy and rice drinks are the most studied and effective substitutes for milk. One untapped source is the hemp seed, which is a powerhouse of nutrients containing bioactive compounds, but the production of derivative drinks is limited. A new study suggests that prebiotic compounds, like volatile organic acids, improve the health potential of drinks.
What are probiotics?
Probiotics are living bacteria and yeast that are good for you, especially your digestive system. We generally think of them as germs that cause disease. But your body is full of bacteria, good or bad. Probiotics are often referred to as "good" or "helpful" bacteria because they help keep your gut healthy.
Researchers are trying to understand exactly how probiotics work and how they can keep you healthy.
- When you lose "good" bacteria in your body, for example after taking antibiotics, probiotics can help replace them.
- They can help balance your "good" and "bad" bacteria so that your body works as it should.
Difference between Prebiotics and Probiotics
PREBIOTICS are a special form of dietary fiber that acts as a fertilizer for the good bacteria in your gut. PROBIOTICS are live bacteria found in yogurt and other fermented foods. Bacteria PROBIOTICS must be kept alive to be active. They can be killed by heat, stomach acid, or just die over time.
The best probiotic drinks made from hemp seeds are those prepared with a bacterial consortium
The goal of this study to introduce new commercial drink formulations based on hemp seeds to ferment with probiotics like Lactobacillus fermentum, Lb. plantarum ou Bifidobacterium bifidum.
In this work, for the first time, the prebiotic activity of different drinks made from hemp seeds was evaluated by cultural and quantitative PCR methods (a particular method allowing to measure the initial quantity of DNA). In addition, to better describe the prebiotic potential, VOC alkenes and volatile organic acids were characterized by a metabolomic approach via GC-MS SPME. This approach consists of performing a complete and integrated analysis of the metabolites and proteins of the same biological sample. It allows the discovery of biomarkers and the characterization of metabolic pathways.
The obtained results have shown that hemp seed drinks have strong prebiotic activity, the ability to support the growth of probiotics and increase the content of certain bioactive compounds.
These results are in part due to the presence of different terpenes which inhibit the growth of enteropathogens and high levels of acetate, propionate and butyrate produced during fermentation which promote the growth of probiotics. Although the health potential of hemp seed is well known, derivative drinks have so far barely been processed and distributed. This work could therefore provide some basis for producing prebiotic and probiotic fermented hemp seed drinks.
