Many different techniques are applied for the extraction of these viable compounds such as UAE, MAE, Autohydrolysis and HHP. A conjugated system of techniques like ultrasound and microwave assisted extraction results in better extraction yield and makes up for every inadequacy. There are various spheres of studies involved in establishing any prebiotic ingredient. In vitro and In vivo studies are carried out to check the efficacy and safety of a prebiotic compound. A prebiotic portion also influences its safety profile and is recommended 2.5-10 g/day. Due to the gleaming qualities of prebiotic, they have made a strong way to the market. Prebiotics + Probiotic products are been extensively researched and developed in the market with claiming health benefits to human body.
