Approaches for enhancing the viability of probiotics: a review
Abstract
Purpose
The purpose of this article is to attempt to highlight various approaches for enhancing the viability of probiotics, with special emphasis on micro‐encapsulation.
Design/methodology/approach
Various techniques, such as selection of acid and bile resistant strains, use of oxygen impermeable packaging materials, two‐step fermentation, stress adaptation, inclusion of micro‐nutrient, sonication of bacteria and micro‐encapsulation, which could be employed for maintaining or enhancing probiotic viability are discussed, with special emphasis on micro‐encapsulation.
Findings
Probiotics lose their viability during gastro‐intestinal transit due to unfavorable intestinal environment. Amongst diverse techniques micro‐encapsulation could confer protection to the probiotics both in the product as well as in the gastro‐intestinal environment.
Originality/value
The paper shows that micro‐encapsulation of probiotics renders them stable both in the product as well as in the intestinal environment and application of encapsulated probiotics would result in a product with greater prophylactic activities.
