Survivability of probiotics encapsulated in alginate gel microbeads using a novel impinging aerosols method

摘要: Encapsulation of probiotic bacteria in cross-linked alginate beads is major interest for improving the survivability harsh acid and bile environment also food matrices. Alginate micro (10-40 mu m) containing probiotics Lactobacillus rhamnosus GG acidophilus NCFM were produced by a novel technique based on dual aerosols solution CaCl(2) cross linking solution. Extruded macro (approximately 2 mm diameter) conventional method offered comparable protection to L. high environment. Chitosan coating resulted significant increase survival time from 40 120 min condition reduction cell numbers was confined 0.94 log over this time. are more effective than protecting L against bile. similar extended 90 at least min.
