Xylo-oligosaccharide microparticles with synbiotic potential obtained from enzymatic hydrolysis of sugarcane straw

Abstract:

Synbiotic formulations and microencapsulation techniques have been explored in food industries to guarantee the viability of probiotic organisms; playing an important role in microbiota balance. Microparticles of alginate, gelatin and xylo-oligosaccharides (XOS) were produced by external gelation with the purpose of enhancing the survival rate of the probiotic L. acidophilus. XOS was obtained through enzymatic hydrolysis of xylan extracted from sugarcane straw, achieving more than 70% conversion and used for microparticle preparation. Microparticles containing 3% XOS provided greater cell protection during exposure to the gastrointestinal tract and during refrigerated storage; keeping 97.86 ± 0.44% of viability during 28 days of storage and enabling 87.50 ± 0.02% survival after digestive simulation. However, particles without XOS showed 84.49 ± 0.59% of viability after storage and 68.45 ± 0.03% after …
