Microencapsulation of Lactobacillus plantarum DKL 109 using External Ionic Gelation Method

다국어 초록 (Multilingual Abstract)

The aim of this study was to apply the external ionic gelation using an atomizing spray device comprised of a spray gunto improve the viability of Lactobacillus plantarum DKL 109 and for its commercial use. Three coating material formulaswere used to microencapsulate L. plantarum DKL 109: 2% alginate (Al), 1% alginate/1% gellan gum (Al-GG), and 1.5%alginate/3% gum arabic (Al-GA). Particle size of microcapsules was ranged from 18.2 to 23.01 µm depending on the coat-ing materials. Al-GA microcapsules showed the highest microencapsulation yield (98.11%) and resulted in a significantincrease in survivability of probiotic in a high acid and bile environment. Encapsulation also improved the storage stabilityof cells. The viability of encapsulated cells remained constant after 1-mon storage at ambient temperature. The externalionic gelation method using an atomizing spray device and the Al-GA seems to be an efficient encapsulation technology forprotecting probiotics in terms of scale-up potential and small microcapsule size.
