Abstract

Lactic acid bacteria have been isolated from sourdough and could present important properties in food manufacturing as starter cultures and also as probiotics. This study evaluated the resistance of Lactobacillus paracasei strain isolated from sourdough to spray drying in the presence of reconstituted skim milk (RSM) and cheese whey (CW). The in vitro tolerance to acid, bile, sodium chloride (NaCl) and heat was studied to free and microencapsulated cells. The microcapsules moisture was determined, and the morphology was observed by scanning electron microscopy. The viability of free and microencapsulated cells decreased by 4.25 log CFU mL⁻¹and 1.00 log CFU g⁻¹, respectively, when exposed to pH 2.0 for 3 h. At pH 3.0, free cells decreased 0.3 log CFU mL⁻¹, while the microencapsulated form maintained its viability even after 3 h of exposure. After 12 h of exposure to 2 g 100 mL⁻¹bile salts, free and microencapsulated L. paracasei decreased 3.34 log CFU mL⁻¹and 2.17 log CFU g⁻¹, respectively. No significant cell loss was observed, for free and microencapsulated form when exposed to NaCl, and microencapsulated cells survived well for 15 min at 65 °C. Moisture content of microcapsules ranged from 4.30 to 4.77 g 100 g⁻¹. L. paracasei was found to possess desirable in vitro resistance to low pH and bile salts, and the microencapsulation in RSM and CW provided a cell protection against acidic pH and bile salts. This strain is good candidate for further investigation to elucidate its potential health benefits and in fermentation processes.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
