Summary of "Layer (whey protein isolate) -by-layer (xanthan gum) microencapsulation enhances survivability of L. bulgaricus and L. paracasei under simulated gastrointestinal juice and thermal conditions."

In the study, Lactobacillus delbrueckii subsp. bulgaricus (L. bulgaricus) and Lactobacillus paracasei subsp. paracasei (L. paracasei) were isolated from food products and identified. The probiotics were co-encapsulated by emulsification technique with transglutaminase-induced gelation of whey protein isolate (WPI). A double layer was formed by xanthan gum (XG). The survival of both free and microencapsulated cells in each step was enumerated. The results showed that high entrapment yield (86.36 ± 1.07%) was achieved, WPI-XG provided significant protection for cells in simulated gastric juice and bile tolerance tests compared with free cells. Besides, the survivability under thermal condition also strengthened. During freeze-drying process, the survival was improved and naked cells cannot be seen on microcapsules surface when trehalose was added into WPI solution as a lyoprotectant. Additionally, the structure changes of WPI/XG in the encapsulation process were investigated by Fourier transform infrared spectrophotometer (FT-IR) and the thermal properties were studied by differential scanning calorimetry (DSC).

Medical and Biotech [MESH] Definitions

The external, nonvascular layer of the skin. It is made up, from within outward, of five layers of EPITHELIUM: (1) basal layer (stratum basale epidermidis); (2) spinous layer (stratum spinosum epidermidis); (3) granular layer (stratum granulosum epidermidis); (4) clear layer (stratum lucidum epidermidis); and (5) horny layer (stratum corneum epidermidis).

Synthetic material used for the treatment of burns and other conditions involving large-scale loss of skin. It often consists of an outer (epidermal) layer of silicone and an inner (dermal) layer of collagen and chondroitin 6-sulfate. The dermal layer elicits new growth and vascular invasion and the outer layer is later removed and replaced by a graft.

The muscles of the PHARYNX are voluntary muscles arranged in two layers. The external circular layer consists of three constrictors (superior, middle, and inferior). The internal longitudinal layer consists of the palatopharyngeus, the salpingopharyngeus, and the stylopharyngeus. During swallowing, the outer layer constricts the pharyngeal wall and the inner layer elevates pharynx and LARYNX.

Layers of protein which surround the capsid in animal viruses with tubular nucleocapsids. The envelope consists of an inner layer of lipids and virus specified proteins also called membrane or matrix proteins. The outer layer consists of one or more types of morphological subunits called peplomers which project from the viral envelope; this layer always consists of glycoproteins.

Nerve cells of the RETINA in the pathway of transmitting light signals to the CENTRAL NERVOUS SYSTEM. They include the outer layer of PHOTORECEPTOR CELLS, the intermediate layer of RETINAL BIPOLAR CELLS and AMACRINE CELLS, and the internal layer of RETINAL GANGLION CELLS.
