Probiotics have awakened a great interest in the scientific community for their potential beneficial effects on health. Although only allowed by the European Food Safety Agency as a nutrition declaration associated with the improvement of lactose digestion, recent in vitro and in vivo studies have demonstrated their varied beneficial effect for the improvement of certain pathologies. However, probiotics face stability and viability challenges, which make their delivery difficult in sufficient quantities for these effects to be observed. Thus, there is a dire need for the development and implantation of innovative technological protection procedures. In this sense, encapsulation rises as a widely applied technique, offering additional advantages. In the present study, a systematic review was conducted for the evaluation of the main encapsulation technologies applied in literature, considering operating conditions, probiotics, and encapsulation efficacy. For this purpose, several conditions are evaluated: a) the characteristics, storage conditions and viability of probiotics; b) evaluation and comparison of the probiotic stabilization for the main encapsulation methods; and c) co-encapsulation with potential bioactive molecules as a new alternative for improving cell viability. This evaluation revealed the efficacy of seven encapsulation techniques on the improvement of the stability and viability of probiotics.

Ulcerative colitis (UC) is a chronic inflammatory bowel disease initially treated with mesalazine (5-ASA). However, its effectiveness is limited by rapid absorption, low colonic concentration, and exacerbation of dysbiosis. Probiotics can mitigate dysbiosis if they survive the acidic conditions of the stomach.

Background: In recent years, consumer preference for symbiotics containing live bacteria has surged, driven by the acknowledged health benefits. Wheat residue from beer brewing, rich in dietary fiber, remains an unexplored prebiotic raw material for developing vegan probiotic powdered products. Concerns about ambient conditions, dehydration and drying affecting bacterial cell viability prompt the investigation of protective agents (maltodextrin, l-arabinose, casein, whey protein, skimmed milk) and fluidized bed granulation microencapsulation for enhancing the survival rate of Lactiplantibacillus plantarum NKUST 817.

To evaluate the combination effects of highland barley polysaccharides (HBP) and low-frequency static magnetic field (LF-SMF) treatment on the structure and properties of acid-induced casein (CS) coacervates, this study conducted a comprehensive investigation at various stages- before, during, and after coacervation-for the first time. Compared with native CS, adding HBP caused CS to denature owing to hydrophobic and electrostatic interactions, and LF-SMF treatment further promoted these changes. During the acidification (pH 7.
