“…Another recent study by Łozińska et al. (2020) also proved the encapsulation of FO by microencapsulation methodologies to protect against lipid oxidation in food systems. Moreover, in vitro studies in microencapsulation could control the release of active ingredients and would be an opportunity to fortify in functional foods.…”

“…The research to date has tended to focus on the encapsulation of individual oils (Łozińska et al., 2020; Piletti et al., 2019) rather than the combination with other oils (e.g., GO). Moreover, no previous study has investigated FO and GO encapsulation using in‐house developed microencapsulator and their fortification in functional bread to understand the variations of functional and organoleptic characteristics.…”

Hybridized microcapsules (MCs) containing fish oil (FO), garlic oil (GO), and their combination (FO + GO) were prepared and the effect of their fortification in bread was studied. Functional bread fortified with 5% hybrid MCs reported increased TBARS, but remained acceptable range over 7 days storage period at 4 ± 1°C (<25% RH) in LDPE (thickness: 0.05 mm) packaging. Textural analysis of bread samples demonstrated significantly (p < .001) increased hardness without changes in the cohesiveness and springiness of samples over 7 days at 4°C. No significant difference (p > .001) was found in the sensory profile of control bread versus GO and FO + GO hybrid MCs fortified bread. Bread fortified with FO + GO hybrid MCs scored better flavor and overall acceptability than bread with FO hybrid MCs. Thus, microencapsulation had shown the potential to reduce oxidation with acceptable textural and sensorial attributes of the bread. Practical applications In this study, fish oil, garlic oil, and their combination were encapsulated and then fortified in functional bread. The findings reported that the high encapsulation efficiency and in vitro bioavailability for encapsulated hybridized microcapsules. Additionally, fortified microcapsules in functional bread showed no change in textural and sensory attributes. Therefore, the study provides a basic to use encapsulation technology in oil foods to deliver functional ingredients through fortified foods.

“…Diluted HB (50 µL) was transferred into a HPLC vial and mixed with 50 µL methanol. The MS analysis was carried out according to the method described previously [ 85 ]. The following BS reference standards were used: sodium cholate (C; C6445, Sigma-Aldrich, Dorset, UK), sodium glycocholate (GC; G7132, Sigma-Aldrich), sodium taurocholate (TC; 86339, Sigma-Aldrich), sodium glycodeoxycholate (GDC; G9910, Sigma-Aldrich), sodium chenodeoxycholate (CDC; C8621, Sigma-Aldrich), sodium glycochenodeoxycholate (GCDC; G0759, Sigma-Aldrich), sodium taurodeoxycholate (TDC; T0875, Sigma-Aldrich), and sodium taurochenodeoxycholate (TCDC; T6260, Sigma-Aldrich).…”

Importance of Bile Composition for Diagnosis of Biliary Obstructions

Determination of the cause of a biliary obstruction is often inconclusive from serum analysis alone without further clinical tests. To this end, serum markers as well as the composition of bile of 74 patients with biliary obstructions were determined to improve the diagnoses. The samples were collected from the patients during an endoscopic retrograde cholangiopancreatography (ERCP). The concentration of eight bile salts, specifically sodium cholate, sodium glycocholate, sodium taurocholate, sodium glycodeoxycholate, sodium chenodeoxycholate, sodium glycochenodeoxycholate, sodium taurodeoxycholate, and sodium taurochenodeoxycholate as well as bile cholesterol were determined by HPLC-MS. Serum alanine aminotransferase (ALT), aspartate transaminase (AST), and bilirubin were measured before the ERCP. The aim was to determine a diagnostic factor and gain insights into the influence of serum bilirubin as well as bile salts on diseases. Ratios of conjugated/unconjugated, primary/secondary, and taurine/glycine conjugated bile salts were determined to facilitate the comparison to literature data. Receiver operating characteristic (ROC) curves were determined, and the cut-off values were calculated by determining the point closest to (0,1). It was found that serum bilirubin was a good indicator of the type of biliary obstruction; it was able to differentiate between benign obstructions such as choledocholithiasis (at the concentration of >11 µmol/L) and malignant changes such as pancreatic neoplasms or cholangiocarcinoma (at the concentration of >59 µmol/L). In addition, it was shown that conjugated/unconjugated bile salts confirm the presence of an obstruction. With lower levels of conjugated/unconjugated bile salts the possibility for inflammation and, thus, neoplasms increase.

“…PLS was applied to determine the most significant influence of the descriptor on the dependent variable. The PLS can be used for qualitative as well as for quantitative data, therefore, the PLS analysis was done according to Łozińska et al [ 79 ], and p -values were determined by (one-tailed) students t-test. The aim of the analysis of the data was to investigate the potential of which different descriptors influence the specific parameter (CMC, β, N a , and MSR).…”

We aim to advance the discussion on the significance of the conjugation of bile salts (BS) in our organism. We hypothesize that conjugation influences the rate of lipolysis. Since the rate of lipolysis is a compound parameter, we compare the effect of conjugation on four surface parameters, which contribute to the rate. Since deconjugation is due to gut microbiota, we hypothesize that microbiota may affect the rate of lipolysis. A meta-analysis of literature data of critical micelle concentration, β, aggregation number, and molar solubilization ratio has been performed for the first time. In addition, critical micelle concentration (CMC), interfacial tension, and lipolysis rate measurements were performed. It was found that the unconjugated BS in mixed micelles increases the antagonism between the BS, therefore, increasing the CMC. This correlated with the effect of unconjugated BS on the solubilization capacity of mixed micelles. The collected literature information indicates that the role of the BS and its conjugation in our organism is a key factor influencing the functioning of our organism, where too high levels of unconjugated BS may lead to malabsorption of fat-soluble nutrients. The experimental lipolysis results irrevocably showed that conjugation is a significant factor influencing the rate.
