Department of Food Science and Nutrition, Faculty of Food Engineering, University of Campinas, Campinas, SP, Brazil. Electronic address:
This study evaluated the impact of fermentation with Lactobacillus acidophilus pre-subjected to acid, osmotic, and oxidative stress conditions on the production of metabolites and the bioaccessibility of nutrients and bioactive compounds in fermented milks and yogurts. The products were added with orange bagasse (additional calcium - Ca source) and buriti pulp (carotenoids source). Gas chromatography coupled with mass spectrometry (GC-MS) and nuclear magnetic resonance (NMR) were used to analyze the volatile and non-volatile compounds metabolites from fermentation, respectively.

Department of Food Science, University of Copenhagen, Rolighedsvej 26, 1958 Frederiksberg, Denmark. Electronic address:
The efficiency of ultrafiltration (UF) of acidified skim milk (SM) is impaired by protein aggregation and mineral scaling. The aim of this study is to assess the potential of acidification by electrodialysis with bipolar membranes (EDBM), in comparison with citric acid (CA), prior to the UF process on filtration performance, fouling and composition of the protein concentrates. Electro-acidification, facilitated by a water-splitting reaction, decreased the pH of milk to ∼ 5.

Background: Renal functional reserve (RFR) measures the difference between the stimulated glomerular filtration rate (GFR) and the baseline GFR to detect early signs of renal functional decline. The protein load test (RFR-T) is the gold standard for RFR assessment but is a complicated procedure. Renal intraparenchymal resistance index (RRI) variation test (DRRI-T) is a non-invasive method to measure renal function reserve using ultrasound.

The aim of this work was to study the effects of two LAB strains on the bioaccessibility (BA) of minerals after the fermentation of pistachio-based beverages. The beverages were made with two varieties of pistachio (Argentina, AP and Italian, IP). Aliquots were inoculated with 10 CFU of two different LAB strains and fermented for 24 h at 28 °C.

Aim: The present study was conducted to produce a new carrier containing whey protein isolate-basil seed gum (WPI-BSG) conjugate to achieve superior physicochemical stability of emulsions containing vitamin D (Vit-D).
Methods: Zeta-potential and particle size analysis, spectrophotometric method, encapsulation efficiency, loading capacity and dialysis bag method were used to examined physicochemical stability and Vit-D release from the emulsions.
Results: The conjugate-stabilised emulsion showed maximum encapsulation efficiency (87.
