Selenium (Se) is an essential micronutrient for humans, and one of the new strategies to increase its intake is to fortify foodstuff with Se-bioaccessible species. This study aimed to produce Se-microparticles (selenate, selenite and Se-organic) using combined methods of microencapsulation; fortify commercial plant-based beverages (PBBs); evaluate the stability of microparticles; and estimate the bioaccessibility of Se and its contribution to the Recommended Daily Intake (RDA). Samples and bioaccessible fractions were submitted to acid digestion and Se levels (total and bioaccessible) were quantified by ICP-MS. The bioaccessibility of the Se-microparticles produced was estimated using an in vitro method under standardized conditions (INFOGEST). During the storage period, the microparticles maintained their stability and similar size. The PBBs fortified with Se-microparticles presented high bioaccessibility (77-94 %); being superior, in comparison, to the traditional fortification (Se-isolated salts). Thus, the results suggest promising perspectives for Se-supplementation in PBBs to meet nutritional needs effectively.

In this work, the lipidomic analysis on polar components of almond, coconut, and soy beverages was performed by liquid chromatography quadrupole time-of-flight mass spectrometry. A comparison with bovine milk was also performed. A total of 30 subclasses of polar lipids, belonging mainly to glycerophospholipids and sphingolipids, and a total of 572 molecular species were identified.

Rice milk is known for its wide range of beneficial effects on human health. Despite an increasing inclination towards rice drinks consumption, not much is known regarding the protein composition of commercial rice beverages. Hence, using a label-free quantitative proteomics approach we analyzed 9 different commercially available rice drinks and identified 259 rice proteins and 4 exogenous microbial α-amylases.

Many people in the Western world wish to reduce dietary reliance on animal-based and animal-derived foods. Plant-based (PB) meat and dairy alternatives can aid in this transition, but in the dairy category, only the milk market is well developed. Attention in the present research is, therefore, directed to PB cheese alternatives (PBCA), which were studied relative to dairy cheeses in a consumer taste test (central location setting) with 157 New Zealand (NZ) consumers conducted in 2023.

The use of lactic acid bacteria for developing functional foods is increasing for their ability to synthesize beneficial metabolites such as vitamin B (riboflavin, RF) and postbiotic compounds. Here, the spontaneous mutant FS54 B2 was isolated by treatment of the dextran-producing FS54 strain with roseoflavin. FS54 B2 overproduced RF (4.

Alcohol consumption is associated with both short- and long-term adverse effects, including hangover symptoms. The objective of this study was to examine the potential benefits of traditional beverages containing a combination of extract (HD) with either extract (HDPB) or glutathione yeast extract (HDGB) in abbreviating alcohol intoxication and mitigating hangover symptoms. A total of 25 participants between the ages of 19 and 40 who had previously experienced a hangover were evaluated in a randomized, double-blind, crossover, placebo (PLA)-controlled clinical trial.
