This study investigated the fortification of a carob-based kefir-like beverage (KLB) with whey permeate (WP) and oat flour (OF). The response surface method was used to show the effect of WP and OF concentrations on lactic acid bacteria and yeast cell densities, pH, total titratable acidity (TTA), total phenolics content (TCP), DPPH radical scavenging activity, and overall acceptability (OA) in KLB. The statistical design provided thirteen formulations where OF concentration varied from 3% to 5% and WP from 10% to 15%. The enrichment of carob pods decoction with WP and OF had a positive effect on biomass production. Overall fermentation was shown to increase TPC of KLB. Furthermore, OF supplementation led to the higher levels of TPC and antiradical activity. WP negatively affected OA at linear and quadratic levels, whereas no effect of OF was observed at the linear level. The optimum point was found by using WP at 11.51% and OF at 4.77%. Optimized KLB resulted in an enrichment of bioavailable phenolics derivatives and highly digestible proteins.

Oats are gluten-free cereals rich in dietary fiber, -glucans, phenolic acids, flavonoids, carotenoids, vitamin E, and phytosterols. They have been used in traditional medicine for centuries to treat hyperacidity, acute pancreatitis, burns, and skin inflammation. This study assessed the nutritional and phenolic profile of oat flour (OF) and ground oat husks (OHs) from white, brown, and black hulled oat genotypes, as well as the antioxidant and antimicrobial activity of their extracts.

A competitive direct enzyme-linked immunosorbent assay (dc-ELISA) was developed for the detection and quantification of scopolamine (SCO) in wheat flours and cereal samples (multigrain, oat and barley). The limit of quantification (IC) of the established method was 6.00 ± 1.

The role of water-extractable (WE) cereal flour constituents, and particularly WE proteins, in determining bread dough gas cell stability and bread specific volume (SV) remains ill-understood. We investigated the impact of compositionally diverse cereal flour aqueous extracts on bread SV, dough extensional rheology, and dough gas cell size distribution. To this end, aqueous extracts from wheat, rye, and defatted oat flours were either used as such, or their composition was modified by dialyzing out (i) low molecular mass constituents or (ii) both low molecular mass constituents and enzymatically hydrolyzed carbohydrates.

Unlabelled: A simple method based on solid-liquid extraction with a low-temperature partition (SLE/LTP) and analysis by gas chromatography coupled to mass spectrometry (GC-MS) was optimized and validated for determining residues of the pesticides triadimenol, flutriafol, λ-cyhalothrin, difenoconazole, and azoxystrobin in oat flour. A factorial design was employed to optimize the technique and establish the best conditions for the simultaneous extraction of the analytes. Acetonitrile-sample extraction and its 4 h freezing made it possible to recover the pesticides and clean the extracts in a single step.
