A Fast Method for Selecting Bio Sourced Materials of Interest in a Candle Formulation

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT As consumer demand shifts towards more sustainable and nontoxic alternatives, the candle industry is exploring unconventional bio‐based and recycled materials as substitutes for paraffin. Four raw materials, that is rice bran wax (RBW), sugarcane wax (SCW), hydrogenated rapeseed oil (HRO), and waste cooking oil (WCO) were assessed based on ...

Compositional Characterization, Quality Parameters, and Physicochemical and Bioactive Properties of Pequi (Caryocar brasiliense) Oils From Xingu and Cerrado in Mato Grosso, Brazil

Journal of the American Oil Chemists' Society, EarlyView.
Cerrado oil is richer in MUFA and antioxidant compounds, while Xingu oil shows higher SFA and enhanced oxidative stability, reinforcing the potential of pequi oil as a sustainable bioactive ingredient. ABSTRACT Pequi (Caryocar brasiliense) is a native fruit widely distributed in Brazilian biomes, specially in Cerrado, known for its high oil yield and ...

Exploring the Application of Waxes and Their Mixtures Oleogels in Ice Cream

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT The objective of this work was to produce ice cream using waxes oleogels, aiming to improve its nutritional value while maintaining its physical‐chemistry characteristics. Five ice cream formulations were manufactured using (1) milk fat, (2) canola oil, and (3–5) canola oil‐oleogels. The oleogels were produced with beeswax (BEW), carnauba wax (

Discrimination of Lipid Hydroperoxide Positional Isomers Using SFC–MS/MS With Sodium Ion: Its Application to Evaluating the Oxidation Mechanisms of Oxidized Oils

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Advanced lipid profiling relies on liquid chromatography–tandem mass spectrometry (LC–MS/MS), but long analysis times remain a challenge. Supercritical fluid chromatography (SFC)–MS/MS using supercritical carbon dioxide offers a faster and more environmentally friendly alternative.

Effects of Replacing Alfalfa Hay With Barley Silage in High‐Concentrate Diets: Chewing Behavior, Ruminal Fermentation, Total‐Tract Digestibility, and Milk Production of Dairy Cows in Mid‐Lactation Phase

Animal Research and One Health, EarlyView.
We assessed lactation productivity in dairy cows when replacing alfalfa hay with barley silage. A 50% replacement increased feed intake, whereas total replacement improved nutrient conversion to milk. Barley silage can effectively replace alfalfa hay, enhancing sustainability and resilience in dairy production amid forage quality constraints and market

Synergistic Enhancement of Antioxidant Activity in Arbutus unedo Leaf Extract by Biological Fluids: Implications for Functional and Nutraceutical Applications

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT This study examined the effect of biological fluids (saliva, blood plasma, and urine) on the antioxidant capacity of an aqueous extract derived from Arbutus unedo leaves. The extract displayed a concentration‐dependent reducing activity in the ferric reducing power assay (IC50 = 292 ± 7.54 µg/mL) and phosphomolybdenum assays (IC50 = 461.67 ± 4.
