Stabilization of PUFA‐Rich Mayonnaise Against Lipid Oxidation: A Review of the Last Three Decades of Research

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Mayonnaise, a widely consumed oil‐in‐water emulsion, is highly susceptible to lipid oxidation due to its high content of polyunsaturated fatty acids (PUFAs) and the presence of pro‐oxidant factors such as low pH and iron from egg yolk. Over the past three decades, extensive research has focused on understanding oxidation mechanisms, analytical

Research on Evaporation Characteristics and Safe Storage Duration of Marine Liquid Hydrogen Storage Tanks Under the Coupling Effect of Heat Leakage and Sloshing

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Liquid hydrogen, a zero‐carbon and high–energy‐density fuel, is a promising option for future oceangoing vessels. During maritime transportation, onboard cryogenic tanks are exposed to ambient heat leakage and ship‐induced roll motion, which can trigger sloshing and fundamentally modify the coupled thermo‐fluid processes governing boil‐off and

Characterizing Heterogeneity in Post‐Consumer Rigid PP Packaging Waste: Implications for Object and Property‐Based Flake Sorting

Journal of Applied Polymer Science, EarlyView.
Commercial PP packaging grades span wide ranges in melt flow rate and stiffness, defining distinct application‐specific property spaces. Post‐consumer rigid PP products populate these spaces heterogeneously, with processing method and degradation shifting properties beyond virgin grade benchmarks.

Improved analysis of propylene oxide, propylene chlorohydrin and propylene bromohydrin

Julius-Kühn-Archiv, 2018
The benefits and deficiencies of several methods of analysis for PPO and PXH, including the aqueous extraction used in ASTA method 23.1 and the MTBE extraction method previously reported by the authors, will be discussed.

Real‐Time Biomass Estimation in High‐Density Yeast Fermentations Using Soft Sensor Modeling

Biotechnology and Bioengineering, EarlyView.
Accurate biomass measurements, both offline and online, are essential to improve prediction and control in yeast fermentation. This study develops regression‐based predictive models to correlate offline measurements (Dry Cell Weight and OD600 from a spectrophotometer) with online OD860 probe signals to provide accurate real‐time biomass estimations and

A Method for Optical Quantification of Local Oxygen Limitations in Multiphase Bioreactors

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Spatial oxygen limitation is a major source of physiological stress and metabolic, scale‐dependent heterogeneity in aerobic bioprocesses. In gas‐liquid stirred tank reactors, oxygen availability is governed by hydrodynamics and mass transfer and is therefore inherently non‐uniform.

Monitoring of oxygen in the gas and liquide phases of bottles of wine at bottling and during storage

OENO One, 2006
The assaying of oxygen in the headspace of a bottle combined with that of dissolved oxygen in the wine makes it possible to obtain the total oxygen per bottle.

Impact of Intermediate Wheatgrass an Adjunct Ingredient on the Chemical Composition and Development of Aroma Compounds in Sake Brewing

Cereal Chemistry, EarlyView.
ABSTRACT Background Replacing a portion of polished rice with intermediate wheatgrass (IWG) could diversify raw materials for sake, but its effects on composition and fermentation outcomes are not well characterized. The objective of this study was to quantify how adjunct form (whole vs.
