Summary: In this study, a powerless, gas-permeable, flexible and transparent ascorbic acid biosensor based on carbon micromesh electrode was developed. The biosensor showed excellent performances including high transmittance, wide detection range, low limit of detection, good selectivity, and long-term storage stability. By integrating a pH-sensing electrode, the analysis of ascorbic acid can be corrected. The biosensor demonstrated good sensitivity and practicability towards wearable electronics in the detection of artificial tears.

Summary: Alkaline phosphatase (ALP) is a zinc-containing metalloprotein widely distributed in mammalian tissues that plays a vital role in clinical diagnosis. It is widely used for signal amplification in enzyme-linked assays and is a promising biomarker for disease diagnosis. Assays using L-ascorbic acid 2-phosphate (AAP) as a substrate have been developed to detect ALP activity, providing new insights into the construction of advanced sensing platforms for clinical diagnosis.

Summary: The study investigated the effects of pH, sugar addition, and thickening agents on furan levels in strawberry jam, with findings showing that fructose produces more furans than sucrose and glucose, and xanthan gum reduces furan levels significantly. Kinetic data revealed the degradation of ascorbic and dehydroascorbic acid follows first-order kinetics, while furan formation rate follows zero-order kinetics. The study suggests the potential to decrease furan formation in canned strawberry jams through process optimization and xanthan gum addition.

Summary: This study reports a simple and rapid colorimetric immunoassay for the determination of carcinoembryonic antigen (CEA) using Fe2O3 nanoparticle-based chromogenic substrate system. The assay is based on the rapid coordination of ascorbic acid 2-phosphate (AAP) and iron (III), resulting in color development. Fe2O3 nanoparticle is used as a label in a sandwich-type immunoassay, and the absorbance of the reaction solution is positively correlated with antigen concentration. The method shows good performance for CEA detection, with a wide detection range and a low detection limit, as well as acceptable repeatability, stability, and selectivity.

Summary: The study presents techno-economic analyses of high-yield production of furans from mixed-sugar hydrolysates using a hybrid enzyme-chemo-catalytic process. Through a series of reactions and extractions, lignocellulosic mixed-sugar hydrolysates are converted to HMF and furfural, providing a promising price point for industrial production. Sensitivity analyses show that feedstock sugar cost and overall furan yield are key factors influencing the minimum furan selling price, with improvements in these parameters potentially making the price competitive for fuel and polymer precursor applications.

Summary: We have developed a novel noninvasive wearable biosensor that can simultaneously detect multiple key biomarkers in human tears. The biosensor is designed as a convenient eye patch that can be easily worn under the eyes. Different sensing regions on the eye patch are modified with specific chromogenic reagents to selectively determine pH, protein, ascorbic acid, and glucose in tears. The color signals from each sensing region on the eye patch are captured and analyzed using a smartphone, and a cloud model based on the internet of things concept is recommended for data analysis. Tear detection using this method shows good correlation with parallel measurements using assay kits, demonstrating the potential and versatility of this noninvasive eye patch biosensor for various tear biomarkers.

Summary: Commercial niobium and synthesized zirconium phosphates were tested as water-tolerant acid catalysts in the hydrothermal conversion of bio-based substrates. The different acid properties of the two catalysts enabled the production of target products with high yields, such as furanic compounds and cellulose-derived sugars. These findings suggest the potential for cascade production of value-added bio-products using the synthesized hydrolysates rich in C5 and C6 carbohydrates.

Summary: The study found that the minimum, optimum, and maximum growth temperatures of Bacillus cereus in egg fried rice were 11.8, 40.8, and 50.6 degrees C, with an optimum specific growth rate of 2.4 per h. The OSDA method was proven to be an effective way of quickly developing predictive models and estimating kinetic parameters. According to the model, the growth of mesophilic Bacillus cereus is unlikely to occur if the food is stored below 10 degrees C.

Summary: This study investigated the competition between lactic acid bacteria (LAB) and Listeria monocytogenes during the fermentation and drying process of meat sausages. The results showed that LAB suppressed the growth of L. monocytogenes during simultaneous fermentation and drying. A competition model was developed to accurately predict the growth of both LAB and L. monocytogenes in this process. This is important for improving the safety of semi-dry and dry fermented meat sausages.

Summary: This study investigated the growth kinetics of foodborne pathogen B. cereus during the commercial production of liquid egg yolk using PLA(2) treatment. The results showed that B. cytotoxicus NVH391-98 can grow prolifically at 50 degrees C, with estimated minimum, optimum, and maximum temperatures of 16.7-18.5, 47.8-48.1, and 52.1-52.4 degrees C, respectively. The dynamic model was validated with isothermal curves and it was found that holding the temperature below 15 degrees C or above 55 degrees C can effectively prevent the growth of B. cytotoxicus in egg yolk.
