Cultivar affects browning susceptibility of freshly cut star fruit slices

Scientia Agricola, 2006
Consumption of freshly-cut horticultural products has increased in the last few years. The principal restraint to using freshly-cut carambola is its susceptibility to tissue-browning, due to polyphenol oxidase-mediated oxidation of phenolic compounds ...

4-Deoxyaurone formation in Bidens ferulifolia (Jacq.) DC.

PLoS ONE, 2013
The formation of 4-deoxyaurones, which serve as UV nectar guides in Bidens ferulifolia (Jacq.) DC., was established by combination of UV photography, mass spectrometry, and biochemical assays and the key step in aurone formation was studied.

Soil Response to Agricultural Land Abandonment: A Case Study of a Vineyard in Northern Italy

Agronomy, 2021
Agricultural land abandonment is an emerging problem in European Union (EU), and about 11% of agricultural EU land is at high risk of abandonment in the coming 10 years. Land abandonment may have both positive and negative effects in ecosystems.

Effects of Plasma‐Activated Water and Konjac Glucomannan‐Based Edible Coating on the Storage Quality of Fresh Banana (Musa sapientum L.)

ChemFoodChem, EarlyView.
ABSTRACT This study evaluated the effects of plasma‐activated water (PAW), konjac glucomannan (KGM)‐based edible coating, and their combined treatment on the postharvest quality of fresh bananas stored at 20°C for 12 days. Four treatments were applied: control, PAW, coating, and PAW+coating.

Fermentation‐Induced Modulation of Polyphenolic Contents and Medicinal Activities in Annona squamosa Seeds

Food Chemistry International, EarlyView.
The study compared the medicinal activities of polyphenols from fermented and unfermented seeds of Annona squamosa. The polyphenols were extracted and subjected to standard analysis. The major phenolic components of the fermented polyphenols and the unfermented polyphenols were found to be 4‐hydroxybenzoic and 4‐hydroxyphenylacetic acid, respectively ...

Molecularly imprinted polymers based electrochemical sensors for biomarker detection in biofluids

InfoScience, EarlyView.
This review systematically summarizes the evolution of molecularly imprinted polymer electrochemical sensors from bulk structures to advanced nano‐imprinted architectures. It decouples the complex matrix effects of clinical biofluids and evaluates interfacial engineering strategies for anti‐biofouling.

Integrated one‐pot CRISPR‐Cas detection: Addressing strategies and future prospects

Interdisciplinary Medicine, EarlyView.
Integrated one‐pot CRISPR‐Cas detection significantly simplifies workflows, reduces cross‐contamination risks, and shortens turnaround times, making it highly suitable for point‐of‐care testing (POCT) and resource‐limited settings. Key challenges include system compatibility issues between Cas proteins and isothermal amplification, limited multiplexing

Substrate specifity and inhibitors of polyphenol oxidase in aspect of darkening of fresh and frozen mushrooms (Agaricus bisporus (Lange) Sing.)

Acta Agrobotanica, 2013
Activity of mushroom polyphenol oxidase (PPO) toward 6 substrates and inhibitory effect of cysteine, 2-mercaptoethanol, benzoic acid and sodium metabisulphite were determined. The o-diphenols which appeared to be the best substrates were: catechin, DOPA (

Influence of different drying techniques on the quality and physicochemical properties of Ghana‐sourced turmeric (Curcuma longa L.) samples

JSFA reports, EarlyView.
Abstract Background This study evaluated the influence of four drying techniques—freeze drying (FZD), microwave drying (MCD), oven drying (OVD), and sun drying (SUD)—on the bioactive, nutritional, and physical properties of turmeric. Using standard analytical procedures, the samples were examined for antioxidant activity (DPPH and ABTS assays), total ...

Characterization of the Ornithine Hydroxylation Step in Albachelin Biosynthesis

Molecules, 2017
N-Hydroxylating monooxygenases (NMOs) are involved in siderophore biosynthesis. Siderophores are high affinity iron chelators composed of catechol and hydroxamate functional groups that are synthesized and secreted by microorganisms and plants. Recently,
