The anabolism of volatile compounds during the pasteurization process of sea buckthorn () pulp.

Unlabelled: Pasteurization (PS) causes the abnormal changes in volatiles and off-flavors in juices and limit the commercial production of juices. Herein, the first study on the biochemical reaction of volatile and nonvolatile compounds in response to PS factors during the process of sea buckthorn pulp (SBP) was evaluated. Processing conditions (mainly 80 °C for 20 min) had significant effects on the volatile and nonvolatile compounds.

A Perspective on Uniform Plating Behavior of Mg Metal Anode: Diffusion Limited Theory versus Nucleation Theory.

Utilizing metal anode is the most attractive way to meet the urgent demand for rechargeable batteries with high energy density. Unfortunately, the formation of dendrites, which is caused by uneven plating behavior, always threaten the safety of the batteries. To explore the origin of different plating behavior and predict the plating morphology of anode under a variety of operating conditions, multifarious models have been developed.

Selective Antagonism of Lactiplantibacillus plantarum and Pediococcus acidilactici against and in the Bacterial Community of Artemia nauplii.

Empiric probiotics are commonly consumed by healthy individuals as a means of disease prevention, pathogen control, etc. However, controversy has existed for a long time regarding the safety and benefits of probiotics. Here, two candidate probiotics, Lactiplantibacillus plantarum and Pediococcus acidilactici, which are antagonistic to and species , were tested on under conditions.

Screening and Mechanism of Novel Angiotensin-I-Converting Enzyme Inhibitory Peptides in Seed Meal: A Computer-Assisted Experimental Study Method.

Angiotensin-I-converting enzyme (ACE) inhibitors are used extensively to control hypertension. In this study, a computer-assisted experimental approach was used to screen ACE-inhibiting peptides from seed meal (XSM). The process conditions for XSM hydrolysis were optimized through the orthogonal experimental method combined with a database.

Deciphering the virulent Vibrio harveyi causing spoilage in muscle of aquatic crustacean Litopenaeus vannamei.

The muscle of aquatic crustaceans is perishable and susceptible to environmental contamination. Vibrio harveyi is a widely occurring pathogen in aquatic animals. Here, bath treatment with a virulent V.

Harsh Sensitivity and Mechanism Exploration of an Antibacterial Peptide Extracted from Walnut Oil Residue Derived from Agro-Industrial Waste.

Walnut ( L.) cake meal constitutes a significant amount of solid byproduct from the production of walnut oil, comprising more than 40% protein. However, it is usually not well utilized.

Impact of UHT processing on volatile components and chemical composition of sea buckthorn (Hippophae rhamnoides) pulp: A prediction of the biochemical pathway underlying aroma compound formation.

The effects of ultrahigh-temperature sterilization (UHT) on the volatile components and chemical composition of sea buckthorn pulp (SBP) were evaluated firstly. UHT had significant effects on the volatiles of SBP (mainly occurring at 140 °C for 2 s and 4 s), in which 140 °C for 2 s resulted in a decrease of 3.48% and 14.

A Novel Insight into Screening for Antioxidant Peptides from Hazelnut Protein: Based on the Properties of Amino Acid Residues.

This study used the properties of amino acid residues to screen antioxidant peptides from hazelnut protein. It was confirmed that the type and position of amino acid residues, grand average of hydropathy, and molecular weight of a peptide could be comprehensively applied to obtain desirable antioxidants after analyzing the information of synthesized dipeptides and BIOPEP database. As a result, six peptides, FSEY, QIESW, SEGFEW, IDLGTTY, GEGFFEM, and NLNQCQRYM were identified from hazelnut protein hydrolysates with higher antioxidant capacity than reduced Glutathione (GSH) against linoleic acid oxidation.

Roasting intervention for the volatile composition of three varieties of nuts originating from Torreya yunnanensis.

For the first time, the volatiles of three varieties of fresh and roasted Torreya yunnanensis nuts were investigated by solid-phase microextraction-gas chromatography-mass spectrometry. The results indicated that roasting had the greatest effect on the volatiles of millet capsules. Fresh nuts had many terpenes, esters, and aldehydes, while roasting led to the formation of pyrazines and furans.

Endogenous calcium attenuates the immunomodulatory activity of a polysaccharide from Lycium barbarum L. leaves by altering the global molecular conformation.

A heteropolysaccharide, LP5, was purified from Lycium barbarum L. leaves. It was identified as a calcium-rich polysaccharide (8.

Controlled synthesis of hollow octahedral ZnCoO nanocages assembled from ultrathin 2D nanosheets for enhanced lithium storage.

Hollow octahedral ZnCoO nanocages assembled from ultrathin 2D nanosheets are prepared through facile fast simultaneous coordinating etching and thermal processes.

Improved determination of phoxim residue in stored wheat by HPLC with DAD.

This article presents an improved method to detect the phoxim residual in whole wheat grain (not milled). The authors used petroleum ether (PE) as solvent to extract phoxim in darkness, and then determined it with high-performance liquid chromatography (HPLC) with diode array detector (DAD) at 280 nm. Use of PE improved the extraction efficiency of phoxim from grain samples over those obtained using acetone, recovery of 83.
